Projected balanceContributions

Assumes monthly compounding, contributions at month-end, and a constant return. Taxes, fees, inflation, and market losses are not included.

Use the result as a planning range

Long-term returns are uncertain. Compare a conservative rate with a more optimistic one and review the gap. A future dollar balance also buys less when inflation rises.

Future balance = current savings growth + monthly contribution growth
Does this include Social Security?
No. The result only projects the savings and monthly contribution entered.
Are taxes and fees included?
No. Account fees, fund expenses, and taxes can reduce the result.

How it works

How the Retirement Savings Calculator works

Quick answer: Starting at 35 with $50,000 saved and $750 a month at a 6% return, you would have about $1,054,515 at 65.

Formula

Balance = S(1 + r)^n + C × ((1 + r)^n − 1) ÷ r

S is current savings, C the monthly contribution, r the annual return ÷ 12, and n the months until retirement.

Worked example

Age 35 to 65 (30 years), $50,000 now, $750 a month, 6% a year. Projected balance: $1,054,515. You contribute $320,000; growth adds $734,515.

Assumptions and limits

  • Returns are shown in today's nominal dollars; inflation will reduce purchasing power.
  • Employer matches, taxes, and fees are not modeled separately; include a match in the monthly contribution.

Frequently asked questions

What does the retirement calculator include?

It projects current savings and monthly contributions using a constant assumed return.

Does it include Social Security?

No. Social Security and pension income are not included.

What return should I assume?

Many planners use 5% to 7% for a diversified stock-heavy portfolio over decades. Use a lower rate to be conservative.
