What Is DSCR? How Banks Calculate Debt Service Coverage

The basic formula

DSCR = Cash flow available for debt service ÷ Annual debt service

For operating businesses, banks commonly start with EBITDA (earnings before interest, taxes, depreciation and amortization) from your tax returns, then adjust it. Annual debt service is the total of all scheduled principal and interest payments over the next twelve months, including the proposed new loan.

A worked example

This is a hypothetical example to illustrate the math, not a quote.

Hypothetical DSCR calculation
Line item	Amount
Net income (from tax return)	$300,000
+ Interest expense	$40,000
+ Depreciation and amortization	$110,000
= EBITDA	$450,000
− Distributions to owners (if the bank deducts them)	($80,000)
− Unfinanced capital expenditures	($20,000)
Cash flow available for debt service	$350,000
Existing annual debt service	$120,000
Proposed new loan annual payment	$150,000
Total annual debt service	$270,000
DSCR	$350,000 ÷ $270,000 = 1.30x

At 1.30x, this hypothetical borrower would clear a typical 1.20x–1.25x bank minimum.

Common adjustments (add-backs and deductions)

Banks differ in how they adjust cash flow, which is one reason the same business can get different answers from different banks.

Typically added back: interest on debt being refinanced, depreciation, amortization, and documented one-time, non-recurring expenses.
Sometimes added back: excess owner compensation above a market salary, rent paid to a related property entity that the bank also analyzes.
Typically deducted: owner distributions (especially to pay pass-through taxes for S corporations and LLCs), unfinanced capital spending, and sometimes taxes.

Documentation matters: an add-back you cannot support with records usually will not be accepted.

Global DSCR

For closely held businesses, many banks calculate a global DSCR that combines the business with the guarantors’ personal income and personal debt obligations (mortgage, car loans, credit cards) and any affiliated entities such as a property LLC. A business with strong coverage can still fall short on a global basis if owners carry heavy personal debt, and the reverse can also be true.

Typical DSCR expectations

General DSCR expectations (vary by bank)
Loan type	Commonly cited minimum
C&I term loans and lines	About 1.20x–1.25x
Owner-occupied commercial real estate	About 1.20x–1.25x on operating cash flow
Investment real estate	Often 1.25x or higher on net operating income
SBA 7(a)	SBA requires repayment ability from cash flow; lenders commonly look for 1.15x–1.25x or more

DSCR as a loan covenant

Many loan agreements include a minimum DSCR covenant tested annually (sometimes quarterly) on your financial statements. Falling below it can be a default even if every payment is current. Understand exactly how the covenant is defined, because the covenant formula may differ from the underwriting formula.

How to improve your DSCR

Extend the amortization. A longer repayment term lowers the annual payment.
Refinance expensive short-term debt, such as merchant cash advances, into longer-term bank debt.
Document one-time expenses so the bank can add them back.
Use the most recent results if the trend is improving; banks often consider interim or trailing-twelve-month figures.
Reduce or time owner distributions thoughtfully.
Add equity to reduce the loan amount.

DSCR vs. other ratios banks use

Common bank credit ratios
Ratio	Formula	What it shows
DSCR	Cash flow ÷ debt service	Ability to make payments
Debt to tangible net worth	Total liabilities ÷ (equity − intangibles)	Leverage
Senior debt to EBITDA	Funded debt ÷ EBITDA	How many years of earnings the debt represents
Current ratio	Current assets ÷ current liabilities	Short-term liquidity
Loan to value (LTV)	Loan amount ÷ collateral value	Collateral cushion

DSCR for real estate vs. operating businesses

For investment real estate, DSCR uses the property’s net operating income (rent minus operating expenses) instead of EBITDA. For owner-occupied real estate and C&I loans, banks use the operating company’s cash flow. Mixing these up is a common source of confusion when comparing quotes. See our owner-occupied CRE guide.

Common mistakes

Using projected rather than historical cash flow.
Forgetting existing debt, equipment leases or personal debt in global coverage.
Assuming every bank adds back owner compensation or distributions the same way.
Leaving one-time expenses undocumented, so the bank cannot add them back.

Key takeaways

DSCR = cash flow available for debt service ÷ annual debt service.
Most banks typically want 1.20x–1.25x or more.
Banks also test global DSCR including guarantors.
Longer amortization, documented add-backs and refinancing costly debt can improve the ratio.

Frequently asked questions

What is a good DSCR for a business loan?

Most banks typically look for at least about 1.20x–1.25x. Higher coverage generally means a stronger application.

Is DSCR calculated before or after owner distributions?

It depends on the bank. Many deduct distributions, especially those used to pay owners' pass-through taxes. This is a common source of differences between banks.

What is global DSCR?

A combined coverage ratio that includes the business, its guarantors' personal income and debts, and affiliated entities.

Does DSCR use tax returns or internal financials?

Banks primarily rely on tax returns for historical years and may use interim internal financials for the current year.

What happens if my DSCR is below 1.0x?

Cash flow does not cover debt payments, and most banks will decline unless there is a strong, documented reason the shortfall is temporary or other repayment sources are clear.

Is DSCR the same as interest coverage?

No. Interest coverage compares earnings to interest only; DSCR includes principal payments, so it is a stricter test.

Does a new loan's payment count in DSCR?

Yes. Banks typically calculate pro forma DSCR including the proposed loan's annual principal and interest along with all existing debt service.

Which years do banks use for DSCR?

Most review the last two to three fiscal years and the current interim period, paying attention to the trend and the most recent full year.

Can a strong balance sheet offset a low DSCR?

Sometimes partially. Significant liquidity or collateral can support a request, but banks generally still require cash flow to be the primary repayment source.
