APR Calculator
Calculate a loan's effective APR by accounting for upfront fees on top of the stated interest rate.
Example
A $200,000 loan at a 6% note rate over 30 years has a monthly payment of $1,199.10. Add $4,000 in upfront fees, so you only net $196,000. Solving for the rate that discounts the $1,199.10 payments back to $196,000 gives an effective APR of about 6.190% — higher than the 6% note rate because of the fees.
How it works
Enter the loan amount, note (stated) rate, term, and upfront fees; the tool computes the monthly payment on the full amount, then solves for the rate that equates your net proceeds (amount minus fees) to that payment stream. That rate, annualized, is your APR.
Good to know
The APR Calculator turns a loan's quoted (note) rate into its true annual percentage rate by folding in the upfront fees you pay to get the money. You type in the loan amount, the stated interest rate, the term in years or months, and any origination or finance fees, and it returns the effective APR alongside the monthly payment, your net proceeds, the total of all payments, and total interest. It's built for borrowers comparing mortgage, auto, or personal-loan offers and anyone who wants to see past a low advertised rate.
Reach for it whenever two loans have different fee structures, because the headline interest rate alone can be misleading. A loan with a slightly lower note rate but heavy origination points can actually cost more than one with a higher rate and no fees. Running each offer through the same calculator puts them on a single comparable number, which is exactly why lenders are required to disclose APR in the first place.
To read the result, focus on the gap between the APR and the note rate: that spread is the cost of your fees expressed as an interest rate. The calculator keeps your payment fixed at the note rate on the full balance, then solves for the rate that discounts those payments back to what you actually received (loan amount minus fees). The stacked Principal, Interest, and Fees bars show where your total outlay goes, and "Net proceeds" is the cash you really walk away with.
- Tip: APR shrinks toward the note rate the longer you hold the loan, because fixed upfront fees get spread over more payments. If you expect to refinance or pay off early, your real cost is higher than the displayed APR suggests, so this figure is most accurate when you keep the loan for its full term.
Frequently asked questions
Why is the APR higher than the interest rate I was quoted?
Your monthly payment is based on the full loan amount at the note rate, but upfront fees mean you actually receive less cash (net proceeds). The APR is the rate that reflects paying the same payments on a smaller amount, so it ends up higher than the note rate whenever fees are charged.
What counts as upfront fees for APR?
Generally finance charges paid to get the loan: origination or processing fees, points, underwriting and some closing costs. Third-party costs like appraisal or title insurance may or may not be included depending on the lender and jurisdiction, so enter the fees your lender treats as part of the finance charge.

People also ask
What is the difference between APR and interest rate?
The interest rate (or note rate) is the cost of borrowing the principal alone, while APR adds in upfront fees and certain finance charges to show the total yearly cost of the loan. APR is therefore equal to or higher than the note rate, and it is the better number for comparing offers.
How is APR calculated on a loan?
The monthly payment is figured from the full loan amount at the note rate, then a rate is found that discounts that stream of payments back to your net proceeds (the loan amount minus upfront fees). That solved monthly rate, multiplied to an annual figure, is the APR.
Does a lower APR always mean a cheaper loan?
Usually, but not always, because APR assumes you keep the loan for its full term. If you pay off or refinance early, a loan with lower fees but a higher APR can end up cheaper since you avoid spreading fees over fewer payments.
Is APR the same as APY?
No. APR describes the cost of borrowing and does not compound, while APY (annual percentage yield) describes earnings on savings or investments and includes the effect of compounding. They are used for opposite sides of a transaction.
Why are upfront fees included in APR but not in the monthly payment?
Upfront fees are typically paid at closing rather than financed into the monthly payment, so they do not change the payment amount. They reduce the cash you actually receive, which is why they raise the effective APR without altering the payment.
Can APR be lower than the interest rate?
In a standard loan, no. With no fees the APR equals the note rate, and any finance charges push it above the note rate. A quoted APR below the note rate generally signals lender credits, rebates, or a non-standard calculation.
Does APR include closing costs on a mortgage?
It includes the finance-charge portion of closing costs, such as origination fees, points, and underwriting. Third-party costs like appraisal, title insurance, or recording fees may or may not be counted depending on the lender and applicable rules.
How do points affect the APR of a loan?
Discount or origination points are upfront fees, so they increase the APR even though they may lower the note rate. The calculator captures this by counting points as part of upfront fees, which reduces net proceeds and raises the effective rate.
