Calculators

Estimate Social Security claiming tradeoffs, safe spending, required withdrawals, and how long savings may last. Change inputs and compare outcomes side by side.

Educational estimates only. Not individualized financial, tax, or legal advice.

Social Security claiming calculator

Compare monthly benefits at different claiming ages using a simplified FRA adjustment model. Useful for education, not a benefit quote.

Bars show relative monthly benefit from age 62 to 70 under a simplified ruleset.

Safe spending rate calculator

Translate portfolio size and a spending rate into monthly and annual income from savings. Add Social Security or pension as an income floor.

3.5% spending
4.0% spending
4.5% spending
5.0% spending

Required withdrawal estimator

Estimate a first-year required minimum distribution (RMD) using a simplified Uniform Lifetime-style divisor. For education only. Official IRS tables may differ.

Divisor used is an approximation that declines with age. Always verify against current IRS publications.

How long will savings last

Project portfolio longevity under a fixed monthly spend, assumed return, and inflation. Simple model for scenario testing.

Chart samples remaining balance every few years until depletion or year 40.
