Project your retirement savings growth and estimate your monthly income in retirement.
Rates as of Q2 2025 (example)
A retirement calculator projects how much your retirement savings could grow by the time you retire, based on your current age, retirement age, current savings, monthly contributions, and an expected rate of return. It also estimates the monthly income that projected balance could support once you stop working, helping you see whether your current savings plan is on track.
This calculator compounds your savings monthly: each month, interest is calculated on your current balance, then your monthly contribution is added before the next month's interest is calculated. This repeats for every month between your current age and your retirement age.
Estimated monthly income: The calculator applies a 4% annual withdrawal rate to your projected savings balance, divided by 12 — a commonly cited guideline (the "4% rule") for how much retirees can withdraw each year without depleting their savings too quickly, though it is an example only and not a guarantee.
Example: Starting at age 30 with $20,000 saved, contributing $500 per month, at a 7% annual return (example rate — actual returns are not guaranteed and vary with market conditions) until age 65, the projected balance reaches a substantial sum, of which a large portion comes from compound growth rather than contributions alone. (Note: all figures in this example are for illustration purposes only and do not represent actual rates or market conditions.)
Most US retirement savings happen through tax-advantaged accounts like 401(k)s, 403(b)s, and IRAs (traditional or Roth), each with its own contribution limits and tax treatment. The 7% default return in this calculator is a commonly cited illustrative example for diversified long-term stock market investing, not a guaranteed or predicted return — actual returns fluctuate and can be negative in some years. This calculator does not account for Social Security benefits, employer matching contributions, taxes on withdrawals, or inflation, all of which affect how much retirement income your savings can realistically provide.
The calculator compounds your current savings and monthly contributions monthly, using your expected annual return divided by 12, from your current age until your retirement age.
The calculator applies a 4% annual withdrawal rate to your projected savings balance to estimate sustainable monthly income in retirement. This is a commonly cited guideline, not a guarantee — actual safe withdrawal rates depend on market conditions, your time horizon, and other factors.
The default 7% is an example only, commonly cited for diversified long-term stock market investing. Actual returns vary significantly year to year and can be negative, so use a conservative estimate for your own planning.
No. This calculator only projects your personal savings and contributions. Social Security benefits, pensions, and other income sources would be in addition to the estimated monthly income shown here.
No. Depending on whether your savings are in traditional (pre-tax) or Roth (after-tax) accounts, withdrawals may be taxed differently. This calculator shows pre-tax projected balances and does not model withdrawal taxes.
No. The projected balance and income are shown in today's dollars without adjusting for inflation, which will reduce the real purchasing power of that income by the time you retire, especially over long time horizons.
