What is DSCR?

Debt Service Coverage Ratio is one of the most critical metrics in commercial lending. It determines whether a business generates enough income to comfortably cover its debt payments — and whether a lender will approve your deal.

The DSCR Formula
DSCR = Net Operating Income ÷ Total Annual Debt Service. A ratio of 1.0x means income exactly covers payments. Most SBA lenders require 1.25x, meaning $1.25 of income for every $1.00 in debt. A higher DSCR gives lenders confidence and often results in better rates and terms.
What Counts as NOI
Net Operating Income is revenue minus operating expenses, before interest, taxes, depreciation, and amortization. Lenders will scrutinize your NOI carefully and may exclude one-time income or add back above-market owner compensation.
What Counts as Debt Service
Debt service includes all principal and interest payments on existing loans plus the proposed new loan. Many buyers underestimate this by forgetting existing obligations. Lenders will pull a full debt schedule and include everything.
Why 1.25x is the Floor
The 1.25x minimum provides a cushion. If your business hits a rough quarter, 1.25x DSCR means you still have 25% headroom before payments can't be covered. Below 1.25x, the risk is unacceptable to most lenders.
How to Improve Your DSCR
Three levers: increase NOI (revenue or margin improvement), reduce the loan amount (larger down payment), or extend the loan term to lower annual debt service. Seller financing on standby can also improve DSCR in the eyes of most SBA lenders.
DSCR vs. LTV
DSCR measures cash flow adequacy; LTV measures collateral coverage. A deal can have strong LTV but weak DSCR. For business acquisitions, SBA lenders prioritize DSCR — the cash flow has to work regardless of what the assets are worth.

DSCR FAQ

Most SBA lenders require a minimum 1.25x DSCR. Some will consider 1.15x–1.20x with compensating factors like strong personal credit, a large down payment, or significant collateral. A 1.50x+ DSCR is considered strong and typically gets the best terms.

It depends on the loan purpose. For business acquisitions, DSCR is calculated on the target business's NOI. For commercial real estate loans, it's the property's NOI. For owner-occupied real estate used in the business, lenders often blend both.

Options include: putting more money down to reduce the loan amount, negotiating a longer term to lower annual debt service, asking the seller to carry back a portion on standby, or addressing operational issues suppressing NOI. Strong compensating factors can sometimes get you over the line below 1.25x.

Lenders primarily use 2–3 years of historical NOI from tax returns. Projections are generally not accepted alone. However, a clear growth trajectory backed by contracts or verifiable trends may be considered as a supplement to strong historical performance.

A higher DSCR signals lower risk, which can translate to better pricing. A 1.50x+ DSCR often qualifies for the best available rates. A borderline 1.20x–1.25x may result in a higher rate or additional loan conditions.
