What is a Business Loan Calculator?
A Business Loan Calculator is a free financial tool designed specifically for business owners and entrepreneurs to calculate monthly loan payments, total interest costs, and debt service coverage ratio (DSCR) for commercial financing. It helps you evaluate loan affordability, plan cash flow, and make informed borrowing decisions for business growth and operations.
This calculator is essential for evaluating:
- SBA Loans - Calculate payments for SBA 7(a), 504, and microloans with competitive government-backed rates
- Term Loans - Evaluate traditional bank loans and online lender financing for business expansion
- Equipment Financing - Determine costs for purchasing machinery, vehicles, or technology equipment
- Working Capital Loans - Plan for short-term financing to cover operational expenses and cash flow gaps
- Commercial Real Estate - Calculate payments for business property purchases or refinancing
For general loan payment calculations across different purposes, explore our Loan Calculator to understand monthly payments and total costs for any type of loan with instant results.
To calculate payments for individual financing needs, use our Personal Loan Calculator to compare different loan amounts and terms for personal borrowing decisions.
For planning how to pay off existing business debt efficiently, try our Repayment Calculator to create strategic payoff plans and save on interest costs over time.
To see detailed payment breakdowns over the life of your business loan, check our Amortization Calculator to visualize principal and interest allocation throughout the loan term.
How Business Loan Calculator Works
The calculator uses the standard amortization formula to calculate monthly business loan payments:
Where:
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of monthly payments (years × 12)
The calculator then computes business-specific metrics:
- Total Interest = (Monthly Payment × Number of Payments) - Principal
- Total Payment = Principal + Total Interest
- Annual Debt Service = Monthly Payment × 12
- DSCR = Net Operating Income ÷ Annual Debt Service
- Payment/Revenue Ratio = (Monthly Payment ÷ Monthly Revenue) × 100
The Debt Service Coverage Ratio (DSCR) is crucial for lenders - it shows whether your business generates enough cash flow to comfortably cover loan payments.
Key Concepts Explained
The ratio of net operating income to total debt service. Lenders typically require DSCR of 1.25 or higher, meaning your business generates 25% more cash than needed to cover loan payments.
Government-guaranteed loans through the Small Business Administration offering favorable terms. SBA 7(a) loans go up to $5 million with terms up to 25 years, while 504 loans finance fixed assets like real estate and equipment.
The difference between current assets and liabilities, representing funds available for daily operations. Working capital loans help bridge cash flow gaps and fund operational expenses.
Loans specifically for purchasing business equipment, where the equipment itself serves as collateral. Often offers lower rates than unsecured business loans due to reduced lender risk.
A lump-sum loan repaid over a fixed period with regular payments. Common for business expansion, large purchases, or refinancing. Terms typically range from 1-10 years depending on purpose.
Financing provided to businesses rather than individuals. Includes term loans, lines of credit, commercial real estate loans, and specialized industry financing with business-focused underwriting.

Frequently Asked Questions
What is a business loan calculator?
A business loan calculator is a free financial tool that helps business owners calculate monthly loan payments, total interest costs, and debt service coverage ratio (DSCR) for commercial loans. It enables you to evaluate loan affordability, plan cash flow, and compare different financing options for business growth and operations.
How do I calculate my business loan payment?
Business loan payments are calculated using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (years × 12). This formula applies to SBA loans, term loans, and most commercial financing.
What is a good debt service coverage ratio (DSCR)?
A good DSCR for business loans is 1.25 or higher. This means your business generates 25% more cash flow than needed to cover loan payments. Most lenders require a minimum DSCR of 1.25 for approval, with 1.5 or above considered excellent. A DSCR below 1.0 indicates insufficient cash flow to cover debt obligations.
What types of business loans can this calculator evaluate?
This calculator works for various business loans including SBA 7(a) loans, SBA 504 loans, term loans, equipment financing, commercial real estate loans, working capital loans, business lines of credit (when drawn), and merchant cash advances. It calculates payments for any fixed-rate loan with regular amortization.
How much can my business afford to borrow?
Your business can typically afford to borrow an amount where monthly payments don't exceed 25-30% of monthly revenue or net operating income. Use the DSCR calculation to ensure payments leave sufficient cash flow for operations. Most lenders want to see DSCR of 1.25+, meaning loan payments should be no more than 80% of available cash flow.
What interest rates do business loans typically have?
Business loan interest rates vary widely: SBA loans typically range from 5-11%, traditional bank term loans from 6-13%, online lenders from 8-25%, and equipment financing from 5-20%. Rates depend on credit score, business history, revenue, industry, loan amount, and collateral. Strong businesses with good credit get the lowest rates.
