Commercial Loan Calculator: DSCR & Payment

Commercial sizing hinges on the property’s net operating income and the lender’s required DSCR.

MBReviewed by Mike Basti, Mortgage Broker & Founder · NMLS #377740
Quick Answer

DSCR = net operating income ÷ annual debt service. Lenders often require 1.20–1.25+. The loan is sized so the property’s income comfortably covers the payment, then capped by LTV.

How the loan is sized

Lenders take the property’s net operating income (NOI) and divide by the required DSCR to find the maximum supportable payment — then back into a loan amount, capped by LTV (often 65–75%).

Example

NOI of $120,000 with a required DSCR of 1.25 supports $96,000/yr in debt service. The loan amount that fits that payment (given rate and amortization), up to the LTV cap, is your likely maximum. We’ll model it precisely.
