Estimate how extra monthly and one-time payments may shorten your mortgage payoff timeline.
Payoff planning
A mortgage payoff calculator helps borrowers estimate how additional payments can change the payoff timeline. Extra principal payments reduce the balance sooner, which can reduce future interest and shorten the loan.
This tool estimates the original payoff timeline, new payoff timeline, interest saved, and time saved using both extra monthly payments and a one-time extra payment. It is useful for comparing payoff acceleration strategies.
Use it with the Extra Payment Calculator, Amortization Calculator, and Mortgage Calculator.

Guide
Mortgage payoff acceleration works by reducing principal faster than the original schedule. Since interest is calculated from the remaining balance, lowering the balance sooner can reduce future interest and shorten the payoff timeline.
This calculator first estimates the original payment based on balance, rate, and remaining term. It then simulates payoff with the same payment plus an extra monthly amount and a one-time extra payment applied at the start.
For example, a $280,000 balance at 6.25% with 25 years remaining may have a scheduled payment near $1,847. Adding $200 monthly plus a $5,000 one-time payment can reduce the balance faster and save interest.
The payoff path depends on how the loan servicer applies extra money. Some borrowers prefer steady monthly extras, while others use bonuses or tax refunds as lump-sum principal payments.
If extra payments shorten payoff by several years, the savings come from avoiding years of interest charges on a lower balance.
