Why DSCR matters for small businesses

Lenders, investors, and owners use DSCR to judge whether a business generates enough cash to meet debt obligations. A healthy DSCR improves your chances of getting favorable loan terms and reduces the risk of covenant breaches that can trigger penalties or accelerated repayment. In my 15 years advising small businesses, I’ve seen DSCR act as the difference between landing a growth loan and being forced into costly short-term financing.

How to calculate DSCR (step-by-step)

Use this basic formula:

DSCR = Net Operating Income (NOI) / Total Debt Service

Where:

  • Net Operating Income (NOI): cash earnings available to pay debt. Lenders often start with operating income and make adjustments for non-cash charges (depreciation), owner compensation, and recurring add-backs. Some lenders use EBITDA or modified EBITDA; others prefer cash flow from operations on tax returns. (See lender-specific guidance.)
  • Total Debt Service: the sum of principal and interest payments due in the coming 12 months on all business debt.

Example:

  • NOI (adjusted cash flow): $200,000
  • Annual debt service (principal + interest): $150,000
  • DSCR = 200,000 / 150,000 = 1.33

A DSCR of 1.33 means the business generates 1.33 times the cash needed for debt payments.

What counts as income and debt to lenders?

Lenders may adjust both numerator and denominator:

  • Common NOI adjustments: add-backs for owner salary reductions, one-time expenses, non-cash depreciation, and certain favorable recurring items. Some lenders will normalize seasonal businesses by annualizing peak months.
  • Common debt service inclusions: business loan payments, equipment financing, lines of credit with scheduled payments, and sometimes guaranteed personal liabilities pledged to the business.

Because practices vary, always ask the lender how they calculate DSCR. The same company can show different DSCRs to different lenders depending on adjustments.

Typical DSCR thresholds and what they mean

  • Less than 1.0: Insufficient cash to cover debt — high risk of default.
  • 1.0 to 1.25: Marginal — may get smaller loans or higher rates; lenders often want reserves or stronger covenants.
  • 1.25 to 1.5: Generally acceptable for many small business loans and favorable for negotiation.
  • Above 1.5: Strong — can access larger loans, better rates, and more flexible terms.

These thresholds are general; industry norms and the borrower’s credit profile affect lender expectations. For example, volatile sectors like hospitality or construction often need higher DSCR cushions to account for seasonality.

How lenders use DSCR in underwriting and covenants

Lenders use DSCR to set loan size, pricing, and covenants. A loan agreement may require the borrower to maintain a minimum DSCR each quarter or year. If your DSCR falls below the covenant, you could face higher interest, additional collateral requirements, or default. Lenders also use stress-testing to see how DSCR reacts to revenue drops (see our guide on stress testing cash flow: “Stress Testing a Borrower’s Cash Flow: What Lenders Do and Why”).

Common lender adjustments and red flags

  • Aggressive add-backs: Lenders scrutinize repeatable vs. non-repeatable add-backs. One-time legal settlements are not repeatable cash.
  • Ignoring owner draws: Lenders may reduce NOI if owner compensation is inconsistent with the business size.
  • Short-term IO (interest-only) deals: These can show an artificially high DSCR during the IO period but may worsen once principal payments begin.

Always document adjustments with bank statements, tax returns, and profit-and-loss statements.

Practical strategies to improve DSCR

  1. Increase recurring revenue
  • Focus on predictable income streams (subscriptions, service contracts) to smooth seasonality.
  1. Reduce controllable expenses
  • Review vendor contracts, renegotiate lease terms, and cut non-essential costs.
  1. Refinance or restructure debt
  • Lengthening amortization lowers annual debt service and improves DSCR, but be aware it increases total interest paid over the loan life.
  1. Build a debt service reserve
  • Set aside 3–6 months of debt payments in a dedicated account to reassure lenders and satisfy covenant requirements.
  1. Use short-term working capital strategically
  • Avoid permanently rolling operating deficits into long-term debt; temporary lines to cover seasonality are better backed by cash flow plans.
  1. Improve margins
  • Increase prices where market allows, reduce COGS, and eliminate low-margin customers.

In my practice, a simple reserve and a 90-day plan to increase repeatable sales often move a borderline DSCR from 1.0 to 1.3 within a business quarter.

How often to monitor DSCR

Monitor DSCR quarterly at minimum. Businesses with high seasonality should measure it monthly and model a 12-month rolling DSCR to anticipate covenant breaches. Use scenario modeling: what happens if revenue drops 10–25%?

Common misconceptions

  • Mistake: “High revenue equals strong DSCR.” Reality: Revenue without positive cash flow or with heavy seasonal swings may still leave DSCR low.
  • Mistake: “Taxable income equals NOI.” Reality: Tax returns include non-cash and timing items. Lenders adjust taxable income to arrive at lender NOI or cash flow.

Reducing lender friction when applying for loans

  • Prepare reconciled financial statements and a short add-back schedule explaining each adjustment.
  • Provide 12–24 months of bank statements and a cash-flow forecast showing how new financing will be repaid.
  • Ask prospective lenders how they calculate DSCR and whether they allow specific add-backs.

When DSCR isn’t the only metric

Lenders look at many things beyond DSCR: credit history, collateral, liquidity, loan-to-value, and industry risk. For commercial real estate, lenders often compute a property-level DSCR using Net Operating Income specific to the asset.
