What it means
Advance rates appear wherever lending is secured on specific assets: invoice finance, inventory lines, equipment loans and asset-based lending facilities generally. The lender is answering one question, which is how much of this collateral could it realistically recover if the borrower failed and the assets had to be collected or sold in a hurry.
That explains why rates differ so sharply by asset type. Trade receivables owed by creditworthy customers might attract 80% to 90%, finished goods inventory perhaps 50%, and raw materials or work in progress considerably less or nothing at all.
The more predictable and easily converted the asset, the higher the advance rate. The rate only applies to eligible collateral, and eligibility rules do more damage to availability than the percentage itself.
Lenders routinely exclude invoices more than ninety days old, balances owed by related parties, disputed amounts and concentration above a set share from any single customer, so gross receivables and eligible receivables can be very different numbers. Multiplying eligible collateral by the advance rate produces the borrowing base, which caps how much can be drawn regardless of the facility limit.
The borrowing base is usually recalculated monthly or even weekly, so availability moves with trading, which is precisely why asset-based facilities are described as flexing with the business. The risk sits in that flexing.
Availability falls fastest when receivables age, a large customer becomes concentrated or inventory turns slowly, and those things tend to happen exactly when a business most needs cash. Treating the headline facility limit as guaranteed funding, rather than the borrowing base as the real constraint, is the mistake that catches most first-time borrowers.
In practice
Real-world examples.
Example
A recruitment agency funds contractor payroll through invoice finance at an 85% advance rate. It invoices $500,000 in a month, draws $425,000 immediately to pay contractors, and receives the remaining balance less fees when the client settles.
Example
A seasonal toy distributor negotiates a temporary uplift in its inventory advance rate from 50% to 60% for the three months before peak season. The extra availability funds the stock build, and the rate steps back down once the goods have been sold and converted into receivables.
Example
A manufacturer discovers its borrowing base has fallen by $300,000 even though sales grew, because one customer now represents more than the permitted 25% concentration limit and the excess has been made ineligible. The finance director accelerates collections from that customer and broadens the customer base to restore availability.
Formula
Calculation
Borrowing base = eligible collateral value x advance rate. Available headroom = borrowing base - amount currently drawn.
A wholesale distributor has an asset-based facility with a $2,500,000 limit. Its lender applies an 85% advance rate to eligible receivables and a 50% advance rate to eligible finished goods inventory.
At month end the distributor has $2,000,000 of eligible receivables and $800,000 of eligible inventory.
Receivables availability = $2,000,000 x 85% = $1,700,000.
Inventory availability = $800,000 x 50% = $400,000.
Borrowing base = $1,700,000 + $400,000 = $2,100,000.
The facility limit is $2,500,000, but the borrowing base of $2,100,000 is lower, so $2,100,000 is the true ceiling. With $1,500,000 already drawn, available headroom is $2,100,000 - $1,500,000 = $600,000.Case study
Seen in the real world.
Calderworth Supplies is a fictional industrial distributor used here as an illustrative example. It signed a $2,500,000 asset-based facility and built its cash forecast on that limit, assuming the full amount would be available whenever it was needed.
In its busiest quarter Calderworth won a large contract with a single national retailer that grew to 40% of its receivables. The lender applied a 25% concentration cap, made the excess ineligible, and the borrowing base fell to $2,100,000 just as the company was funding extra stock. With $1,500,000 drawn, the fictional finance director found only $600,000 of headroom against a plan that had assumed $1,000,000.
Calderworth recovered by agreeing a temporary carve-out for that retailer at a lower advance rate, tightening collections on invoices approaching ninety days, and rebuilding its forecast around the borrowing base rather than the facility limit. The illustrative point is that in asset-based lending, eligibility rules and advance rates, not the headline number, decide what you can actually draw.
Watch out
Common mistakes.
- Treating the facility limit as available cash. The borrowing base, not the limit, sets what can be drawn, and it moves every time collateral is recalculated.
- Ignoring eligibility criteria. Ageing invoices, disputed balances, related-party debts and customer concentration can strip out a large slice of collateral before the advance rate is even applied.
- Assuming the advance rate is fixed forever. Lenders can reduce it after a review, a bad debt run or a change in trading, and most facility agreements give them that right.
Questions
People also ask.
What decides the advance rate a lender offers?
Collateral quality, the spread and creditworthiness of customers, historical dilution from credit notes and returns, and how easily the asset could be sold or collected.
Is a higher advance rate always better?
Not necessarily; it usually comes with higher pricing, tighter reporting and more covenants, so the cheapest facility is often not the one advancing the most.
How often is the borrowing base recalculated?
Commonly monthly, though weekly or even daily reporting is used for higher-risk facilities, and late reporting can itself suspend availability.
