How to calculate DSCR

DSCR = net operating income ÷ total annual debt service

Net operating income

Revenue minus operating expenses, before interest and taxes. Many lenders use EBITDA, and some adjust it for owner compensation.

Total annual debt service

All principal and interest payments due on business debt over the year, including the proposed new loan.

Example: a business has net operating income of $180,000 and pays $12,000 a month ($144,000 a year) on its loans. Its DSCR is $180,000 ÷ $144,000 = 1.25.

What DSCR do lenders require?

How much can your business borrow?

Divide your net operating income by the lender’s minimum DSCR to find the maximum annual debt service you can support. With $180,000 of net operating income and a 1.25 minimum, the maximum is $144,000 a year in total loan payments, or $12,000 a month.
