Interest rate versus APR on a business term loan
The interest rate prices the balance. The APR is meant to price the whole deal, and on business credit nobody is forced to agree what that includes.

What is the difference between the interest rate and the APR on a business loan?
The interest rate is what accrues on the outstanding balance; the APR is meant to express the total cost of credit, including fees, as an annualised rate on the money you actually received. Illustrative only — $100,000 over 60 months at a 10% nominal rate has a payment of $2,124.70 and $27,482.00 of interest, but a $3,000 fee deducted at funding lifts the effective annualised cost to 11.32%. On business credit there is no federally standardised APR, so compute it yourself from the cash and the schedule.
What each one measures
The interest rate is applied to the balance you still owe. It determines the payment and how the payment splits between interest and principal.
The APR is meant to express everything the credit costs — interest plus the fees treated as part of the finance charge — as an annualised rate on the money you actually received.
If there are no fees and no timing quirks, they are the same number. Fees are what separate them.
Worked
Illustrative only — $100,000 over 60 monthly payments at a 10% nominal annual rate.
The monthly rate is 0.8333%, the payment is $2,124.70, and you repay $127,482.00, so interest is $27,482.00. Quoted as an interest rate, this loan is 10%.
Now deduct a $3,000 origination fee at funding. You received $97,000, the payments are unchanged, and the rate that discounts them back to $97,000 — multiplied by twelve — is 11.32%. That is the APR.
The gap is 1.32 percentage points, and it is all fee.
A third number, which is neither
Compounding the 10% nominal rate monthly gives an effective annual rate of 10.47%. This is not the APR, it is the same interest rate expressed under a different convention. Three legitimate figures — 10%, 10.47%, 11.32% — describe one loan, and a comparison that mixes conventions is not a comparison.
Why this is looser on business credit than you would expect
Regulation Z standardises what belongs in a consumer APR. It does not apply to credit extended primarily for business, commercial or agricultural purposes — see 12 CFR 1026.3(a). Two business lenders can therefore include different charges in their APRs without either being wrong. New York's Commercial Finance Disclosure Law and California's commercial financing disclosure regulations do prescribe disclosures, including an APR or estimated APR, for covered transactions; check whether yours is covered.
Where the fee sits barely matters. When you exit does.
Four hundredths of a percentage point. The structure people argue about is close to irrelevant; the fee itself is what moved the number.
Now change something that does matter. Keep the fee deducted at funding and repay the loan at the end of month 24, when the balance is $65,847.22. The realised annualised cost over that shorter life is 12.00%, not 11.32%, because the $3,000 was paid once at the start and has been spread across two years instead of five.
The rule that gives you: a quoted APR assumes you run the full term. If you expect to refinance or sell before maturity, a fee-heavy loan is more expensive than the quote, and the gap widens the earlier you leave.
Payment frequency is part of the price
The same 10% over the same five years, paid weekly rather than monthly, is 260 payments of $489.11 against 60 payments of $2,124.70. Total repaid: $127,168.85 weekly against $127,482.27 monthly.
The weekly version costs marginally less in total because principal reduces sooner. It also removes about $1,635 from the account in four or five instalments rather than one, which is a cash management fact rather than a pricing one. When a quote changes frequency, check both — what it does to the total, and what it does to the week a large supplier payment falls due.
What moves a floating quote
If the note floats, the number you were quoted is an index plus a margin on the day you were quoted. Three questions settle what you have actually agreed to.
- Which index, and how often does it reset? Daily, monthly and quarterly resets behave very differently in a moving market.
- Is there a floor? A rate floor means the margin is your best case and the index can only move against you.
- Does a rise hit the payment or the term? Some agreements hold the payment and extend the maturity; others reset the payment. The first is easier on cash flow and more expensive in total.
Two more places the numbers diverge
Ask for both in dollars before closing: the odd-days interest, and the exact amount that will leave or fail to arrive on the funding date. Those two figures are the difference between the loan you modelled and the cash you actually get.
What to ask for
- The note rate and whether it is fixed or floating, and over what index.
- Every fee in dollars, and whether it is deducted at funding or added to the balance.
- The full payment schedule.
- The APR the lender quotes, and specifically what it includes.
Then do it yourself: solve for the periodic rate on the cash received and the schedule, and multiply by periods per year. The calculators will run it. If your figure and theirs differ, the difference is a list of charges, and that list is the thing to discuss.

Which funding products does this apply to?
Term Loan, Business Line of Credit, SBA Loan, Equipment Financing. Each has its own page listing the funders in this directory that offer it and what each one publishes about its terms.
Are the figures here quotes?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What a particular lender charges is on that lender's page, where it publishes it at all.
Who writes this?
The Find Me Funders research desk. Some drafting is AI-assisted, and every page that is says so at the top, including whether a person has checked its claims yet.
How do I know a figure here is right?
Where a page carries the green notice, its claims were checked against the sources listed at the end and a reviewer is named. Where it carries the amber one, nobody has verified it yet and you should confirm anything you plan to act on.
Are the examples real deals?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What any particular lender charges is on that lender's page, where it publishes it.
Why do you never say what a typical rate is?
Because we cannot source it. A market average assembled from lenders who do not publish prices is a guess with a decimal point on it. Where a lender publishes a figure, we show that figure and say where it came from.
Is this financial or legal advice?
No. It is general information about how these products work. Outcomes depend on your contract and your state, and a lawyer or accountant licensed where you are is the person to ask about your situation.
