Bottom line
A CalSTRS option trades part of the member’s monthly retirement benefit for lifetime income to an option beneficiary. The option type, ages, and timing of the election determine the reduction.Key facts
- CalSTRS offers 100%, 75%, 50%, and Compound beneficiary options for its Defined Benefit retirement benefit.
- Electing an option reduces the member’s monthly benefit through an option factor based on the option and the ages involved.
- The one-time death-benefit recipient is a separate designation from an option beneficiary who may receive lifetime monthly payments.
Member-Only Benefit versus an option beneficiary
CalSTRS starts the choice with the Member-Only Benefit, the highest monthly retirement amount payable for the member’s lifetime under the Defined Benefit formula. A member who wants a lifetime monthly payment to continue to another person after death can elect a beneficiary option instead. That election produces a Modified Benefit, which is lower while the member is alive because the payment is priced to cover two lifetimes or, under the Compound Option, one or more beneficiary allocations.
This option beneficiary is different from the one-time death-benefit recipient. CalSTRS describes the one-time recipient as the person or people who receive a lump-sum death payment when applicable. An option beneficiary, by contrast, is selected to receive ongoing lifetime monthly payments under the retirement option. The same person may hold both roles, but the designations are separate.
What 100%, 75%, 50%, and Compound mean
CalSTRS offers three single-beneficiary percentages plus the Compound Option. Under the 100% Beneficiary Option, the option beneficiary receives the same Modified Benefit amount after the member dies. Under the 75% option, the beneficiary receives three-quarters of the member’s Modified Benefit. Under the 50% option, the beneficiary receives one-half. If that option beneficiary dies before the member, CalSTRS says the member’s payment rises to the Member-Only Benefit level for these options.
The Compound Option can provide for more than one option beneficiary or preserve part of the member’s benefit as Member-Only while allocating another part to a beneficiary option. The exact payment reduction depends on the allocations and the people involved. Because the 100%, 75%, and 50% labels describe the survivor percentage of the Modified Benefit, they should not be read as the percentage reduction taken from the member’s original benefit.
| Election | Payment after member death | If the option beneficiary dies first |
|---|---|---|
| 100% Beneficiary Option | 100% of the Modified Benefit for that beneficiary | Member benefit rises to Member-Only level |
| 75% Beneficiary Option | 75% of the Modified Benefit | Member benefit rises to Member-Only level |
| 50% Beneficiary Option | 50% of the Modified Benefit | Member benefit rises to Member-Only level |
| Compound Option | Allocated lifetime benefits to one or more beneficiaries | Result depends on the allocations and option terms |
Use the option factor, not a rough percentage guess
CalSTRS calculates the Modified Benefit by multiplying the Member-Only Benefit by an option factor. The factor is based on the option chosen and the ages of the member and option beneficiary on the relevant election or retirement date. For a preretirement election, CalSTRS says the member receives the higher option factor available on the election date or retirement date.
Before deciding, compare a current estimate for each option against the Member-Only amount and the survivor income it would create. CalSTRS provides an online retirement calculator for common scenarios and can produce individualized estimates for situations the calculator does not cover. Treat the result as an estimate until CalSTRS establishes the benefit. The official retirement application and system calculation control, so do not carry an old factor table forward if the retirement or beneficiary information has changed.
Electing before retirement can lock in a useful factor
A vested member who is eligible to retire can elect an option before filing for retirement. CalSTRS says the election can provide a lifetime monthly benefit to the named option beneficiary if the member dies before retirement. The survivor amount is based on the reduced benefit that would have been payable if retirement had occurred on the date of death.
CalSTRS also notes a potential factor advantage: when a preretirement option is elected, the option factor used at retirement will be the higher factor available on the election date or on the retirement date. That does not mean a preretirement election is automatically better for every household, because the member is committing to a survivor design and future benefit reduction.
Age rules can limit a nonspouse beneficiary election
Federal age restrictions can narrow the available option when the option beneficiary is not a spouse or former spouse. CalSTRS states that under the 75% Beneficiary Option, a nonspouse option beneficiary cannot be more than exactly 19 years younger than the member. For Compound elections, the same 19-year limit applies to a nonspouse beneficiary receiving the 75% option, and a 10-year age difference limit applies when the allocated option is the 100% Beneficiary Option.
Check these age limits before relying on a survivor estimate for a child, sibling, friend, or other nonspouse beneficiary. They are eligibility limits on the option design, not merely factors that increase the reduction. Use verified birth dates and request a CalSTRS estimate for any Compound Option involving several people or allocations.
| Situation | Current CalSTRS age restriction to check | Why it matters |
|---|---|---|
| 75% option with nonspouse beneficiary | Beneficiary cannot be more than exactly 19 years younger | The election may be unavailable if the age gap is larger |
| Compound allocation using 75% option for nonspouse | Same 19-year limit | Each allocation must satisfy the applicable rule |
| Compound allocation using 100% option for nonspouse | Beneficiary cannot be more than exactly 10 years younger | A larger age gap can make that allocation unavailable |
Changing an option after retirement is limited
CalSTRS allows a short correction window after retirement. Its current postretirement FAQ says an applicable option change or cancellation must be received no later than 30 days from the date the first benefit payment was issued to receive the stated retroactive effective treatment. After that window, changes are restricted to specific events, including death of the option beneficiary, divorce from an option-beneficiary spouse, replacing a nonspouse beneficiary with a spouse, or adding a new spouse after retirement when the member had retired without an option.
For a permitted later change to a new option beneficiary, CalSTRS says the election generally becomes effective six months after it receives the new designation, provided the conditions are met. The member’s benefit is then recalculated based on the member’s age and the new beneficiary’s age. Divorce has additional document requirements, and a court order may require the former spouse to remain an option beneficiary for a community-property share.
Before you make a decision
- Compare the current Member-Only estimate with 100%, 75%, 50%, and any Compound option under consideration.
- Verify each proposed option beneficiary’s date of birth before relying on an option factor.
- Check federal nonspouse age restrictions when the beneficiary is not a current or former spouse.
- Review whether a preretirement option election fits the desired survivor protection before filing it.
- Confirm the one-time death-benefit recipient separately from the option beneficiary.
- Treat postretirement option changes as limited and verify any permitted change directly with CalSTRS.
Frequently asked questions
What is the difference between CalSTRS Member-Only and 100% beneficiary options?
The Member-Only Benefit is the highest monthly Defined Benefit payable for the member’s lifetime and does not provide a continuing option payment after death. The 100% Beneficiary Option reduces the member’s payment to a Modified Benefit and continues that same Modified Benefit amount to the option beneficiary for life.
Does the CalSTRS 75% option reduce my pension by 75%?
No. The 75% label describes what the option beneficiary receives after the member dies: 75% of the member’s Modified Benefit. The member’s own reduction is determined by an option factor based on the option and the ages involved. Request a current CalSTRS estimate for the actual amount.
Can I name more than one CalSTRS option beneficiary?
Yes, the Compound Option can provide lifetime benefits to more than one option beneficiary and can also leave part of the pension as Member-Only. The exact allocation and reduction depend on the election. Confirm current age restrictions and request a CalSTRS estimate for the proposed beneficiary mix.
Can I change my CalSTRS option beneficiary after retirement?
Only in limited circumstances after the initial correction window. CalSTRS lists events such as the beneficiary’s death, divorce from an option-beneficiary spouse, naming a spouse in place of a nonspouse, or certain marriages after retirement. The benefit is recalculated when a permitted new beneficiary is elected.
Is my CalSTRS one-time death-benefit recipient the same as my option beneficiary?
No. The one-time death-benefit recipient receives a lump-sum death payment when applicable. An option beneficiary can receive lifetime monthly payments under the retirement option. The same person may be named for both roles, but the designations and benefit mechanics are separate.
