Commercial Loan Refinance Calculator

The current outstanding principal balance of your existing mortgage — not the original loan amount, but how much you currently owe. Get the exact payoff amount from your lender, which may differ slightly from your last statement due to accrued interest.

Your existing monthly principal + interest (P&I) payment only. Do not include property taxes, insurance, or escrow amounts. You can find this on your mortgage statement or by calling your lender.

The annual interest rate on your existing loan. You'll find this on your original loan documents, your most recent mortgage statement, or by calling your servicer.

The annual interest rate you expect to receive on the refinanced loan. This should be based on a real quote from a lender, not an estimate. Even a 0.5% rate reduction can save significant interest over a 30-year term.

Use the rate tables on this site to find current commercial mortgage rates.

The number of years (amortization term) of your new refinanced loan. Refinancing to a longer term lowers your monthly payment but increases total interest paid. Refinancing to a shorter term increases your payment but reduces total interest cost.

All fees required to complete the refinance: lender origination fees, appraisal, title insurance, legal/recording fees, and any prepayment penalty on the existing loan. Enter 0 to see pure interest savings without cost impact.

The calculator shows how many months it takes to recoup closing costs through monthly payment savings — this is your break-even point.
