SBA Collateral Adequacy Calculator
Lenders don't count your assets at what you paid. See what your collateral is worth to the underwriter and whether your personal real estate comes into play.
SOP 50 10 8.1 (effective Oct 1, 2026) sets exact discount rates for collateral: improved real estate at ≤85% of market value minus prior liens (unimproved land 50%), new machinery & equipment at ≤75% of price, used at ≤50% of net book value (≤80% with a liquidation appraisal), and furniture, fixtures, and trading assets at just 10%. On a business purchase the lien on receivables and inventory is mandatory. If the discounted total falls short of the loan, the lender must look to the personal real estate of 20%+ owners, but a shortfall alone is never grounds to decline the loan.

Value Your Collateral the Way the Lender Will
Enter what the business (and the deal) brings to the table. Leave anything you don't have at 0.
Benchmark (SOP 50 10 8.1 collateral discount rates): improved real estate counts at up to 85% of market value minus prior liens (unimproved land 50%), new equipment at 75% of price, used equipment at 50% of net book value (or 80% of an orderly-liquidation appraisal), furniture & fixtures at 10%, and inventory/receivables at 10% (lien mandatory on a purchase). Inadequate collateral alone is not a reason to decline. Source: SBA SOP 50 10 8.1, Appendix 15 and Appendix 19.
Counts at 75% of price. Excludes furniture & fixtures.
Counts at 10%.
Count at 10%. On a business purchase, SBA SOP 50 10 8.1 requires the lender to take a lien on these.

The "Will the SBA Fund This Deal?" kit checks your whole deal the way an underwriter will walk-away price, equity injection, collateral adequacy, global DSCR, and the red flags that kill applications verified against the current SOP 50 10 8.1.

The discounts approximate what a lender would actually recover selling the assets in a default. Used equipment sells for roughly half its book value; used furniture and fixtures for almost nothing (hence 10%); inventory and receivables shrink fast once a business stops operating.
This is why deals that "have plenty of assets" still come up short on the fully-secured test, the assets are real, but the lender counts them at liquidation math, not purchase price. Even owned real estate is haircut: under SOP 50 10 8.1 a $1,000,000 building with a $400,000 mortgage counts as $450,000 (85% of value minus the lien), not its $600,000 of equity. Acquisitions are hit hardest: most of the purchase price is goodwill, which counts for nothing at all.
What a shortfall actually triggers (and doesn't)
A shortfall does not decline the loan, SOP 50 10 8.1 (Appendix 19) is explicit: a loan request "must not be declined solely because collateral is inadequate." It triggers the personal real estate rule: the lender must take available equity in real estate solely owned by 20%+ owners, co-borrowers, and guarantors (homes, plus investment and other commercial property), with the lien limitable to the shortfall amount, and not required at all when your equity is under 25% of the property's value.
Knowing your shortfall number before you apply means you can negotiate it, more seller-held assets in the deal, a lien limited to the gap, or simply walking into the meeting knowing exactly what the lender will ask for and why.

Frequently Asked Questions
What does "fully secured" mean for an SBA loan?
Under SOP 50 10 8.1 (effective Oct 1, 2026), a loan is fully secured when the lender holds security interests in available fixed assets whose combined adjusted value reaches the loan amount. "Adjusted" is the key word: improved real estate counts at up to 85% of market value minus prior liens (unimproved land at 50%), new machinery and equipment at up to 75% of price, used equipment at up to 50% of net book value (or up to 80% with an orderly liquidation appraisal), and furniture, fixtures, and trading assets at only 10%. On a business purchase the lender must also take a lien on the accounts receivable and inventory, counted at no more than 10% of current book value.
Will my SBA loan be declined if I don't have enough collateral?
No, this is one of the most misunderstood SBA rules. SOP 50 10 8.1 (Appendix 19) says a loan request "must not be declined solely because collateral is inadequate"; the SBA guaranty exists for borrowers who can repay but can't fully secure the loan. What a shortfall does trigger: the lender must take available equity in personal real estate (including investment and other commercial property) solely owned by owners of 20% or more, co-borrowers, and guarantors, and the lien may be limited to the shortfall amount.
Why does used equipment only count at 50% of book value?
Because that's roughly what a lender recovers selling used equipment in a default. The SOP caps used machinery and equipment at 50% of net book value unless an independent orderly liquidation appraisal supports up to 80% of the appraised liquidation value. Furniture and fixtures fare worse, 10%, because used office and shop fittings have almost no resale market.
Will the lender put a lien on my house?
Only if the loan is not fully secured by business assets. Then the lender is required to take available equity in personal real estate solely owned by 20%+ owners, co-borrowers, and guarantors, but the lien may be limited to the shortfall amount (or to 150% of the equity), it sits behind your existing mortgage, and it matters only in a default. And if your equity in the property is less than 25% of its fair market value, the lender isn't required to lien it at all.
