How to Use the Business Loan Calculator
Follow these steps to get your loan estimate in under 60 seconds:
- Enter the loan amount. Type the total amount you want to borrow. Business loans typically range from $5,000 to $5 million.
- Enter the annual interest rate. Not sure what rate to use? Check the rate table below this calculator. Most bank term loans run 6 to 12 percent. Online lenders charge 15 to 40 percent.
- Choose the loan term. Select years or months. A longer term lowers your monthly payment but raises your total interest paid.
- Add fees (optional). Enter any origination fee or other upfront costs. This gives you the real APR, not just the stated rate.
- Add your income data (optional). Fill in your monthly net income and existing debt to calculate your DSCR. Most lenders require a DSCR above 1.25.
- Click Calculate. Your monthly payment, total interest, real APR, and full amortization schedule appear instantly.
Pro tip: Run the calculator three times. Try a 3-year term, a 5-year term, and a 7-year term. Compare the monthly payment vs total interest for each. Pick the term that fits your cash flow without costing more than you need to pay.
Types of Business Loans
Not all business loans work the same way. The type of loan you choose changes your interest rate, repayment term, and monthly payment. Use the right loan type in the calculator to get the most accurate estimate.
1. SBA Loans
SBA loans come from the U.S. Small Business Administration. The government backs a portion of each loan, so lenders offer lower rates and longer terms than most bank loans. SBA 7(a) loans go up to $5 million with terms up to 10 years for working capital or 25 years for real estate. Interest rates typically run 10 to 13 percent. These loans take longer to approve, but they save serious money over time for qualified borrowers.
Calculator tip: Use a 10-year term and 11% interest rate as a baseline SBA estimate.
2. Term Loans
A term loan gives you a lump sum upfront. You repay it in fixed monthly payments over a set period, usually 1 to 10 years. Banks and credit unions offer the lowest rates, typically 6 to 12 percent, but they require strong credit and at least 2 years in business. Online lenders approve faster but charge higher rates. Read our guide on how to get a startup business loan if you are just starting out.
3. Business Line of Credit
A line of credit works like a credit card. You draw funds when you need them and only pay interest on what you use. Credit limits range from $10,000 to $500,000. Interest rates run 8 to 24 percent depending on your credit profile. Use this for short-term cash flow gaps, not large capital investments.
Calculator tip: To estimate line of credit costs, enter the amount you plan to draw, a 12-month term, and your expected rate.
4. Equipment Financing
Equipment loans let you buy machinery, vehicles, or technology without draining cash reserves. The equipment itself serves as collateral, which keeps rates lower than unsecured loans. Terms match the useful life of the equipment, usually 3 to 7 years. Interest rates average 6 to 9 percent. You own the equipment outright once you finish repaying.
5. Invoice Factoring
Invoice factoring turns unpaid customer invoices into immediate cash. A factoring company buys your invoices at a discount, typically 70 to 90 percent of face value, and collects from your customers directly. This is not a traditional loan, so the calculator does not apply. But it is worth knowing as an alternative if you have strong receivables and a cash flow gap.

What Is DSCR and Why Does It Matter?
DSCR stands for Debt Service Coverage Ratio. Lenders use it to measure whether your business earns enough money to cover its loan payments. It is one of the first numbers a bank checks when you apply.
The formula is simple: Divide your monthly net income by your total monthly debt payments (including the new loan). A DSCR of 1.0 means your income exactly covers your debt. Most lenders require 1.25 or higher. That means for every $1.25 your business earns, $1.00 goes to debt.
| DSCR Score | What It Means | Loan Approval Chance |
| Below 1.00 | Business loses money after debt payments | Very unlikely |
| 1.00 – 1.24 | Income barely covers debt | Difficult — most banks decline |
| 1.25 – 1.49 | Comfortable buffer | Good — most lenders approve |
| 1.50 and above | Strong cash flow relative to debt | Excellent — best rates available |
Our calculator shows your DSCR automatically when you enter your monthly net income and existing debt. If your score falls below 1.25, try these steps before you apply:
- Pay down existing debt before adding a new loan.
- Extend the loan term to reduce the monthly payment.
- Borrow a smaller amount.
- Increase revenue for 3 to 6 months and then apply.

How to Lower Your Monthly Business Loan Payment
A high monthly payment can choke your cash flow. Before you accept a loan offer, try these five strategies to reduce what you pay each month:
1. Extend the loan term
A 5-year loan costs more in total interest than a 3-year loan, but the monthly payment is lower. Use the calculator to test different terms and find the sweet spot between monthly affordability and total cost.
2. Improve your credit score first
A credit score above 720 unlocks the lowest rates most lenders offer. Even a 1 to 2 percent rate drop saves thousands over a 5-year term. Check your score before you apply and spend 3 to 6 months improving it if needed.
3. Put up collateral
Secured loans carry lower interest rates because the lender takes less risk. Real estate, equipment, or inventory can all work as collateral. If you own business assets, offer them upfront to negotiate a better rate.
4. Shop at least three lenders
Rates vary widely between banks, credit unions, and online lenders. Get quotes from at least three sources and compare the APR, not just the interest rate. The APR includes fees, which our calculator already accounts for. The SBA lender match tool is a free way to find SBA-approved lenders near you.
5. Make a larger down payment
Borrowing less reduces both your monthly payment and total interest. If you have cash reserves, consider using them to reduce the loan principal. Run the smaller loan amount through the calculator to see how much it saves.
