The retirement-age solver
Last updated November 3, 2026
"Help me find it" works back from the odds you want. It tries one retirement age after another and returns the earliest one that still clears your chosen chance of success.
You name the chance of success you want, and it finds the age. It runs the full simulation at each age it tries, so the answer accounts for everything you've entered.
If no age reaches the chance you picked, it says so, instead of showing you the closest miss.
For couples, it moves only the primary person's age. It doesn't move both retirement dates together.
