Tips: Enter the principal balance in currency units and the annual interest rate as a percentage. Both values must be positive numbers to get accurate results.

A: This provides a basic estimate. Actual interest calculations may vary based on the card issuer's specific methods, including daily compounding or grace periods.

A: APR (Annual Percentage Rate) includes both the interest rate and any additional fees, providing a more comprehensive cost of borrowing.
Q3: How can I reduce my monthly interest costs?
A: Paying more than the minimum payment, transferring balances to lower-rate cards, or paying off the balance completely can reduce interest costs.
Q4: Does this calculation include compounding?
A: This is a simple interest calculation. Most credit cards use daily compounding, which would result in slightly higher actual interest costs.
Q5: Why is it important to know my monthly interest cost?
A: Understanding your monthly interest cost helps you make informed decisions about debt management and can motivate you to pay down balances faster.
