DSCR Explained: The Number Behind Your Deal

On most commercial and rental files, one number does a lot of the deciding: the DSCR, or debt service coverage ratio. It tells a lender whether the property's income can carry the financing. Understand it and you understand how your deal will be read. Here is the plain-language version.

What Goes Into It

Net Operating Income

NOI: the property's income after operating costs, before financing.

Annual Debt Service

A full year of mortgage payments, principal and interest.

The Ratio

NOI divided by debt service. Above 1.0 means income covers the payments.

The Cushion

Lenders usually want income above the payments by a margin, not just barely covering.

The Quick Math

DSCR = net operating income divided by annual financing payments.

Illustrative example: a property nets $120,000 a year and the financing costs $100,000 a year, so the DSCR is 1.2. Income covers the payments with a 20 percent cushion. The higher the number, the more comfortable the lender. Figures are illustrative only.

How to Strengthen It

Raise the income

Better occupancy, market rents at renewal, or trimming operating costs lift NOI.

Ease the payment

More equity, a longer amortization (the years to repay), or a different structure can lower annual debt service.

Bring a clean file

Clear financials and leases let a lender credit the income you actually have.

If the property's income carries the payments with room to spare, the deal gets easier. We will run your numbers and tell you where the DSCR lands before you go to a lender. See also How Commercial Financing Works. Any figures or ratios are illustrative only.
