Global DSCR: The Second Calculation SBA Lenders Run That Most Business Owners Don't Know About
You've done your homework. You've calculated your DSCR, confirmed the business generates $1.28 for every dollar of debt service, and scheduled the meeting with your SBA lender.
The lender runs their own numbers. They come back with questions about your personal finances.
This surprises most business owners because they've never heard of global DSCR. It's the second calculation SBA lenders run after they look at your business — and it factors in your personal debt obligations alongside your business cash flow. A business that clears the 1.25 threshold on its own can still create problems in underwriting if the owner's personal financial picture tells a different story.
What Global DSCR Measures
Business DSCR answers one question: can the company pay its loans from operating income?
Global DSCR asks a broader question: when you combine the business's cash flow with everything the owner personally owes, does the picture still hold?
The calculation pools together:
- Business net operating income (with approved add-backs)
- Owner's salary or draw from the business
- Any other personal income sources
Then it divides that by:
- All business debt service (including the new SBA loan)
- The owner's personal debt obligations: mortgage or rent, car payments, student loans, personal credit lines, any other fixed monthly payments
Global DSCR = (Business NOI + Personal Income) / (Business Debt Service + Personal Debt Service)
Most SBA lenders want to see a global DSCR of at least 1.0 to 1.15. Some require 1.25 globally, same as the business threshold. The floor varies by lender, but the calculation itself is nearly universal.
Why Lenders Care About Your Personal Debt
The logic is straightforward. Your business may generate plenty of cash, but if you're pulling a $175,000 salary to cover a heavy personal balance sheet — mortgage, two car payments, private school tuition — the lender is looking at where that money is going.
If your business hits a rough quarter and you cut your draw, can your household absorb that? Or does a softer month for the business create an immediate personal financial problem, which then creates pressure on how you manage the business?
The global DSCR isn't a judgment on how you live. It's an underwriting tool that looks at the full picture, because business and personal finances are not actually separate for most small business owners. The SBA knows this. So do the lenders.
A Worked Example
A landscaping company owner applies for a $350,000 SBA 7(a) loan.
Business side:
| Line Item | Amount |
|---|---|
| Net income (tax return) | $94,000 |
| Owner's salary | $85,000 |
| Depreciation add-back | $22,000 |
| Interest add-back | $7,500 |
| Business NOI | $208,500 |
| New SBA loan (annual) | $53,400 |
| Existing equipment loan | $14,800 |
| Total business debt service | $68,200 |
Business DSCR: $208,500 / $68,200 = 3.06
That clears the threshold easily. But the lender also asks for a personal financial statement.
Personal side:
| Line Item | Monthly | Annual |
|---|---|---|
| Mortgage | $3,100 | $37,200 |
| Truck payment | $680 | $8,160 |
| Spouse's car payment | $490 | $5,880 |
| Student loan | $410 | $4,920 |
| Total personal debt service | — | $56,160 |
Global DSCR calculation:
- Total income: $208,500 NOI + owner's $85,000 salary drawn = $293,500
- Total debt service: $68,200 business + $56,160 personal = $124,360
- Global DSCR: $293,500 / $124,360 = 2.36
This still clears the threshold with room to spare. But change the numbers slightly — owner's draw is lower, personal debt is heavier — and a business with strong operating metrics can run into a global DSCR problem.
When Global DSCR Gets Tight
The most common scenario is a business owner who pays themselves modestly but carries significant personal debt. The business might be profitable and efficient, but if the owner's household is heavily leveraged, the global calculation can drop below the lender's floor even when the business DSCR looks fine.
A few situations where this shows up frequently:
Recent home purchase. A new mortgage at 2026 rates is a bigger monthly number than many borrowers expected. If you bought a house in the last 12-24 months, your global debt service is higher than it was the last time anyone reviewed your personal finances.
Multiple vehicles or equipment financed personally. Business owners sometimes finance trucks, trailers, or other equipment under their personal credit rather than the business. That debt counts in the global calculation.
Spouse's debt not excluded. Some lenders include the spouse's personal debt obligations in the global DSCR. Others only include the business owner's. Know which approach your lender uses before you submit the personal financial statement.
Two businesses, one owner. If you own multiple entities and pull income from more than one, lenders want the full picture across all of them.
What to Do Before You Apply
Run your global DSCR yourself before a lender does it for you. The inputs you need:
- Your business NOI with add-backs (the same number you'd use for business DSCR)
- Your actual salary or draw from the business
- Any other income sources you'd report on a personal financial statement
- Every fixed personal debt obligation: mortgage/rent, car loans, student loans, personal lines of credit
If your global DSCR is below 1.15, you have a few options before applying:
Pay down personal debt. A smaller personal balance sheet improves the global calculation. If you have cash reserves, paying off a car loan or personal credit line before applying changes the denominator meaningfully.
Document other income. Rental income, a working spouse's income, or other documented personal income sources can be added to the numerator. Make sure the income is documented — lenders want tax returns or bank statements, not projections.
Reduce the requested loan amount. A smaller SBA loan means lower annual debt service on the business side, which improves both ratios. If your global DSCR is close to the floor, borrowing slightly less might be the cleaner path than trying to restructure your personal balance sheet.
Time the application. If you have a large personal debt that will be paid off in 6-9 months, waiting until it's gone improves your global profile. A lender sees a snapshot; a slightly later snapshot might be a cleaner one.
The Move Before the Meeting
Pull up your personal financial statement before your lender asks for it. Calculate the global DSCR number yourself. If it's below 1.15, you now have time to address it — either by reducing personal debt, documenting additional income, or adjusting the loan structure.
Most business owners who get surprised by global DSCR questions in underwriting could have seen the issue coming if they'd run the calculation in advance. The lender will run it either way. Better to run it yourself first.
Use the KnowYourNut DSCR Calculator to calculate your business DSCR with real inputs before you apply. Combine that number with your personal financial picture and you'll walk into any lender meeting knowing your number from both angles.
