1. What is the Monthly Interest Calculator?

The Monthly Interest Calculator for Capital One savings accounts calculates the monthly interest earned based on your principal amount and annual interest rate. This helps you understand how much your savings will grow each month.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( P \) — Principal amount (USD)
• \( R \) — Annual interest rate (decimal)
• \( I \) — Monthly interest earned (USD)

Explanation: The formula divides the annual interest rate by 12 to get the monthly rate, then multiplies by the principal amount to calculate monthly interest earnings.

3. Importance of Interest Calculation

Details: Understanding monthly interest earnings helps in financial planning, comparing savings account options, and projecting future savings growth with Capital One accounts.

4. Using the Calculator

Tips: Enter your principal amount in USD and annual interest rate as a decimal (e.g., 0.05 for 5%). Both values must be positive numbers.
