How Do You Calculate Global Cash Flow for a Commercial Loan?
Global cash flow asks whether a business and its owners, together, can carry all of their debt. The formula, a simple example, and the borrower situations where it changes the credit decision.
Global cash flow combines the cash flow of a borrowing business with the personal cash flow of its owners and guarantors and any related entities, counting each dollar once, then compares the total with their combined debt service. Global DSCR equals that combined cash available divided by all business, personal and related-entity debt service.
What Is Global Cash Flow Analysis?
For many commercial borrowers, especially closely held businesses and real estate entities, the business and its owners are financially intertwined. Owners draw distributions, guarantee loans, own other entities and carry personal debt. Looking at the business alone can overstate or understate true repayment capacity.
Global analysis asks the question a guarantor’s signature implies: if the business stumbles, can the owners and their other holdings carry the debt? And are the owners’ personal obligations quietly depending on the business’s cash? It applies to owner-occupied real estate, investment property and C&I loans alike.
How Is Global Cash Flow Calculated?
Start with the business’s cash flow available for debt service, add the guarantors’ recurring personal cash flow after personal taxes and living expenses, and add or subtract related entities, counting each dollar once. Divide by the combined debt service of everyone included.
In formula form, global DSCR equals combined cash available for debt service divided by all business, personal and related-entity debt service. Bank regulators do not set a global DSCR minimum, though SBA 7(a) loans carry a program DSCR minimum. Bank policies commonly fall between about 1.10x and 1.25x, often below the standalone requirement.
The formula is simple. The judgment is in the inputs: which income is recurring, what the owners really owe in taxes, and which entities to include and at what share.
Global Cash Flow Example: Calculating Global DSCR
An S corporation produces $500,000 of cash flow available for debt service against $300,000 of business debt service. Its sole owner has $150,000 of other recurring cash income, owes $165,000 of personal taxes, including tax on the owner’s share of the business’s taxable income, and has $60,000 of living expenses and $40,000 of personal debt service. Global DSCR is $425,000 divided by $340,000, or 1.25x.
Note what is missing: the owner’s K-1 income and distributions from this business. Because the business’s cash flow is already counted, adding either would count the same dollars twice. And note what is included: personal tax on the business’s income, which the owner owes whether or not the cash was distributed.
| Line | Amount |
|---|---|
| Business cash flow available for debt service | $500,000 |
| Owner’s other recurring cash income | $150,000 |
| Less personal taxes, including tax on business income | ($165,000) |
| Less living expenses | ($60,000) |
| Global cash available for debt service | $425,000 |
| Business debt service | $300,000 |
| Personal debt service | $40,000 |
| Global debt service | $340,000 |
| Global DSCR | 1.25x |
When Does Global Cash Flow Matter Most?
Whenever the business and its owners are financially intertwined: the owners guarantee the loan, draw large distributions, own other entities or carry significant personal debt. In those cases the business alone can overstate, or understate, the real capacity to repay.
These situations are common in community bank lending, which is why global cash flow is a routine part of underwriting guaranteed commercial credits at many banks.
| Situation | Why the business alone is not enough |
|---|---|
| Owner-occupied real estate | The property entity’s rent income is the operating company’s rent expense, so neither can be judged alone |
| S corporation or partnership borrower | Owners owe personal tax on business income whether or not it was distributed |
| Guarantor with several businesses | Losses or capital calls elsewhere can pull cash away from the borrower |
| Real estate investor with many LLCs | The property in this request may cover its loan while others in the portfolio, or the owner, do not |
| Guarantor of other debt | Contingent liabilities can become real ones in a downturn |
| Owner with heavy personal debt | Personal obligations may depend on distributions from the business |
What Are Common Global Cash Flow Mistakes?
The most common error is counting the same dollars twice: adding the owner’s K-1 income or distributions from a business whose cash flow is already in the analysis. Others include missing guarantees of other entities’ debt, relying on a stale personal financial statement, and living expense assumptions with no basis.
Each one distorts the coverage ratio, and each is easier to catch with practice on real guarantor files than from a checklist.
From Global Cash Flow to a Credit Decision
A global DSCR is only as good as the judgment behind its inputs. The skill is knowing which entities and income to include, reading the guarantor’s tax returns for what they really say, and deciding how much support a guarantor actually provides.
Shockproof teaches it on real guarantor files. CRE Loan Underwriting teaches borrower, guarantor and global debt service analysis as one repeatable procedure, and C&I Loan Underwriting covers reading a guarantor’s personal tax returns and weighing their real liquid support.

What is the difference between DSCR and global DSCR?
DSCR measures a single borrower’s cash flow against its own debt service. Global DSCR combines the cash flow of the business, its guarantors and related entities, counting each dollar once, and compares it with all of their combined debt service.
Do you use K-1 income or distributions in global cash flow?
For the borrowing business, and any entity consolidated into the analysis, use neither: its cash flow is already counted, so adding the owner’s K-1 income or distributions counts the same dollars twice. For a related entity that is not consolidated, count the cash distributions the owner actually received, not the taxable K-1 share.
Which related entities belong in global cash flow?
Include related entities whose cash flow or debt affects the guarantor: in proportion to ownership, or at 100% when the guarantor controls the entity or guarantees its debt. Say which approach you used in the write-up.
How do you treat debt a guarantor has guaranteed for another entity?
Include either that entity’s cash flow and debt service together, or only the shortfall it needs from the guarantor. Counting the full payment without the entity’s cash flow overstates the burden; leaving it out understates it.
What is a good global debt service coverage ratio?
Bank regulators do not set a minimum, though SBA 7(a) loans carry a program DSCR minimum. Bank policies commonly fall between about 1.10x and 1.25x, often below the standalone DSCR requirement, depending on loan type, collateral and guarantor strength.
