Formula Explained

The future value of money after deductions is calculated using the following formula:

Future Value (FV) = P × (1 + r)^n - D × [(1 + r)^n - 1] / r

Where:

P = Initial investment amount
r = Annual interest rate (in decimal form)
n = Number of years
D = Annual deduction amount

This formula accounts for the growth of your investment and the impact of annual deductions. The first part of the formula calculates the future value of the initial investment without deductions, and the second part accounts for the deductions made each year.

Worked Example

Let's say you invest $10,000 with an annual interest rate of 5%, and you plan to invest for 10 years with an annual deduction of $1,000. Here's how the calculation works:

Future Value = $10,000 × (1 + 0.05)^10 - $1,000 × [(1 + 0.05)^10 - 1] / 0.05

Future Value ≈ $10,000 × 1.6289 - $1,000 × 15.289 / 0.05

Future Value ≈ $16,289 - $30,578

Future Value ≈ $14,231

In this example, the future value of your investment after accounting for annual deductions is approximately $14,231.
