Formula used

The future value of a 529 investment account is calculated using the compound interest formula:

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

Where:

P = Initial investment amount
PMT = Annual contribution amount
r = Annual interest rate (as a decimal)
n = Number of years

This formula accounts for both the initial investment and regular contributions, with interest compounded annually.

Worked example

Let's calculate the future value of a 529 investment account with the following parameters:

Initial investment: $10,000
Annual contribution: $2,000
Investment period: 18 years
Annual return: 7%

Using the formula:

Future Value = $10,000 × (1 + 0.07)^18 + $2,000 × [(1 + 0.07)^18 - 1] / 0.07

Calculating each part:

(1 + 0.07)^18 ≈ 3.73
$10,000 × 3.73 ≈ $37,300
[(1 + 0.07)^18 - 1] / 0.07 ≈ 26.33
$2,000 × 26.33 ≈ $52,660

Total Future Value ≈ $37,300 + $52,660 = $89,960

This example shows that with consistent contributions and a 7% annual return, you could have approximately $89,960 in your 529 account after 18 years.
