The retirement-age solver
Last updated September 20, 2026
"Help me find it" works backwards from the odds you want: it sweeps your retirement age and returns the earliest one that still clears your chosen chance of success.
Rather than you guessing an age and reading the result, you name the confidence you want and it finds the age. It runs the full simulation at each candidate age, so the answer accounts for everything you have entered.
It can come back with no answer. If nothing up to the ages it searches reaches your threshold, it says so rather than returning the closest miss and letting you read it as a pass.
For couples it sweeps the primary person's age only. A joint solver — moving both retirement dates together — is not built.
