Formula Explained

The future value of an investment with regular contributions can be 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 (in decimal form)
  • n = Investment period in years

This formula accounts for both the initial investment and the regular contributions, with each contribution earning compound interest over time.

Worked Example

Let's say you want to calculate the future value of a retirement account with the following details:

  • Initial investment: $10,000
  • Annual contribution: $2,000
  • Annual return rate: 7%
  • Investment period: 20 years

Using the formula:

Future Value = $10,000 × (1 + 0.07)^20 + $2,000 × [(1 + 0.07)^20 - 1] / 0.07

Calculating each part:

  • (1 + 0.07)^20 ≈ 3.80
  • $10,000 × 3.80 ≈ $38,000
  • [(1 + 0.07)^20 - 1] / 0.07 ≈ 23.80
  • $2,000 × 23.80 ≈ $47,600

Total Future Value ≈ $38,000 + $47,600 = $85,600

This means your retirement account would be worth approximately $85,600 after 20 years with these investment details.
