What Does This Loan Really Cost?

A low monthly payment can hide a high total cost. Enter the loan amount, rate, term, and fees to see the payment, lifetime interest, total borrowing cost, total dollars paid, and an estimated fee-adjusted APR.

Your true-cost estimate

The sample values are calculated automatically. Change the assumptions to see your own estimate.

These calculators provide mathematical planning estimates, not financial, tax, legal, or investment advice. Actual rates, returns, fees, taxes, market values, and lender practices can change the result.

Understand the result

Separate the rate from the cost of borrowing

The stated interest rate determines the scheduled principal-and-interest payment, but fees can increase what the financing truly costs. An origination fee may even be withheld from proceeds, meaning you receive less cash than the principal balance you must repay.

The calculator therefore shows both the contractual payment math and a fee-adjusted annualized rate based on entered cash flows.

Compare offers using the same assumptions

  • Use the same loan amount and term for each lender.
  • Enter origination and closing fees instead of comparing rate alone.
  • Compare total borrowing cost as well as monthly payment.
  • Remember that legal APR disclosures may treat individual fees differently.

Frequently asked questions

Is the fee-adjusted APR the same as a lender’s legal APR disclosure?

Not necessarily. This calculator is a cash-flow estimate. Regulatory APR rules may include or exclude specific charges differently.

Why are origination fees important?

They can reduce the cash you receive while you still repay the full principal balance.

Does the calculator assume I keep the loan for the full term?

Yes. Total interest and total cost assume the scheduled loan is held to maturity.
