First payment one month after you get the money, payments rounded to the cent and all equal (at a 0% rate the last one can be a few cents higher, so the loan is fully repaid). A lender's disclosure can differ slightly.
This is an estimate to help you plan, not financial advice. Your bank, lender or plan may round, time or charge things differently.
How this is calculated
The monthly payment comes from the standard formula for equal monthly payments: payment = P × r ÷ (1 − (1 + r)−n), where P is the loan amount, r the yearly interest rate divided by 12, and n the number of months. Interest is charged on the full loan amount, even when the fee is taken out before you get the money.
Under the federal Truth in Lending rules (Regulation Z), a loan fee is part of the finance charge, the cost of the credit in dollars. A fee withheld from the loan or paid up front is a prepaid finance charge, and it is subtracted to get the amount financed: what you actually receive. The finance charge is everything you pay minus the amount financed, so it is the interest plus the fee.
Example: a $10,000 loan at 15% for 36 months with a 5% origination fee taken out. The fee is $500, so you receive $9,500. The payment is $346.65, and 36 payments add up to $12,479.40. The finance charge is $12,479.40 − $9,500.00 = $2,979.40: $2,479.40 in interest plus the $500 fee.
APR. Regulation Z's actuarial method finds the monthly rate at which 36 payments of $346.65 are worth exactly the $9,500 you received, then multiplies it by 12. Here that gives 18.67%, against an interest rate of 15%. Without the fee the APR would be 15.00%. The calculator solves for the rate exactly and rounds to two decimals. The Federal Reserve's APR tables give the nearest quarter point instead: their own example, a $65.11 finance charge on $332.20 over 24 months, reads 17.75% from the table, while the exact result is 17.81%.
Fee added to the loan. If the fee is added instead, you borrow the amount you need plus the fee. Here a percent fee is a percent of the amount you need; if your offer states the fee in dollars, switch to Dollars. With $10,000 needed and a 5% fee, the loan is $10,500.00, the payment $363.99, and the APR 18.49%. The amount financed stays $10,000.
APR by origination fee
| Fee | 24 months | 36 months | 60 months |
|---|---|---|---|
| 0% | 15.00% | 15.00% | 15.00% |
| 1% | 16.03% | 15.71% | 15.46% |
| 3% | 18.13% | 17.17% | 16.39% |
| 5% | 20.29% | 18.67% | 17.35% |
| 8% | 23.66% | 21.01% | 18.85% |
The same fee raises the APR more on a short loan, because it is spread over fewer payments.
Assumptions and limits. The first payment is due one month after you get the money, all payments are equal, and the payment is rounded to the cent. When there is interest, the last payment is not adjusted for that rounding, so the total of payments is the payment times the number of months; at a 0% rate, if rounding leaves the loan a few cents short, the last payment is raised by that amount. A lender that adjusts the last payment can show a different total (a few cents on a short loan, more on a very long one), and its APR can differ by hundredths of a point; Regulation Z counts an APR as accurate within 1/8 of a percentage point (1/4 point for irregular loans). The calculator does not include late fees, insurance, extra payments or a first period longer than a month.

Questions people ask
How much is the monthly payment on a $10,000 personal loan?
At 15% for 36 months it is $346.65. The payment depends on the interest rate, the loan amount and the term; a fee taken out of the loan does not change it.
How does an origination fee affect a personal loan?
A fee taken out of the loan lowers the cash you receive but not what you repay. On $10,000 with a 5% fee you get $9,500, still repay $12,479.40 at 15% over 36 months, and the APR rises from 15% to 18.67%.
What is the difference between the interest rate and the APR?
The interest rate sets the payment. The APR is the yearly cost of the credit including fees such as an origination fee, so it is the best single number to compare offers with the same term; for different terms, also compare the total of payments. With no fees, the two are the same.
How much do I need to borrow to get $10,000 after the fee?
Divide the amount you need by 1 minus the fee. With a 5% fee taken out, borrow $10,526.32: the fee is $526.32 and $10,000 is left.
What is the finance charge on a loan?
The dollar cost of the credit: all payments minus the amount you received, so interest plus fees. For $10,000 at 15% for 36 months with a 5% fee it is $2,979.40.
Why is the APR on my offer slightly different?
Lenders may count the days to the first payment or round the last payment differently. Regulation Z treats an APR as accurate if it is within 1/8 of a percentage point of the exact figure.
