Formula Explained
The future value of a retirement account is calculated using the following formula:
Future Value = P × (1 + r)^n + PMT × [(1 + r)^n - 1] / r
Where:
- P = Initial investment amount
- PMT = Annual contribution amount
- r = Annual return rate (as a decimal)
- n = Number of years
This formula accounts for both the initial investment and regular contributions, with each contribution earning compound interest over time.
Worked Example
Let's say you invest $10,000 initially, contribute $5,000 annually, expect a 7% annual return, and invest for 20 years.
Future Value = $10,000 × (1 + 0.07)^20 + $5,000 × [(1 + 0.07)^20 - 1] / 0.07
Calculating this gives you an estimated future value of approximately $250,000.
This example shows how compound interest can significantly grow your retirement savings over time.
