Compare the stated interest rate with an annualized fee-adjusted borrowing-rate estimate using the entered financed amount and payment stream.

Loan amount

Note rate (%)

Fee-adjusted annualized estimate

—

Simplified monthly-cash-flow APR estimate

—Monthly P&I

—Amount financed

—APR − note rate

—Charges / loan

Estimate the effect of upfront finance charges

Enter the loan amount, stated note rate, term, and the upfront charges you want included. The tool finds the monthly discount rate whose payment stream matches the reduced amount financed, then annualizes that monthly rate.

Not an official disclosure engine

Mortgage APR disclosures can depend on legally defined finance charges, timing, mortgage insurance treatment, odd first periods, and other rules. Use lender disclosures for an official transaction APR.
