    How this calculator works

    1. 1

      Enter your approved credit limit and the amount you plan to draw right now.

    2. 2

      Add the APR and any per-draw fee your lender charges (typically 1.5–3% of the draw).

    3. 3

      Pick how many months you'll take to pay it back. We compute your monthly payment, total interest, and a fee-adjusted effective APR.

    Frequently asked questions

    Do I pay anything if I don't draw?

    Most business lines of credit have no monthly fee when drawn at zero, though some charge a small annual maintenance fee. Read the agreement carefully.

    How is a line of credit different from a credit card?

    Lines of credit usually have lower APRs, larger limits, and no rewards. They're better for predictable cash-flow gaps; credit cards are better for everyday expenses you can pay off monthly.

    What is a 'draw fee'?

    Some lenders charge a flat percentage every time you draw funds — often 1.5% to 3%. It's effectively pre-paid interest, so we factor it into your effective APR.
