What the calculator shows
Enter principal, annual contract interest rate, term, origination fee and optional extra payment. Choose whether the fee is financed or withheld from proceeds so the result shows both amount financed and cash received.
Calculation method
The entered contract rate drives fixed monthly amortization. A financed fee joins principal before interest is calculated; a withheld fee reduces cash received and is added to total cost. Extra payments reduce principal and the final payment is limited to the amount due.
Inputs to confirm
Use the contract rate that produces the scheduled payments. Compare the result with the Truth in Lending payment, finance charge, amount financed and APR, then match prepayment rules and fee treatment to the agreement.
Worked fee-treatment example
With $15,000 principal, no fee, 11.86% and 24 months, the payment is $705.12 and interest is $1,922.92. A financed fee would increase the balance and payment; a withheld fee would keep the modeled balance but reduce cash received.
| Scenario | Interest-bearing balance | Cash available |
|---|---|---|
| No origination fee | $15,000 | $15,000 |
| $750 fee financed | $15,750 | $15,000 |
| $750 fee withheld | $15,000 | $14,250 |
Compare cash received, financed balance and disclosed APR
An origination fee can either increase the balance or reduce the cash delivered. Those two treatments can have the same headline fee but different payment and usable-proceeds results.
Financed and withheld fees change different parts of the loan
A financed fee joins principal and accrues interest. A withheld fee does not increase the amortized balance but reduces net proceeds, so the borrower receives less cash than the stated principal. Select the treatment shown in the lender disclosure.
The interest rate is not the same measure as APR
The entered contract rate produces the payment schedule. APR is designed for comparison and may include origination or other covered finance charges. This calculator displays fee effects but does not derive a regulated APR from exact dated cash flows.
Extra payments need contract confirmation
The scenario applies the same extra amount to principal every month and estimates an earlier payoff. A real agreement may specify payment allocation, due dates, late fees or prepayment conditions, so confirm the payoff quote before acting.
| Treatment | Balance charged interest | Cash received |
|---|---|---|
| No fee | Entered principal | Entered principal |
| Fee financed | Principal plus fee | Entered principal |
| Fee withheld | Entered principal | Principal minus fee |
