This retirement savings calculator estimates how much your nest egg could grow before retirement. Enter current balance, monthly contributions, expected return, and years to retirement to see projected savings and withdrawal estimates.

Starting earlier often beats contributing more later because compounding has longer to work. Run conservative and optimistic return scenarios.

Employer match is part of your contribution—include matched amounts for an accurate projection.

How to use this tool

Enter current retirement balance, monthly contribution, expected annual return, and years until retirement. Review projected balance at retirement age.

Worked example

Example: $50,000 saved today plus $500/month at 7% for 25 years projects to roughly $550,000 before withdrawals—illustrative only.

When to use this

  • Checking if current savings rate meets retirement goals.
  • Illustrating catch-up contributions in your 40s or 50s.
  • Comparing Roth vs traditional contribution growth conceptually.

Common examples

  • Age 35 with $80,000 saved, $600/month contributions, 7% return to age 65 → projects a balance often in the mid-$800,000s depending on compounding assumptions.
  • Age 50 with $250,000 saved, $1,200/month, 6% to age 67 → models catch-up contributions before Social Security eligibility.
  • Late start: age 45 with $40,000 saved, $900/month, 7% to age 65 → shows how doubling contributions partially offsets a shorter runway.
  • Age 28 with $15,000 saved, $400/month, 7% to age 65 → long runway shows power of early contributions.
  • Age 55 with $400,000 saved, $2,000/month, 5% to age 67 → catch-up planning before Social Security.

How it works

Enter your current age, retirement age, current savings, monthly contribution, and expected annual return. The calculator compounds monthly and assumes contributions are made at the end of each month. Estimated withdrawals use a simple 4% annual rule for illustration only. Inflation, taxes, fees, and contribution changes are not modeled.

Limitations

Projects savings using constant return and contribution assumptions. Market volatility, taxes, and Social Security are simplified.

FAQ

Frequently asked questions

Is this financial advice?

No. Projections are educational estimates, not personalized investment advice.

What return rate should I use?

Many planners use 5–7% for long-term stock-heavy portfolios, but past performance does not guarantee future results.

Does this include Social Security?

No. Add estimated Social Security benefits separately for total retirement income planning.
