Working Capital Loans: How They Work, Rates and Where to Get One

A working capital loan gives your business a revolving credit line to cover day-to-day expenses (payroll, inventory, rent) instead of handing you a single lump sum. You draw what you need, pay interest only on the amount you use, and replenish your credit as you repay. With the SBA Working Capital Pilot Program now offering rates as low as 9.75% and loan amounts up to $5 million, this is the most accessible government-backed revolving credit program for small businesses in 2026.

Your cost depends entirely on your credit profile and which lender tier you qualify for. An established business with 680+ credit can lock in SBA rates between 9.75% and 13.5%. A startup with 600 credit might pay Fundbox weekly fees starting at 4.66% on a 12-week draw. A business with a 500 score could end up paying factor rates that translate to 40%+ effective APR through lenders like Taycor Financial.

This guide covers the exact rates, credit minimums, and application steps for every tier. If you need a broader overview first, check out our guide on how to get a business loan or compare the best small business loans available right now.

A working capital loan is a revolving line of credit (not a term loan) that funds your business's short-term operational needs. You draw against a pre-approved credit limit, use the funds for expenses like inventory, payroll, or supplier invoices, then repay and draw again. It works like a business credit card but at significantly lower interest rates for qualified borrowers.

The SBA's 7(a) Working Capital Pilot Program (WCP) is the first SBA program to combine domestic and international transaction financing in a single credit line. It operates under the 7(a) loan umbrella with terms up to 60 months and an 85% SBA guaranty for loans up to $150,000 (or 75% for larger loans).

You should consider a working capital loan when your business has predictable revenue but unpredictable timing. Seasonal retailers, B2B companies with 30-to-90-day payment terms, and manufacturers fulfilling large contracts are the primary use cases. If you need a one-time lump sum for equipment or real estate, a standard SBA loan or term loan is a better fit.

Eligibility varies dramatically by lender. The table below shows what each lender tier requires.

• SBA WCP: Personal credit score of 680+, at least 12 months in business, ability to produce accurate financial statements and receivable/payable reports, and your business must meet SBA size standards for your industry.
• Fundbox: Personal credit score of 600+, just 3 months in business, and $30,000 in annual revenue (per LendingTree, as of 2026). Maximum credit line of $150,000.
• OnDeck: Personal credit score of 625+, at least 12 months in business, and $100,000 in annual gross revenue. Lines of credit from $6,000 to $200,000.
• Taycor Financial: Personal credit score as low as 500 for some products (and 560+ for working capital lines), 3 months minimum in business. Factor rates starting at 1.01.

For SBA WCP specifically, your advance rates are capped by asset type. Domestic receivables qualify for up to 85% advance, insured foreign receivables up to 90%, uninsured foreign receivables up to 70%, and U.S. inventory up to 60%. If you are a brand-new business with no receivables, explore business loans for startups or microloans first.

The application process differs based on whether you pursue an SBA-backed line or an online lender. Here is the general flow for both paths.

SBA WCP Path (2 to 6 weeks): Find a PLP-WCP lender through the SBA Lender Match tool. PLP lenders have delegated authority to approve your loan without SBA headquarters review, saving significant time. Prepare 2-3 years of tax returns, current financial statements, AR/AP aging reports, and any contracts or purchase orders. Loans over $2 million trigger a mandatory on-site field review. The SBA will review your application through the Loan Guaranty Processing Center if your lender does not have PLP authority.

Online Lender Path (1 to 3 days): Fundbox and OnDeck let you apply online in under 10 minutes. Fundbox links to your bank account or accounting software, uses AI to assess your financials, and can fund as soon as the next business day. OnDeck requires 3 months of bank statements and can fund within 24 hours for term loans up to $200,000 (same-day funding is available in many states for qualifying applicants). Both perform a soft credit check initially, so your score is not affected until you draw funds.

Regardless of which path you choose, get quotes from at least 3 lenders and compare the total cost of capital, not just the headline rate. A lower origination fee on one offer can offset a slightly higher interest rate on another.

The SBA WCP caps rates based on loan size, all tied to the prime rate (6.75% as of January 2026, per the Federal Reserve FRED data). Here is the breakdown:

• Loans up to $50,000: Maximum 13.5% (Prime + 6.5%)
• Loans $50,001 to $250,000: Maximum 12.75% (Prime + 6.0%)
• Loans $250,001 to $350,000: Maximum 11.25% (Prime + 4.5%)
• Loans over $350,000: Maximum 9.75% (Prime + 3.0%)

SBA guarantee fees add 0.25% to 3.75% of the guaranteed portion, though small manufacturers (NAICS 31-33) pay 0% on 7(a) loans up to $950,000 through September 30, 2026. Online lenders cost significantly more. OnDeck's average APR for business lines of credit is approximately 57.10% (per Bankrate, as of 2026). Fundbox charges weekly fees starting at 4.66% for 12-week terms and 8.99% for 24-week terms, which appear low but are not annualized APR figures.

Factor-rate lenders like Taycor Financial charge rates from 1.01 to 1.40. A 1.36 factor rate on a $10,000 12-month loan means you repay $13,600 total, equivalent to roughly 70% APR. Always convert factor rates to APR before comparing offers. For a deeper look at factor-rate math, read our merchant cash advance guide.

Compare it against our full list of business line of credit options.

If your credit score is below 600 or you have been in business for less than 3 months, traditional working capital loans may not be an option yet. Here are your alternatives, ranked from lowest to highest cost:

• SBA Microloans: Up to $50,000 through nonprofit intermediaries. Rates of 8% to 13%. Available to startups and businesses that cannot get conventional financing.
• Business Credit Cards: Many offer 0% intro APR for 12-15 months. Good for bridging short-term gaps under $25,000. Build your business credit at the same time.
• Invoice Factoring: Sell your unpaid invoices for 80% to 90% of face value and receive cash in 1-3 days. Costs 1% to 5% of the invoice per month. No credit score minimum.
• Small Business Grants: Free money that does not require repayment. Highly competitive, but worth applying if you are a minority-owned, women-owned, or veteran-owned business.
• Merchant Cash Advance: Fastest approval (same day), but effective APR ranges from 40% to 150%+. Use only as a last resort for emergency cash.

If you are a very early-stage company still raising capital, our pre-seed funding and angel investors guide cover equity-based alternatives that do not require repayment at all.

1. Borrowing more than your working capital supports. Most lenders cap your line at your current working capital amount (assets minus liabilities). A $50,000 working capital balance means your maximum line is typically $50,000, regardless of what a lender advertises. Borrowing beyond this increases your default risk and may trigger personal guaranty collection.

2. Ignoring advance rate caps on receivables. Even with an 85% advance rate on domestic receivables, you cannot access funds until qualifying invoices exist. Inventory advances cap at 60%. If you project $500,000 in receivables but only have $200,000 on the books today, your available draw is roughly $170,000 (85% of $200K), not $425,000.

3. Confusing factor rates with interest rates. A factor rate of 1.01 on a $50,000 advance costs $500 in fees. That looks cheap until you realize it is a 12-week product and the annualized cost exceeds 25% APR. Taycor's factor rates can go as high as 1.40, which on a $10,000 12-month loan equals $13,600 total repayment (roughly 70% APR).

4. Stacking hidden fees on top of interest. Some lenders charge origination fees (up to 5%), monthly maintenance fees ($20/month at OnDeck), and per-draw fees. On a $100,000 line with a 3% origination fee, you lose $3,000 before you even use the money. Read the full fee schedule and add every fee to your total cost calculation.

5. Failing to shop multiple lenders. The difference between SBA WCP rates (9.75%) and an online lender's average APR (57%+) is enormous. Even if you only have fair credit, getting quotes from 3+ lenders can save thousands. Use the SBA's Lender Match tool and at least one online marketplace like Nav.com.
