Your estimate

Enter values, then calculate.

How the estimate works

Fees are deducted from the face amount at funding. Monthly payments amortize the full face amount at the note rate. The fee-adjusted rate solves for the monthly discount rate at which those payments equal the net cash received, then multiplies it by 12.

Method source

CFPB: interest rates and fees in loan comparisons. Background guidance; the assumptions and specific model are described above.

Important limitation

Fixed-rate equal monthly payments only. No balloon, daily repayment, deferred payment, variable rates, financed fee option or prepayment is assumed. A lower lifetime dollar cost can reflect less usable funding or a shorter term; there is no automatic winner. Results are estimates only and are not financial, lending, legal, tax, or investment advice.

Frequently asked questions

Why is the estimated rate above the note rate?

Fees reduce the cash you receive while repayments still amortize the face amount. The implied borrowing rate reflects that smaller starting cash inflow.

Is this the lender's legally disclosed APR?

No. It is an estimated annualized monthly IRR for these cash flows. Required disclosures and included charges vary; obtain the actual lender documents.

Can I compare different repayment schedules?

This version supports equal monthly fixed-rate payments. Different terms are allowed, but daily/weekly payments, balloons and variable rates are outside the model.
