Financing a business: payment, fees, and true cost
A business term loan is repaid on a fixed amortizing schedule, so the headline rate alone rarely tells you what the money really costs. An origination fee quietly raises your effective rate, and the term you choose determines how much interest stacks up over the life of the loan. This calculator pulls all of that together — the monthly payment, total interest, the fee-inclusive APR, and a payment-by-payment schedule — so you can weigh offers on equal footing. For an SBA 7(a) loan specifically, the SBA loan calculatormodels the SBA guarantee fee as well.
The loan payment formula
M = P · [ i(1 + i)n ] / [ (1 + i)n − 1 ]
i = monthly rate, n = number of payments. The APR shown is solved so the present value of all payments equals the cash you actually receive after the origination fee.
What makes this calculator different
- True APR with origination fees. We fold the origination fee into the math and solve for the effective APR — the only fair way to compare one lender’s offer against another’s.
- Full amortization schedule. See every payment broken into principal and interest, and watch the balance burn down to zero.
- Extra-payment savings. Add an extra amount each month to see how much sooner the loan is paid off and how much interest you keep in the business.
Frequently asked questions
How is a business loan payment calculated?+
A fixed-rate business term loan amortizes just like any other instalment loan: the payment is solved so the loan is fully paid off by the end of the term. The formula is M = P · i(1 + i)ⁿ / ((1 + i)ⁿ − 1), where P is the amount borrowed, i is the monthly interest rate, and n is the number of monthly payments. Each payment covers that month’s interest first, with the remainder reducing your principal, so early payments are interest-heavy and later ones pay down more balance. This calculator runs that math and shows the full schedule.
What are typical business loan interest rates and terms?+
Business loan rates and terms vary widely by lender, your credit and time in business, the loan type, and whether it’s secured. Bank and SBA-backed term loans tend to carry lower rates and longer terms, while online lenders and short-term products price higher for faster, less-restrictive funding. Terms commonly range from one to a handful of years for working-capital loans, and longer for equipment or real-estate financing. Because pricing moves with the market and your profile, treat any single number as a rough benchmark and get real quotes before deciding.
What fees do business loans charge?+
The most common up-front charge is an origination fee, typically a percentage of the loan that is deducted from your proceeds or added to the balance. You may also see underwriting, packaging, or closing fees depending on the lender and loan type. Because these costs raise what you effectively pay without changing the headline note rate, the APR — which folds fees into a single annualized cost — is the number that lets you compare lenders honestly. This calculator computes that fee-inclusive APR for you.
What’s the difference between a term loan and a line of credit?+
A term loan gives you a lump sum up front that you repay on a fixed schedule, which makes it well suited to one-time investments like equipment or expansion. A line of credit instead lets you draw, repay, and redraw up to a limit, and you generally pay interest only on what you’ve actually borrowed. Lines of credit are better for fluctuating or short-term needs such as covering payroll gaps or seasonal inventory. This calculator models the term-loan case, where the borrowed amount amortizes to zero over a set period.
How do lenders decide how much to lend a business?+
Lenders focus heavily on cash flow — whether the business reliably generates enough income to cover the new payment on top of existing obligations. A common test is the debt service coverage ratio (DSCR), which compares net operating income to total debt payments; most lenders want comfortably more than 1.0. They also weigh the owner’s and business’s credit, time in business, revenue, collateral, and any personal guarantee. Stronger cash flow and credit generally unlock larger amounts, lower rates, and longer terms.
