APR Calculator
Calculate the Annual Percentage Rate (APR) for any loan — the true cost of borrowing including fees, interest, and compounding. Compare loan offers with confidence.
What Is APR (Annual Percentage Rate)?
The Annual Percentage Rate (APR) is the annual rate charged for borrowing money, expressed as a percentage that represents the actual yearly cost of funds over the term of a loan. APR includes the nominal interest rate plus any additional fees or charges associated with the loan, such as origination fees, closing costs, or mortgage insurance.
Unlike the nominal interest rate, APR gives you a more complete picture of what you'll actually pay each year. That's why it's often higher than the stated interest rate — and why it's the best number to compare when shopping for loans.
How Does the APR Calculator Work?
This calculator determines the APR by finding the interest rate that makes the present value of all loan payments (including fees) equal to the amount you receive. It uses the following approach:
Loan Amount = PV of all payments at APR
Where:
PV = Present Value of all periodic payments (discounted at APR)
Fees = Added to the effective loan balance
APR = Solved iteratively so that the equation holds.
The calculator also generates a full amortization schedule so you can see exactly how much of each payment goes toward principal versus interest.

💡 Pro Tip: When comparing loans, always look at the APR — not just the nominal interest rate. A loan with a lower nominal rate but high fees can actually cost you more than a loan with a slightly higher rate and low fees.
❓ APR FAQ
What is APR?
APR stands for Annual Percentage Rate. It's the annual cost of borrowing money, expressed as a percentage. It includes both the nominal interest rate and any fees or additional costs associated with the loan.
How is APR different from the interest rate?
The interest rate is the cost of borrowing the principal loan amount. APR includes the interest rate plus other costs like origination fees, closing costs, and mortgage insurance. APR is always equal to or higher than the nominal interest rate.
Why is APR important?
APR helps you compare loan offers from different lenders. Since it includes fees and other costs, it gives you a more accurate picture of what you'll actually pay over the life of the loan.
What is the difference between APR and APY?
APR (Annual Percentage Rate) is used for loans and does not include the effect of compounding. APY (Annual Percentage Yield) is used for savings and investments and includes compounding interest. APY is typically higher than APR for the same nominal rate.
How does compounding affect APR?
Compounding frequency affects how interest is calculated. More frequent compounding (e.g., daily) results in a higher effective annual rate. Our calculator lets you choose different compounding frequencies to see the impact on APR.
What fees are included in APR?
APR typically includes origination fees, underwriting fees, closing costs, mortgage insurance premiums, and points. It does not usually include late fees, prepayment penalties, or fees for optional services like appraisals or credit reports.
Is a lower APR always better?
Generally yes — a lower APR means you'll pay less over the life of the loan. However, consider the loan term and other features. Sometimes a slightly higher APR might be worth it for a shorter term or more favorable terms.
What is a good APR for a loan?
It depends on the type of loan, your credit score, and market conditions. For mortgages, APRs typically range from 5–10%. For personal loans, they can range from 5–36%. Compare offers from multiple lenders to find the best APR for your situation.
How do I calculate APR manually?
APR is calculated by finding the interest rate that equates the present value of all loan payments with the loan amount plus fees. It's an iterative process — our calculator does this automatically for you.
Can APR change over the life of a loan?
For fixed-rate loans, the APR is locked in at the time of origination. For adjustable-rate loans, the APR can change when the interest rate adjusts. Always read the loan terms carefully to understand how your rate might change.
What is the difference between APR and effective APR?
Effective APR includes the effect of compounding, while standard APR typically assumes simple interest. In practice, many lenders use APR interchangeably with effective APR when discussing loans with compounding.
Does APR include taxes and insurance?
No, APR does not include taxes or insurance. It's focused on the financing costs of the loan itself. Taxes and insurance are separate expenses that may be added to your monthly payment (e.g., in an escrow account).
