How Banks Calculate How Much You Can Borrow: Understanding DSCR

What is DSCR for a business loan?

The debt service coverage ratio compares cash flow available for debt payments with the principal and interest due over the same period. In plain English: for every dollar you owe in loan payments, how much does your business have available to pay it?

• 1.00x: cash flow just covers the debt payments, with no cushion in this calculation.
• 1.25x: the business generates $1.25 for every $1 of debt service.
• Below 1.00x: the cash flow being measured is not enough to cover the debt payments.

The numerator is not simply revenue or the balance in your checking account. A lender may start with EBITDA—earnings before interest, taxes, depreciation, and amortization—and make adjustments. Definitions vary, so ask which cash-flow measure the bank uses. [1]

A simple DSCR calculation

Suppose a lender determines that your business has $150,000 in annual cash flow available for debt service. Your existing loans require $60,000 per year, and the proposed loan would add another $60,000 in annual payments.

Annual cash flow used by the lender

$150,000

Existing annual debt payments

$60,000

Proposed annual debt payments

$60,000

Total annual debt service

$120,000

DSCR: $150,000 ÷ $120,000

1.25x

That leaves $30,000 after the debt payments in this simplified calculation. It is not necessarily spare cash: taxes, equipment replacement, working-capital needs, and other obligations may still affect the lender’s analysis.

What DSCR do banks look for?

There is no single minimum that applies to every business loan. Chase explains that banks often look for at least 1.25x, giving the business some room for unexpected expenses or weaker results. That is a useful planning benchmark, not a universal approval rule. [2]

The actual requirement depends on the lender, loan program, industry, financial history, and how cash flow is calculated. Do not assume a ratio quoted for an SBA loan, a commercial property, or another borrower applies to your application. A strong DSCR also does not replace credit, collateral, eligibility, or documentation requirements.

How much business loan can I get?

DSCR can help estimate the payment your business might support. Start with the lender’s cash-flow figure, divide it by the required ratio, then subtract the payments on debts that will remain after closing.

1. Find total payment capacity. With $150,000 in annual cash flow and an assumed 1.25x requirement: $150,000 ÷ 1.25 = $120,000 in total annual debt service.
2. Subtract existing obligations. If existing debt payments are $60,000 per year, the simplified capacity for a new loan is $60,000 annually.
3. Convert to a monthly payment. $60,000 ÷ 12 = $5,000 per month for the proposed loan.
4. Test a loan amount. Use the interest rate and repayment term to see what principal amount fits that payment.

At an illustrative fixed annual interest rate of 10%, a $5,000 monthly payment supports approximately $235,000 over five years, or $378,000 over ten years, assuming monthly amortization and no fees. These are hypothetical examples, not current rates, available offers, or an approval estimate. Longer terms reduce payments for the same principal but generally increase total interest paid.

Try your own amounts in the business loan calculator. It estimates payments; it does not determine your lender-approved cash flow or borrowing limit.

Which expenses can be added back?

Accounting profit and cash available to repay a loan are not always the same. Depreciation and amortization are common non-cash adjustments. A lender may also consider a documented expense that genuinely will not recur. None of this means every expense can simply be erased from the calculation. [1]

• Document the adjustment. Keep invoices, financial statements, and a clear explanation of why a cost is nonrecurring.
• Do not double-count. If depreciation or interest is already excluded in EBITDA, adding it back again inflates cash flow.
• Be realistic about owner expenses. Owner pay is not automatically available for loan payments if the business needs that work performed or the household depends on it.
• Remember ongoing cash needs. Equipment replacement and inventory growth can consume cash even when reported earnings look healthy.

Ask your accountant to prepare a reconciliation and let the lender confirm which adjustments it accepts.

Why strong revenue can still mean a small loan

A business with $2 million in sales does not necessarily have more borrowing capacity than one with $1 million. Thin margins, existing payments, seasonal dips, or cash tied up in receivables can change the picture. DSCR focuses on repayment capacity—not how impressive the sales number looks.

Also, a full year can hide a difficult month. A bank may review interim statements, prior years, projections, and obligations beyond the business alone. A line of credit can require a different payment assumption than a term loan, so do not assume today’s interest-only payment is the figure the bank will use. Our term loan vs. line of credit guide explains how the products differ.

How to strengthen your application

• Prepare current financial statements, tax returns, bank statements, and a complete business debt schedule.
• Separate recurring earnings from unusual events, and explain any difference between reported profit and cash flow.
• Improve collections, control avoidable costs, and address weak margins rather than relying only on higher sales.
• Consider a smaller request, more equity, or a repayment structure suited to the investment. Confirm available terms with the lender.
• If refinancing, identify which debts will be paid off so the analysis reflects the proposed post-closing obligations.
