This is a planning estimate. Returns are assumed steady, but real savings and investments can fluctuate.

  1. Enter your current savings balance.
  2. Enter the amount you expect to withdraw each month.

Calculator use

Best for

  • Use this savings withdrawal calculator to estimate how long a savings balance can support monthly withdrawals after deposits and return assumptions.
  • Estimating savings, budget, debt, tax, interest, retirement, or net-worth scenarios before changing a money plan.
  • Comparing monthly contributions, withdrawals, balances, interest rates, payoff order, or tax assumptions with the math visible.
  • Preparing a planning number before checking account statements, tax rules, benefits, or professional advice.

Before relying on it

Check first

  • Treating an estimate as tax filing advice, investment advice, guaranteed return, or an official account balance.
  • Leaving out fees, taxes, inflation, irregular bills, employer benefits, penalties, changing rates, or timing differences.
  • Comparing scenarios with different time horizons, compounding assumptions, or gross versus after-tax amounts.

FAQ

Common questions

How do I calculate how long savings will last?

Subtract net monthly withdrawals from the balance each month, add any return, and repeat until the balance reaches zero.

Does this account for inflation?

No. It keeps withdrawals fixed. For long plans, inflation can make future spending higher.

Can savings last indefinitely?

In this model, savings can last indefinitely if deposits and returns cover the withdrawal. Real-world results can vary.

Is this a final financial decision?

No. Use it for planning and comparison. Real decisions can change after exact rates, balances, fees, taxes, account terms, timing, and personal details are verified.

Why do finance calculators show assumptions?

Small changes in rates, payment timing, taxes, fees, balances, or income can materially change the result, so the assumptions need to stay visible.
