What Is a Business Loan?

A business loan is a form of commercial financing where a lender provides capital to a business in exchange for interest payments over a set period. Understanding the true cost of business capital — including all fees and compounding effects — is essential for making informed financing decisions and maintaining healthy cash flow.

Types of Business Financing

Not all business capital is created equal. The source of your funds dictates the flexibility and total cost:

  • Term Loans: A lump sum of capital repaid over a set period (1-10 years). Best for specific growth projects like equipment purchases or expansion.
  • SBA Loans (7(a) & 504): Government-backed loans for small businesses with favorable terms. Lower rates and longer terms, but a longer application process and strict "Guarantee Fees."
  • Line of Credit (LOC): Flexible funding that works like a credit card for your business. You only pay interest on the amount you actually draw.
  • Merchant Cash Advance (MCA): An advance against future sales. Caution: These often have extremely high effective APRs (40-100%+).

The Hidden Cost: Origination & Guarantee Fees

In business lending, the interest rate is rarely the only cost. Lenders typically charge additional fees that significantly increase the true cost of borrowing:

  • Origination Fees: 1-5% of the loan amount, usually deducted from the proceeds at closing.
  • SBA Guarantee Fees: Fees paid to the government to secure the loan guarantee.
  • Servicing Fees: Monthly or annual fees to maintain the loan account.

Our calculator factors these into the Real APR to give you the honest price of the capital.

Loan TypeTypical APRTerm Length
Bank Term Loan6% – 12%1–10 years
SBA 7(a)Prime + 2.25% – 4.75%7–25 years
Online Lender15% – 35%3 months – 5 years
Merchant Cash Advance40% – 100%+3–18 months

Debt Service Coverage Ratio (DSCR)

Lenders calculate your DSCR to determine whether your business generates enough cash flow to service the new debt. The formula is: DSCR = Net Operating Income ÷ Total Debt Service. Most banks require a minimum DSCR of 1.25x, meaning for every $1 of debt payment, your business should generate at least $1.25 in free cash flow.

Preparing for the Application

Banks evaluate the Five C's of Credit: Character, Capacity, Capital, Collateral, and Conditions. To secure the best rates, prepare:

  • Balance Sheets & P&L Statements: For the last 3 years.
  • Business Tax Returns: Last 3 years.
  • Personal Tax Returns: For all owners with >20% equity.
  • Debt Schedule: A list of all current business liabilities.

Floating vs. Fixed Rates

Many business loans (especially SBA 7(a)) use floating rates tied to the WSJ Prime Rate. If the Fed raises interest rates, your payment increases automatically. Use this calculator to stress-test your budget by modeling rate increases of 2-3%.

Frequently Asked Questions

What is the typical interest rate for a business loan?▼
Rates vary by type: Bank term loans (6-12% APR), SBA 7(a) (Prime + 2.25-4.75%), online lenders (15-35% APR). Merchant cash advances can exceed 40% effective APR.
What is the difference between APR and interest rate?▼
Interest rate is the base cost of borrowing. APR includes all fees (origination, guarantee, servicing) to show the true annualized cost of the loan.
What is DSCR and why does it matter?▼
Debt Service Coverage Ratio (Net Operating Income ÷ Total Debt Service) shows lenders if your business can afford the loan. Most require a minimum of 1.25x.
How does compounding frequency affect my loan?▼
More frequent compounding (daily vs. monthly) increases the total interest paid over the life of the loan. The difference becomes more significant with higher interest rates and longer terms.

How the calculation works

A business term loan payment depends on the amount financed, the annual rate, and the number of months.

M = P × [ r(1+r)^n ] / [ (1+r)^n − 1 ] r = annual rate ÷ 12 n = years × 12

M is principal and interest only. Taxes, fees, and insurance are added after this payment.

Worked example: $100,000 at 9% for 7 years

  1. Loan amount P = $100,000.00.
  2. Monthly rate r = 9 ÷ 12 ÷ 100 = 0.007500.
  3. Number of payments n = 7 × 12 = 84.
  4. Monthly principal and interest = $1,608.91.
  5. Interest over the full term = $35,148.26.

Frequently asked questions

What is the monthly payment on $100,000 at 9% for 7 years?▼
About $1,608.91. That payment covers principal and interest. Over 7 years the interest is about $35,148.
What does the payment formula use?▼
It uses the loan amount, the monthly interest rate, and the number of monthly payments. The payment stays level, while the share that goes to interest falls over time.
How much interest does a shorter term save at 9%?▼
A 4-year term on the same $100,000 loan costs $2,488.50 a month and about $19,448 in interest, compared with $35,148 on the 7-year term.
