1. What is the Amex Savings Calculator?

The Amex Savings Calculator helps you estimate the growth of your money in an American Express High Yield Savings Account using daily compound interest. It calculates how much your savings will grow over time based on the current APY (Annual Percentage Yield).

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( A \) — Final amount
• \( P \) — Principal amount (initial investment)
• \( r \) — Annual interest rate (in decimal)
• \( t \) — Time in years

Explanation: The formula accounts for daily compounding (365 times per year), which is how American Express calculates interest on their high-yield savings accounts.

3. Importance of Compound Interest

Details: Compound interest allows your savings to grow exponentially over time as you earn interest on both your principal and accumulated interest. The more frequently interest is compounded, the faster your money grows.

4. Using the Calculator

Tips: Enter your initial deposit, the current APY (default is 4.25% which is Amex's typical rate), and the number of years you plan to save. All values must be positive numbers.
