How to Calculate Your DSCR Before Applying for a Business Loan

DSCR is the single number that determines whether a bank will approve your loan. Most business owners don’t know theirs before they apply.

Debt Service Coverage Ratio — DSCR — is how banks measure whether your business generates enough cash flow to cover a new loan payment, on top of everything it already owes. It’s not a credit score. It’s not revenue. It’s a ratio that tells a lender one thing: if we give you this loan, can you actually pay it back?

Understanding your DSCR before you apply does three things. It tells you whether you’re ready. It tells you how much you can realistically borrow. And it tells you exactly what to work on if the number isn’t where it needs to be.

The DSCR Formula

The formula is straightforward:

DSCR = Net Operating Income ÷ Total Debt Service

Where:

• Net Operating Income (NOI) = your business’s earnings before interest, taxes, depreciation, and amortization
• Total Debt Service = all principal and interest payments you make over a given period — including the new loan you’re applying for

A DSCR of 1.0 means your income exactly covers your debt payments — no cushion. A DSCR of 1.25 means you have 25% more income than debt obligations. Most banks require 1.25 as a minimum. Below 1.0 means you’re already cash-flow negative on paper.

Step 1: Calculate Your Net Operating Income

Start with your most recent full year of business financials. You’re looking for your net operating income — revenue minus operating expenses, before debt payments, depreciation, taxes, and owner draws.

Take your gross revenue and subtract:

• Cost of Goods Sold (COGS)
• Operating expenses (rent, payroll, utilities, marketing, etc.)

Do NOT subtract:

• Loan payments or interest
• Depreciation (non-cash expense)
• Owner draws above a reasonable market salary
• One-time non-recurring expenses

Example:

• Annual Gross Revenue: $800,000
• COGS: $320,000
• Operating Expenses: $280,000
• Net Operating Income: $200,000

Note: Experienced lenders will often add back depreciation, amortization, and owner compensation above a market-rate salary to get a more accurate picture of true cash flow. This is called “adjusted NOI” or “cash flow available for debt service.”

Step 2: Calculate Your Total Debt Service

This is where many business owners underestimate their DSCR — because they forget to include everything.

Total Debt Service = all annual payments across every business obligation:

• Existing bank loans (annual principal + interest)
• Lines of credit (minimum annual payments)
• Equipment leases (annual payments)
• MCA positions (daily or weekly payment × 52 or 365 to annualize)
• Any other recurring financial obligations
• The proposed new loan payment

Example continued:

• Existing term loan: $24,000/year
• Equipment lease: $12,000/year
• Active MCA (annualized): $36,000/year
• Proposed new loan payment: $30,000/year
• Total Annual Debt Service: $102,000

Step 3: Run the Ratio

Divide your NOI by your Total Debt Service:

$200,000 ÷ $102,000 = 1.96

A DSCR of 1.96 is strong — well above the 1.25 minimum most banks require. Now see what happens if that MCA were higher — $72,000 annualized instead of $36,000:

$200,000 ÷ $138,000 = 1.45

Still above 1.25, but the cushion has narrowed significantly. Add one more obligation, and you’re approaching the line.

What DSCR Thresholds Actually Mean

Below 1.0 — Cash-flow negative. Rarely approved by any traditional lender.
1.0 – 1.15 — Very tight. Most banks will decline or require significant collateral.
1.15 – 1.24 — Below standard minimum. SBA and bank loans unlikely without compensating factors.
1.25 – 1.49 — Meets minimum. Approval possible, terms may be conservative.
1.50 – 1.99 — Comfortable. Good approval prospects with competitive terms.
2.0+ — Strong. Lenders compete for this business. Best terms available.

Why Your DSCR Might Be Lower Than You Think

MCA payments are the most common hidden drag. A single MCA with daily payments of $500 equals $182,500 annualized. That alone can devastate an otherwise healthy DSCR. Lenders find these in your bank statements even if you don’t list them on your debt schedule.

Owner draws above market salary reduce NOI. If you’re paying yourself $300,000 from a business where market-rate compensation would be $120,000, lenders may add back $180,000 — but you can’t count on this. Some lenders do it; others don’t.

Seasonal businesses need to be careful about which period they use. Lenders use trailing 12 months. So should you, to get an accurate picture.

Depreciation reduces net income on tax returns but not on cash flow. If your depreciation is significant, your true cash DSCR is higher than your tax-return DSCR — worth understanding and discussing with your lender.

How to Improve Your DSCR Before Applying

Increase NOI:

• Grow revenue
• Cut unnecessary operating expenses
• Delay large discretionary spending until after your application

Decrease Debt Service:

• Pay off or down existing loan balances before applying
• Eliminate MCA positions — this is usually the highest-impact move
• Apply for a smaller loan amount (lower proposed payment)
• Extend the loan term you’re requesting (lower annual payment)

Apply for the right amount: A smaller loan means a smaller annual payment, which means a higher DSCR. If you’re borderline, asking for $150,000 instead of $200,000 may be the difference between approval and denial.

DSCR for Commercial Real Estate Loans

CRE lenders calculate DSCR differently. Instead of business operating income, they use the property’s Net Operating Income — rental income minus operating expenses — divided by the annual mortgage payment. Most CRE lenders require a minimum DSCR of 1.20 to 1.25, depending on property type and market.

Calculate It Before They Do

Banks will run your DSCR with or without you. The difference is whether you’ve had time to improve it, explain it, or choose a loan structure that works with your current number.

Running the calculation yourself — honestly, with all obligations included — takes about 20 minutes and tells you more about your loan readiness than any credit score check.

If your DSCR is above 1.25, you’re likely in range for bank and SBA products. If it’s below, you know exactly what to fix — and by how much.
