    A FIRE calculator that verifies or determines your retirement number▲5

    Most retirement calculators either oversimplify things or ask you to link your accounts so they can make money off your data. I wanted something that actually helped me see if I was on track without handing over a bank login, so I built RetireNumber. It's a privacy-first retirement planner. You type in your own numbers. No account linking, no selling your data, no VC. Just me and a subscription. The engine does real math: Monte Carlo with 1,000 runs, historical backtesting to 1928 using Shiller's Yale data, tax-aware withdrawal strategies, and scenario comparison so you can try different…

    The Tortoise – a sophisticated retirement calculator▲6

    Hi HN! I've been working on this calculator for some time now. It started off as a tool to help me do some retirement planning and I think it could be broadly useful to others as well.
