How this is calculated

Each year until retirement: balance = balance × (1 + growth) + contribution, with contributions added at year end. Today’s-dollar value = balance ÷ (1 + inflation)^years.

Income uses a level real withdrawal over your chosen years, paid at year end, with real return = (1 + growth) ÷ (1 + inflation) − 1 = 3.41%. Payment = savings × rate ÷ (1 − (1 + rate)^−years). If the real rate is zero, payment = savings ÷ years.

Assumptions: constant returns and inflation, no taxes, no fees, no Social Security or pensions, contributions constant in nominal dollars, savings reach zero at the end of the period.

Common questions

What does this retirement income calculator estimate?

It estimates future savings from a starting balance, contributions, and assumed growth, then calculates level inflation-adjusted income over an assumed retirement period. It is an educational illustration, not a safe-withdrawal recommendation or guarantee.

What is missing from this retirement income estimate?

The estimate simplifies investment returns and inflation. It does not model your full tax situation, fees, changing markets, benefit choices, health costs, or personal circumstances. The page shows its formulas and assumptions so you can understand the limits.
