DSCR for business loans: build the ratio, then interrogate the assumptions
Understand debt-service coverage ratio, numerator choices, annual debt obligations, add-backs, projections, sensitivity tests, and why lenders calculate it differently.
For an owner preparing for cash-flow or commercial real-estate underwriting.
Quick answer
Quick answer
Debt-service coverage compares a measure of cash available for debt service with required debt payments. A result above 1.00 indicates the selected cash-flow measure exceeds the selected debt service; it does not guarantee approval.
Begin with the idea, not a universal formula

Different products and lenders can define the numerator and denominator differently. Ask for the exact calculation used in your transaction rather than applying one internet formula as law.
Reconcile the numerator
For a business, underwriting may begin with net income and consider documented non-cash items, owner compensation, one-time expenses, taxes, distributions, affiliate activity, and other adjustments. For income-producing real estate, analysis commonly focuses on net operating income.
Every add-back should have a reason, evidence, and a view on whether it will recur. An expense does not become cash merely because it is inconvenient.
Build complete annual debt service
Include principal and interest on existing obligations, the proposed obligation, equipment debt, lines that amortize, and other required payments under the lender’s method. Normalize daily, weekly, and monthly payments to the same annual period without losing their timing risk.
A debt schedule is the bridge between accounting statements and this denominator. Reconcile balances and payments to statements and payoff letters.
Stress the ratio instead of polishing it
Recalculate with a revenue decline, margin compression, a rate reset, loss of a customer, higher rent, or delayed opening. For variable-rate debt, model payment changes. For a project, separate historical coverage from projected coverage and document the ramp.
The useful output is not one ratio. It is the point where coverage breaks and the operational response available before that point.
Plain answers
01What DSCR do lenders require?
There is no universal threshold. Product, lender policy, cash-flow volatility, collateral, term, industry, and the calculation itself matter.
02Is EBITDA the same as cash available for debt service?
Not automatically. Lenders may adjust income and expenses differently and include taxes, distributions, capital needs, or other obligations.
03Can projected income be used?
It may be considered in some transactions, but assumptions, support, historical performance, and lender policy matter. Ask how projections are weighted.
