Retirement Calculators

Choose a tool for your next planning question

Each calculator uses a simplified model. Start with the question you need to answer, enter clearly labeled assumptions, and read the limitations beside the result.

Retirement Savings Calculator

Project how a starting balance and monthly contributions might grow. Compare returns and inflation without treating a projection as a promise.

Retirement Income Calculator

Estimate a level monthly portfolio withdrawal over a chosen retirement period, expressed in purchasing power at the start of retirement.

FIRE Calculator

Estimate a financial-independence target and the time to reach it under a simplified constant-return savings scenario.

401(k) Employer Match Calculator

Estimate a simple employer match using your plan’s match percentage and eligible-pay limit. This tool supports one matching tier.

Use the combined retirement plan calculator

The homepage calculator compares projected savings with an illustrative spending-based target. It is useful for a first overview before exploring contributions, withdrawals, or inflation separately.

Keep your inputs consistent

Use the same dollar basis and return convention when comparing results. Savings tools divide a nominal annual rate by 12; the income, withdrawal, and FIRE tools convert effective annual rates to effective monthly rates. Read the methodology for the difference.

All tools are educational. They do not connect to your accounts or predict market returns.
