To compare interest rates on business financing accurately, convert every offer to the same yardstick, annual percentage rate (APR), and then check it against your cash flow, because a "rate" alone hides fees, term length, and payment frequency. A bank term loan quoted at 11% APR, an SBA loan at prime-plus, a line of credit with a draw fee, and a revenue-based advance quoted as a factor rate are four different pricing languages. Until you translate them into one common cost figure and match them to how your revenue actually arrives, you are comparing a monthly payment to a weekly one to a fixed fee, and the "lowest rate" on the page frequently turns out to be the most expensive money you can borrow.
Key takeaways
- Compare every offer on APR and total finance charge, not the headline rate, since fees, term, and payment frequency change the real cost.
- A factor rate is not an interest rate: a factor of 1.25 means 25 cents on the dollar in charges, and it can't be compared to an APR without converting both to the same basis.
- The lowest rate you can't qualify for, or can't wait weeks for, is not a real option, approval odds and timing are part of the true cost.
- Bank and SBA loans offer the lowest APRs but need strong credit (roughly 680+), longer timelines, and full documentation.
- Revenue-based / MCA-marketplace financing underwrites on bank deposits and revenue (FICO 500+), funding roughly $10,000 and up in 24-48 hours.
- Watch for origination, packaging, draw, servicing, and prepayment terms, they often sit outside the quoted rate but drive the total cost.
- No legitimate funder guarantees approval or a specific rate before underwriting your file.
Rate vs. APR vs. total cost of capital, three numbers that are not the same
Most owners shop on the headline rate. Underwriters shop on total cost of capital. Here is the difference that matters:
- Interest rate is the periodic charge on the outstanding balance. It ignores origination fees, packaging fees, draw fees, and prepayment terms.
- APR (annual percentage rate) folds most fees into an annualized figure, which is why it is the only apples-to-apples comparison across loan types. A 9% rate with a 4% origination fee on a one-year term is not a 9% cost.
- Total cost of capital is the plain-language answer to "how much extra does this money cost me over the life of the deal," expressed as cents on the dollar or as the sum of finance charges. On short-term products this is the number that governs your decision.
A factor rate, common on revenue-based financing and merchant cash advances, is not an interest rate at all. A factor of 1.25 means you repay 25 cents on the dollar in finance charges, but because the term is short and payments are frequent, the equivalent APR can look dramatically higher than a bank loan while the actual dollars out of pocket are smaller. That is why you never compare a factor rate directly against an APR without converting both to the same basis.
How to convert any offer to a comparable basis
Run every offer through the same three steps before you rank them:
- List the all-in finance charge. Add origination, packaging, underwriting, and draw fees to the interest or the factor-based charge. Fees financed into the balance still count.
- Anchor to the term. A 15% total cost over 18 months is cheaper capital than a 15% total cost over 6 months. Term length is half of the comparison.
- Normalize the payment frequency. Daily and weekly remittances hit cash flow differently than a monthly payment, even at an identical stated cost. Frequent small payments can be easier to absorb during steady sales and harder during a slow stretch.
Once you have all-in charge, term, and frequency for each offer, you can rank them honestly. Skip any step and you are guessing. For a deeper walkthrough of the pricing math, see our pillar guide on the true cost of a business loan.
Example rate comparison table
The figures below are illustrative, for example only, to show how the same $50,000 need prices out across product types. They are not quotes and not guaranteed. Your actual terms depend on your revenue, deposits, time in business, and credit profile.
| Product (for example) | How it's priced | Typical term | Payment cadence | Speed to funding | Best fit |
|---|---|---|---|---|---|
| Bank term loan | ~8%-13% APR + origination | 3-7 years | Monthly | 2-6 weeks | Strong credit, patient timeline |
| SBA 7(a) | Prime + spread | 10-25 years | Monthly | 30-90 days | Lowest cost, heavy paperwork OK |
| Business line of credit | ~10%-24% APR + draw fees | Revolving | Monthly on draws | 1-10 days | Ongoing, unpredictable needs |
| Revenue-based / MCA marketplace | Factor rate (e.g. 1.15-1.45) | 3-18 months | Daily or weekly, tied to sales | 24-48 hours | Fast, revenue-qualified, thin or bruised credit |
Notice that the product with the highest equivalent APR (revenue-based financing) can still be the right call when speed or approval odds decide whether you capture the opportunity at all. The cheapest rate you cannot get approved for, or cannot wait 60 days for, is not a real option.
Why the lowest rate is often the wrong comparison
Rate shopping fails owners in three predictable ways. First, approval reality: a 9% bank rate is meaningless if your credit or time in business gets you declined, so it should never anchor your expectations. Second, timing: a slower, cheaper loan that funds after the equipment auction, the bulk-inventory window, or the payroll deadline has passed costs you the opportunity, which rarely shows up in any rate. Third, fee stacking: a low rate paired with a 5% origination fee, a draw fee, and a prepayment penalty can cost more than a higher rate with none of those. Always compare the finance charges you will actually pay, not the number printed largest on the term sheet.
Decision framework: which rate structure fits your situation
An APR-priced bank or SBA loan works best when:
- You have solid personal and business credit (typically 680+) and two-plus years in business.
- Your use of funds is long-lived, such as real estate, a build-out, or a multi-year expansion.
- You can wait weeks to months and produce full financials, tax returns, and a business plan.
A line of credit works best when:
- Your need is recurring and hard to size in advance, like seasonal inventory or gap financing between receivables.
- You want to pay for capital only when you draw it.
Revenue-based / MCA-marketplace financing works best when:
- You need funds in 24-48 hours and cannot wait out a bank timeline.
- Your credit is thin or bruised (FICO 500+) but your bank deposits and revenue are healthy, since approval leans on cash flow, not just the credit score.
- You need at least ~$10,000 and can service payments from steady daily or weekly sales.
Avoid revenue-based financing when: your margins are too thin to absorb frequent remittances, your sales are highly erratic with long dry spells, or you have the credit and the time to qualify for materially cheaper APR-priced capital. The tool is built for speed and access, not for being the lowest headline number.
How a revenue-based marketplace changes the comparison
If a bank rate is out of reach or too slow, the relevant comparison is not "advance vs. bank loan", it is "advance vs. the cost of not acting." A revenue-based financing marketplace underwrites primarily on your bank deposits and revenue rather than credit alone, which is why owners with a FICO in the 500s and no time for a bank package still get approved. Because a marketplace shops your file across multiple funders instead of one, you see competing offers side by side and can rank them on total finance charge, term, and remittance cadence, exactly the framework above. Funding typically lands in 24-48 hours on amounts starting around $10,000. No legitimate funder guarantees approval or a specific rate, so treat any "guaranteed" pitch as a red flag. For how these approvals actually work, see our pillar on revenue-based business financing.
Questions to ask before you sign any offer
- What is the all-in cost in dollars and cents on the dollar? Not just the rate.
- What fees are added or financed? Origination, packaging, underwriting, draw, servicing.
- What is the term and the payment frequency? Monthly, weekly, or daily, and how it maps to your revenue.
- Is there a prepayment benefit or penalty? On short-term products, early payoff sometimes reduces the finance charge and sometimes does not.
- Does the remittance flex with sales? Some revenue-based structures adjust to your deposit volume, which protects cash flow in slow weeks.
- Are there stacking or double-funding restrictions? Taking a second position without disclosure can breach your agreement.
Get every answer in writing on the term sheet before you accept. A funder that will not put the all-in cost in plain language is telling you something.
Frequently asked questions
What's the difference between interest rate and APR on a business loan?
The interest rate is the periodic charge on your outstanding balance. APR annualizes that rate plus most fees, so it reflects the true yearly cost of the money. Two loans with the same interest rate can have very different APRs once origination and packaging fees are included, which is why APR is the fairer comparison across lenders.
How do I compare a factor rate to an APR?
You can't compare them directly, because a factor rate is a flat multiplier on the amount funded, not an annualized charge. To compare, convert both offers to the same basis: total finance charge in dollars, the term length, and the payment frequency. A factor of 1.25 means 25 cents on the dollar in charges, but the equivalent APR depends heavily on how short the term is.
Why is the lowest rate not always the cheapest financing?
Because a low rate can carry high fees, a short term, or a prepayment penalty that push the real cost above a higher-rate offer. And a cheap rate you can't qualify for, or one that funds too slowly to catch your opportunity, has no value. Compare total cost of capital and timing, not just the headline number.
What credit score do I need to get the lowest business loan rates?
The lowest APR bank and SBA rates generally go to owners with roughly 680+ personal credit and two or more years in business, plus full financials. If your score is lower, revenue-based options that underwrite on bank deposits and revenue (FICO 500+) can still approve you, though at a higher equivalent cost that reflects the added risk and speed.
How is revenue-based financing priced compared to a bank loan?
Revenue-based financing is usually priced as a factor rate rather than an APR, repaid through daily or weekly remittances tied to your sales over a short term. The equivalent APR often looks higher than a bank loan, but the actual dollars out of pocket can be smaller, and approval speed (24-48 hours) and looser credit requirements are the tradeoff you're paying for.
Should I take a higher-rate offer if it funds faster?
Sometimes, yes. If a slower, cheaper loan funds after your opportunity closes, such as an inventory buy, an equipment auction, or a payroll gap, the faster money is the rational choice even at a higher rate. Weigh the extra finance charge against the cost of missing the opportunity entirely.
What fees should I watch for when comparing offers?
Look for origination, packaging, underwriting, draw, and servicing fees, plus any prepayment penalty. These often don't appear in the quoted rate but materially change the total cost. Ask every funder for the all-in cost in dollars and cents on the dollar, in writing, before you accept.
Does any lender guarantee approval or a specific rate?
No legitimate lender or marketplace guarantees approval or a fixed rate before reviewing your bank deposits, revenue, and profile. Any pitch promising a guaranteed rate or guaranteed approval is a red flag. Reputable funders quote a range and finalize terms only after underwriting your actual file.
