APR Calculator
Calculate the true cost of a loan including all fees
How to Use This APR Calculator
- Enter the total loan amount you're borrowing
- Input the stated interest rate from the lender
- Specify the loan term in months
- Enter all upfront fees: origination fees, points, application fees
- Add any other required fees (document prep, underwriting, etc.)
- Click 'Calculate APR' to see the true cost of borrowing
Example: A $25,000 loan at 6.5% for 60 months with $500 origination fee and $200 other fees has a true APR of 7.12%. The fees add 0.62% to the effective rate, meaning you're actually paying $700 more in total borrowing costs than the 6.5% rate suggests.
Tip: When comparing loan offers, always compare APR to APR, not interest rate to APR. The loan with lower interest rate isn't always cheaper if it has higher fees.
Why Use a APR Calculator?
APR reveals the true cost of borrowing by including all fees, making it essential for comparing loan offers fairly.
- Compare mortgage offers with different rate and fee combinations
- Evaluate auto loan options from dealers vs banks vs credit unions
- Determine if paying points for a lower rate is worthwhile
- Understand the real cost of personal loans with origination fees
- Compare credit card offers beyond just the interest rate
- Make informed decisions on refinancing by knowing true costs
Understanding Your Results
APR represents your true annual cost of borrowing. Here's how to interpret the difference between stated rate and APR.
| Result | Meaning | Action |
|---|---|---|
| APR < 0.25% above rate | Low-fee loan | Fees are minimal; good deal if rate is competitive |
| APR 0.25-0.5% above rate | Moderate fees | Normal range for most loans; compare to alternatives |
| APR 0.5-1% above rate | High fees | Significant upfront costs; consider negotiating or other lenders |
| APR > 1% above rate | Very high fees | Fees are substantial; strongly consider alternatives |
Meaning: Low-fee loan
Action: Fees are minimal; good deal if rate is competitive
Meaning: Moderate fees
Action: Normal range for most loans; compare to alternatives
Meaning: High fees
Action: Significant upfront costs; consider negotiating or other lenders
Meaning: Very high fees
Action: Fees are substantial; strongly consider alternatives
Note: APR impact is greater on shorter-term loans. $1,000 in fees on a 5-year loan raises APR more than the same fees on a 30-year loan.
About APR Calculator
Formula
APR is calculated by finding the rate that makes the present value of all payments equal to the loan amount minus fees The calculation uses iterative methods (Newton-Raphson) to find the rate where: Net Loan = Sum of [Payment / (1 + APR/12)^month] for all payments. This effective rate accounts for paying fees upfront while benefits spread over time.
Current Standards: Federal Truth in Lending Act (TILA) requires APR disclosure for consumer credit. Mortgage APR includes points, origination fees, and mortgage insurance. Credit card APR must include annual fees in certain calculations.
Frequently Asked Questions
Why is APR higher than the interest rate?
APR includes upfront fees spread across the loan term. When you pay $700 in fees on a $25,000 loan, you only receive $24,300 but pay interest on $25,000. This discrepancy - paying for money you didn't actually get - increases your effective rate. APR captures this true cost.
Should I always choose the loan with lower APR?
Usually, but not always. If you might refinance or pay off early, a lower rate with higher upfront fees (higher APR) might actually cost more. APR assumes you keep the loan full term. For loans you'll pay off early, compare total costs for your expected timeframe instead.
What fees should be included in APR?
Include all fees required to get the loan: origination fees, points, application fees, underwriting fees, document preparation, and mortgage insurance. Don't include optional items (like title insurance you'd pay anyway) or true third-party fees (like property appraisals at cost).
How do points affect APR?
Discount points (prepaid interest to lower your rate) increase APR on shorter-term comparisons but may lower total cost over the full loan term. One point (1% of loan) typically lowers the rate by 0.25%. Calculate break-even point: if fees are $2,500 and you save $50/month, break-even is 50 months.
Is APR the same as interest rate for credit cards?
For credit cards, APR and interest rate are often the same because cards typically don't have upfront fees (annual fees are disclosed separately). However, if you carry a balance, understand that credit card APR is the rate charged on outstanding balances, and daily compounding means the effective annual rate is slightly higher.
