How it works
Future value = P(1+r)^n + PMT · ((1+r)^n − 1) / r, where P is the current balance, PMT is the monthly contribution, r is the monthly return rate, and n is the number of months until retirement.
Complete guide
Retirement planning rewards starting early. Thanks to compound returns, a 25-year-old saving $300/month at 7% annual return ends up with more than a 35-year-old saving $600/month for the same retirement age.
Enter your current age, target retirement age, what you've already saved, how much you contribute each month, and the average annual return you expect (historically, a diversified stock portfolio has returned around 7% after inflation).
The result is a rough projection — actual markets are volatile, fees and taxes reduce returns, and inflation erodes purchasing power. Treat the number as a planning compass, not a guarantee.
Frequently asked questions
- What return rate should I use?
- A common assumption is 6–8% annual return for a diversified equity-heavy portfolio. Use a lower figure (3–5%) if you're closer to retirement and holding more bonds.
- Should I subtract inflation?
- Yes if you want the result in today's purchasing power. Subtract roughly 2–3% from your expected nominal return to get a real return.
- How much do I need to retire?
- A common rule of thumb is 25× your desired annual spending (the 4% rule), but it varies with lifestyle, health, location, and social security or pension income.
