The interest rate is the cost of borrowing the principal alone, expressed as a yearly percentage; the APR (Annual Percentage Rate) is that same cost plus the lender's fees — origination, closing, packaging — rolled into one annualized number. Because APR bundles in the fees, it is always equal to or higher than the interest rate, and it is the more honest figure for comparing two loans side by side. If a lender quotes you a low interest rate but a much higher APR, the gap between them is the fee load — that spread is exactly what the APR was invented to expose. For a business owner weighing offers, the rule is simple: compare interest rate to interest rate, and APR to APR, and never let one lender show you a rate while the other shows you an APR.
Key takeaways
- Interest rate = the cost of borrowing the principal alone; APR = that cost plus the lender's fees, annualized into one number.
- APR is always equal to or higher than the interest rate — the gap between them is the fee load.
- On short-term loans, fees annualize harder, so a small fee can push APR well above the interest rate.
- APR was built for amortizing term loans; it's only an estimate for factor-rate products like MCAs and revenue-based financing.
- U.S. commercial financing is largely exempt from TILA's APR-disclosure rules — always ask whether a quote is a rate or an APR.
- For revenue-based products, total cost of capital and deposit holdback describe the deal better than any calculated APR.
- Revenue-based/MCA marketplace funding is approved on deposits and revenue over credit: from ~$10,000, FICO 500+, decisions in 24-48 hours; never guaranteed.
The core distinction, in one line each
Interest rate answers: what does the borrowed money itself cost per year? It's applied to your outstanding principal and nothing else. A $100,000 loan at a 10% interest rate accrues interest on that balance as you carry it.
APR answers: what does the entire financing arrangement cost per year once the lender's fees are folded in? It takes the interest and the mandatory fees, spreads them across the loan term, and re-expresses everything as a single annualized percentage. That's why two loans with an identical 10% interest rate can carry very different APRs — one might charge a 2% origination fee and the other 6%.
Put plainly: the interest rate is a component; the APR is the all-in price. In the U.S., the Truth in Lending Act (TILA) requires consumer lenders to disclose APR precisely so borrowers can compare the true cost. Business financing is not covered by TILA the same way, which is exactly why APR discipline matters more, not less, when you're borrowing for a company — nobody is legally required to hand you the honest number.
Why APR is almost always the higher number
APR starts with the interest rate and then adds cost on top. The fees that typically get pulled into APR include origination or underwriting fees, packaging or documentation fees, and any mandatory closing costs. It generally does not include optional, third-party, or contingent charges — late fees, prepayment penalties you may never trigger, or optional insurance.
The size of the gap between rate and APR is a fee gauge. A tight gap means low fees. A wide gap means the headline rate was hiding a heavy fee load. Watch this especially on short terms: a flat fee spread over 6 months annualizes into a much bigger APR bump than the same fee spread over 5 years, because APR is a per-year figure. A modest-looking fee on a short-term product can push the APR well above what the interest rate suggested.
A side-by-side example
These figures are illustrative — for example only — to show how the same interest rate produces different APRs once fees and term enter the picture. No offer is implied.
| Offer | Interest rate | Origination fee | Term | Resulting APR (approx.) |
|---|---|---|---|---|
| Loan A | 10% | 2% | 5 years | ~11% |
| Loan B | 10% | 6% | 5 years | ~13% |
| Loan C | 10% | 4% | 1 year | ~18% |
The takeaway: Loan A and Loan C share the same 10% interest rate, but Loan C's shorter term makes its fee bite harder on an annualized basis, so its APR runs far higher. If you compared these three on interest rate alone, they'd look identical. APR is what separates them.
Where APR breaks down: fixed-fee and revenue-based products
APR was built for term loans with a stated interest rate and a repayment schedule. It gets awkward — and sometimes misleading — for products that don't work that way. Merchant cash advances and revenue-based financing don't charge an interest rate at all. They use a factor rate (a multiplier like 1.25 or 1.40 applied to the amount advanced) and repay as a fixed percentage of your daily or weekly deposits.
Because there's no principal-and-interest amortization, and because repayment speed floats with your sales, any APR you calculate is an estimate that depends entirely on how fast you repay. Pay it off quickly and the implied APR is high; stretch it out as revenue dips and the implied APR falls. Some brokers quote an APR anyway to force a comparison, but the number moves with your cash flow. For these products, the more useful questions are: what's the total cost of capital, what percentage of daily deposits gets held back, and how does that holdback sit against your real cash-flow rhythm?

Decision framework: which number to lean on, and when
Lean on APR when:
- You're comparing two or more term loans with stated interest rates — APR is the only apples-to-apples figure.
- Fees are involved and you want to know the real, all-in annual cost.
- Terms differ between offers — APR normalizes for term so a short loan and a long loan can be compared honestly.
Lean on interest rate (plus a separate fee review) when:
- You're looking at how interest accrues on a line of credit you'll draw and repay irregularly, where APR assumes a full-term draw you may not use.
- You want to isolate the pure cost of money from the fee structure to negotiate each separately.
Set both aside and look at total cost of capital + holdback when:
- The product is a merchant cash advance or revenue-based financing priced on a factor rate — an APR here is a moving estimate, not a fixed fact.
- Your real constraint is cash-flow timing, not the annualized percentage — what matters is whether the daily or weekly remittance leaves enough working capital in the account.
How revenue-based funding gets priced instead
If your business has been declined on rate-and-APR products because of credit, or you simply need capital faster than a term-loan close allows, revenue-based financing works on a different axis entirely. A revenue-based or MCA marketplace approves largely on your bank deposits and revenue history rather than your credit score — underwriting reads the last several months of statements to size an advance against real cash flow.
Typical shape of these programs: funding from around $10,000 and up, FICO 500+ considered, and decisions in roughly 24 to 48 hours because the review centers on deposits, not a lengthy credit file. Pricing is a factor rate with a deposit-based holdback, so instead of asking "what's my APR," you're asking "can my weekly cash flow absorb this remittance and still cover payroll and inventory?" That's the right question for this product. Approval is never guaranteed — it depends on what the statements actually show — but the deposit-first approach opens a door that rate-and-APR lenders often close on credit alone. You can see how the intake works on our revenue-based funding application.
Five questions to ask any lender about pricing
- Is this an interest rate or an APR? If you can't get a straight answer, treat the quote as the interest rate only and assume fees on top.
- What fees are included in the APR, and what's excluded? Origination and closing usually count; late and prepayment penalties usually don't.
- Is there a prepayment penalty or a minimum interest charge? Some products bake in the full cost of capital even if you repay early — meaning early payoff saves you nothing.
- For factor-rate products: what's the total cost of capital and the holdback percentage? These two numbers describe the deal better than any estimated APR.
- What happens to my cost if revenue slows? On amortizing loans the payment is fixed; on revenue-based products the remittance flexes with deposits.
Frequently asked questions
Is a lower interest rate always the cheaper loan?
No. A loan with a lower interest rate but heavier fees can cost more overall than one with a slightly higher rate and minimal fees. The APR captures that difference by folding fees into a single annualized number, which is why you compare APR to APR rather than rate to rate.
Why is the APR higher than the interest rate on my offer?
Because APR includes the lender's fees on top of the interest — origination, packaging, and closing costs, annualized across the term. The wider the gap between your interest rate and your APR, the heavier the fee load. A small gap signals low fees; a large gap signals the headline rate was hiding cost.
Can the interest rate and APR ever be the same?
Yes — when there are no fees. If a loan charges no origination or closing costs, there's nothing extra for the APR to absorb, so the two numbers match. In practice that's rare in business lending, so expect the APR to run at least somewhat higher.
Does APR apply to merchant cash advances or revenue-based financing?
Not cleanly. Those products use a factor rate and repay as a percentage of your deposits, not principal-plus-interest on a schedule. Any APR quoted on them is an estimate that shifts with how fast you repay. For these, look at total cost of capital and the holdback percentage against your cash flow instead.
Which number matters more for a short-term loan?
APR — and it matters more on short terms than long ones. A flat fee spread over a few months annualizes into a much larger APR bump than the same fee over several years. Two short-term offers with identical interest rates can carry very different APRs once term and fees are accounted for.
How do I compare a term loan against a revenue-based advance?
You can't do it on APR alone, because the advance isn't priced on an interest rate. Compare the term loan's APR and monthly payment against the advance's total cost of capital and deposit holdback, then judge each against your actual cash-flow timing — how much working capital stays in the account after each payment or remittance.
Is business financing required to disclose APR like a consumer loan?
Generally no. The Truth in Lending Act requires APR disclosure on most consumer credit, but commercial financing is largely exempt (a handful of states now require some disclosure). That's precisely why you should ask directly whether a quote is a rate or an APR, and what fees are baked in — nobody is federally obligated to hand you the all-in number.
Can I qualify for revenue-based funding with a low credit score?
Often yes. A revenue-based or MCA marketplace underwrites primarily on bank deposits and revenue, with FICO 500+ commonly considered, funding from around $10,000, and decisions typically in 24 to 48 hours. Approval is never guaranteed — it depends on what your statements show — but the deposit-first approach can clear applicants that rate-and-APR lenders decline on credit.
