Project how much you could have saved by retirement based on your current savings, monthly contributions, and expected investment return.
Enter your current age, the age you plan to retire, how much you already have saved, how much you contribute each month, and the annual return you expect on your investments. Click "Calculate Savings" to project your balance at retirement.
The calculator uses the future value of a lump sum plus a monthly annuity: FV = P(1+r)^n + C × [((1+r)^n - 1) / r], where P is your current savings, C is your monthly contribution, r is the monthly return rate (annual rate divided by 12), and n is the total number of months until retirement.
Starting at age 30 with $10,000 saved, contributing $300 a month, and earning 7% annually until age 65 (35 years) grows to an estimated balance of roughly $560,000, of which about $136,000 came directly from contributions and the rest from compound growth.
What return rate should I use? A diversified stock portfolio has historically averaged around 7-10% annually before inflation, but future results are never guaranteed, so consider testing a few conservative scenarios.
Does this account for inflation? No, this is a nominal projection. To estimate purchasing power, you can rerun the calculator using a lower "real" return rate (your expected return minus expected inflation).
It compounds current savings plus regular contributions at an expected return rate until retirement age.
Only if adjusted specifically — otherwise the result is in nominal dollars.
Contributing earlier gives more time for compounding, often outweighing larger contributions made later.
