The calculator will display your projected savings after 15 years based on the inputs you provided. You can adjust the values to see how different scenarios affect your retirement savings.

Formula Explained

The retirement calculator uses the future value of an annuity formula to calculate your projected savings:

Future Value = P × (1 + r)^n + PMT × [(1 + r)^n - 1] / r Where: P = Current Savings r = Annual Return (as a decimal) n = Number of Years (15) PMT = Monthly Contribution

This formula accounts for both your current savings growing at the expected annual return and your monthly contributions compounded over 15 years.

Worked Example

Let's say you have $10,000 saved now, expect a 7% annual return, and plan to contribute $500 per month. Here's how the calculation works:

Future Value = $10,000 × (1 + 0.07)^15 + $500 × [(1 + 0.07)^15 - 1] / 0.07 Future Value ≈ $10,000 × 2.802 + $500 × 33.5 ≈ $28,020 + $16,750 ≈ $44,770

After 15 years, you would have approximately $44,770 saved for retirement.
