1. What is the Amex High Yield Savings Calculator?

The Amex High Yield Savings Calculator estimates the growth of your savings with American Express's high-yield savings account, which currently offers 3.60% APY. It calculates daily compounding interest to show your potential earnings over time.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

Where:

• \( A \) — Final amount ($)
• \( P \) — Principal amount ($)
• \( r \) — Annual interest rate (decimal, e.g., 0.036 for 3.6%)
• \( t \) — Time in years

Explanation: The formula accounts for daily compounding (365 times per year), which maximizes your earnings compared to simple interest or less frequent compounding.

3. Importance of Daily Compounding

Details: Daily compounding means interest is calculated on your principal plus previously earned interest every day, leading to exponential growth over time. This is why high-yield savings accounts can significantly outperform traditional savings accounts.

4. Using the Calculator

Tips: Enter your initial deposit in dollars, the annual interest rate as a decimal (default is 0.036 for 3.6% APY), and the time period in years. All values must be positive numbers.
