APR Calculator

How this result is built

Turn a note rate and upfront fees into an annual percentage rate for a fixed loan.

The note rate sets the payment. APR answers a different question: what rate, charged on the money you effectively received, would produce that same payment? Upfront fees make the APR higher than the note rate because you did not keep the full loan amount.

What the opening example is for

APR is for comparison. Two offers with the same payment can have different APRs when one hides costs in fees. It is not the number used to build the amortization schedule.

The walkthrough below uses the numbers already sitting in APR Calculator. Press Calculate and the headline should match this page. Then put your own figures in. The math does not run until you press the button, and Clear hides the result.

What each field is doing

The “Loan amount” line on APR Calculator starts at $25,000.00. Leave that figure only when it matches the statement, the quote, or the plan you are testing. Press Calculate after the edit so the chart and the schedule move with it.

APR Calculator treats “Note rate” as its own entry, and the form opens with 8%. A round example is useful for learning the page. It is a poor substitute for the number on your own paperwork, so replace it and run the form again.

The remaining fields

Before you replace it, “Upfront fees” reads $750.00 on APR Calculator. The other fields stay put while you change this one. That is the clean way to see what this line is doing inside the result.

Look at “Term” first if you are checking APR Calculator: the filled value is 5. If the label is a rate, type the annual figure the contract uses. If it is money, type the amount that will actually move, not a rounded hope.

The opening result, line by line

Press Calculate on the opening form and APR is 9.30%. That is the number the rest of this section is talking about.

Note rate is 8.00% when you run the opening figures on APR Calculator. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

On this opening pass, monthly payment is $506.91. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

APR Calculator reports that amount after upfront fees is $24,250.00. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

How those lines were produced

Fees is $750.00 when you run the opening figures on APR Calculator. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

APR folds upfront fees into the rate. It does not describe a different monthly payment.

A second pass changes only “Loan amount”, from $25,000.00 to $27,500.00. APR moves from 9.30% to 9.18%. Nothing else on the form was edited, so the gap between those two results is the effect of that one field on APR Calculator. If the gap is tiny, this page is not very sensitive to that entry. If the gap is large, get that entry from a document before you plan around the result.

What this page will not claim

APR Calculator does not know your credit score, the county’s tax bill, or what an appraiser will say. Type the price, the loan, and the escrow you were quoted. Compare the payment with the loan estimate, and treat a small rounding difference as normal.

APR Calculator stops at its own formula. When the next question is different, open Personal Loan Calculator (Note amount, fee, payment, and APR.); Business Loan Calculator (Note rate and fees, stated as APR.); Refinance Calculator (Break-even months against the interest you still pay.). Do not add those results to this one as if they were the same kind of dollar.

Check the result before you use it

Start on APR Calculator by reading the labels, not the headline. The opening labels are Loan amount ($25,000.00), Note rate (8%), Upfront fees ($750.00), Term (5). If a label is not the fact you have, the result cannot turn into that fact later. The illustration on the form lands on 9.30%. When you press Calculate and see that same figure, the button and this explanation are using one formula.

Change one field at a time. Write down the headline, edit a single line, and press Calculate again. A large jump means that line carries the result. A line that does not move is a line the formula ignores, which is a reason to confirm you opened the right page. APR Calculator is built for one job: The rate that includes upfront fees. The description on the page says the same thing in a sentence: Turn a note rate and upfront fees into an annual percentage rate for a fixed loan.

When the paperwork disagrees

Then hold the headline next to a source outside the site. That source might be a loan estimate, an account statement, a pay stub, or the public limit named in the methodology. A few cents of difference on a long schedule is ordinary rounding. A different rate, a fee you never typed, or a tax the form does not ask for is not rounding. Correct the input. Do not average the page with the paperwork.

When the outside source still disagrees, APR Calculator has reached the edge of what it will claim. It will not phone a lender, pull a county record, or apply a credit you left blank. Send the calculator name, every input, and the result you expected through the contact page if you think the formula itself is wrong. Until that is settled, read 9.30% as the output of the fields above and nothing else.
