Per stirpes vs per capita beneficiary designations

Per stirpes sends a deceased beneficiary's share to their children; per capita splits it among survivors. A worked example and what to check on your form.

4LifeInsurance · Published October 4, 2026

With per stirpes ("by branch"), if a beneficiary dies before you, their share passes to their own children. With per capita ("by head"), the share is redistributed among the beneficiaries who are still alive. The choice only matters when someone on a multi-person designation dies before the insured, and it can change who gets hundreds of thousands of dollars. The per stirpes vs per capita calculator runs your numbers.

The two rules in plain terms

per stirpes treats each named beneficiary as the head of a family branch. If that person is gone, their branch inherits their share, split equally among their living children, and if a child is also gone, among that child's children, and so on down.

per capita has no branches. The dead beneficiary's share is divided among the other named beneficiaries (or, in some versions, among all living members of the class). The deceased person's children receive nothing unless they were themselves named.

Per stirpes Per capita
Deceased beneficiary's share goes to Their descendants The surviving named beneficiaries
Keeps shares fixed by branch Yes No
Grandchildren benefit Yes, if their parent died first Only if they are named
Best when You want each branch to receive an equal portion You want to benefit those named, or avoid minors receiving money

A hypothetical example

Say a policy pays $600,000 to three adult children, Ava, Ben and Cara, one-third each. Ben dies before the insured and leaves two children, Dan and Eve.

  • Per stirpes: Ava gets $200,000, Cara gets $200,000, and Ben's $200,000 is split between Dan and Eve: $100,000 each.
  • Per capita: Ben's $200,000 is divided between the two survivors, so Ava and Cara each get $300,000. Dan and Eve get nothing.

Neither result is "right." Per stirpes keeps each branch whole. Per capita favors the survivors, which may be intended if the grandchildren are well provided for or if you do not want a minor to receive money.

If Dan or Eve are minors, per stirpes means the insurer must pay through a guardian, custodian or trust; see naming a minor child as life insurance beneficiary.

Why the terms are confusing

  • "Per capita" has two meanings. Under the classic version, the shares are redistributed among survivors as above. A variant sometimes called "per capita at each generation" or "per capita with representation" first divides the estate at the level of the children, then pools the shares of deceased children and divides them equally among the next generation. State law and the contract text control, so read the definition on your form rather than assuming.
  • Not every insurer uses these words. Some forms say "to my surviving children," "to the survivors," or "to the descendants of any deceased beneficiary." The first two work like per capita; the third works like per stirpes. Wording differences can matter, so confirm with the insurer how a phrase will be applied.
  • Wills and policies are separate. An instruction in your will does not control a life insurance designation. See life insurance and your will.

When each fits

Per stirpes suits you if:

  • You have several children and want each family branch to be treated equally.
  • You want grandchildren protected if their parent dies first.
  • You are willing to pay a minor through a trust or custodian.

Per capita suits you if:

  • You want only the people you named to benefit.
  • Surviving siblings are expected to look after the nieces and nephews.
  • You want to keep the plan simple and avoid payments to minors.

Per stirpes is the more common default for estate planning, but it can leave the money split among many small shares and may add complexity when minors are involved. If you do not tick either option, the insurer's default or the policy terms apply, which is why this choice should not be left blank. If a beneficiary dies and there is nothing on the form, see what happens if your beneficiary dies before you.

What it means for claims

The insurer needs proof of who the surviving beneficiaries and descendants are. With per stirpes, a claim can require death certificates for the deceased beneficiary and birth or family records for their children, which can slow the payout. A clear designation with full names and dates of birth for each person helps, and naming contingent beneficiaries individually avoids the question altogether.

How to set it up

  1. List your beneficiaries and their shares for each level (primary and contingent).
  2. Decide, for each level, whether a deceased beneficiary's share should go to their descendants or to the survivors.
  3. Find the option on the insurer's form or in its online portal. Some insurers apply a single rule to the whole designation.
  4. If the form has no per stirpes option, ask the insurer to explain how it handles a deceased beneficiary, or name contingent beneficiaries explicitly.
  5. Use a trust for any descendants who could be minors or who may need protection.
  6. Run a scenario in the per stirpes vs per capita calculator and keep the insurer's confirmation. See how to change your life insurance beneficiary.

Where the rules vary

Which meaning applies when a form is unclear, and what happens to a share when no instruction exists, depends on the contract and on state law. Employer coverage follows the plan documents. See primary vs contingent beneficiaries and Employer life insurance, ERISA and beneficiary disputes. For questions about a specific policy, ask the insurer, and for disputes, an estate attorney.

Key takeaways

  • Per stirpes passes a deceased beneficiary's share to their descendants; per capita divides it among surviving beneficiaries.
  • The choice only applies when a beneficiary dies before the insured, but it can redirect large sums.
  • Read the insurer's own definition, because "per capita" has more than one meaning.
  • Pair per stirpes with a trust or custodian if grandchildren could be minors.
  • Run the numbers in the per stirpes vs per capita calculator before you submit the form.

Per stirpes A way of splitting proceeds by family branch, so if a beneficiary dies before the insured, that person's share passes to their own descendants. Per capita A way of dividing proceeds equally among the named beneficiaries still living at the insured's death, so a deceased one's share goes to the survivors. Beneficiary The person, trust, charity or estate named to receive a life insurance death benefit or an annuity's remaining value when the insured or owner dies. Contingent beneficiary The person or entity who receives life insurance proceeds only if every primary beneficiary has died or cannot accept the payment.
