Small Business Loans: Rates, Terms & Free Calculator
Key Takeaways
- Small business loan rates range from 6% (bank loans) to 30%+ (online lenders) — your credit score and business history determine where you fall
- Lenders look at your debt-to-income (DTI) ratio — keep it below 35% for the best approval odds and rates
- SBA loans offer the best balance of rate and accessibility, with government backing that reduces lender risk
- Longer loan terms mean lower monthly payments but higher total interest — the right term balances cash flow with total cost
- Prepayment penalties of 1-3% are common on business loans — always check before paying early
Securing the right financing is one of the most critical decisions a small business owner faces. Whether you're launching a startup, expanding operations, purchasing equipment, or managing cash flow gaps, a small business loan can provide the capital you need to grow. However, the world of business lending is complex — rates, terms, qualification requirements, and repayment structures vary dramatically between lenders, and choosing the wrong loan can cost tens of thousands of dollars in unnecessary interest.
Small business loans come in several forms. Term loans provide a lump sum upfront that you repay with interest over a fixed period, typically 1 to 10 years. SBA loans are partially guaranteed by the Small Business Administration, which reduces risk for lenders and allows them to offer competitive rates (typically 7-13%) even to businesses that might not qualify for traditional bank loans. Business lines of credit offer flexible borrowing up to a limit — you draw what you need and pay interest only on what you use. Equipment financing uses the equipment itself as collateral, and invoice factoring lets you sell unpaid invoices for immediate cash.
The interest rate you're offered depends on several factors: your personal and business credit scores, time in business (lenders prefer 2+ years), annual revenue, existing debt, and the loan type. Traditional bank loans offer the lowest rates (5-9%) but have strict qualification requirements. Online lenders provide fast funding and easier qualification but charge significantly higher rates (15-40%). SBA loans sit in the middle, offering competitive rates with more paperwork and longer processing times. Understanding these tradeoffs is essential for choosing the right financing for your situation.
Before applying, calculate your debt-to-income ratio (monthly debt payments divided by monthly revenue). Most lenders want to see a DTI below 35-50%. Also consider the total cost of the loan, not just the monthly payment. A 5-year loan at 8.5% on $100,000 results in about $22,800 in total interest — meaning you repay nearly $123,000 in total. The amortization schedule below breaks this down year by year, showing how much of each payment goes to principal versus interest.

What This Calculator Shows
This business loan calculator shows your monthly EMI payment, total interest over the loan term, total repayment amount, and the number of payments. If you enter your monthly revenue, it also calculates your debt-to-income (DTI) ratio — a key metric lenders use to evaluate your loan application. The yearly amortization schedule shows how each year's payments break down between principal and interest.
How to Use the Small Business Loan Calculator
Using this business loan calculator is straightforward. Start by entering the loan amount you plan to borrow for your business. Then input the annual interest rate your lender has quoted. Business loan rates typically range from 6% to 30% depending on your creditworthiness, business history, and loan type.
Choose your loan term in years or months — most small business loans range from 1 to 10 years. You can switch between years and months using the dropdown. If you enter your monthly revenue, the calculator will also show your debt-to-income (DTI) ratio, which lenders use to assess your ability to repay.
Click "Calculate" and you'll see your monthly EMI payment, total interest, and total repayment amount. The yearly amortization schedule breaks down how much of each year's payments go toward principal versus interest.
Business Loan EMI Formula
The monthly payment is calculated using the standard amortization formula:
Where: EMI = monthly payment, P = loan principal, r = monthly interest rate (annual rate / 12), and n = total number of monthly payments.
The debt-to-income ratio is calculated as: DTI = (Monthly Payment / Monthly Revenue) × 100.
Next Steps
- Check your credit score before applying — both personal and business scores affect your rate and approval odds
- Compare at least 3-5 lenders including banks, credit unions, SBA lenders, and online platforms to find the best terms
- Gather your documents — tax returns, financial statements, business plan, and bank statements are typically required
- Consider the total cost, not just the monthly payment — a longer term lowers payments but increases total interest paid
- Negotiate terms — rates and fees are often negotiable, especially with banks and credit unions where you have an existing relationship
