Project your retirement nest egg. Enter your age, savings, monthly contributions and expected return to see your projected balance at retirement.

What is the Retirement Calculator?

A retirement calculator projects the future value of your nest egg: current savings compounding over the years until retirement, plus the future value of every monthly contribution. The yearly table shows the balance climbing — slowly at first, then steeply as compounding takes over — which is the strongest visual argument for starting early that personal finance has.

This free retirement calculator uses a constant expected return, so treat the projection as a planning scenario, not a promise. Markets do not deliver 7% smoothly; they deliver volatility around a long-run average. Run optimistic and pessimistic rates to see your range of outcomes, and remember the output is pre-tax and pre-inflation unless you adjust the rate down.

The most actionable insight is usually the contribution lever. Because contributions compound for decades, raising your monthly savings by $200 in your thirties can add six figures to the final balance — far more than the same increase made in your fifties. Small changes now beat heroic catch-ups later.

One last reality check: health and longevity are the wild cards no calculator models. Planning for a 30-year retirement when you might need 40 argues for slightly more saving, not less — and for investments that outpace inflation across decades, since cash quietly loses the long game.

How to use the Retirement Calculator

  1. Enter your current age and your target retirement age.
  2. Enter your current retirement savings across all accounts.
  3. Enter what you contribute monthly, including any employer match.
  4. Enter a realistic long-term annual return (6–8% is common for stock-heavy portfolios).
  5. Click Calculate and study the yearly table and the contributions-vs-growth split.

Retirement Calculator use cases

Are you on track?

Compare your projected balance against rules of thumb — e.g., 1x salary by 30, 3x by 40, 6x by 50, 8–10x by 67. A shortfall discovered at 35 is fixable with modest contribution increases; discovered at 55, it demands drastic action.

Contribution tuning

Test raising contributions by 1–2% of salary and watch the final balance jump. The table quantifies exactly what each extra dollar per month buys you at retirement, which makes increasing your 401(k) deferral an easy decision.

Early retirement math

FIRE planners can model retiring at 50 or 55 instead of 65. The calculator shows the double hit clearly: fewer compounding years plus more retirement years to fund — and exactly how much extra saving bridges the gap.

Catch-up planning

Starting late? Model aggressive contributions plus catch-up limits (extra 401(k)/IRA allowances after 50) to see what is still achievable. The numbers are honest about the cost of delay — and about the power of a focused final decade.

Tips

  • Count employer matches as contributions — it is free money.
  • Use 5–7% returns for planning; optimism is not a strategy.
  • Revisit yearly; life changes faster than projections.
  • Projections are for informational purposes only, not financial advice.

Frequently asked questions

How much do I need to retire?
The classic 4% rule suggests 25x your annual spending — $1M supports ~$40,000/year. Fidelity's benchmarks suggest 10x final salary by 67. Your real number depends on spending, pensions, Social Security and longevity. Use this calculator to project savings, then compare against 25x your expected annual expenses.
What rate of return should I use?
For long horizons, 6–8% nominal for stock-heavy portfolios is the conventional planning range (US stocks averaged ~10% nominal historically, ~7% after inflation). Use the lower end for conservatism, and consider subtracting 2–3% for inflation to think in today's dollars. Always run a pessimistic scenario too.
How much should I contribute monthly?
The oft-cited 15% of gross income (including employer match) is a solid baseline starting in your twenties. Starting later requires more — 20–25% in your forties is common advice. Enter your current contribution above and raise it until the projected balance meets your target; the table shows the payoff per extra dollar.
Does this include inflation?
No — the projection is in nominal future dollars. To think in today's purchasing power, reduce the return by expected inflation (~2–3%). A $1.5M projection at 7% nominal over 30 years is roughly $830,000 in today's dollars at 2% inflation. Planning in real terms keeps lifestyle expectations honest.
What about taxes on my retirement savings?
The calculator shows pre-tax balances. Traditional 401(k)/IRA withdrawals are taxed as income; Roth withdrawals are tax-free in retirement. A $1M traditional balance might net ~$750,000+ after taxes depending on brackets. Model your expected withdrawal tax rate separately for a true spendable figure.
I am starting late — can I still catch up?
Yes, with focus. Maximize contributions, use catch-up provisions after 50 ($7,500 extra for 401(k)s in recent years), delay Social Security to 70 for larger benefits, and consider working a few extra years — each additional year both adds contributions and shrinks the funded period. The calculator quantifies exactly what each step buys.
Should I pay off debt or save for retirement first?
Capture any employer 401(k) match first (instant 50–100% return), then kill high-interest debt above ~7–8%, then max retirement savings. Low-interest debt like a 3% mortgage can run in parallel with investing. The match-first rule is nearly universal because no market return reliably beats it.
