It estimates how much sooner a fixed-rate mortgage can be paid off, and how much interest that could avoid. You can test a lower rate while keeping the current principal-and-interest payment, or keep the rate and add extra principal each month.
A lower rate reduces the interest due each month. If you still pay the old principal-and-interest amount, the difference goes to principal. The balance falls faster, so the loan can end before the original term. Financed fees raise the balance and can use up part of that advantage.
Yes. The IRRRL funding fee is 0.50% of the loan amount unless the borrower is exempt. This calculator can roll that fee, and closing costs you enter, into the new balance. Net savings subtract those costs from the interest reduction. An exemption is a planning toggle here, not a VA determination.
Yes. Use the extra-principal option. It keeps the current rate and adds the amount you choose to each payment. Confirm with your servicer that extra funds are applied to principal rather than held for a future installment.
No. If the new rate is higher, or if financed costs raise the balance enough that the old payment barely covers interest, the term can stay the same or get longer. If the payment does not cover interest at all, the calculator stops and explains that the loan would not pay off on that path.
No. Results are educational estimates of principal and interest. They are not a commitment to lend, a locked rate, a Loan Estimate, or a decision that a VA IRRRL meets net tangible benefit or seasoning rules. Taxes, insurance, and lender overlays are not included.
