Definition
Debt service coverage compares the cash a business generates with the loan repayments it must make, including both interest and capital. It is usually expressed as a ratio (DSCR): cash available for debt service divided by annual debt service. A ratio of 1.0 means the business earns exactly enough to meet its repayments, with nothing to spare. Lenders usually set a minimum ratio before they will lend.
Worked example
A fictional buyer is acquiring Crestview Auto Repair, a fictional US business with SDE of $500,000. A market salary for the owner's role is $100,000, which leaves $400,000 available to service debt. To keep the example simple, it ignores tax and capital spending.
The purchase is funded partly with a loan costing $250,000 a year in interest and capital repayments.
DSCR = $400,000 divided by $250,000 = 1.6 times.
If earnings fell by a quarter, to $300,000, coverage would drop to 1.2 times.
Seller's discretionary earnings (SDE)
Seller's discretionary earnings is the yearly financial benefit a business gives one full-time working owner, before financing costs, non-cash charges and one-off spending.
Why buyers care
Coverage shows how much room the business has to absorb a bad year before you struggle to meet repayments. A deal that works on paper at the asking price can fail once you add debt and pay yourself a proper salary.
Test coverage on realistic earnings, not the seller's best year, and try a weaker case as well. In buyer mode, Loupe's valuation tool includes an affordability check: enter your deposit, seller finance, interest rate and loan term, and it shows the loan amount, annual debt service, coverage against a minimum threshold and a simple payback period. Lenders calculate coverage in their own ways, often after tax and capital spending, so confirm the method with yours.
The asking price is the price a seller or broker puts on a business when it is listed. It is an opening position, not a valuation, and what it includes varies from listing to listing.
Seller finance is when the seller lends the buyer part of the purchase price, to be repaid with interest after completion. It is also called vendor finance or a seller note.
