Refinance & Payoff Calculators

Weigh a refinance against your current loan, time discount points, and see how extra payments erase interest.

About these calculators

A refinance only pays off when the monthly saving outruns the closing costs before you sell or refinance again. These calculators find that break-even point, weigh discount points, and compare a cash-out or rate-and-term refinance against the loan you already have.

On the payoff side, see how extra monthly payments, a lump-sum recast or a biweekly schedule shorten the term and cut total interest. Each tool turns a vague ‘should I?’ into a dated, dollar answer.

Common questions

Refinance & Payoff calculators — frequently asked

When is it worth it to refinance?

When the monthly saving recovers the closing costs before you sell or refinance again — the break-even point. A meaningful rate drop, a shorter term, or removing FHA insurance are the common triggers; a tiny rate cut rarely justifies the costs.

How do I pay off my mortgage faster?

Add extra to principal each month, switch to biweekly payments, or make a lump-sum payment or recast — each cuts the term and total interest, since interest is charged on the remaining balance. The payoff calculators show the new date and the savings.

What is a cash-out refinance?

It replaces your mortgage with a larger one and hands you the difference in cash, at today’s rate on the whole balance.

It works best when today’s rate is at or below your current one; otherwise a home equity loan is often cheaper.

Does refinancing hurt your credit?

Only slightly and briefly. The lender’s hard credit pull and the new account dip your score a few points, an effect that fades within months and is usually outweighed by the savings a good refinance delivers.
