Discount points as a % of the loan (e.g., 1 point = 1%).
Other fees
Lender/underwriting/processing fees included in APR; excludes escrows.

How it works

We subtract points and fees from the loan amount to get amount financed.

Monthly payment uses the note rate on the full loan amount. APR is solved by finding the rate that equates the amount financed to the payment stream over the term.

Formula

Amount financed = Loan − (Points + Fees)
Payment = note rate amortization on full loan
APR solved as the periodic rate that discounts the payment stream to the amount financed, annualized.

When to use it

  • Comparing loan estimates across lenders on a consistent APR basis.
  • Seeing how points/credits change APR vs the note rate.
  • Understanding total finance charges beyond principal and interest.

Tips & cautions

  • Use the same inputs across lender quotes to compare APRs fairly.
  • If you’re not buying points, set points to 0; include only lender fees that factor into APR.
  • APR includes finance charges but not escrowed taxes/insurance/PMI.
  • Assumes fixed-rate, fully amortizing loan with monthly payments.
  • Does not include PMI, taxes, insurance, HOA, or prepayment penalties.
  • Uses a simplified APR solve; minor differences may exist vs lender disclosures.
