Free Retirement Calculator - Plan Your Savings
Plan your retirement savings.
Formula & Methodology
The Retirement Calculator projects your nest egg by compounding your current savings and adding the future value of your ongoing contributions, both growing at the return rate you enter. It then multiplies the resulting balance by a safe withdrawal rate to estimate the annual income that nest egg could support.
- FV = P(1 + r)^t + PMT × [((1 + r)^t − 1) / r]
- Annual Withdrawal = Nest Egg × Safe Withdrawal Rate
Worked Example
Using the Retirement Calculator: apply the formula above to your input values. For instance, FV = P(1 + r)^t + PMT × [((1 + r)^t − 1) / r], then Annual Withdrawal = Nest Egg × Safe Withdrawal Rate. The tool performs each step instantly and shows the result.
Frequently Asked Questions
How much do I need to retire?
It projects the savings required to fund your retirement spending, factoring in your contributions, returns and time horizon.
What is a safe withdrawal rate?
A common guideline is withdrawing about 4% of your portfolio in the first year, then adjusting for inflation.
Does starting early really matter?
Enormously. Because of compounding, saving early can require far smaller contributions than starting later for the same goal.
