How It Works
This calculator uses the future value formula for both a lump sum and an annuity (series of regular contributions). Your current savings grow with compound interest: FV = PV × (1 + r)^n. Your monthly contributions grow as a future value of an annuity: FV = PMT × ((1 + r)^n − 1) / r. The sum of both gives your projected retirement balance. The power of compound growth means starting early—even with smaller contributions—can make a dramatic difference in your final balance.
Frequently Asked Questions
What annual return rate should I use?
A common assumption for a diversified stock portfolio is 7% after inflation (10% nominal). For more conservative investments like bonds, 3–5% may be more appropriate. Use a lower rate for a more conservative estimate.
How much should I save for retirement?
A common guideline is to save 10–15% of your gross income for retirement. The 4% rule suggests you need about 25 times your desired annual retirement spending saved. For example, if you need $50,000/year in retirement, aim for $1.25 million.
Does this account for inflation?
Not directly. You can adjust for inflation by using a "real" return rate (nominal return minus expected inflation). For example, if you expect 8% returns and 3% inflation, use 5% for an inflation-adjusted projection.
