Working Capital Finance: Options and Costs
How working capital financing works in the US, real 2026 pricing across revolvers, factoring, ABL and term loans, and how to pick the right one.
Fund the cycle, not the gap.
Working capital financing closes the gap between paying your suppliers and payroll and collecting from your customers. That gap has a name, the cash conversion cycle, and it explains why a profitable, growing business can still run out of cash. In the Federal Reserve's 2024 Small Business Credit Survey, 59% of employer firms sought financing in the prior year, and 56% of financing seekers cited operating expenses as the reason. Only 41% of applicants got all the financing they asked for. This page walks through why the gap opens, the instruments that close it, what each one actually costs in 2026, and how to match the tool to the cause instead of taking whatever a broker calls you about first.
01
The gap, explained
Every business that sells on credit or holds inventory has a cash conversion cycle: days of inventory outstanding, plus days sales outstanding, minus days payable outstanding. A distributor that holds stock for 60 days, collects in 45, and pays suppliers in 30 has a 75-day cycle. Every dollar of growth during that period needs financing, because the cash from this month's sales is still sitting in a customer's accounts payable ledger when next month's payroll and supplier invoices come due.
Two different problems get lumped together under "working capital" and they need different fixes. A permanent gap comes from steady growth, a longer customer payment cycle than your industry average, or a structurally thin margin; it needs a revolving facility sized to the ongoing cycle, not a one-time loan. A seasonal gap comes from building inventory ahead of a predictable peak, retail before the holidays or agriculture ahead of harvest; it needs a facility that draws up and clears down on a known calendar, not permanent debt. A one-time gap, a large confirmed order or an acquisition, needs a transaction-specific tool sized to that single event. Financing a permanent gap with a six-month, daily-repayment product, or financing a one-time spike with a permanent revolver, is how otherwise healthy businesses end up refinancing in a panic.

The option set
| Instrument | Best for | Typical size | Speed to fund |
|---|---|---|---|
| Bank line of credit (LOC) | Recurring, self-liquidating gap; established borrower | $10,000-$3 million | 2-6 weeks |
| SBA 7(a) Working Capital Pilot | Same, for borrowers who don't fit conventional bank credit alone | Up to $5 million | 5-10 weeks |
| Asset-based lending (ABL) | Larger, AR/inventory-backed revolver; scale or lower credit quality | $1 million-$25 million+ | 4-8 weeks (bank ABL can run longer) |
| Invoice factoring / AR finance | B2B invoices, long customer terms, weaker balance sheet | $30,000-$5 million | 3-10 business days after setup |
| Purchase-order finance | A single confirmed order that exceeds current capacity | $100,000-$25 million | 3-10 business days, longer for imports |
| Online fintech LOC | Fast, small, short-term draws | $2,000-$250,000 | 1-3 business days |
| Merchant cash advance / sales-based financing | Last resort or very short cycle; avoid for chronic losses | $5,000-$1 million | Often same-day |
Cost comparison
Every one of these is priced differently, which is exactly why owners compare the wrong numbers. A factor rate or discount fee is not an annual interest rate, and the only fair comparison is cash received versus total dollar cost versus repayment period.
| Product | Current price and fees | Advance / structure |
|---|---|---|
| Bank unsecured LOC ($10,000-$150,000) | Prime + 1.75% to +9.75% (about 8.5%-16.5% at the current 6.75% prime), plus a $95-$175 annual fee | Revolving, annual renewal, personal guarantee common |
| Bank borrowing-base LOC ($100,000-$3 million) | Roughly Prime + 0.5% to +4.0%, plus about 0.25% annual line fee | Interest-only on draws, 1-3 year commitment, AR/inventory formula |
| SBA Working Capital Pilot (up to $5 million) | Statutory caps: 13.25% under $50,000; 12.75% up to $250,000; 11.25% up to $350,000; 9.75% above that, at 6.75% prime, plus a 0.25%-0.275% guarantee fee | Monitored AR/inventory or transaction-based line, up to 60 months, unlimited personal guarantee from 20%+ owners |
| Bank ABL ($5 million+) | Roughly SOFR + 2.0% to +4.0% (about 5.6%-7.6% at current SOFR), unused fee 0.20%-0.50%, origination 0.25%-1.0% | Up to 85% of eligible AR, roughly 50%-65% of eligible inventory cost, 3-5 year term |
| Non-bank ABL ($1 million-$25 million) | Roughly SOFR + 4.0% to +7.0%, stretch structures to +8.0% | AR advance 80%-90%, inventory 40%-65% of cost, 2-4 year term |
| Invoice factoring ($30,000-$5 million) | Initial fee 0.5%-3.0% for the first 30 days, plus 0.25%-1.5% per further 10-30 days | Advance 80%-95%, released on customer payment less fees |
| Online fintech LOC ($2,000-$250,000) | From about 7.8% for the strongest borrowers up to total draw fees of 3%-27% depending on term (Amex), or an average 56.6% APR on originations (OnDeck) | Weekly to monthly repayment over 6-24 months |
| Merchant cash advance ($5,000-$1 million) | Factor rate typically 1.2 to 1.5 ($1.20-$1.50 repaid per $1 funded); the FTC notes effective APRs can reach triple digits | Daily or weekly holdback of 5%-20% of revenue, 3-18 month expected term |
A factor-rate example makes the trap concrete. $100,000 funded at a 1.35 factor rate means $135,000 owed back. Repaid daily over six months, the simple annualized finance charge is roughly 70% before fees, well above what the "1.35 factor rate" sounds like on its own. On the factoring side, a 3% fee on a $100,000 invoice with an 85% day-one advance is a $3,000 cost to access $85,000 of cash, not $100,000, so if it's collected in 30 days the simple annualized cost on the cash actually advanced is closer to 42%, not 3% a month flat.

Matching the instrument to the cause
- Steady growth outrunning cash, invoicing terms of net-45 or longer to creditworthy customers: an AR line, ABL, or factoring facility that scales with sales, sized to the actual cash conversion cycle rather than a fixed loan amount.
- Seasonal inventory build, a known peak (holiday retail, harvest, back-to-school): a revolver that draws ahead of the peak and clears down after collection, not a fixed-term loan that keeps amortizing through the slow season. Size the peak draw from a 13-week cash forecast, not last year's guess.
- A single confirmed order beyond current capacity: purchase-order financing, funding 70%-100% of supplier cost against that specific order, repaid from the customer remittance, often handed off to a factor after shipment.
- Thin, established, bankable credit: a bank LOC or SBA Working Capital Pilot line, the cheapest cost of capital available if you qualify.
- Weak balance sheet but strong customers: invoice factoring, which prices off the customer's credit and payment history more than yours.
- A funding gap you cannot trace to a specific cause, alongside chronic losses: none of these products fix that. A fixed daily-debit MCA on top of an unprofitable operation compounds the shortfall instead of bridging it.
04
Term sheet anatomy: what to actually compare
Every offer should be reduced to the same handful of numbers before you sign anything:
- Net cash received after origination and any broker fee, not the face amount of the facility.
- Total dollar finance charge over the expected repayment period, and again under a stressed 90-day-late scenario.
- Effective APR from the actual, timed cash flows, not the headline factor rate or discount percentage.
- Unused-line fee at your expected utilization. A cheap $5 million ABL with a 0.5% unused fee is expensive if you only draw $500,000.
- Advance rate against eligible collateral, not gross AR or inventory. A $1 million gross AR ledger, after removing aged, disputed, and concentrated balances, might leave only $750,000 eligible, and an 85% advance on that is $637,500, not $850,000.
- Repayment frequency and term, matched to how long the underlying inventory or receivable actually takes to convert to cash.
- Collateral, lien position, and guarantee: a blanket first-lien UCC-1 filing on one facility can block a second lender from closing, and owners at 20% or more equity give an unlimited personal guarantee on any SBA facility.
- Prepayment and minimum-interest terms: ordinary interest usually falls with early payoff; fixed-fee MCA and some minimum-interest ABL structures do not.
05
Qualification
Bank lines want two or more profitable years, stable deposits, and reasonable leverage; the cheapest posted pricing goes to borrowers with a full banking relationship and clean debt-service coverage. SBA's Working Capital Pilot requires 12 full months of operating history and the ability to produce timely AR/AP agings and inventory reports, since the facility is actively monitored. ABL and factoring qualify off the receivable or collateral itself as much as the borrower: a startup with weak personal credit but strong, creditworthy customers and clean invoices can often get factored or PO-financed when it couldn't get a bank line. Online fintech products trade documentation for speed and price, underwriting mostly off bank deposits and time in business.
06
Pitfalls
Comparing a factor rate straight to an APR is the single most common mistake. Borrowing for a period shorter than your actual cash conversion cycle is the second, a six-month daily-repayment product cannot safely carry inventory that takes nine months to turn into cash. Sizing a request off gross AR or inventory instead of the eligible base after concentration, aging, and dilution reserves routinely overstates real availability by 20% to 50%. Stacking a merchant cash advance on top of an existing blanket lien, or stacking multiple MCAs against each other, can both wreck liquidity and prevent a bank or factor from ever closing a cleaner facility later. And submitting financials that don't reconcile across tax returns, bank deposits, and AR agings is the fastest way to kill an application outright, regardless of the underlying business quality.
07
A note for UK borrowers
The mechanics are the same on both sides of the Atlantic, revolving facility against receivables or inventory, sized to the cash conversion cycle, priced off Bank Rate rather than SOFR or prime. UK invoice finance runs through a different set of named providers and a Companies House charge-registration step in place of a UCC-1 filing. See our dedicated page on invoice finance for UK-specific pricing and providers.

FAQ
Finance the maximum forecast cash deficit through one full operating cycle plus a defined contingency, not simply current assets minus current liabilities. Build a 13-week cash forecast and a monthly seasonal case, and hold back the minimum cash the business needs to keep running.
A revolver fits a recurring, self-liquidating gap because interest applies only to what's drawn and the line refills as invoices are collected. A term loan fits a one-time need with a known payback. Using repeated short-term loans to cover a permanent seasonal need just creates repeated fees and refinancing risk.
For a strong, established small business, posted bank line pricing runs from about 8.5% to 16.5% at the current prime rate. SBA Working Capital Pilot caps range from 9.75% to 13.25% depending on facility size. ABL, factoring, online lines, and merchant cash advances all price on a different basis; compare effective APR and total dollar cost, not the headline percentage.
Conventional banks generally want two or more years in business, and SBA's Working Capital Pilot requires 12 full months. A startup can often still get factoring or purchase-order financing if the underlying customer, invoice, and supplier are strong, though the cost and reporting requirements are higher.
Yes. A blanket first-position lien can stop a later lender or factor from taking the priority they need to close. Before paying off an existing facility, get a payoff letter with a clear deadline for filing the UCC-3 termination, and before refinancing, confirm whether assignment or subordination is possible.
