Horizon borrowing cost = entered upfront charges + other entered closing costs + interest accrued through the selected horizon + entered required monthly charges. Principal repayment is not treated as a borrowing cost.

Fee-classification guardrail

Do not dump every closing cost into APR

Use the APR-included field only for charges you are intentionally treating as finance charges for this estimate. Put appraisal, title, recording, taxes, homeowners insurance and other costs you are not treating as APR finance charges in the separate closing-cost field. Actual legal classification can differ by transaction.

Loan Estimate cross-check

Mortgage APR appears in the Comparisons section of the Loan Estimate. Enter that disclosed APR above to see the gap from this model instead of assuming the estimate must match.

Method & limits

Regular fixed-rate monthly-payment model

The scheduled P&I payment is calculated from the full loan amount and note rate.
Discount points and other entered APR-included upfront charges reduce the amount financed used in the APR solve.
Any required monthly charge you enter is added to the payment stream for exactly the number of months you specify.
The APR is solved as the nominal annual rate (monthly actuarial rate × 12) whose discounted payment stream equals the modeled amount financed.
This is designed for a regular fixed-rate monthly payment stream. Odd first periods, adjustable rates, changing payments, financed fees and transaction-specific legal classifications can require different treatment.
Your creditor’s Loan Estimate or Closing Disclosure is the authoritative transaction disclosure; use this workspace to understand and compare, not to replace it.

Compare mortgage offers on more than the note rate

APR is a broader borrowing-cost measure because it combines the payment stream with certain finance charges. Use the two-offer workspace to see how discount points and entered APR charges change amount financed and the annualized cost of credit.

APR does not answer every comparison question

The regulatory APR assumes the disclosed payment structure over the loan term. The separate holding-period view shows entered upfront costs plus interest and required charges through the horizon you choose, without treating principal repayment as a borrowing cost.
