The 4% rule, simplified

The safe withdrawal rate (4% rule) suggests that if your retirement portfolio equals 25× your annual spending need, you can withdraw 4% per year (adjusted for inflation) and have a high probability of not running out of money over 30 years.

Use this calculator to project your future portfolio value — then divide by 25 to estimate the annual income it can support.

Maximize cumulative interest in retirement accounts

  • Start early. A 25-year-old saving $400/month at 7% retires with more than a 35-year-old saving $800/month — the extra decade of compounding wins.
  • Use tax-advantaged accounts. 401(k), IRA, Roth IRA, ISA, or pension accounts shelter cumulative interest from tax drag.
  • Capture employer match. It's an instant 50–100% return on every matched dollar.
  • Enable step-ups. Increasing your contribution 3–5% yearly mirrors raises and dramatically grows the final balance.

Retirement Calculator — FAQ

How much do I need to retire?
A common rule is the 4% rule: you can safely withdraw 4% of your portfolio in year one and adjust for inflation thereafter. So if you need $60,000/year in retirement, target around $1.5M. Always plan for healthcare and longevity buffers.
What annual return should I assume for retirement?
A balanced portfolio typically averages 6–8% nominal historically. Many planners use 7% nominal or 4–5% real (after inflation). Run multiple scenarios on our comparison page to be safe.
How does inflation affect retirement?
Inflation roughly halves purchasing power every 25–30 years at 2.5% inflation. Always view results in real (inflation-adjusted) dollars when planning long-term — enable inflation in advanced options.
Should I include employer 401(k) match?
Yes — employer match is essentially a guaranteed 100% return on the matched amount. Add it to your monthly contribution input. For example, if you contribute $500/month and your employer matches $250, enter $750.
