Borrowing Base Facility Explained: Formula, Collateral and Example
A borrowing base facility is a revolving credit line where availability is recalculated against eligible collateral, usually accounts receivable, inventory, commodities, equipment or other current assets. The borrower can draw only up to the lender-approved borrowing base, not simply the headline facility size.
Request a QuoteBorrowing base facilities are common in asset-based lending, commodity finance, receivables finance and inventory-backed working capital lines. The lender does not just ask, “Can the borrower repay?” It asks, “What collateral exists today, how liquid is it, how controlled is it, and what percentage can be advanced safely?”
For technical market context, see Bank of America’s asset-based lending overview and the Secured Finance Network’s borrowing base discussion. Financely also covers related structures in Asset Based Lending and Borrowing Base Facility in Commodity Trading.
Basic Borrowing Base Formula
The formula changes by lender, sector, collateral type and jurisdiction, but the basic logic is simple.
Simple Borrowing Base Example
| Collateral Category | Gross Amount | Eligibility Adjustment | Advance Rate | Availability |
|---|---|---|---|---|
| Accounts receivable | $5,000,000 | $4,000,000 eligible after aged debt, disputes and concentration exclusions | 80% | $3,200,000 |
| Inventory | $3,000,000 | $2,000,000 eligible after slow-moving stock and obsolete stock exclusions | 50% | $1,000,000 |
| Reserves | Not applicable | Rent reserve, duty reserve, dilution reserve and professional fee reserve | Not applicable | -$300,000 |
| Total availability | Maximum draw under the borrowing base | $3,900,000 | ||
Core Components of a Borrowing Base Facility
Eligible Receivables
Receivables that meet the lender’s criteria: current, enforceable, undisputed, from approved account debtors and free from competing liens.
Eligible Inventory
Inventory that is saleable, insured, controlled, appraised and not obsolete, consigned, work-in-progress or subject to title uncertainty.
Availability Reserves
Lender deductions for dilution, customer concentration, rent, unpaid taxes, customs duties, field exam concerns or collateral uncertainty.
What Makes Collateral Ineligible?
| Collateral Type | Common Ineligibility Triggers |
|---|---|
| Receivables | Aged beyond 90 days, disputed, cross-aged, affiliate receivables, contra accounts, foreign debtors, concentration breaches, government receivables without assignment approval. |
| Inventory | Obsolete goods, slow-moving stock, work-in-progress, consigned inventory, goods in transit without control, bonded goods without release mechanics, uninspected commodities. |
| Commodities | Unhedged price exposure, weak warehouse receipts, unclear title, no collateral manager, insufficient insurance, unacceptable storage location, no inspection certificate. |
| Equipment | No appraisal, no serial-number register, weak resale value, title issues, poor maintenance, high relocation cost or specialized equipment with limited buyer market. |
Financely view: most weak borrowing base requests fail because the borrower presents revenue, not collateral. Lenders need an AR ageing, inventory schedule, lien search, customer concentration report, proof of delivery, insurance evidence, borrowing base certificate, cash dominion plan and reporting cadence.
Borrowing Base Certificate
A borrowing base certificate is the recurring report that tells the lender how much collateral is eligible and how much can be drawn. It usually includes receivables, inventory, reserves, existing loan balance, excess availability and covenant compliance. In serious ABL facilities, this is not a casual spreadsheet. It is a controlled credit document.

Request a QuoteFrequently Asked Questions
What is a borrowing base facility?
A borrowing base facility is a revolving credit line where the borrower’s availability is calculated against eligible collateral, such as receivables, inventory or commodities, after applying advance rates and reserves.
Is a borrowing base facility the same as asset-based lending?
Not exactly. A borrowing base is the collateral formula used inside many asset-based lending facilities. ABL is the broader secured lending structure.
How often is the borrowing base updated?
It depends on the facility. Monthly reporting is common, while higher-risk or faster-moving collateral pools may require weekly or even daily reporting.
