Best Working Capital Loan Rates in May 2026: 6%–35% APR Compared

Working capital loan rates in 2026 run from 6% APR on the cheapest bank-grade term debt to 35%+ APR-equivalent on the fastest revenue-based advances. The range is wide because "working capital loan" describes six structurally different products, each with its own rate basis, qualification thresholds, and funding speed. The product you actually qualify for matters more than chasing the lowest headline rate — the cheapest rate you don't qualify for is irrelevant.

Product	2026 rate range	Rate basis	Best profile	Funding speed
Bank working capital loan	6–12% APR	Fixed APR, 1–5 yr term	2+ yrs, FICO 700+, $500K+ revenue, collateral	30–90 days
SBA 7(a) working capital	10.5–13% APR	Prime + 2.25–4.75% (variable)	2+ yrs, FICO 680+, $150K+ revenue	45–75 days
SBA Express working capital	11.25–13.25% APR	Prime + 4.5–6.5%	2+ yrs, FICO 680+, smaller deals	30–45 days
Business line of credit (bank)	8–14% APR	Variable, often Prime + spread	2+ yrs, FICO 720+, banking relationship	15–45 days
Business line of credit (online)	12–22% APR	Variable APR	1+ yr, FICO 650+, $100K+ revenue	1–7 days
Online working capital loan	12–35% APR	Fixed APR, 6 mo–3 yr term	1+ yr, FICO 625+, consistent revenue	1–3 days
Invoice financing	1–4% per invoice	Fee per invoice, not APR	Strong B2B receivables	3–7 days first deal
Revenue-based advance	Factor pricing*	Fixed total payback, not APR	$15K+/mo revenue, 6+ mo in business	4–24 hours

*Revenue-based advances are not loans — they are sales of future receivables priced as a factor (total payback ÷ funded amount) rather than as APR. Effective cost varies meaningfully by payback speed, so direct rate-to-rate comparison with APR-based products isn't apples-to-apples.

The Prime rate sits at 6.75% in May 2026 (Fed held steady through Q1, cut once in April), which sets the floor for everything tied to it — SBA, bank lines of credit, and bank working capital loans.

Bank rates start near Prime (currently 6.75% in May 2026) plus a small spread. Established businesses with multi-year operating history and 700+ FICO secure 6–9% APR for working capital purposes. Newer or smaller businesses get pushed higher — 9–12% — though many won't qualify for a bank working capital loan at all without 2+ years of operation, $500K+ annual revenue, and real collateral.

The rate trade-off is the slowest funding timeline (30–90 days) and the strictest qualification. Banks reject roughly 80% of small business applications under $250K — when they approve, you get the cheapest rate available, but the approval rate is the gate.

What pushes a bank working capital loan rate higher or lower

• Personal FICO under 720 — typically adds 1–2 points to the rate
• Less than $500K annual revenue — adds 1–2 points or triggers decline at most banks
• No banking relationship with the lender — banks price relationship customers 0.5–1 point better
• Asking for unsecured working capital — banks price secured (collateralized) 1–3 points cheaper than unsecured
• Industry risk — restaurants, trucking, construction, retail all price 1–3 points higher than professional services, healthcare, or established B2B

SBA 7(a) working capital loans are capped by the SBA at Prime + 4.75% on loans under $50K, sliding to Prime + 2.25% on loans over $250K. With Prime at 6.75% in May 2026, that translates to an effective 9–11.5% APR across the size range — lower than the 2025 range because Prime came down 25 basis points in April 2026.

SBA Express working capital sits higher (Prime + 4.5–6.5%, so 11.25–13.25% APR) with faster funding (30–45 days vs 45–75 for standard 7(a)) and lower SBA guarantee (50% vs 75–85% on standard 7(a)).

SBA working capital eligibility (2026)

• 2+ years in business — SBA 7(a) and Express both
• FICO 680+ — practical floor; flex lenders work down to 650
• $150K+ annual revenue — for 7(a); SBA Express works lower at ~$50K+
• SBA-eligible structure — for-profit, 51%+ US-citizen ownership, no federal debt delinquency, owner residency

Online lenders bridge the gap between bank-grade and alternative-funder pricing. Typical 2026 ranges sit at 12–35% APR depending on credit, revenue consistency, and time in business. The premium over bank rates pays for speed (1–3 day funding vs 30–90 days), more flexible underwriting, and bank-statement-based qualification rather than full document review.

Specific online working capital loan rate tiers in 2026:

• Top-tier online (FICO 700+, 2+ yrs, $250K+ revenue): 12–18% APR
• Mid-tier online (FICO 650+, 1+ yr, $100K+ revenue): 18–28% APR
• Subprime online (FICO 600+, 6+ mo, $50K+ revenue): 28–35% APR

Online lender working capital loans typically run 6–36 months and repay weekly or monthly. The shorter terms keep the total interest paid manageable even at higher APRs — a 12-month loan at 25% APR pays roughly the same total interest as a 5-year loan at 12% APR.

Business lines of credit run 8–22% APR in 2026. The wide range reflects two distinct lender categories:

• Bank lines of credit: 8–14% APR for businesses with FICO 700+, 2+ yrs, and a banking relationship. Bank-grade lines often require collateral and may require periodic paydown to zero. Approval 15–45 days.
• Online lines of credit: 12–22% APR for businesses with FICO 650+, 1+ yr, and $100K+ annual revenue. Unsecured, draw-on-demand, approval in 1–7 days.

You only pay interest on what you actually draw, which makes line-of-credit rates more forgiving than the headline APR suggests. A $100K line at 14% APR used at 30% average utilization costs roughly $4,200/year in interest, not $14,000. That makes lines materially cheaper than equivalent-rate term loans for intermittent or seasonal use.

Revenue-based working capital advances aren't loans, and they don't express cost as an APR. Cost is a factor (total payback ÷ funded amount) on the funded amount, repaid through small fixed daily or weekly ACH debits tied to your business deposits. Bay Street Lending does not display factor rates publicly because every business has a different cost profile — published numbers would mislead more borrowers than they help.

What you can know directionally about revenue-based working capital cost in 2026:

• Cost scales inversely with payback term. A 9-month payback costs less than a 3-month payback on the same advance — the funder takes on less risk over a shorter window.
• Effective cost is 3–10× the rate of a bank or SBA loan when expressed in comparable terms. The premium pays for compressed underwriting and same-day funding.
• Profile drives 30–50% of pricing within the product. A 700 FICO with 2 years operating history and $80K/month consistent revenue prices materially better than a 550 FICO with 8 months and volatile deposits.
• Repeat funding prices better than first-time funding. Once you complete one cycle with a funder and pay back on schedule, subsequent advances typically price 15–30% below the first-time number.

Invoice financing is priced as a fee per invoice rather than as APR. Typical 2026 rates:

• Recourse factoring: 1.0–2.5% for invoices paid in 1–30 days; 2.0–3.5% for 31–60 days; 3.0–4.5% for 61–90 days
• Non-recourse factoring: 0.5–1.5% premium over recourse rates (factor absorbs customer insolvency risk)
• Spot factoring (single invoice): 3–5% per invoice — meaningfully more than whole-ledger because the factor isn't getting volume benefit

The APR equivalent for a 30-day invoice factored at 2.5% is roughly 30% APR. That seems high vs bank loans, but invoice factoring is the only product that qualifies on your customer's credit rather than yours — accessible to businesses with weak credit, short operating history, or volatile revenue who can't clear bank or SBA thresholds. For the full factoring cost breakdown, see our invoice factoring guide.

Five variables push your individual rate within the product range. Improving any one of them before applying typically saves 1–4 percentage points on the final offer:

1. Personal FICO score. Each 30-point band moves rate 1–2 percentage points within the same product. 720+ unlocks bank pricing; 680+ unlocks SBA; 650+ unlocks competitive online; below 600 limits options to revenue-based products.
2. Time in business. 2+ years unlocks bank and SBA pricing tiers. 1–2 years sits in online lender territory. 6–12 months limits options to revenue-based or invoice financing.
3. Monthly revenue consistency. Lenders price stability — $50K/month every month consistently outprices a single $200K month surrounded by $20K months. Consistency matters more than absolute volume in 2026 underwriting.
4. Industry risk grade. Restaurants, trucking, construction, retail, and seasonal businesses all price 2–4 points higher than professional services, healthcare, B2B SaaS, or established manufacturing on the same product.
5. Collateral and personal guarantee. Real collateral drops bank rates 1–3 points vs unsecured. Most online and revenue-based products are unsecured and price accordingly.

The single highest-leverage way to lower your working capital loan rate isn't shopping more lenders — it's improving the input variables (FICO, revenue consistency, time in business) before applying. A 700 FICO with 2 years easily clears 4–6 points of effective rate vs the same business at 620 FICO with 1 year.

The quoted interest rate isn't the full cost. Five fees commonly layer on top:

• Origination fee: 1–6% of loan amount, typically deducted from disbursement. Bank loans usually 0.5–2%; online lenders 2–6%.
• SBA guaranty fee: 0.55–3.75% of the guaranteed portion, rolled into the loan amount. Capped by SBA size rules.
• Underwriting / packaging fee: $1,500–$5,000 on bank and SBA deals; typically waived on online and revenue-based products.
• Monthly maintenance fee: $50–$500/month on some line-of-credit products regardless of draw status.
• Prepayment penalty: Most bank working capital loans have no prepayment penalty; SBA 7(a) over 15 years has a declining penalty in the first 3 years; revenue-based advances typically do not allow early payoff for discount.

The honest comparison: model the full repayment schedule, including all fees, against your projected revenue. A 9% APR bank loan with 2% origination and $250/mo line-maintenance is effectively 11–14% APR on small loans; a revenue-based advance with a 1.25 factor paid back in 6 months may be cheaper than it looks at the headline factor.

Working capital loan rates in May 2026 sit roughly 50–150 basis points below 2025 highs across most products. The drivers: Prime cut once in April 2026 (8% → 6.75%), and online-lender competition has driven the alternative-funder spread down slightly.

Product	Mid-2025 typical	May 2026 typical	Δ
Bank working capital loan	8–13% APR	6–12% APR	~150 bps lower
SBA 7(a) working capital	11.5–14% APR	9–11.5% APR	~250 bps lower (Prime cut)
Business line of credit (bank)	9–15% APR	8–14% APR	~100 bps lower
Online working capital loan	14–38% APR	12–35% APR	~200 bps lower
Revenue-based advance	factor 1.20–1.50	factor 1.15–1.45	marginal — competitive pressure

The structural shift in 2026: bank-statement aggregation via Plaid has gone from optional to default, which has compressed underwriting time on online and revenue-based products. Speed is up, not just cost down.
