Business Loan Calculator

Borrowing $150,000 for your business at a 9.5% rate over a 5-year term works out to about $3,150 per month. Over the life of the loan you repay roughly $189,017, of which about $39,017 is interest. Add a typical 3% origination fee ($4,500) and your total cost of borrowing climbs to about $193,517. This business loan calculator surfaces all three numbers - the monthly payment, the total interest, and the true total cost - so you can judge whether the financing actually pays for itself.

How the monthly payment is calculated

A fixed-rate term loan is repaid using the standard amortization formula:

where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments (years × 12). Early payments are mostly interest; as the balance falls, more of each payment goes to principal. The amortization table shows that shift year by year.

Why the fee changes your real cost

Lenders frequently deduct the origination fee from the funds they disburse. On the example above, you sign for $150,000 and repay $150,000 in principal, but only about $145,500 hits your account. Because you are paying interest on money you never received, your effective cost of capital is higher than the quoted 9.5%. That is why comparing the APR - which folds in fees - is more honest than comparing headline interest rates. Our APR calculator turns a rate-plus-fee quote into a single all-in number you can line up against competing offers.

Term loans vs. SBA loans vs. lines of credit

This calculator models a fixed-rate term loan: a lump sum repaid on a set schedule, the same math behind our general loan calculator and personal loan calculator. SBA 7(a) loans are bank term loans partially guaranteed by the U.S. Small Business Administration; they often carry lower rates and longer terms but add a guaranty fee and more paperwork. A business line of credit charges interest only on what you draw, so its cost depends on usage rather than a fixed payment. Use a term-loan estimate as your baseline, then adjust for the product you are actually offered.

Make the loan work harder

• Borrow only what produces a return: the loan should fund assets or activity that earns more than its cost.
• Shorten the term if cash flow allows: a shorter term sharply cuts total interest.
• Negotiate the fee: origination fees are often negotiable and directly raise your effective rate.
• Compare APR, not just rate: two loans with the same rate can cost very differently once fees are included.
• Track the interest deduction: business loan interest is generally a deductible expense under IRS rules.
• Check the payback time: if the loan funds a project, confirm the expected profit clears the total cost of borrowing - a quick break-even calculator can frame how many units or months it takes to recoup the borrowing.

How to use this calculator

You only need four inputs to get a complete picture of what a term loan will cost, and each one maps directly to a line in the results:

1. Enter the loan amount. Use the full amount you are signing for, not the cash you expect to receive. If the lender deducts the origination fee at funding, the calculator estimates your net proceeds separately.
2. Enter the annual interest rate. Use the quoted nominal rate, not the APR. The APR already bundles fees, and this tool models the fee on its own line so you can see its effect clearly.
3. Choose the term in years. Try a few terms back to back. Watch how a shorter term raises the monthly payment but lowers the total interest, and how a longer term does the reverse.
4. Enter the origination fee. Most fees fall between 1% and 6% of the loan. The calculator adds it to your total cost of borrowing and subtracts it from your net cash if it is taken at funding.

Read the results from the top down: the monthly payment tells you the recurring cash flow hit, the total interest tells you the cost of time, the total cost of borrowing rolls in the fee, and the amortization schedule shows how each year splits between interest and principal.

Who this calculator is for

This tool is built for any owner weighing a fixed-rate term loan rather than revolving credit. It fits a range of common situations:

• Founders comparing offers who have two or three term sheets with different rates, fees and terms and need an apples-to-apples cost figure.
• Owners financing equipment or expansion who want to confirm the asset will earn more than the loan costs before they sign.
• Borrowers checking affordability who need to know the monthly payment before testing it against their cash flow and existing debt.
• Anyone budgeting a buyout or working-capital loan who wants the full repayment total, not just the headline payment, in front of them.

If you draw money in pieces rather than as one lump sum, a business line of credit or a credit-card-style facility is a better match, and a fixed amortization estimate will overstate your cost.

A second worked example: a shorter, smaller loan

Say you borrow $50,000 to buy equipment at an 11% rate over a 3-year term. The monthly payment works out to about $1,637. Over the 36 payments you repay roughly $58,930, which means about $8,930 in interest. A 2% origination fee adds $1,000, pushing the total cost of borrowing to about $59,930 and leaving net proceeds near $49,000 if the fee is deducted at funding.

Now stretch the same loan to a 5-year term at the same rate. The monthly payment drops to roughly $1,087 - far easier on cash flow - but total interest climbs to about $15,227, nearly $6,300 more than the 3-year version. That trade-off is the single most important decision in any term loan: the term you choose is really a choice between monthly breathing room and lifetime cost.

Key terms explained

• Principal: the amount you borrow and must repay, separate from interest. On the main example, the principal is $150,000.
• Amortization: the process of paying off a loan in equal installments where early payments are mostly interest and later ones are mostly principal.
• Interest rate vs. APR: the interest rate sets your payment; the APR adds fees and is the truer cost-of-credit number to compare across lenders.
• Origination fee: a one-time charge, usually 1%-6% of the loan, often deducted from your disbursement so you receive less than you repay.
• Personal guarantee: a promise that you, the owner, will repay the loan personally if the business cannot.
• Collateral: business or personal assets a lender can claim if you default; secured loans usually carry lower rates than unsecured ones.
• SBA 7(a) loan: a bank loan partially guaranteed by the U.S. Small Business Administration, often with longer terms and a separate guaranty fee.

What changes the result the most

Three inputs move the numbers far more than the others, so it pays to focus your shopping and negotiation on them:

• The interest rate is the biggest lever on total interest. Even a one- or two-point difference, common between a bank loan and an online lender, can change the lifetime cost by thousands on a six-figure loan.
• The term drives the split between monthly payment and total interest. Longer terms feel cheaper each month but cost more overall; shorter terms do the opposite.
• The origination fee quietly raises your effective rate, especially on shorter loans where there is less time to spread the cost. A 5% fee on a one-year loan is far more painful than the same fee on a five-year loan.

The loan amount scales everything proportionally, while your credit profile, time in business, revenue and collateral determine which rate, fee and term a lender will actually offer you in the first place.

Limitations and assumptions

To keep the estimate clear, this calculator makes a few deliberate simplifications. It assumes a fixed rate held for the full term and a fully amortizing schedule with equal monthly payments. It does not model variable or adjustable rates, interest-only periods, or balloon loans that leave a large lump sum due at the end. It does not include prepayment penalties, late fees, packaging or closing costs, SBA guaranty fees, or insurance the lender may require. Tax effects, such as deducting interest as a business expense, are mentioned but not applied to the figures. Treat the output as a planning estimate to compare offers, not as a binding loan quote - your real terms depend on your credit, revenue, collateral and the lender you choose.

How it compares to related calculators

This page answers one question well: "what will a fixed-rate business term loan cost me each month and in total?" If your question is slightly different, a sister tool will fit better:

• For a generic loan of any kind without the origination-fee and net-proceeds breakdown, the plain loan calculator is the fastest path to a payment.
• If you are borrowing personally rather than through the business - a common route for very new companies with no credit history - the personal loan calculator uses the same math with consumer-loan framing.
• To compare two offers where one has a higher rate but lower fees, the APR calculator reduces each to a single all-in percentage.
• To see how paying extra each month or making a lump-sum payment shortens the loan and cuts interest, run the result through the loan payoff calculator.
• Before you apply, a lender will weigh your existing obligations; the debt-to-income calculator shows the ratio underwriters use, and the debt payoff calculator helps you clear existing balances first.
• To pressure-test whether the financed project earns more than it costs, the break-even calculator and the ROI calculator turn the loan into a go/no-go decision.

What lenders look at before they quote a rate

The rate, fee and term you can plug into this calculator are not numbers you pick - they are the numbers a lender offers after sizing up your business. Five factors do most of the work in that decision, and understanding them helps you anticipate the quote you will actually receive:

• Time in business: most banks and SBA lenders want at least two years of operating history; many online lenders accept six months to a year but price the added risk into a higher rate.
• Annual revenue and cash flow: lenders want to see that operating cash flow comfortably covers the new payment, often expressed as a debt-service-coverage ratio of roughly 1.25 or higher. Steady, documented revenue can offset a thinner credit file.
• Personal and business credit: the owner's personal credit usually matters as much as the business score for small loans, with the best pricing reserved for the strongest profiles.
• Collateral and guarantees: a secured loan backed by equipment, real estate or receivables typically earns a lower rate than an unsecured one, and most small business loans also require a personal guarantee from any owner with a significant stake.
• Loan purpose and type: equipment financing, working-capital lines, real-estate loans and SBA 7(a) loans each carry their own rate ranges, terms and fee structures, so the same business can be quoted very differently depending on the product.

Because of this, treat any rate you find online as a placeholder. Run a realistic estimate here, then replace the inputs with the real figures from your term sheet once a lender has reviewed your application.

Fixed vs. variable rates and short-term products

This calculator assumes a fixed rate for the whole term, which is the cleanest case to plan around. Many business loans, especially larger bank and SBA lines, instead carry a variable rate tied to a published index such as the prime rate plus a margin. When the index moves, your payment moves with it, so a variable loan that looks cheaper today can cost more over the full term if rates rise. If you are offered a variable rate, run this calculator at both the starting rate and a stress-test rate two or three points higher to see the range of payments you might face.

Short-term products deserve extra caution. Merchant cash advances and some online "term" loans quote a factor rate or a fixed total payback rather than an annual interest rate, and that total often does not shrink if you repay early. A loan advertised as costing "1.3x" the amount borrowed sounds modest until you annualize it over a few months, where it can translate into a triple-digit APR. When a quote is expressed as a flat dollar payback or a factor rate instead of a percentage, convert it to an APR before comparing it with the amortizing loan this calculator models - otherwise you are comparing two very different things.
