What DSCR is, and why it decides your loan

Debt service coverage ratio answers one question a credit committee cannot skip: does this business produce enough cash to make the payments? The formula is simple — net operating income ÷ annual debt service — but the inputs are where applications succeed or die. Underwriters rebuild both sides from your tax returns, your year-to-date statements, and your debt schedule. If those three don't agree, the ratio you calculated at home is not the ratio in the credit memo.

The income side

Start with net income, then add back interest, depreciation, and amortization. Owner compensation above market, one-time legal costs, and non-recurring equipment expense can be added back too — but only when the books document them clearly enough for a lender to accept.

The debt side

Twelve months of principal and interest on every obligation: term notes, lines of credit drawn, equipment leases, SBA loans, and the proposed new payment. Cards and seller notes count. Debt omitted from your schedule and found in the returns costs you credibility.

The thresholds

1.25x is the working standard for bank and SBA 7(a) credit. Commercial real estate runs 1.20x to 1.35x by property type. Contractors and other cyclical borrowers are often held to 1.35x or higher because revenue is lumpy.

What moves the number

Refinancing a five-year note to ten years cuts annual debt service sharply. Retiring a high-payment line helps immediately. So does correcting misclassified expenses that understate real profit — a common finding in books that were never reconciled.

A ratio above 1.25x only helps if the statements behind it hold up. That is what our loan-ready financials service in Houston produces: lender-format P&L and balance sheet, a complete debt schedule, and a DSCR calculation documented the way a credit memo shows it. If the history has to be rebuilt first, start with catch-up bookkeeping and QuickBooks cleanup, then read the SBA loan bookkeeping guide for the full document list.

DSCR questions we get from Houston borrowers

What is DSCR?

Debt service coverage ratio (DSCR) is your net operating income divided by your total annual debt payments — principal plus interest. A DSCR of 1.25x means the business generates $1.25 of income for every $1.00 of debt service, leaving a 25% cushion.

What DSCR do lenders require?

Most Houston banks and SBA 7(a) lenders underwrite to a minimum of 1.25x. Commercial real estate often needs 1.20x to 1.35x depending on property type, and asset-heavy or cyclical borrowers such as contractors are frequently held to 1.35x or higher.

How is DSCR calculated?

DSCR = net operating income ÷ annual debt service. Net operating income is typically net income plus interest, depreciation, amortization, and documented one-time or owner add-backs. Annual debt service is twelve months of principal and interest on existing debt plus the proposed new loan.

What is a good DSCR?

Above 1.25x is generally approvable, 1.50x and above is strong, 1.00x to 1.24x is tight and usually requires more collateral or a guarantor, and below 1.00x means the business does not currently cover its debt payments.

Can I improve my DSCR before applying?

Yes. Documenting legitimate add-backs, refinancing short-amortization debt into longer terms, retiring high-payment credit lines, and cleaning up misclassified expenses that overstate costs all move the ratio. Clean books are what let a lender accept those adjustments.
