What one more CalSTRS year is worth

Each year you keep working adds a year of service credit. Until you hit 2.4%, it also raises your age factor. The two together add up fast.

California specificsShort answer: a year of work adds a year of service and, until you reach 2.4%, a higher age factor. In the handbook, Faye gets $3,318 a month at 58 and $4,443 if she works to 60. Retiring sooner is on early retirement; buying years instead is on buying service credit. Move your date in the calculator.

Handbook mismatch Check with CalSTRS

The handbook's example says Faye would get $4,443.00 a month at 60. Its own numbers (2.2% x 31 years x $6,500) come to $4,433.00.

We use the formula, so we show $4,433.00.

Questions

How much does one more year add to a CalSTRS pension?

Two things go up: your years of service credit and, until you reach the maximum, your age factor. Faye's handbook example shows how fast that adds up. Use the calculator to see your own numbers.

Why do 25 and 30 years matter?

In CalSTRS 2% at 60, 25 years switches your final compensation to your best 12 months instead of 36, and 30 years adds the career factor (+0.2%). CalSTRS 2% at 62 has neither.
