Unmarried Partner Life Insurance Calculator (2026): The Coverage Gap No One Models
Everything in the American safety net is written in terms of marriage. Social Security’s survivor program, the $255 lump-sum death payment, the unlimited marital deduction in the estate tax, ERISA’s spousal pension protections, the spousal rollover for an inherited IRA, and the intestate share that keeps a home out of probate are all built on a legal relationship. An unmarried partner, no matter how long the two of you have lived together, is a legal stranger to all of it.
That is why the standard needs calculators understate the problem for cohabiting couples. A DIME or income-multiple formula measures what a household loses. It does not measure what a partner loses that a spouse would never lose: the survivor benefit that does not exist, the pension income that stops at the grave, the home that passes to your siblings under state intestacy, and the inheritance tax that six-figure transfers to a non-relative can trigger. This calculator prices the whole gap, including the pieces that come from the word “unmarried” rather than from the size of your income.

Where the money runs out: your partner’s support deficit by period
Social Security pays a surviving spouse for life and a widowed parent for the dependent years. An unmarried partner receives nothing, so 100 percent of this ladder is the couple’s own responsibility.
| Period after your death | Income needed | Social Security to your partner | Shortfall in the period | Cumulative shortfall |
|---|
How the coverage number moves with the support window you choose
A partner in their 30s needs a different answer than a partner at 62. The income component is escalated at 3 percent a year for inflation, which is why the curve is steeper than a flat multiple of salary.
| Years of support | Income replacement | Coverage after lump sums | Term length that matches it |
|---|
Educational estimates only. The income component is escalated 3 percent a year for inflation. Lump-sum obligations and inheritance tax are added at face value with no present-value discount. State inheritance tax rates are simplified: Pennsylvania 15 percent to non-relatives, Maryland 10 percent flat on collateral heirs, Nebraska 15 percent above a $25,000 exemption, New Jersey 15 percent to $700,000 and 16 percent above, Kentucky modelled at 11 percent within a 6 percent to 16 percent schedule. Tennessee, Connecticut, Iowa and the other states that once taxed inheritances no longer do. Premiums are quoted individually and are never guaranteed.
What an unmarried partner is not entitled to in 2026
The largest single number in this calculation is not the income replacement figure. It is the safety net that a spouse receives automatically and a partner receives not at all. Start with Social Security. Under 20 CFR 404.335, a widow or widower benefit requires a marriage that lasted at least nine months immediately before the death, with narrow exceptions for accidental death, a death in the line of military duty, a prior nine-month marriage to the same person, or being the natural parents of a child together. There is no length of cohabitation that converts into eligibility on its own. The spousal benefit at 20 CFR 404.330 is written the same way.
The same wall blocks the one-time payment. The $255 lump-sum death payment goes to a surviving spouse who was living in the same household, or, if no spouse qualifies, to an eligible child. It has not been increased since 1954, and a surviving unmarried partner is not on the list. A surviving divorced spouse is not on the list either.
Two doors do exist, and they are worth checking rather than assuming. First, if your state recognizes common-law marriage and your relationship meets that state’s test, Social Security looks to state law and can treat the relationship as marital. Second, the regulations look to state intestacy law as well: where a registered domestic partner or civil union partner would receive the share a spouse takes, SSA can treat the relationship as marital for benefit purposes. California is the clearest example, because Family Code section 297.5 gives a registered partner a spouse’s intestate share. Both routes require the nine-month duration rule, both are state dependent, and neither is automatic. If you are registered anywhere, raise it with SSA directly.
| Protection | Married spouse | Unmarried partner |
|---|---|---|
| Social Security survivor benefit at 60 | 71.5 percent of your benefit, rising to 100 percent at full retirement age | Nothing, unless a common-law or registered-partnership exception applies in your state |
| Caregiver benefit while caring for your child under 16 | 75 percent of your benefit, no age requirement | Nothing. Only the child’s own 75 percent is payable |
| $255 lump-sum death payment | Payable to a spouse living in the same household | Not eligible |
| Pension survivor annuity | Federal law requires spousal consent to waive it | No statutory right unless the plan document allows a non-spouse beneficiary |
| Inherited 401(k) or IRA | Can roll the account into their own IRA and defer to their own required beginning date | Ten-year depletion rule, unless the partner is not more than 10 years younger and qualifies as an eligible designated beneficiary |
| Federal estate tax on what you leave them | Unlimited marital deduction. No federal estate tax at any amount | Only the $15,000,000 exemption protects the transfer |
| Inheritance tax in a state that levies one | Exempt in all five states | Top tier: 15 percent in Pennsylvania, 10 percent in Maryland, 15 percent in Nebraska, 15 to 16 percent in New Jersey, 6 to 16 percent in Kentucky |
| Intestate share if you die without a will | Statutory share, plus homestead and elective-share rights in most states | Nothing. The estate passes to children, parents or siblings |
| Group life at work with no beneficiary named | Usually first in the plan’s order of precedence | Usually last, behind children, parents and the estate |
| Timing of the death benefit | Paid directly to the named beneficiary, outside probate | Same, and this is why naming the partner as beneficiary matters more than the ownership question |
Which debts a surviving partner actually owes, and which die with you
Debt is where cohabiting couples get the arithmetic wrong in both directions. The general rule is that a debt is personal. Credit card balances, medical bills, personal loans and federal student loans are discharged at death, and a surviving partner is not personally liable for them unless they signed the note or held the account jointly. The estate pays what it can, and what remains is written off. What a partner does face is a creditor calling on assets that both names sit on, and the practical loss of the household’s second income.
Joint debt is different, and it is the item most couples never quantify. Co-sign a car loan, hold a joint credit card, or sign a joint personal loan and the surviving partner owes the entire balance, not just their share, because joint and several liability means creditors can pursue either borrower for everything. A mortgage works the same way when both names are on the note. Add the funeral, the final medical bills and the cost of settling an estate that has to go through probate because you were not married, and the lump-sum requirement usually lands between $30,000 and $80,000 before a single month of lost income is replaced.
| Obligation | Who pays after your death | Cover it with insurance? |
|---|---|---|
| Individual credit card in your name only | The estate, up to the value of the estate. Never a personal claim against the partner | Only indirectly, by keeping enough cash in the estate to pay it |
| Joint credit card or authorised-user account | The surviving partner, in full, if they are the primary or joint account holder | Yes. Add the balance to the coverage figure |
| Car loan you co-signed or hold jointly | The surviving partner on the note, whether or not they keep the car | Yes, if the vehicle is retained or the loan has negative equity |
| Federal student loans in your name | Discharged at death. No transfer to a partner | No, unless your partner co-signed a private loan |
| Private student loan with a co-signer | The co-signer, unless the lender offers a death discharge | Yes, for the co-signing partner’s exposure |
| Mortgage when one name is on the note | The estate owes it; the partner can be forced to sell or refinance | Yes. This is the single largest lump-sum item for most couples |
| Funeral, cremation and burial | Whoever arranges and signs. Typically $8,000 to $15,000 | Yes |
| Probate and administration costs | The estate, which reduces what reaches your partner | Yes, and avoidable with the right titling and beneficiary forms |
The inheritance tax an unmarried partner can trigger
Five states levy an inheritance tax in 2026: Kentucky, Maryland, Nebraska, New Jersey and Pennsylvania. Iowa completed its repeal for deaths on or after January 1, 2025. In every one of those states, a surviving spouse pays zero. An unmarried partner sits in the most expensive class there is, and the tax follows the state where the estate is settled, so where you live is not what governs.
Pennsylvania is the harshest structure because there is no exemption floor. The rate turns entirely on relationship under 72 P.S. section 9116: 0 percent for a spouse, 4.5 percent for a child or grandchild, 12 percent for a sibling, and 15 percent for everyone else, including friends, cousins and unmarried partners. A partner inheriting $200,000 owes $30,000. Your child inheriting the identical sum owes $9,000. Nebraska taxes non-relatives at 15 percent above a $25,000 exemption, Maryland charges a flat 10 percent on collateral heirs, and New Jersey taxes its Class D beneficiaries at 15 percent on the first $700,000 and 16 percent above, though New Jersey is also the state that treats a registered domestic partner or civil union partner as Class A, which is exempt. Kentucky’s Class C, which now catches friends and unmarried partners, pays 6 to 16 percent above a $500 exemption.
There is one consolation that is easy to misread. The federal estate tax exemption is $15,000,000 per person in 2026, made permanent by the One Big Beautiful Bill Act of 2025, with the top rate at 40 percent and the annual gift tax exclusion at $19,000. At that level almost no couple below eight figures owes federal estate tax, which is why the state inheritance tax, and not the federal estate tax, is the real exposure for a partner inheriting a house and a 401(k). The federal tax does bite in one more place, though: the unlimited marital deduction at Internal Revenue Code section 2056 is available only to a spouse, so a partner’s inheritance never gets that shelter no matter how the will is written.
| State | Rate for a surviving spouse | Rate for an unmarried partner | Exemption |
|---|---|---|---|
| Pennsylvania | 0 percent | 15 percent, from the first dollar | None |
| Maryland | 0 percent | 10 percent flat | None for collateral heirs |
| Nebraska | 0 percent | 15 percent | $25,000 |
| New Jersey | 0 percent (Class A) | 15 percent to $700,000, then 16 percent (Class D). A registered domestic partner is treated as Class A | $500 on small transfers |
| Kentucky | 0 percent | 6 to 16 percent | $500 |
| Every other state | None | None | Not applicable |
How this calculator builds the coverage number
Income replacement is escalated, not multiplied. If your partner needs the household income for 15 more years, replacing $85,000 a year costs far more than $1,275,000, because the same basket of groceries costs about 3 percent more every year. The calculator compounds the income need at 3 percent annually, which is the difference between a defensible number and one that quietly runs out in year nine.

Lump sums are added, never amortised. The mortgage balance, the joint debts, the funeral and the estate settlement costs all land within the first eighteen months. They cannot be paid out of an income stream, so they are stacked on top of the income figure rather than blended into it. This is the structural reason an unmarried partner needs more coverage than the income multiple suggests: none of these obligations are softened by survivor benefits, because there are none.
Only coverage that names your partner counts. Employer group life usually defaults to a plan order of precedence when no beneficiary form exists, and an unmarried partner is typically last, behind a spouse, children, parents and the estate. A $400,000 group certificate naming “my estate” pays your parents and leaves your partner to argue in probate. The calculator asks for coverage that actually names them for that reason, and if you are not certain, treat the field as zero and file a new beneficiary designation this week.
The state inheritance tax is added as a cost of passing assets. It is not a reason to buy more insurance for yourself, but it is a reason to buy more insurance for the survivor: a partner who inherits a $240,000 home in Pennsylvania and has to write a $36,000 check to the state needs that money to come from somewhere. The cleanest source is a life insurance death benefit, which passes by contract rather than by will and is not itself part of the probate estate when a beneficiary is named.
Insurable interest, policy ownership and the beneficiary mistake that costs partners everything
Can you insure a partner you are not married to? In most states, yes, and the safest structure removes the argument before it starts. Insurable interest is judged at the moment the policy is issued, and while spouses are presumed to have it, a non-spouse has to show an economic interest: shared debt, shared housing costs, dependence on the other person’s income. Cohabiting partners who share a mortgage and a budget have that interest, and carriers accept cohabiting couples routinely. The awkward version of the transaction is one partner owning a policy on the other’s life. The clean version is each partner owning a policy on their own life and naming the other as beneficiary, which eliminates both the insurable-interest question and the transfer-for-value trap. Own your own policy and you also control it: you can change the beneficiary, and no one else’s financial problems can put your coverage at risk.
- Own your own policy, name your partner as the beneficiary. Do not have your partner own the policy on your life.
- File a beneficiary designation with your employer plan. A will does not control a group life certificate. The form does.
- Use joint tenancy with right of survivorship, or a transfer-on-death deed, for the home. Otherwise the house passes under intestacy, and your partner is last in line.
- Consider a revocable living trust if you want your partner to have the house and your children not to fight over it. Intentions are not enforceable; documents are.
- Name a trust as a contingent beneficiary if a minor child would otherwise control the payout at 18. A child’s Social Security benefit and a death benefit both need a custodian or a trustee.
- Do not pay premiums on a policy you do not own. Premiums paid on someone else’s policy can be taxable gifts, and the annual exclusion is only $19,000 per recipient in 2026.
- Keep the term as long as the obligation, not as long as the relationship. A 20-year level term at 40 often costs less per month than a 30-year policy at 45 bought later.
Five steps to protect a partner who has no legal safety net
- Run the calculator above with your real budget, then round the coverage number up to the next standard band. The bands your partner can actually be underwritten for are much less important than the fact that the beneficiary form is filed.
- File beneficiary designations on every policy and every retirement account this week. Name your partner by name, not “my estate”, and file a contingent beneficiary as well.
- Fix the title on the home. Joint tenancy with right of survivorship or a transfer-on-death deed keeps the house out of probate, and in an inheritance-tax state it changes who writes the check.
- Get a will that says what an intestate statute will otherwise refuse to say. Guardianship for your children, who gets the house, and who administers the estate all belong in writing.
- Re-run the numbers after every material change: a refinance, a new child, a job change, a move across a state line, or your partner’s income crossing the point where the household still depends on yours.
Watch: financial planning for unmarried couples
Key takeaways
- An unmarried partner receives no Social Security survivor benefit and no caregiver benefit, no matter how long you have lived together. Only the child’s own 75 percent benefit is payable.
- The $255 lump-sum death payment is limited to a surviving spouse or an eligible child. A partner cannot claim it.
- Income replacement for a partner cannot lean on survivor benefits, so the policy has to carry the whole income need plus the mortgage, the joint debts and the final expenses.
- In the five states that levy an inheritance tax, a partner inherits in the most expensive class: 15 percent in Pennsylvania, 10 percent in Maryland, 15 percent in Nebraska, 15 to 16 percent in New Jersey and 6 to 16 percent in Kentucky.
- Each partner should own and be insured under their own policy and name the other as beneficiary. That structure answers the insurable-interest question and keeps control of the contract.
Frequently Asked Questions
Can an unmarried partner receive Social Security survivor benefits?
Generally no. Survivor benefits require a marriage that lasted at least nine months immediately before the death, or one of the narrow exceptions such as the natural parents of a child together. Two routes can change the answer, and both depend on state law: a valid common-law marriage in a state that recognises it, and a registered domestic partnership or civil union where state intestacy law would give the partner a spouse’s share, as California does. Neither is automatic, and both still require the nine-month rule. If you are registered anywhere, ask SSA directly rather than assuming.
Does my partner get anything from Social Security if we have children together?
Your child can receive 75 percent of your benefit until age 18, or 19 if still in secondary school full time, and your partner can be the representative payee who manages that money for the child. What your partner cannot receive is the caregiver benefit, because that payment requires marriage. Social Security reports an average of about $3,898 a month for a widowed parent with two children; the children’s share is what an unmarried partner actually administers.
How much life insurance does an unmarried partner need?
Enough to replace the household income for as long as the survivor needs it, escalated for inflation, plus the mortgage balance, any jointly signed debt, the funeral and estate settlement costs, and in five states the inheritance tax on what the partner inherits. Because no survivor benefit softens any of it, the number typically runs higher than the income multiple a married couple would use. The calculator above produces it directly from your own figures.
Can I take out life insurance on my partner?
In most states yes, if you have an insurable interest, which for a non-spouse means a demonstrable economic interest such as a shared mortgage, shared household expenses or dependence on the other person’s income. Cohabiting couples with intertwined finances generally satisfy that test. The cleaner structure is for each partner to own and be insured under their own policy and name the other as beneficiary, which avoids the ownership question altogether and lets each person keep full control of their own contract.
Will my partner have to pay inheritance tax on what I leave them?
Only if the estate is settled in Kentucky, Maryland, Nebraska, New Jersey or Pennsylvania. In all five, a spouse is exempt and an unmarried partner is taxed in the highest relationship class: 15 percent in Pennsylvania from the first dollar, 10 percent flat in Maryland, 15 percent above a $25,000 exemption in Nebraska, 15 to 16 percent in New Jersey, and 6 to 16 percent in Kentucky. Every other state levies no inheritance tax. A life insurance death benefit paid to a named beneficiary is not part of the probate estate, which is one reason it is the most efficient way to fund the tax.
Does my employer’s group life insurance cover my partner?
Only if you file a beneficiary designation naming them. With no designation, group plans follow an order of precedence that usually puts a spouse first, then children, then parents, then the estate, and an unmarried partner is typically last or excluded entirely. A will does not override the beneficiary form on a group certificate. File the form, and keep a copy of the confirmation.
What happens to my 401(k) if my partner inherits it?
A spouse can roll an inherited 401(k) or IRA into their own account and defer distributions to their own required beginning date. A non-spouse beneficiary cannot, and is generally required to empty the account by December 31 of the tenth year after the death under the SECURE Act, with annual distributions required during the window if you had already begun your own required minimum distributions. One exception matters for partners: a beneficiary who is not more than ten years younger than the account owner is an eligible designated beneficiary and can still take distributions over life expectancy. The toggle in the calculator flags that case.
Is a will enough to leave everything to my partner?
A will is necessary but not sufficient. Life insurance and retirement accounts pass by beneficiary designation, not by will, so an outdated form pays the wrong person no matter what the will says. Real property passes according to its title, which is why joint tenancy with right of survivorship or a transfer-on-death deed keeps a home out of probate. If you die without a will, state intestacy law gives your partner nothing in any state, and the estate goes to children, parents or siblings instead.
