Calculate the true annual percentage rate including all loan fees and closing costs.
Calculated APR
vs 0.000% interest rate
On a $250,000 loan at 6.500% interest with $0 in fees, your APR is 6.500% and your monthly payment is $1,580. Compare APR — not just interest rate — to find the cheapest deal.

Understanding Annual Percentage Rate (APR)
What is APR?
APR (Annual Percentage Rate) is the true cost of borrowing expressed as a yearly rate. Unlike the stated interest rate, APR includes all mandatory fees: origination fees, discount points, and lender charges. This makes APR the most accurate way to compare loans.
How Loan Fees Affect APR
Fees have a disproportionate impact on short-term loans. A $2,000 fee on a 3-year loan increases APR significantly more than the same fee on a 30-year mortgage. This is why comparing APR is essential — especially for auto loans and personal loans where fees can dramatically increase the true cost.
When APR Matters Most
- Mortgages: Small APR differences mean thousands in savings over 30 years
- Auto loans: High fees can make a "0% interest" deal more expensive than a low-rate loan
- Personal loans: Origination fees often add 1–5% to the true cost
Closing Costs in APR
APR includes most closing costs charged by the lender: origination fees, discount points, underwriting fees, and processing charges. However, third-party costs like appraisal fees, title insurance, and recording fees are typically excluded. Always ask lenders which fees are included in their quoted APR.
How We Calculate APR
Our Calculation Method
This calculator computes APR by finding the interest rate that equates the net amount received (loan amount minus fees) with the present value of all scheduled payments. We use the Newton-Raphson iterative method to solve for the rate, which is the standard numerical approach for APR determination.
Regulation Z & TILA
Under the Truth in Lending Act (TILA) and its implementing regulation, Regulation Z (12 CFR Part 1026, Section 1026.22), lenders must disclose APR using the "net amount financed" method. Our calculator uses a simplified version of this approach. The APR your lender quotes may differ slightly due to differences in fee inclusion, rounding rules, and compounding conventions required by Regulation Z. Always compare this estimate against your lender's official TILA disclosure.
Frequently Asked Questions
A good APR depends on the loan type. For mortgages, under 7% is competitive. For auto loans, under 6% is good. For personal loans, under 10% is solid. Credit cards average 20-25% APR. Always compare multiple offers to find the best rate for your credit profile.
Yes, APR is almost always higher than the stated interest rate because it includes loan fees, origination fees, and closing costs. The interest rate only reflects the cost of borrowing, while APR shows the true loan cost including all fees spread over the loan term.
Yes, APR includes most closing costs such as origination fees, discount points, and lender fees. However, it typically excludes third-party costs like appraisal fees, title insurance, and recording fees. Always ask your lender which fees are included in the quoted APR.
Your APR is higher because it includes the cost of loan fees amortized over the loan term. If you paid $3,000 in fees on a $250,000 loan, the APR accounts for that upfront cost spread over 30 years, making it a more accurate representation of your true borrowing cost.
Credit cards have multiple APRs for different transaction types: purchase APR for regular purchases, cash advance APR (usually higher) for ATM withdrawals, balance transfer APR for moving debt from other cards, and penalty APR (the highest) for late payments. Each applies to different balances.
Paying discount points upfront lowers your interest rate, but may not significantly lower your APR. Points are included in the APR calculation, so while your monthly payment decreases, the APR shows the true cost including those upfront points. Points typically make sense if you keep the loan 5+ years.
