Every Way to Fund a Small Business, Compared

The short answer

There is no single best way to fund a small business. The right capital depends on three things: how fast you need it, how strong your credit and revenue history are, and what you're using it for.

Bank lines of credit and SBA loans cost the least but take weeks and require strong credit. Merchant cash advances and other revenue-based advances cost the most but fund in 24-48 hours and accept FICO 500+. Equipment financing and invoice factoring fit specific situations (an asset purchase or B2B receivables, respectively). Credit cards are cheaper than an advance below ~$15K but expensive above that.

This guide walks through every common option with honest cost, speed, and qualification numbers. Read it once, then pick the option that fits your actual situation, not the one a salesperson is pushing.

Comparison at a glance

Here's every common funding type side-by-side. Numbers are typical ranges in mid-2026, your specific quote depends on your credit, revenue, time in business, and industry.

• Bank term loan, Cost: 7-15% APR. Speed: 2-8 weeks. Qualification: 680+ FICO, 2+ years in business, collateral or strong financials. Best for: large stable purchases, predictable cash flow.
• SBA 7(a) loan, Cost: prime + 2.25-4.75% (≈10-14% APR mid-2026). Speed: 30-90 days. Qualification: 680+ FICO, 2+ years, SBA underwriting (very thorough). Best for: lowest possible cost when you have time and clean financials.
• Business line of credit, Cost: 8-25% APR on drawn balance. Speed: 1-4 weeks (bank), 1-3 days (online). Qualification: 650+ FICO, established revenue. Best for: ongoing variable needs, payroll bridges, inventory.
• Merchant cash advance (MCA), Cost: factor rate 1.15-1.50× (no APR; see our factor-rate explainer). Speed: 24-48 hours. Qualification: 500+ FICO, 6+ months in business, $20K+ monthly revenue. Best for: time-critical needs, variable-revenue businesses, sub-650 credit.
• Revenue-based financing (RBF), Cost: 1.10-1.35× total payback, similar to an advance. Speed: 3-7 days. Qualification: $25K+ monthly revenue, 12+ months in business. Best for: businesses that prefer structured monthly payments over daily/weekly advance deductions. See revenue-based funding vs. loans.
• Invoice factoring, Cost: 1-5% of invoice value per 30 days (effective APR 15-60%). Speed: 1-7 days for first deal, instant for repeat. Qualification: must be B2B with invoiced customers. Best for: B2B businesses with stretched-payment customers. See MCA vs invoice factoring.
• Equipment financing, Cost: 8-25% APR. Speed: 1-7 days. Qualification: 600+ FICO, the equipment itself serves as collateral. Best for: a specific equipment purchase (HVAC unit, vehicle, machinery, etc.).
• Business credit card, Cost: 18-28% APR on revolving balance, 0% intro on some cards. Speed: instant once approved. Qualification: 660+ FICO personal credit usually required. Best for: under $15K of mixed expenses, especially if you can pay off monthly.

How to choose: the decision framework

Walk down this list and stop at the first option that fits.

1. Do you have 4+ weeks AND 680+ FICO AND clean financials? Get an SBA loan or bank line of credit. You'll pay the least.
2. Do you need under $15K and can pay it off in 30-60 days? A business credit card (especially with a 0% intro period) is cheaper than any term loan or advance.
3. Are you buying a specific piece of equipment? Equipment financing is built for this, the equipment is the collateral, rates are reasonable, qualification is easier than a general business loan.
4. Are you B2B and your customers pay you on 30/60/90-day terms? Invoice factoring may cost less than any other fast option because your invoices are the collateral.
5. Do you have ongoing variable cash-flow needs (payroll bridges, inventory cycles)? A business line of credit, if you qualify, is cheaper than a revenue-based advance over time because you only pay for what you draw.
6. Do you need money in days, not weeks, with FICO below 650 or under 2 years in business? A merchant cash advance or revenue-based financing, these are designed for time-critical needs and variable-revenue businesses. They cost more for a reason: speed and accessibility.

This order is intentional: cheapest first, fastest last. Most brokers reverse it because they make commissions on advances. Read this list as if you were giving advice to a friend.

Cheapest doesn't mean best, and most expensive doesn't mean predatory

Two honest framings small business owners rarely hear:

Cheapest isn't always best. An SBA loan at 10% APR is cheaper than an MCA at a 1.30 factor rate. But the SBA takes 60 days to fund. If you lose a customer or miss a payroll because you waited 60 days for cheap capital, the 'savings' on the rate cost you the business. The right cost is the cost that actually arrives in time.

Expensive isn't always predatory. An advance at a 1.40 factor rate is expensive because the funder is taking risk a bank won't take, funding a business with seasonal revenue, sub-650 credit, or 8 months of operating history. The price reflects the risk. What IS predatory: hidden fees, stacking encouragement, daily debits the business can't afford, undisclosed prepayment penalties, and aggressive collections. Price alone doesn't tell you whether a funder is honest, terms and behavior do.

Honest pros and cons, the short version

SBA 7(a): + lowest cost. - slow, paperwork-heavy, government-guarantee process.

Bank term loan: + low cost, predictable. - high qualification bar, slow.

Line of credit: + flexible, you only pay for what you draw. - bank version is slow to set up; online version is faster but more expensive.

MCA: + 24-48 hour funding, FICO 500+, no specific asset pledged (funders file a UCC-1 and take a performance guarantee), payment adjusts with revenue. - highest dollar cost, daily/weekly deductions can stress cash flow.

RBF: + similar to an MCA but monthly payments instead of daily, slightly cheaper for some profiles. - newer product category, fewer funders, longer underwriting than an advance.

Invoice factoring: + cost scales with actual invoice age, no fixed term, B2B-friendly. - only works if you have invoiced B2B customers, factor takes over collections.

Equipment financing: + reasonable rates, easier qualification because the equipment is collateral. - tied to a specific purchase; can't use the cash for other expenses.

Business credit card: + instant access, rewards/points, 0% intro on some. - high APR on carried balances, personal-credit dependency, low limits relative to other options.

What every funder MUST disclose before you sign

Regardless of which funding type you choose, your funder is required (by state law in many states, by best practice everywhere) to disclose these five items in writing before you sign:

1. Principal or advance amount, the exact dollar amount you're receiving.
2. Total repayment, what you'll pay back in dollars (for an advance or RBF this is fixed; for loans this is principal + interest).
3. Payment amount and frequency, your daily/weekly/monthly payment in dollars.
4. Repayment timeline, fixed term (loan) or estimated days (advance).
5. All fees, origination, processing, prepayment, ACH, default. Itemized, not bundled.

In California, New York, Florida, Georgia, Utah, Virginia, and several other states, these disclosures are required by law for non-bank commercial financing. If a funder won't put all five in writing before you sign, walk away, regardless of how attractive the headline rate looks.

Common mistakes small business owners make

Stacking advances. Taking a second advance while a first is still active. The combined daily debits often exceed what the business can sustain. Most well-run brokers refuse to facilitate stacking.

Comparing a factor rate to a loan's APR. They're not the same math. APR is time-based; factor rates aren't. See our factor rate explainer for the conversion. A direct APR comparison usually overstates the cost of a short-term advance vs a long-term loan.

Treating any funding as 'free money'. Capital is a tool. If the use of funds doesn't generate enough return to comfortably cover the repayment, the cheaper option is no funding at all.

Negotiating only the headline rate. Prepayment terms, fees, and collections behavior matter more than a 0.05 difference in factor rate. Ask about all of it.

Believing 'pre-approved' marketing. Pre-approved means a funder bought your contact data and pre-screened it. It doesn't mean an offer. Real offers come after real underwriting.

When to use Commera's calculator

Our funding calculator gives you an honest estimate range for revenue-based funding specifically, advance amount, factor rate range, daily payment, based on your monthly revenue and time in business. It's free, doesn't require an account, and doesn't run a credit check.

Use it to understand the rough shape of an advance before talking to any funder (us or anyone else). If the estimated payment looks unsustainable for your business, the right answer might be a different capital type entirely, and that's the kind of honest comparison this guide is designed to help with.

Funding guides by industry

The right funding often depends on your industry's cash-flow shape. We publish deeper, industry-specific guides that apply this same cheapest-first framework to a particular vertical:

• How to fund a landscaping or lawn care business, seasonal cash flow, equipment, and crew costs.
• Veterinary practice financing, equipment, build-outs, practice buy-ins, and working capital.
• Working capital for government contractors, bridging the 30-to-90-day government payment gap with receivables and contract financing.
• Wholesale and distribution funding, inventory and receivables financing for the double working-capital squeeze.
• How to finance an auto repair shop, the capital sources repair shops actually use.

Each one applies the same honest logic above to that industry's specific needs.
