All information calculated using this website is for estimation purposes only. This estimate of your purchase of additional service credit costs was calculated using assumptions based on the information you provided. It is your responsibility to ensure that this information is correct. This estimate is not binding upon you or CalSTRS. If a conflict arises between information provided and the law, the law takes precedence.

Statutory changes are made from time to time that affect CalSTRS benefits and that may affect any decisions you make in relation to those benefits. These changes are made by the California Legislature and the Governor. Although CalSTRS makes every effort to keep its members informed about changes in its benefit structure, it cannot safely predict what the Legislature and Governor may do that might be of interest to you. For this reason, you should keep yourself informed about possible benefit changes by consulting this website, CalSTRS Member Services at 800-228-5453, your union representative (if applicable), your legislative representative, or any other source that you believe may be helpful to you before you make any final decision. You are ultimately responsible for any decision you make in regard to your CalSTRS benefits.

To obtain actual costs to purchase additional service credit, you must submit the necessary form to request a billing statement.

Please, do not send any payments based on these calculations. Any payments received by CalSTRS without an official billing and an established receivable account, will result in monies returned to sender.
