APR Calculator

Calculate Annual Percentage Rate including fees and interest

About this Tool

The APR (Annual Percentage Rate) calculator determines the true cost of borrowing by including both interest rates and all associated fees in a single percentage. Unlike simple interest rates, APR provides a complete picture of loan costs, making it easier to compare different loan offers fairly. By law, lenders must disclose APR for consumer loans, helping borrowers make informed decisions. This calculator accounts for origination fees, closing costs, processing fees, and other charges that affect the total cost of borrowing.

Common Use Cases

Loan Comparison

Compare different loan offers fairly by looking at APR instead of just interest rates. A lower rate with high fees may have a higher APR than a higher rate with no fees.

Mortgage Shopping

Evaluate mortgage offers from different lenders. Closing costs and points significantly affect APR, revealing the true cost of home financing.

Credit Card Analysis

Understand the real cost of credit card balances. Credit cards disclose APR including fees, helping you choose the best card for your usage pattern.

Auto Loan Decisions

Calculate the true cost of car financing including dealer fees, documentation charges, and other costs to negotiate better deals.

Pro Tips

  • !

    APR vs Interest Rate

    Interest rate is the cost of borrowing the principal. APR includes the interest rate plus all fees, points, and charges, showing the total cost as a percentage.

  • !

    Lower APR Isn't Always Better

    Consider loan terms and your plans. A 30-year mortgage with slightly higher APR but no prepayment penalty may be better than lower APR with restrictions if you plan to pay early.

  • !

    Watch for Variable APRs

    Credit cards and some loans have variable APRs that change with market rates. Initial low APRs may increase significantly, affecting long-term costs.

    Calculate Break-Even

    For mortgages with points (prepaid interest), calculate how long you need to keep the loan to break even on the upfront cost versus monthly savings.
