How the calculation works

Required capital is the present value of monthly withdrawals. Savings grow at a real return; monthly contributions cover the gap at retirement.

Inputs

  • Current age
  • Retirement age
  • Years in retirement
  • Current savings
  • Monthly retirement spending
  • Other monthly retirement income
  • Real annual return, %

Calculation details

All amounts are in today’s money. Enter a return after inflation, taxes, and fees.

Enter public pension income separately. A constant return does not model market volatility, longevity risk, or guarantee income.
