"Debt service" simply means the payments required to stay current on your obligations. It is central to how financing is evaluated.
The basic idea
Debt service is the total of principal and interest payments due over a period. Lenders look at how comfortably your cash flow covers it, because that coverage signals whether new financing is sustainable.
Why coverage matters
The more cushion between your cash flow and your required payments, the more resilient your business is to a slow month. Thin coverage leaves less margin for surprises.
Using it in decisions
Before taking on new financing, it helps to consider how the added payment fits alongside existing obligations, not just on its own.
The formula
DSCR = Net operating income ÷ Total annual debt serviceDebt service means principal plus interest for the year, across every obligation.Reading the number
| DSCR | What it indicates |
|---|---|
| Below 1.00× | Cash flow does not currently cover debt service. |
| 1.00–1.19× | Coverage is thin; little room for a slow period. |
| 1.20–1.39× | Commonly viewed as workable coverage. |
| 1.40× and above | Comfortable coverage relative to obligations. |
Thresholds vary by lender, structure, and industry. The point is the arithmetic: adding a payment raises the denominator, so coverage falls unless income rises with it.
- Retiring or consolidating a high-frequency obligation
- Extending amortization so the annual payment falls
- Documenting add-backs that legitimately belong in operating income
- Timing the request after a strong, verifiable revenue period
