APR vs Interest Rate: What's the Difference?

The Short Answer

• Interest Rate: The cost of borrowing money, expressed as a percentage of the loan
• APR (Annual Percentage Rate): The interest rate PLUS fees, expressed as a yearly rate

APR is always equal to or higher than the interest rate because it includes additional costs.

Why This Matters

When comparing loans, the interest rate alone doesn't tell the whole story. Two loans with the same interest rate can have very different APRs if one has higher fees.

• Loan A: 8% interest rate, $1,000 in fees = 9.5% APR
• Loan B: 8% interest rate, $200 in fees = 8.3% APR

Even though both have the same interest rate, Loan B is cheaper overall.

What's Included in APR?

For Mortgages: - Interest - Origination fees - Mortgage insurance - Discount points - Closing costs (some)

For Installment Loans: - Interest - Origination fees - Application fees

For Credit Cards: - Interest only (fees are disclosed separately)

APR for Credit Cards Works Differently

Credit card APR is essentially the same as the interest rate because card companies don't wrap fees into APR. However, you need to separately consider:

• Annual fees
• Balance transfer fees
• Cash advance fees
• Foreign transaction fees

Fixed vs. Variable APR

Fixed APR - Stays the same throughout the loan term - Easier to budget - Common for installment loans and mortgages

Variable APR - Changes based on an index rate (like Prime Rate) - Can go up or down - Common for credit cards and HELOCs

How to Compare Loans Using APR

1. Get quotes from multiple lenders - Request the APR, not just the rate
2. Compare APRs for the same loan term - A 15-year mortgage will have a different APR than a 30-year
3. Consider your timeline - If you'll pay off early, low fees matter more than low APR
4. Look at total cost - Multiply monthly payment by number of payments

The Limitations of APR

APR isn't perfect for comparison because:

• It assumes you keep the loan for the full term - Not realistic for mortgages
• It doesn't account for compounding - Credit cards compound daily
• Variable rates change - Today's APR may not be tomorrow's

Key Takeaways

1. Always ask for APR, not just interest rate
2. Lower APR = lower total cost (usually)
3. Compare apples to apples - Same loan terms, same type of product
4. Don't forget other fees - Especially with credit cards

Ready to Compare?

Now that you understand APR, you're better equipped to find the best deal. Compare loan offers or credit card offers with confidence.
