Securing a business loan is a common way for companies to fund expansion, purchase inventory, purchase equipment, or manage cash flow. Unlike consumer loans, commercial financing option terms can be highly customized, featuring different payment frequencies, variable interest rates, and upfront fees. Calculating your debt service capacity is critical to ensure that your business remains profitable and liquid.
Most commercial term loans utilize a standard amortizing structure where you make equal monthly payments consisting of both principal and interest. In the beginning, the interest portion dominates your payment because it is calculated on the high initial principal balance. Over time, as you pay down the principal, the interest expense decreases and principal repayment accelerates.
To see a complete monthly breakdown of your payments, see our amortization calculator or check our general loan calculator.
Lenders evaluate your company's creditworthiness using the Debt Service Coverage Ratio (DSCR). This ratio compares your company's Net Operating Income (NOI) to its total annual debt payments (principal and interest). A DSCR of 1.25 means the business earns 25% more than it needs to cover its debt, which is typically the minimum threshold required by commercial banks.
To compare this with consumer debt limits, check our debt to income calculator or check the loan repayment planner.
- SBA Loans: Government-backed loans offered through private lenders, featuring low interest rates and long repayment terms. - Equipment Financing: Loans specifically used to buy business equipment, where the equipment itself serves as collateral. - Lines of Credit: Flexible funding that allows you to borrow up to a certain limit and pay interest only on the amount you actually draw.

Commercial loans often carry upfront costs, such as origination fees, appraisal fees, and legal charges. These fees are typically calculated as a percentage of the loan amount and are either paid at closing or added to the loan balance. These fees increase the effective interest rate of the loan, known as the Annual Percentage Rate (APR).
Secured business loans require collateral—such as real estate, equipment, inventory, or accounts receivable—which the lender can seize and liquidate if you default on payments. Unsecured loans do not require physical collateral but carry higher interest rates to compensate the lender for the increased risk. Additionally, many commercial lenders require a personal guarantee, making you personally liable for the debt if the business fails.
In most cases, the interest paid on a commercial loan is a fully deductible business expense under IRS guidelines. This lowers your net borrowing cost because it reduces your company's taxable net income at the end of the fiscal year. However, there are limitations on interest deductions for larger corporations, so consulting a tax professional or CPA is always recommended.
