Commercial Mortgage Calculator 2026: What Will My Commercial Mortgage Payment Be? ★★★★★

How This Commercial Mortgage Calculator Answers "What Will My Payment Be?"

The most common question for commercial real estate investors is "what will my commercial mortgage payment be?" Our commercial mortgage calculator 2026 provides the answer instantly using standard commercial loan formulas. With over 50,000 monthly users, it's the most trusted tool for commercial real estate investors in America. Commercial mortgages differ from residential mortgages in several key ways: they typically have balloon payments because the loan term is shorter than the amortization period (e.g., 25-year amortization but only 5-10 year term), they are often interest-only for initial periods, and they require DSCR (Debt Service Coverage Ratio) analysis.

Commercial Mortgage Payment Formula Explained

The standard P&I (Principal & Interest) payment formula for commercial loans is: Payment = L × [r(1+r)^n] ÷ [(1+r)^n - 1], where L = loan amount, r = monthly interest rate, n = total months in amortization period. For interest-only loans, the formula is simply Payment = L × r (monthly interest only). Balloon payment is calculated by amortizing the loan over the full period (25-30 years) but only making payments for the actual term (5-10 years). The remaining balance after the term period is the balloon payment due at maturity.

Understanding DSCR (Debt Service Coverage Ratio)

DSCR = Net Operating Income (NOI) ÷ Annual Debt Service. This is the most important metric for commercial loan qualification. Minimum DSCR requirements: 1.20x for most banks, 1.25x for CMBS, 1.15x for SBA, 1.15-1.20x for Fannie/Freddie. A DSCR of 1.25x means the property generates 25% more income than needed to cover the mortgage payment. Higher DSCR = better loan terms, lower rates, and higher leverage. If DSCR is below 1.0x, the property is cash flow negative and will not qualify for conventional financing without additional equity or guarantees.

Balloon Payment Strategies & Exit Planning

Balloon payments are the biggest risk in commercial real estate financing. Options to handle a balloon payment include: refinance with a new lender (most common), sell the property before maturity, pay down the balance using cash reserves, negotiate an extension with your current lender, or partially pay down and refinance the remainder. Plan your exit strategy 12-24 months before the balloon date. Interest rates may be higher at maturity, property values may decline, and credit markets may tighten — always have a backup plan. Our calculator shows exactly what your balloon payment will be so you can plan accordingly.
