How Much Can You Borrow With Asset-Based Lending? Commitment vs. Availability Explained

"How much can we borrow?" is usually the first question a CFO or owner asks when considering asset-based lending. The useful answer is not a single number. An ABL lender sets a commitment — the maximum facility amount — but the amount a company can draw on any given day is availability, calculated from eligible collateral, advance rates, reserves, and outstanding obligations. A $20 million commitment can have $12 million of usable availability in one month and $16 million in another.

That distinction is central to sizing an asset-based lending facility. A request based only on a growth plan or a prior bank line can miss the lender's underwriting question: how much qualified receivables and inventory support the requested facility through the normal working-capital cycle, including the low point? This borrower guide explains the difference between commitment and availability, the inputs lenders use, and how to build a lender-ready sizing request without overstating capacity.

Commitment vs. Availability: The Two Numbers Borrowers Need to Separate

Commitment is the contractual ceiling on the revolver. It is the maximum principal amount the lender has agreed to make available, subject to the credit agreement and its conditions. Commitment is important because it gives a company room for peak-season draws, letters of credit, and growth — but it is not a standing balance of cash.

Availability is the amount currently eligible to be borrowed. A simplified calculation looks like this:

Illustrative availability calculation	Amount
Eligible accounts receivable of $12.0M at 85%	$10.2M
Eligible inventory of $8.0M at 55%	$4.4M
Gross borrowing base	$14.6M
Less reserves, outstanding letters of credit, and other deductions	($1.1M)
Net borrowing base / availability before loans	$13.5M
Less current revolver loans	($8.0M)
Unused availability	$5.5M

In this illustration, a lender might offer a $15 million commitment, but the borrower cannot draw more than the $13.5 million net borrowing base before outstanding loans. If the business collects receivables, replenishes inventory, or clears a reserve, availability can rise. If aging worsens, returns increase, inventory is marked down, or a reserve is added, availability can fall. For a closer look at the calculation itself, see DCE's guide to ABL advance rates and availability.

How Lenders Size an Asset-Based Lending Facility

Lenders generally start with collateral capacity, then test whether that capacity supports the company's operating needs throughout the year. A lender is not simply choosing the highest amount the collateral could support in a favorable month. It is assessing a facility size that can work through normal volatility while preserving a prudent cushion.

1. The eligible collateral base

For a typical middle-market ABL revolver, the starting point is the accounts receivable aging and inventory detail. Lenders evaluate which receivables are eligible after exclusions for aging, disputes, concentration, foreign accounts, affiliate balances, and other factors. Inventory is reviewed by type, location, turnover, margin, and liquidation support. An advance rate applies to the collateral that remains eligible, not to the general-ledger balance.

That is why a borrower should not size a request from total AR or book inventory alone. A/R aging and cross-aging can reduce the eligible pool quickly; DCE's accounts receivable aging guide explains the lender view of those buckets. Inventory eligibility has its own filters, including obsolescence, consignment, location controls, and appraisal support.

2. The peak and trough working-capital cycle

The next question is not just "what is the borrowing base today?" It is "what does it look like in the month when cash is most constrained?" A distributor may build inventory several months before a selling season; a manufacturer may hold work in process before invoicing; a retailer may see inventory rise ahead of a holiday period while cash is tied up in open purchase orders.

Lenders typically compare monthly historical data with a forward-looking operating forecast. The objective is to understand the low point in availability, the timing of cash needs, and whether the requested commitment leaves enough capacity for normal execution. A facility that appears ample at the seasonal peak but tight at the trough can force a borrower into a rushed amendment or an overadvance discussion later.

3. Advance rates, reserves, and sublimits

Advance rates turn eligible collateral into borrowing-base capacity, but they are only one part of the structure. Reserves, ineligible collateral, letters of credit, and sublimits can materially reduce what is usable. A lender may also set a lower concentration cap for a large customer, limit inventory supported by a particular appraisal, or reserve against a known operational issue until it is resolved.

Borrowers should model the requested line using a conservative case, not only the most favorable month. The right model shows base, downside, and peak-period collateral, then identifies the assumptions that would move availability most. If a reserve is already affecting capacity, see DCE's borrower guide to requesting a reserve release for how to organize the underlying evidence.

4. Historical utilization and cash flow

Borrowing-base capacity tells a lender what collateral can support. Utilization and cash flow help explain how the company will use the line. Lenders generally want to see historical revolver usage, monthly sales and gross-margin trends, vendor payment patterns, capital expenditures, debt service, and the timing of any unusual cash needs.

A request for a materially larger facility is more credible when the borrower connects it to a specific operating driver: a higher recurring working-capital base, a documented seasonal build, an acquisition with qualifying collateral, or a new customer program with realistic payment terms. A vague request for "more flexibility" gives a credit team little to underwrite.

What Is a Practical Way to Choose the Requested Commitment?

A practical asset-based lending facility size is usually sized above expected average utilization, but not so far above the supported borrowing base that the request cannot be justified. The borrower should prepare a monthly schedule that separates three concepts:

• Borrowing-base capacity: Eligible AR and inventory multiplied by the proposed advance rates, less anticipated reserves and other deductions.
• Operating need: The expected revolver balance required to fund the cash conversion cycle, debt repayments, letters of credit, and planned working-capital needs.
• Cushion: The remaining availability needed to absorb normal collections variance, seasonal changes, and execution risk without immediately triggering restrictions or an emergency request.

For example, if a company expects peak loans of $11 million, a base-case net borrowing base of $15 million, and a seasonal low point of $12.5 million, asking for a $15 million commitment may be logical if the collateral and plan support it. Asking for $25 million because the company would like more optionality is a different question: the lender will want to know what qualified collateral and operating use support the additional $10 million.

Commitment is also not the only source of flexibility. A borrower whose forecast shows a short-lived, well-defined peak may evaluate an accordion feature, a seasonal overline, letters of credit, or a separate equipment tranche depending on the collateral and transaction. Those options have different conditions and costs; they are not interchangeable. DCE's guide to ABL accordion features explains why a pre-negotiated growth option can be more useful than trying to add capacity under pressure.

The Lender-Ready Facility Sizing Package

A lender can evaluate a facility request faster when the borrower presents the sizing logic in a concise, reconciled package. The following materials commonly help a lender understand both current collateral and future need:

1. Monthly A/R aging and inventory reports for at least the recent operating cycle, with clear identification of customer concentration, disputes, consignment, obsolete items, and unusual balances.
2. A monthly borrowing-base model that applies proposed eligibility assumptions, advance rates, reserves, letters of credit, and outstanding debt rather than relying on gross balance-sheet accounts.
3. A 12-month operating and liquidity forecast that ties sales, margin, inventory purchases, collection timing, capital expenditures, and revolver usage together.
4. A sources-and-uses explanation for any growth event, acquisition, refinancing, or seasonal build, with timing and the expected collateral effect.
5. A concise credit narrative explaining what has changed, why the facility is being requested now, what could cause the forecast to vary, and how management is monitoring the key drivers.

The package should reconcile to the financial statements and operational reporting a lender will test in diligence. When the narrative, collateral data, and forecast tell different stories, credit review slows down. For a broader checklist of lender-facing materials, review the ABL credit package guide.

Common Sizing Mistakes That Create Friction

• Treating the commitment as available cash. The borrowing base and any reserves govern the actual draw capacity.
• Using a single favorable month. A seasonal or volatile business should show the full cycle, especially the availability trough.
• Applying advance rates to gross collateral. Eligibility exclusions, concentration caps, and appraisal limits are part of the real calculation.
• Ignoring letters of credit and existing debt. Both can reduce unused availability even when collateral is unchanged.
• Requesting a larger line without a use-of-proceeds story. A lender needs to understand the operating purpose, timing, and collateral support.
• Presenting a forecast without assumptions. Credit teams will test collection periods, margins, inventory turns, and customer concentration rather than accept a top-line number.

Where DCE Fits

DCE helps borrowers translate operating data into a lender-ready ABL facility request: sizing the proposed commitment against the borrowing base, identifying the difference between headline capacity and usable availability, and organizing the assumptions a credit team is likely to test. A focused lender-placement process begins with a realistic view of collateral, cash needs, timing, and the amount of cushion the business actually requires.
