What is a Business Loan Calculator?

A business loan calculator estimates your monthly payment, total interest, and amortization schedule for a business term loan, with the option to include a balloon payment — a large lump sum due at the end of the loan term, after a series of smaller regular payments. This structure is common for some business and commercial loans, where the smaller monthly payments are based on a longer amortization period than the actual loan term.

How to Use This Business Loan Calculator

  1. Enter the loan amount you're borrowing for your business.
  2. Enter the interest rate — the default is an example only, so enter the actual rate quoted by your lender, as business loan rates vary widely by lender, loan type, and your business's creditworthiness.
  3. Enter the loan term in years.
  4. If your loan includes a balloon payment, enter it as a percentage of the loan amount — this lowers your monthly payment but leaves a lump sum due at the end of the term.
  5. Optionally add an extra monthly payment and a start date, then review your monthly payment, balloon amount (if any), and full amortization schedule.

How is a Business Loan Payment Calculated?

When a balloon payment is included, the monthly payment is calculated so that the present value of all the regular payments plus the present value of the balloon payment equals the loan amount — effectively amortizing only the portion of the loan that isn't covered by the balloon.

Formula: Monthly Payment = [(P − Balloon ÷ (1+r)n) × r] / [1 − (1+r)−n], where P is the loan amount, r is the monthly interest rate, n is the number of months, and Balloon is the lump-sum amount due at the end of the term. With no balloon payment, this simplifies to the standard amortization formula.

Example: For a $100,000 business loan at a 9% interest rate (example rate — enter your actual rate) over 7 years with no balloon payment, the monthly payment would be roughly $1,613, with total interest of about $35,500 over the full term. Adding a balloon payment would lower the monthly payment but leave a lump sum due at the end. (Note: all figures in this example are for illustration purposes only and do not represent your actual loan terms.)

Business Loans in the US

Business loans in the US come in many forms — traditional bank term loans, SBA (Small Business Administration) loans with government-backed guarantees, equipment financing, lines of credit, and commercial real estate loans, each with different typical rates, terms, and qualification requirements. Rates as of Q2 2025 (example) varied significantly by loan type and lender, often higher than residential mortgage rates and dependent on the business's revenue, time in operation, and the owner's personal credit. Balloon payment structures are sometimes used in commercial lending, where the borrower makes payments based on a longer amortization schedule (lowering monthly cash flow needs) but must pay off or refinance the remaining balance at the end of a shorter actual term (example structure — verify your specific loan's terms).

Tips for Using This Business Loan Calculator

  • If your loan has a balloon payment, plan ahead for how you'll handle it — whether through refinancing, a planned sale of the financed asset, or accumulated cash reserves — since it's a substantial lump sum due at the end of the term.
  • Compare offers from multiple lenders, including banks, credit unions, and SBA-backed loan programs, as rates and terms can vary significantly for similar businesses.
  • Use the extra monthly payment field to see how paying down principal faster could reduce or eliminate a balloon payment, or shorten your overall term.
  • Remember this calculator estimates interest costs only — origination fees, closing costs, and other loan fees common in business lending aren't included.

Frequently Asked Questions

What is a balloon payment on a business loan?

A balloon payment is a large lump-sum payment due at the end of a loan term, after a series of smaller regular payments calculated using a longer amortization period. It lowers monthly payments but requires the borrower to pay off or refinance the remaining balance when due.

Is the 9% interest rate accurate for my business loan?

No — the default is an example only. Business loan rates vary significantly based on the loan type (term loan, SBA loan, equipment financing, etc.), the lender, and your business's creditworthiness and time in operation. Enter the actual rate quoted to you.

What is an SBA loan?

An SBA loan is a loan partially guaranteed by the US Small Business Administration, issued through participating lenders. The government guarantee can allow for more favorable terms than conventional business loans, though the application process can be more involved.

What happens if I can't pay off the balloon payment when it's due?

If you can't pay the balloon payment in cash, common options include refinancing the remaining balance into a new loan, selling the financed asset, or negotiating with your lender — but these options aren't guaranteed, so planning ahead for a balloon payment is important.

Does this calculator include fees like origination or closing costs?

No. This calculator estimates principal and interest payments only. Business loans often involve additional fees — such as origination fees, closing costs, or annual fees — that would add to your total cost and aren't included here.

How does an extra monthly payment affect a loan with a balloon payment?

Extra payments reduce your principal balance faster, which can reduce the size of the balloon payment due at the end of the term (or eliminate it entirely if the loan is paid off before the balloon date), in addition to reducing total interest paid.
