1. What is the Ally Savings Formula?

The Ally High Yield Savings formula calculates the future value of an investment with daily compounding interest. It's particularly relevant for Ally Bank's high-yield savings accounts which compound interest daily.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

Where:

• \( A \) — Final amount ($)
• \( P \) — Principal investment amount ($)
• \( r \) — Annual interest rate (decimal, e.g., 0.0425 for 4.25%)
• \( t \) — Time the money is invested for (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 any accumulated interest every day, leading to faster growth of your savings compared to monthly or annual compounding.

4. Using the Calculator

Tips: Enter your initial deposit amount in dollars, the annual interest rate as a decimal (e.g., 0.0425 for 4.25%), and the number of years you plan to keep the money in the account.
