Understanding Business Financing: Which Type Do You Actually Need?
"Business loan" covers a wider range of products than almost any other financing category, and picking the wrong one costs real money. A term loan — a lump sum repaid on a fixed schedule — is the right tool for a one-time purchase or expansion. An SBA 7(a) loan is a government-guaranteed version of the same thing, trading a slower approval process and an upfront guarantee fee for a meaningfully lower rate and longer term. A business line of credit behaves more like a credit card: a revolving limit you draw against and repay as needed, better suited to smoothing out uneven cash flow than funding a single large purchase. Equipment financing uses the equipment itself as collateral, which typically unlocks lower rates than an unsecured loan of the same size. A merchant cash advance isn't a loan at all — it's a sale of a slice of your future revenue for cash today, priced completely differently from everything else on this list. The three tabs on this page are built around the three questions that actually determine which of these fits: what will it cost, how much can you actually get approved for, and — if an MCA is on the table — what does it really cost once you see past the factor rate.
How This Calculator Works
The Loan Payment tab uses the standard fixed-payment amortization formula — the same math underlying every term loan, SBA loan, and equipment loan, with P as the amount financed, r as the monthly interest rate, and n as the number of monthly payments:
Toggle "I know my target payment" to run the same formula in reverse — enter what you can afford to pay each month, and it solves for the maximum loan amount that produces that payment, accounting for whatever fees apply. True APR is solved the same way every APR figure on this site is solved: it finds the rate that would produce your actual payment if calculated on the amount you actually walk away with (loan amount minus any upfront fee, or loan amount plus a financed fee, depending on which you choose) — which is why APR is always at least slightly higher than the stated interest rate whenever any fee is involved at all.
Two more fields extend this same math. Adding an amount in "Extra monthly payment" re-runs the amortization with that much more going toward principal every month, and shows exactly how much sooner you're done and how much interest that saves — useful for deciding whether to accelerate payoff once cash flow allows it, without needing to ask a lender or run your own spreadsheet. Checking "Compare to a second loan offer" (available whenever you're solving from a known loan amount) runs the identical calculation a second time against a different rate, term, and fee total, and tells you which one actually costs less over its full term — not just which has the lower headline rate, which are frequently two different answers once term length is factored in.
SBA 7(a) Loans: Rates, Fees, and How They Really Work
SBA 7(a) loans carry an upfront guarantee fee charged on the government-guaranteed portion of the loan (75% for loans over $150,000, 85% at or below that), not the full loan amount. For FY2026, that fee is tiered: 2% of the guaranteed portion for loans of $150,000 or less, 3% for loans from $150,001 to $700,000, and 3.5% on the guaranteed portion up to $1 million plus 3.75% on any guaranteed amount above that for larger loans. Check the "This is an SBA 7(a) loan" box above to have this calculated automatically from your loan amount. Manufacturers (NAICS sectors 31-33) get the fee waived entirely on loans of $950,000 or less as of FY2026 — check the manufacturing box if that applies to you. The fee is typically financed into the loan balance rather than paid out of pocket, which the calculator lets you toggle either way. There's also an annual service fee, but that's paid by the lender to the SBA, not billed to you directly, so it doesn't change your payment and isn't included in the calculation above.
What you get in exchange for the fee and the paperwork: SBA 7(a) rates typically run noticeably below a comparable bank term loan, with terms stretching up to 25 years for real estate versus the 5-10 years typical of conventional bank financing, and loan amounts up to $5 million. The trade-off is speed — expect 4-8 weeks from application to funding, versus same-week for many online lenders.
Debt Service Coverage Ratio: The Number That Actually Decides Your Loan
Most business owners fixate on the interest rate. Most commercial lenders fixate on Debt Service Coverage Ratio (DSCR) instead — it's the actual number that determines whether you get approved and for how much, regardless of how attractive the advertised rate looks.
A DSCR of 1.0 means your business generates exactly enough cash to cover its debt payments with nothing left over — which is exactly why virtually no lender will accept it. 1.25 is the most commonly cited minimum, meaning your business needs to generate 25% more net operating income than its total debt service requires. Some lenders will go as low as 1.15-1.20 for otherwise strong borrowers; more conservative lenders, or riskier industries, may require 1.35 or higher. The DSCR Affordability tab above works this backward from the number that matters: given your net operating income and existing debt, it tells you the maximum new loan payment — and therefore the maximum new loan amount — that keeps you at or above your target ratio, which is a genuinely different (and usually more binding) number than "how much loan do I want."
Merchant Cash Advances: Why the Factor Rate Isn't the Real Cost
A merchant cash advance is quoted with a factor rate — a number like 1.30 that you multiply directly by the advance to get your total payback ($50,000 advanced at a 1.30 factor rate means $65,000 owed back, full stop, regardless of how long repayment takes). No interest rate is quoted at all, which is exactly what makes MCAs hard to compare against an actual loan. The simplest conversion — annualizing the cost of capital over the repayment period — already produces a number that looks steep. But it understates the real cost, because remittances typically start the very next business day: you never get the use of the full advance for the whole term the way you would with a loan that only requires interest payments along the way. Accounting for that (the same way this site solves for APR on any loan with a payment schedule) consistently produces a materially higher effective annual rate than the simple calculation alone — often well past 100%, even at factor rates that look moderate on paper. The Merchant Cash Advance tab above shows both numbers side by side specifically so the gap between "what it looks like" and "what it actually costs" is visible before you sign anything.
Comparing Loan Types Side by Side
| Type | Typical Rate | Speed | Best For |
|---|---|---|---|
| SBA 7(a) | ~9.75%–14.75% + guarantee fee | 4-8 weeks | Established businesses, larger amounts, longest terms |
| Bank Term Loan | ~6.8%–11% | 1-4 weeks | Strong financials, existing banking relationship |
| Online Term Loan | ~14%–45%+ | 1-3 days | Speed, thinner credit files, smaller amounts |
| Business Line of Credit | ~8%–35% | Days to weeks | Uneven cash flow, ongoing working capital |
| Equipment Financing | ~4%–45% | Days to weeks | Vehicles, machinery — equipment secures the loan |
| Merchant Cash Advance | 1.1–1.5 factor (often 100%+ true APR) | Same day to days | Urgent cash need when other options aren't available |
The pattern holds across almost every category: the faster the funding and the lower the qualification bar, the higher the cost. Matching the loan type to how urgently you actually need the money — rather than defaulting to whichever option responded first — is usually worth more than any amount of rate-shopping within a single category.
What Lenders Actually Look At
Beyond DSCR, five factors drive both approval and pricing on nearly every application: personal and business credit score (banks and SBA lenders typically want 680+; online lenders are more flexible but price the difference into the rate), time in business (2+ years opens meaningfully more doors and better pricing), annual and monthly revenue (steadier, stronger revenue lowers perceived risk), industry (some sectors are flagged as higher-risk by underwriting models regardless of an individual business's performance), and collateral (secured loans consistently price lower than unsecured ones for the same borrower). A personal guarantee — making you personally liable if the business itself can't repay — is standard on nearly every small business loan under roughly $500,000 to $1 million, SBA loans included, regardless of the business's own legal structure.
Lenders also want to see that the business clears its costs at a realistic volume, not just that the repayment fits. Our break-even calculator works out the units and revenue needed to cover a fixed cost base including the new repayment.
Fixed vs. Variable Rate Business Loans
A fixed-rate loan locks in the same rate for the entire term — what you calculate today is what applies in year 5 or year 10. A variable-rate loan (common with SBA 7(a) loans, many bank lines of credit, and some online lenders) is tied to an index like the Prime Rate plus a lender-set margin, so the rate — and your payment — can move if that index moves. Variable loans often start slightly lower than an equivalent fixed-rate offer, which is the trade-off: a lower cost today in exchange for not knowing exactly what you'll pay in year 5. If you're using this calculator on a variable-rate loan, treat the rate you enter as a snapshot of today's pricing rather than a permanent number, and re-check the calculation if the underlying index moves meaningfully.
What This Calculator Doesn't Cover
This tool estimates payment, true cost, and lender-style affordability for standard fixed-rate financing — it doesn't replace an actual lender's underwriting, which weighs qualitative factors (industry risk, management experience, collateral quality) this calculator can't see. It doesn't model prepayment penalties (some SBA loans with terms over 15 years carry one during the first three years), doesn't handle the SBA 504 program's three-party structure (a bank loan, a CDC/SBA-backed second loan, and your down payment, each with different rates), and doesn't simulate a variable rate's future path — it treats whatever rate you enter as fixed for the full term you specify. It also doesn't factor in state-level licensing rules or usury caps that can apply to certain lender types in certain states. Treat every figure here as a planning estimate to bring into a conversation with an actual lender or accountant, not a substitute for one.
Frequently Asked Questions
What credit score do I need for a business loan?
Banks and SBA lenders typically want a personal credit score of 680 or higher, though individual lenders set their own minimums. Online lenders are often more flexible and will work with scores in the 600s, but charge meaningfully higher rates to offset that risk.
What's the difference between an interest rate and APR on a business loan?
The interest rate is the cost of borrowing the principal alone, and it's what your payment is actually calculated on. APR layers in required fees (like an SBA guarantee fee or origination fee) spread over the loan term, giving you the true annual cost — which is why APR is the right number for comparing two different loan offers, even though your payment is based on the interest rate.
What is a good debt service coverage ratio (DSCR) for a business loan?
Most lenders want to see a DSCR of at least 1.25, meaning your business generates 25% more net operating income than it needs to cover all debt payments, including the new loan. Some lenders accept 1.15-1.20 for strong borrowers, while more conservative lenders may require 1.35 or higher.
How is a merchant cash advance different from a business loan?
A merchant cash advance isn't technically a loan — it's a sale of a portion of your future receivables in exchange for an upfront advance, priced with a factor rate (like 1.30) instead of an interest rate. There's no APR quoted upfront, remittances are usually daily or weekly, and the true annualized cost is often dramatically higher than the factor rate alone suggests once you account for how quickly it's repaid.
Should I choose an SBA loan or a bank term loan?
SBA loans generally offer lower rates and longer terms than a comparable bank loan, but come with an upfront guarantee fee, more paperwork, and a slower funding timeline (often 4-8 weeks). A conventional bank term loan can fund faster with fewer fees if your business already qualifies for the bank's best rates, but usually caps out at shorter terms and lower amounts than SBA financing allows.
How much can my business actually borrow?
It depends on which constraint binds first: your desired loan amount, or the maximum a lender will actually approve based on your business's debt service coverage ratio at their required minimum (commonly 1.25). The DSCR Affordability tab above estimates that second number directly from your net operating income and existing debt payments.
Should I make extra payments on my business loan?
If your loan has no prepayment penalty and the cash is genuinely spare rather than needed elsewhere in the business, extra payments reduce total interest and shorten the term with no downside — the Loan Payment tab's "Extra monthly payment" field shows exactly how much of each. The more common mistake is directing spare cash toward a low-rate loan instead of a higher-rate one (like a credit card or MCA) that would save more per dollar redirected.
How do I compare two loan offers?
Check "Compare to a second loan offer" on the Loan Payment tab, enter Offer B's rate, term, and total fees, and the calculator runs both through the same math to show total cost side by side. The lower headline rate doesn't always win — a shorter term or lower fees on the other offer can make it cheaper overall even at a higher rate, which is exactly the kind of comparison that's easy to get wrong by eyeballing two rate quotes alone.
