1. What is the Ally Savings Growth Formula?

The Ally Savings Growth Formula calculates how your money grows in an Ally savings account with daily compounding interest. It accounts for the principal amount, annual interest rate (APY), and time period.

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., 0.0425 for 4.25%)
• \( t \) — Time period in years

Explanation: The formula calculates daily compounding by dividing the annual rate by 365 and applying it over 365 days per year.

3. Importance of Daily Compounding

Details: Daily compounding means interest is calculated on your balance every day, including previously earned interest. This results in slightly higher returns than monthly or annual compounding.

4. Using the Calculator

Tips: Enter principal in dollars, annual rate as a decimal (e.g., 4.25% = 0.0425), and time in years. All values must be positive numbers.
