FAQ
How does a pension change my FIRE number?
Subtract the pension from your annual spending first, then multiply the remainder by 25. The smaller gap is all your portfolio must support.
What about Social Security?
Treat it like a pension: enter the annual amount you expect and it reduces the invested balance you need. Estimates vary, so run a few scenarios.
