Why this page exists

Retirement planning becomes more useful when the target feels like a real projection instead of a vague hope. This calculator helps you estimate how current retirement savings and ongoing contributions may grow over the years ahead under a simple return assumption.

Retirement savings calculator

Estimate how retirement savings may grow from your current balance, monthly contributions, expected return, and time horizon.

Result

$1,013,207

Projected retirement balance based on the current savings, monthly contributions, expected return, and time horizon entered.

Projected retirement balance$1,013,207

Total contributions$280,000

Estimated investment growth$733,207

Time horizon25 years

At 7.00%, the estimated growth comes from both the current balance and $650 added each month.
The estimate adds roughly $733,207 in growth beyond the money contributed.
Long timelines are powerful because each extra year gives compounding more room to work, which is why even modest monthly contributions can add up.

This is a planning calculator, not investment advice. Real markets, taxes, fees, and withdrawal needs can change the outcome materially.

How it works

What the calculator is doing

Enter your current retirement balance, monthly contribution, expected annual return, and the number of years until retirement.

The calculator projects the balance forward month by month using the return assumption you entered.

Use the projected balance, total contributions, and estimated investment growth to see what part of the result comes from saving versus market growth.

Understanding your result

A retirement projection is a planning tool, not a promise. The best use of the result is often comparing different contribution levels or timelines so the next savings decision becomes easier to make.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Check whether a higher monthly contribution changes the picture

Increase the monthly deposit to see how much more flexibility or balance growth it may create over a long timeline.

Compare retiring at two different ages

Change the years until retirement to see how much one more stretch of saving and compounding may add.

Use a more conservative expected return

Test a lower return rate if you want a projection that feels more cautious and planning-focused.

FAQ

Common questions

Should I use my current account balance or all retirement accounts combined?

Use the amount you want the projection to represent. Many people enter the total across all retirement accounts if they want one cleaner estimate.

Does this include employer matching automatically?

No. If you want matching included, add it into the monthly contribution figure before running the estimate.

Why is the growth amount so large over long timelines?

Long time horizons give compounding more years to build on itself, so investment growth can eventually overtake the raw dollars contributed.
