What Is DSCR and Why Every Business Buyer Needs to Know It
The single number that decides whether your lender says yes — and how to use it to your advantage before you ever step into a bank.
Before your lender looks at your credit score, your industry experience, or even the business itself, they'll calculate one number: DSCR. If it's below their threshold, the deal is dead — no matter how good everything else looks. If it's strong, it becomes your most powerful negotiating tool. Here's everything you need to know.
What DSCR Actually Means
DSCR stands for Debt Service Coverage Ratio. It's a measure of how much cash flow a business generates relative to what it costs to service the debt used to buy it.
The formula is simple:
DSCR = Net Operating Income ÷ Annual Debt Service
Where:
- Net Operating Income (NOI) is the business's EBITDA or SDE (Seller's Discretionary Earnings) — essentially the cash a business produces before the owner takes a salary
- Annual Debt Service is the total principal + interest payments on your acquisition loan for the year
A DSCR of 1.0 means the business generates exactly enough cash to cover the loan payments — nothing left over. A DSCR of 1.25 means for every $1.00 owed, the business generates $1.25 — a 25% buffer.
Most SBA lenders require a minimum DSCR of 1.25. Some conventional lenders require 1.35 or higher. Anything below 1.0 is a hard no from virtually every institutional lender.
A Real Example
Say you're looking at a landscaping business with $180,000 in SDE. You're considering an SBA 7(a) loan at 7.5% interest over 10 years for $800,000.
Annual debt service on that loan works out to roughly $115,000/year.
DSCR = $180,000 ÷ $115,000 = 1.56
That's a comfortable deal. The business generates $1.56 for every $1.00 owed — well above the 1.25 threshold. Your lender will likely approve this without issue.
Now say the seller is asking $1,100,000 instead. The same loan at $1,100,000 produces annual debt service of about $158,000.
DSCR = $180,000 ÷ $158,000 = 1.14
Below 1.25. You'd need to either renegotiate the price, put in more cash down to reduce the loan size, or find seller financing to bridge the gap.

Why Lenders Care So Much
Lenders aren't betting on the best-case scenario. They're stress-testing for the realistic downside. If revenue dips 10% after the ownership transition — which is common — does the business still cover its debt? The 1.25 cushion is their answer to that question.
For SBA loans, the DSCR calculation typically looks at the last 2-3 years of tax returns, not just the trailing twelve months. Sellers who've had one standout year need to demonstrate consistency.
Some lenders will also factor in your personal income, existing debts, and the proposed owner's salary when running DSCR — especially if you plan to replace an owner who was paying themselves below market.
How to Use DSCR Before You Make an Offer
Most buyers wait for the lender to calculate DSCR. Smart buyers run it themselves first — because it tells you immediately whether a deal can be financed, and at what price.
Here's the process:
1. Get the seller's SDE from the listing or CIM (Confidential Information Memorandum)
2. Estimate the loan amount (asking price minus your down payment)
3. Calculate annual debt service using current SBA rates (check the SBA's current maximum rate)
4. Divide SDE by annual debt service
5. If DSCR is below 1.25, back-calculate what price would get you there
This gives you a data-driven ceiling on your offer before negotiations begin. Instead of anchoring on the asking price and working backward, you anchor on the financing and work forward.
What Can Hurt Your DSCR
- ›Owner salary above what you plan to pay yourself (sellers sometimes inflate this)
- ›Add-backs that lenders won't accept (one-time "non-recurring" expenses that actually recur)
- ›Existing business debt that carries over post-acquisition
- ›Lease obligations not reflected in SDE
- ›High capex requirements the business has deferred
- ›Revenue concentration in one or two clients (lenders may haircut revenue by 15-25%)
DSCR After the Deal Closes
DSCR doesn't stop mattering once you own the business. SBA loans often include covenants that require you to maintain a minimum DSCR (usually 1.15 or 1.25) throughout the loan term. If you fall below it, your lender can call the loan or restrict your ability to take distributions.
Monitor it quarterly. A sustained dip in revenue is a signal to act — cut costs, adjust pricing, or open a conversation with your lender before a covenant breach, not after.
