Formula Used

The calculator uses the compound interest formula:

A = P × (1 + r/n)^(nt) where: A = the future value of the investment/loan, including interest P = the principal investment amount (the initial deposit or loan amount) r = the annual interest rate (decimal) n = the number of times that interest is compounded per unit t t = the time the money is invested or borrowed for, in years

For USAA accounts, we use n = 365 (daily compounding) to provide the most accurate estimate of interest earned.

Worked Examples

Example 1: Savings Account

If you have a USAA savings account with $5,000 balance and a 2.5% APY, here's how the calculation works:

A = 5000 × (1 + 0.025/365)^(365×1) = 5000 × (1 + 0.00006849)^365 = 5000 × 1.02568 = $5,128.40

You would earn approximately $128.40 in interest after one year.

Example 2: Certificate of Deposit

For a USAA CD with $10,000 balance and 3.2% APY over 2 years:

A = 10000 × (1 + 0.032/365)^(365×2) = 10000 × (1 + 0.0000877)^730 = 10000 × 1.0663 = $10,663.00

You would earn approximately $663.00 in interest over two years.
