What an Advance Rate Actually Is
You get the advance rate as the percentage of an invoice a lender pays out the moment you assign it. At 85% on a £10,000 invoice, £8,500 lands in your account upfront, and the remaining £1,500 follows when your customer pays, minus fees.
Your upfront figure is the number that actually reaches your working capital. We rate it as the headline that gets over-weighted: it decides how much cash you free per invoice, but it never tells the full cost story on its own.
You feel it directly the day the money arrives.
Your reserve isn’t lost, just delayed. Picture your finance lead on the Friday an invoice is funded, seeing 85% clear now and pencilling in the rest for whenever the customer settles.
Why the Advance Rate Matters
You free more working capital per invoice at 90% than at 70%, so on the same ledger the advance rate directly sets how much of your own cash stays locked up waiting on customers.
Your headline rate can still mislead, though. We rate the common mistake as chasing the highest advance: a 90% rate carrying a high discount fee can cost you more overall than an 85% rate priced keenly, so weigh the three charges together.
You judge the rate next to the fee, never alone.
You’ll want total cost measured against cash released. Picture your accountant at month-end lining up two quotes and finding the lower advance rate leaves more in your cash flow once fees are counted.
Typical Advance Rate Ranges
You’ll usually see standard factoring and discounting land between 70 and 95%, with most facilities clustered at 80 to 90%. Where you sit in that band comes down to how a lender reads your ledger and your cash flow, not a fixed tariff.
Your debtor book does most of the talking. We rate debtor quality as the single biggest lever: creditworthy, established customers pull your rate towards the top of the range, while weak or unknown debtors pull it down.
You earn the top of the band with a clean ledger.
You’ll lift the rate with a clean payment history as much as with the names on the book. Picture your credit controller showing a lender twelve months of customers paying to terms, and watching the offered rate edge up as a result.
What Moves Your Advance Rate
You’ll find five factors move the number most: debtor quality, concentration, payment history, facility type, and sector. Each one tells the lender how confident it can be that the invoice behind your advance will actually get paid.
Your concentration is the quiet one to watch. We rate it as the trap: once a single customer passes 25 to 40% of the ledger, the lender’s exposure spikes, and it often caps the advance or lowers the rate, squeezing your cash flow.
You can be strong overall and still capped on one big account.
You’ll also see facility type and sector shift it: factoring can edge above discounting, and construction sits lower for set-off and retention risk. Picture your finance director on a Monday learning one dominant client has quietly pulled the whole facility’s rate down.
The Retained Percentage
You don’t lose the portion the lender holds back, the reserve; it’s a buffer. It absorbs the discount fees that accrue while the invoice is outstanding, the service charge on turnover, any disputed amounts, and bad-debt losses on a recourse facility.
Your reserve comes back net of fees when the customer pays in full and on time. We rate it as the part worth understanding early, because a disputed invoice or a credit note is settled straight out of it before anything reaches you.
You only see the reserve once the invoice truly clears.
A short payment leaves you the difference, not the lender. Picture your accountant reconciling a customer who paid £9,000 on a £10,000 invoice, and watching the reserve absorb the £1,000 shortfall against your cash flow.
Advance Rate FAQs
What is a typical invoice finance advance rate?
For standard invoice factoring and discounting, advance rates usually fall between 70 and 95%, with most facilities sitting at 80 to 90% of invoice value. Where you land within that range depends mainly on the creditworthiness of your customers, the concentration of your debtor book, your payment history and your sector. The remainder is held back as a reserve and released, minus fees, once your customer pays.
Why is my advance rate lower than 90%?
Several things can pull an advance rate down: weak or unknown debtors, a ledger where one customer represents more than around 25 to 40% of the book, a history of slow or disputed payment, or a higher-risk sector such as construction where set-off and retention are common. Lenders set the rate on how confident they are the underlying invoice will be paid, so a concentrated or higher-risk ledger typically attracts a lower advance rate.
Is a higher advance rate always better?
Not necessarily. The advance rate is only one of three numbers that determine the real economics of a facility, alongside the discount charge (interest on the funds drawn) and the service charge. A 90% advance rate carrying a high discount fee can cost more overall than an 85% rate priced more keenly. Always compare the total cost of borrowing against the cash actually released, rather than picking the highest headline advance rate.
What is the retained percentage or reserve?
The retained percentage is the part of each invoice the lender doesn’t advance upfront, typically 10 to 30%. It acts as a buffer that absorbs the discount and service fees, any disputed amounts or credit notes, and bad-debt losses on a recourse facility (where the advance is charged back if the customer doesn’t pay). When the customer pays in full and within terms, the reserve is released to you net of fees; if they pay short, the reserve absorbs the shortfall.
How we reviewed advance rates
What we covered. We explain what an invoice finance advance rate is in 2026, the typical 70-95% range, what moves it up or down, and how the retained reserve works. We don’t rely on comparison-site summaries or aggregator data.
Data sources. Advance-rate ranges were checked against primary sources in July 2026, including provider pricing pages and the facilities we assess in our invoice finance reviews, alongside the Bank of England base rate of 3.75%.
How we handle gaps. Where the rate varies by provider, we give the market range rather than a single false-precision number, and we flag that your own rate depends on debtor quality, concentration and sector.
Update cadence. We re-verify this page at least monthly, and whenever market pricing moves. The verification date reflects the most recent full review. Some links on this page are affiliate links, see our editorial policy.
