What is collateral in a business loan?

Collateral is an asset (or pool of assets) that a borrower pledges to a lender as security for a loan. If the borrower defaults, the lender has a legal claim — called a security interest — to seize and sell the collateral to recover the outstanding debt. Collateral doesn't eliminate underwriting scrutiny, but it can improve loan terms (lower rate, higher loan amount) and help borderline applicants qualify.

Common Business Collateral Types

• Commercial real estate: Owner-occupied or investment property. Lenders typically advance 65–80% of appraised value (loan-to-value). Most secure form of collateral — liquid in most markets.
• Equipment and machinery: Advance rates typically 75–85% of fair market value (FMV) for new equipment, lower for used. Equipment loans often self-collateralize — the financed machine is the collateral.
• Accounts receivable (AR): Advance rates typically 70–90% of eligible AR (invoices under 90 days, no concentration over 20–25% with one debtor). AR is the primary collateral for invoice factoring and ABL revolvers.
• Inventory: Advance rates typically 40–60% of cost value — heavily discounted because inventory varies in liquidation value. Food, fashion, and seasonal inventory receive lower advance rates.
• Cash and CDs: 100% advance rate (cash is cash). Certificate of deposit pledged as collateral is essentially a cash-secured loan — lowest rate possible.
• Vehicles and rolling stock: 70–85% of book value for commercial vehicles; depreciates faster than real estate.
• Intellectual property: Rarely used as standalone collateral — patents, trademarks, and copyrights are difficult to value and liquidate. Sometimes included in a blanket lien on all business assets.

How Lenders Value Collateral

Lenders apply advance rates — a discount to market or appraised value — to account for the costs and uncertainty of liquidation. A lender advancing 75% on equipment worth $200,000 is lending $150,000 against that asset. If the borrower defaults and the equipment sells for $160,000 at auction, the lender recovers the loan plus costs with margin to spare. The advance rate is a risk cushion, not an appraisal of the asset's actual worth.

Perfecting a Security Interest

Pledging collateral is not enough — the lender must 'perfect' the security interest to establish legal priority over other creditors. For personal property (equipment, inventory, AR), perfection happens by filing a UCC-1 financing statement with the state Secretary of State. For real estate, the lender records a mortgage or deed of trust in the county recorder's office. For vehicles, a lien is noted on the title. Without perfection, the lender's security interest may be subordinate to other creditors' claims in bankruptcy.

SBA Collateral Policy

Under SBA SOP 50 10, lenders are required to collateralize SBA loans to the maximum extent possible — but insufficient collateral alone is not grounds to decline an otherwise creditworthy loan. This is a significant policy distinction: the SBA does not require full collateral coverage as a condition of guaranty. Lenders must take available business assets plus personal real estate with equity, but cannot decline a creditworthy applicant solely because business assets are insufficient.
