How to Use the Retirement Calculator

Enter your current age, target retirement age, current retirement savings, monthly contribution (including any employer match), and an expected annual return — the calculator projects your balance at retirement and, if you enter a target annual spending amount, shows whether that projected balance is on track to support it.

The Retirement Calculator projects your savings forward and compares it against a target — here's what to enter for a realistic result.

Entering current savings and contributions

Include your current balance across all retirement accounts, your monthly contribution amount, and any employer match separately if the calculator supports it — leaving out the match understates the real growth trajectory significantly, since it's effectively free additional contribution.

Setting a realistic target and return rate

Enter an expected annual retirement spending figure (or let the calculator estimate one from current income) and a reasonably conservative return rate — using an overly optimistic rate makes the projection look more comfortable than it may realistically be.

Frequently asked questions

What if I don't know my expected retirement spending?

A common starting estimate is 70–80% of your pre-retirement income, adjusted based on whether your mortgage will be paid off and how your other expenses are expected to change — treat it as a starting point to refine over time, not a fixed number.

Does the calculator account for Social Security?

Check whether the specific tool includes a field for expected outside income like Social Security or a pension — if not, manually subtracting expected annual Social Security income from your target spending before entering it gives a more accurate personal-savings target.
