Before a lender prices or approves business debt, it computes the debt service coverage ratio: net operating income divided by total debt service — principal and interest on all obligations, often including the new loan being sized. It answers the lender's only real question: after the business pays its costs, is there enough left to pay this debt, with a cushion? A DSCR of 1.0 is break-even; most commercial lenders want roughly 1.25 times or better, meaning 25 percent more cash flow than the payments require. Orer News publishes information, not financial advice.
The ratio is also the most useful number you can compute before applying — it predicts both the approval decision and the maximum loan the arithmetic supports.
How is DSCR computed?
Numerator: net operating income — revenue minus operating expenses, before interest, taxes, depreciation, and amortization, and critically before any owner compensation adjustments the lender will add back only if documented. Denominator: all scheduled debt payments — existing loans, leases, the proposed loan, and sometimes personal debt the guarantor carries if the file requires global cash-flow analysis. Real estate and investment-property lending uses the same ratio on property NOI, with published minimums common around 1.20 to 1.25 for investment mortgages. Small-business lenders vary, but the arithmetic never does.
What moves the ratio — and the loan?
Because the proposed payment sits in the denominator, DSCR effectively caps loan size: at a given income, the payment that keeps the ratio above threshold defines the maximum amortizing amount, and lenders size offers from exactly that arithmetic — which is why a requested amount sometimes comes back smaller with a longer term attached. Owners can move the numerator honestly: documented add-backs for one-time expenses, non-recurring costs, depreciation — legitimate adjustments, each requiring proof. And the denominator can be restructured: extending amortization, consolidating small high-payment balances, or paying off consumer debt held personally improves coverage immediately.
What do lenders read into a weak DSCR?
A ratio between 1.0 and 1.2 signals a business that services debt only in good months — lenders respond with higher pricing, shorter terms, more collateral, or a smaller loan. Below 1.0, the proposal is a projection rather than a repayment plan, and approval depends on the story compensating: contracts signed, a tenant's lease, a documented history of growth. The honest self-assessment before applying: compute the ratio on trailing twelve-month actuals, not projections; a projected 1.4 that is a historical 0.9 is a decline with extra steps.
How do you improve it before applying?
Timing: apply on your strongest quarter's trailing numbers, since seasonal troughs deflate the ratio. Housekeeping: document every legitimate add-back with invoices and tax returns, because undocumented adjustments are ignored. Structure: request the term length the asset actually supports — longer amortization lowers the payment and lifts coverage. Debt hygiene: clear or consolidate small balances with disproportionate payments. And bookkeeping: lender-quality financials — clean accrual statements reconciled to tax returns — let the ratio be computed on your best facts rather than discounted for mess.
- DSCR = net operating income ÷ all debt payments
- Target roughly 1.25×; below 1.2 gets repriced
- The ratio caps loan size — longer terms lift coverage
- Compute on trailing actuals with documented add-backs
You will never see a box for it on the application, but the ratio decides the file. Computing it first — honestly, on real numbers — turns the loan conversation from an audition into an arithmetic review you already passed.
