Formula Used
The calculator uses the compound interest formula to calculate your future savings balance:
Future Balance = Initial Deposit × (1 + Interest Rate)ᴺᴱᴿᴹ
Total Interest = Future Balance - Initial Deposit
Where:
- Initial Deposit is the amount you start with
- Interest Rate is the annual percentage yield (APY)
- Term is the number of years the money will be saved
Note: This calculator assumes the interest is compounded annually. For more precise calculations, you may need to consider the actual compounding frequency of your specific Amex savings account.
Worked Example
Let's calculate the future value of $5,000 saved for 5 years at an annual interest rate of 2.5%:
Future Balance = $5,000 × (1 + 0.025)⁵
Future Balance = $5,000 × 1.13207
Future Balance = $5,660.35
Total Interest = $5,660.35 - $5,000 = $660.35
After 5 years, you would have $5,660.35 with $660.35 in interest earned.
Interest Rate Comparison
Compare how different interest rates affect your savings growth over time:
| Initial Deposit | Interest Rate | Term (Years) | Future Balance | Total Interest |
|---|---|---|---|---|
| $5,000 | 1.0% | 5 | $5,050.00 | $50.00 |
| $5,000 | 2.0% | 5 | $5,100.41 | $100.41 |
| $5,000 | 2.5% | 5 | $5,660.35 | $660.35 |
| $5,000 | 3.0% | 5 | $5,776.50 | $776.50 |
As you can see, even small differences in interest rates can significantly impact your long-term savings growth.
