Method, policy basis, and limitations
How the estimate is built
The remaining balance accrues interest by payment period before the contractual and extra payments reduce principal, producing baseline and accelerated payoff schedules.
Important limitation
This is an amortization estimate. Lender rounding, escrow, insurance, fees, variable rates, payment timing, arrears, and prepayment restrictions can change the actual payoff quote.
Your inputs
Enter the values you know. Required fields should be completed first, and optional fields can be left blank if they do not apply to your situation.
