This calculator is provided as a retirement planning tool to help you estimate your future retirement benefit. Calculations are estimates only.

If you return to CalSTRS-covered employment, or if you are a member of another California public retirement system, you may restore past Defined Benefit refunded service credit by redepositing your refunded contributions plus interest.

Estimate the number of installment payments or the installment amount needed to finance your purchase of permissive service credit or a redeposit.

Use this calculator to estimate the cost to purchase permissive service credit.
