    Step-by-step guide

    How to use this business loan calculator.

    Our business loan calculator is designed to give you a clear, instant picture of what your financing will actually cost. Whether you're exploring a small business loan, comparing short-term loan options, or planning a long-term investment — this tool breaks everything down in seconds.

    Start with the Loan Amount slider. Drag it anywhere from $5,000 to $500,000 to set the total amount you want to borrow. This represents the principal — the base amount before any interest or fees. If you're unsure how much you need, start with your estimated project cost or the cash gap you're looking to fill.

    Next, set your Loan Term. This slider ranges from 3 to 60 months. Shorter terms mean higher monthly payments but dramatically less total interest paid. Longer terms lower your monthly obligation but increase the overall cost. For working capital loans, terms of 6–24 months are most common. For SBA loans, you may need even longer terms — contact our advisors for custom quotes.

    Select your Credit Profile. Choose from Excellent, Good, Fair, or Poor. Each selection maps to an estimated APR range that real lenders offer for that credit tier. This directly impacts your calculated monthly payment and total interest. If your credit is below 600, don't worry — loans for bad credit are still available with competitive terms.

    Optionally, add Extra Monthly Payments. This powerful feature shows you exactly how much interest you'll save — and how many months you'll shave off — by paying more than the minimum each month. The amortization schedule graph updates in real time, showing the principal vs. interest split across every payment period. Toggle between the amortization view and payment breakdown to fully understand your loan's cost structure.

    Five ways to lower your loan cost.

    Credit

    Strengthen Your Credit Profile

    Even a 50-point improvement in your credit score can drop your APR by 3–5%. Pay down revolving balances, correct reporting errors, and maintain on-time payments for 90 days before applying.

    Strategy

    Choose a Shorter Repayment Term

    A 12-month term on a $100K loan at 15% APR saves over $8,000 in interest compared to a 36-month term. If your cash flow supports higher monthly payments, shorter terms dramatically cut your total cost.

    Make Extra Monthly Payments

    Adding even $150/month to a $200K loan at 12% APR can shorten your payoff by 6+ months and save over $3,000 in total interest. Use the extra payment slider above to see your exact savings.

    Collateral

    Consider Secured Financing

    Offering collateral — equipment, real estate, or inventory — can unlock APRs 5–10% lower than unsecured options. If you have assets, secured business loans deliver significantly better terms.
