How DSCR Affects Whether Your Deal Gets Funded

🔧 Tool: Debt Service Calculator

Your model can be perfect and your deal can still die for one reason: DSCR does not clear.

Lenders do not finance your optimism. They finance cash flow.

That is why DSCR matters. It is the gate. If you miss it, the bank either cuts the loan size or declines the deal. Either way, your purchase price and equity check change immediately.

What DSCR actually is

The version lenders use, not the version in your spreadsheet

At its simplest:

• DSCR = Operating cash flow ("OCF") ÷ Debt service ("DS")

For SBA underwriting, OCF is generally defined as EBITDA, with permitted additions and subtractions under SBA rules. Debt service is the future required principal and interest payments on business debt, including the new SBA loan.

That definition matters because many buyers model DSCR using a more conservative "owner free cash flow" approach (EBITDA less CapEx, less taxes, less working capital investment). That is a good way to run your own risk analysis. It is not always how the lender is going to calculate the ratio.

You want both views:

1. Lender DSCR (what gets the deal approved)

2. Owner cash flow (what keeps you alive post-close)

The thresholds (and why you still need cushion)

Minimums are not targets

SBA guidance for Standard 7(a) loans requires DSCR of at least 1.15:1 (OCF divided by DS). For 7(a) Small Loans, lenders have more flexibility under streamlined underwriting, but most still target similar coverage levels.[^1]

In practice, lenders want more than the bare minimum. A 1.25:1 DSCR is the practical floor for most banks making acquisition loans. Even when the SBA minimum is met, banks will look at (i) business volatility, (ii) customer concentration, (iii) working capital needs, and (iv) your ability to absorb surprises.

Practical takeaway: a deal that underwrites at exactly the minimum is fragile. Underwriting is done on paper. Operations happen in real life.

Why your DSCR changes after LOI

Because seller EBITDA is marketing material

The seller's adjusted EBITDA is an opening offer. It is not a bankable number.

Banks and QoE providers haircut:

• aggressive add-backs

• "one-time" expenses that keep happening

• under-reserved owner comp and benefits

• related-party rent that is off market

• deferred maintenance that is really recurring

This is where buyers get trapped. They sign an LOI at a price that only works if every add-back survives. Then diligence produces a real cash flow number. DSCR drops. Financing shrinks. Now you are negotiating from a weaker position because you are already committed on paper and already deep in diligence costs.

I have seen this play out as a slow-motion deal death: the bank does not say "no" up front, they just keep asking for more equity until the buyer either cannot (or should not) write the check.

How to model DSCR before LOI

Three cases, one decision

Before you sign an LOI, run three DSCR cases:

1. Ceiling case: seller adjusted EBITDA as presented

2. Probable case: a haircut on the weakest add-backs (often 10% to 20% of the adjustment stack)

3. Downside case: a heavier haircut that reflects "we got sold a story"

Then run the same debt service assumptions you expect the lender to use (rate, term, amortization). If the probable case does not clear DSCR comfortably, your offer price is too high for the leverage you want.

A simple rule of thumb on valuation sensitivity: at a 4x multiple, every $100K change in sustainable EBITDA moves value by $400K. If your add-back stack has $200K of "maybe," you are not debating $200K. You are debating $800K of price.

What to do when DSCR breaks

Fix the structure, not just the spreadsheet

If DSCR does not clear, you have real levers:

• Price: reduce purchase price to match fundable cash flow

• Equity: increase equity to reduce debt service

• Seller note: use seller financing (often on standby for SBA) to reduce senior debt burden

• Terms: a longer amortization or better rate can help (if available), but do not count on it saving a marginal deal

• Deal scope: carve out non-earning assets or unprofitable lines that drag coverage down

If the only way the deal works is "hit the plan immediately," the deal is not structured for survival.

What's Next

Before LOI, do this in order:

1. Rebuild EBITDA from the seller financials and list every add-back.

2. Create a haircut case and assume your QoE rejects the weakest items.

3. Size your loan to the haircut case, not the ceiling case.

Use the Debt Service Calculator

Model DSCR under different rates, terms, and EBITDA haircuts. Use it before LOI so you know the maximum debt your deal can support. Output: annual debt service and DSCR by scenario.

[^1]: Important note on upcoming changes: Effective March 1, 2026, SBA will sunset the mandatory SBSS credit score prescreening for 7(a) Small Loans (Procedural Notice 5000-875701). Currently, Small Loan applications must pass an SBSS score threshold (raised to 165 in June 2025) before streamlined processing. After March 2026, lenders will have discretion to use their own credit evaluation methods for these loans. This does not change DSCR requirements, but it does change how lenders evaluate creditworthiness for deals under $350K. If you are pursuing a Small Loan, ask your lender how they plan to underwrite post-sunset—some may tighten other criteria (including DSCR expectations) to compensate for losing the standardized credit screen.
