Calculator use

Best for

  • Quick savings duration from starting savings, monthly withdrawal and monthly deposits.
  • Personal finance scenarios before changing a budget, loan, savings goal, or purchase plan.
  • Monthly cash flow, affordability, debt payoff, or future-value estimates.
  • Assumption checks before talking with a lender, tax preparer, employer, or financial professional.

Before relying on it

Check first

  • Entering starting savings, monthly withdrawal and monthly deposits from different time periods or scenarios.
  • Mixing gross income, take-home income, one-time costs, and monthly costs in the same comparison.
  • Forgetting taxes, fees, insurance, irregular bills, or minimum payments when using an estimate.
  • Treating a planning estimate as a quote, tax filing result, approval decision, or guaranteed return.

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.
