Franchise Debt Service Coverage Ratio: How Much Headroom Unit Four Needs

A lender approving your fourth franchise unit is mostly underwriting your first three. Franchise debt service coverage ratio (DSCR) is the annual cash flow your business has available for debt payments divided by the principal and interest due that year on all business debt. For 7(a) Small Loans approved on or after March 1, 2026, SBA's Procedural Notice 5000-876777 sets the minimum at 1.10 to 1, and the number that matters more is how far your existing units can slip before you reach it.

What does a franchise debt service coverage ratio include?

It includes cash flow from every business that stands behind the loan, divided by payments on every business debt, including the new one. SBA's notice defines debt service as the future required principal and interest payments on all business debt, inclusive of the new SBA loan, and tells lenders to weigh the effect any affiliates have on repayment.

For a multi-unit operator, the denominator holds the equipment note on unit two, the SBA loan that built unit three and the line of credit that covers payroll timing, not only the loan for unit four. The numerator is the part lenders define differently. Some start from EBITDA and subtract owner compensation, taxes and unfunded capital spending, and some do not. Ask which version your lender uses before running any number, because the same operator can show a materially different ratio under each.

Why unit four is underwritten on units one through three

A new unit has no operating history, so its projections carry the least weight in the file. The same notice says a ratio can be shown on a historical or a projected basis, and when projections are used the applicant must demonstrate 1.10 to 1 or better within one year of loan funding. That is a short window for a unit still in its ramp period, which often earns less in year one than it will later.

So the cash flow that clears the ratio usually comes from units that are already open. It is the same pressure behind the working capital shortfall that catches new franchisees: the opening year costs more and earns less than the plan says, and existing units cover the difference. The useful question is how much room they have to do it.

A worked example: the same loan for two operators

Take two operators who each own three units and want a $340,000, ten-year loan for unit four. All figures here are hypothetical. SBA lists a maximum maturity of ten years for equipment and for working capital loans. Assume a rate of 9.87 percent, which is the 6.87 percent average bank prime loan rate for September 2026 from the Federal Reserve's H.15 release plus three points. The rate is an assumption for the example, and your lender sets the real one.

At that rate the payment is $4,468.68 a month, or $53,624 a year. Both operators already pay $310,000 a year on existing debt, so total debt service becomes $310,000 plus $53,624, or $363,624. Operator A earns $540,000 a year in cash flow before debt service across the three open units, a current ratio of 540,000 divided by 310,000, or 1.74. Operator B earns $387,500, a current ratio of 1.25.

Assume unit four contributes $20,000 in its first year. Operator A then shows 560,000 divided by 363,624, or 1.54. Operator B shows 407,500 divided by 363,624, or 1.12. Both clear 1.10 on paper, with the same loan, the same unit and the same projection.

How far can existing units slip before coverage hits 1.10?

Multiply total debt service by 1.10, subtract the new unit's year-one contribution, and compare the result with what existing units earn today. Here, $363,624 times 1.10 is $399,987. After the new unit's $20,000, the three existing units must still produce $379,987 a year. The gap between today's cash flow and that figure is your headroom.

Operator A can lose $160,013 of existing cash flow, a 29.6 percent decline, before reaching 1.10. Operator B can lose $7,513, or 1.9 percent. A 10 percent dip in existing cash flow leaves A at 1.39 and B at 1.01, below the floor. A 20 percent dip leaves A at 1.24 and B at 0.91. The approval-day ratios of 1.54 and 1.12 both pass, but only one of them survives an ordinary bad year, such as a wage increase or a soft quarter at two locations.

A three-test scorecard to run before you sign the lease

Run these tests with the new payment included. The thresholds are yours to set, and the lender's may differ.

Test 1 is day-one coverage. Set the new unit's contribution to zero and divide existing cash flow by total debt service. Operator A gets 540,000 divided by 363,624, or 1.49. Operator B gets 1.07, which is below 1.10 before the unit has opened.

Test 2 is headroom, calculated as above. Choose a tolerance in advance, for example the ability to absorb a 15 percent decline in existing cash flow, and treat anything below it as a reason to resize the deal rather than a reason to revise the forecast.

Test 3 is year-three coverage. Replace the year-one contribution with the unit's steady-state projection, say $110,000. Operator A reaches 1.79 and Operator B reaches 1.37, but B only gets there if the unit hits plan, which is the assumption the first two tests are built to avoid depending on. The inputs for Test 3 can come from a four-number unit economics scorecard.

What to ask the lender before the term sheet

Four questions settle most of the ambiguity. Which definition of cash flow does the lender use, and does it deduct owner compensation and taxes? Are your other LLCs pooled into the calculation, given that SBA's notice tells lenders to consider affiliates? Does the lender size the loan on a historical ratio or a projected one, and what happens at the one-year mark if it is projected? And does the loan carry a personal guarantee, because a ratio with no headroom turns a business downturn into personal exposure?

The numerator in all of this goes stale if it lives in a spreadsheet updated at tax time. Revscale's FranFinance connects to QuickBooks, pulls financial data from every location daily and compares each location's cost categories with similar locations, so an operator has a current cash flow figure to rerun these tests against before the next lending conversation.

Before the lease for unit four is signed, rebuild your franchise debt service coverage ratio with the new payment included and the new unit set to zero. If existing units cannot absorb the decline you chose in advance, the options are a smaller loan, more equity or a later opening date, and each is cheaper to change now than after the first soft quarter.
