Bookkeeping for a Business Line of Credit: Draws, Interest, and How It Differs From a Term Loan

Revolving, not amortizing

A term loan and a line of credit are both borrowing, but they behave differently enough that recording one like the other will quietly break your books. A term loan arrives as a single lump sum and leaves on a fixed amortization schedule — every payment is a set blend of principal and interest, calculated in advance for the life of the loan. A line of credit is revolving: the lender approves a credit limit, and you draw against it whenever you need cash, repay when you can, and draw again later. In mechanics it behaves far more like a business credit card than like a term loan, and that difference changes how nearly every transaction gets recorded.

Get the model right and a line of credit is one of the cleaner things to keep on the books. Get it wrong — usually by treating a draw as income or lumping interest in with principal — and the revolving balance becomes a running distortion of both your profit and what you actually owe. (This is general educational information about accounting concepts, not accounting advice for your specific situation.)

A draw is borrowing, not income

When you draw on the line, cash lands in your account, and it is tempting to categorize an incoming deposit as revenue. It is not. Just like the funding of a term loan, a draw is money you have to pay back, so in double-entry terms it increases an asset and increases a liability by the same amount:

• Debit Cash — your bank balance goes up.
• Credit Line of Credit Payable — a liability goes up by the amount drawn.

Nothing touches your profit and loss statement, because borrowing does not make you richer — it swaps a future obligation for cash today. Draw ten thousand dollars and your bank balance rises by ten thousand while a line-of-credit liability of ten thousand appears on the balance sheet. Your profit for the month is unchanged. If you draw several times, each draw adds to the same liability account, so the balance always shows the total you currently owe on the line.

Repaying principal reduces the liability

When you pay money back on the line, the principal portion simply reverses the draw — it reduces the liability you already recorded. The entry is the mirror image of a draw:

• Debit Line of Credit Payable — the liability goes down.
• Credit Cash — money leaves your bank account.

Principal repayment is not an expense. You are returning borrowed money, not consuming a cost, so it never touches the P&L. This is the same principle that governs the principal half of a term-loan payment — but here is where the two products diverge sharply.

Interest is separate — and this is the big difference from a term loan

On a term loan you record each fixed payment by splitting it into principal and interest according to the amortization schedule. A line of credit has no such schedule. Instead:

• Interest is charged only on the balance you have actually drawn, not on your full credit limit. If your limit is fifty thousand but you have only drawn ten thousand, interest accrues on the ten thousand.
• Interest accrues over time on the outstanding balance — typically day by day — and the lender bills it periodically, usually monthly.
• Principal repayment is at your discretion. Many lines are interest-only in the sense that you must pay the billed interest each period, but you choose how much principal to pay down and when, up to any minimum.

So instead of splitting one blended payment, you record two independent things. When the lender charges interest, you book it as interest expense — debit Interest Expense, credit either Cash (if paid immediately) or a small interest-payable liability until you pay it. When you pay down principal, you record that separately against the liability as shown above. The interest is the only part that ever hits your profit; the principal movements live entirely on the balance sheet. Because interest builds up between billing dates, at a month-end close you may accrue the interest that has accumulated on the drawn balance but has not yet been billed, so the expense lands in the month you actually used the money.

Treat the statement like a credit-card reconciliation

Because a line of credit revolves, the cleanest way to keep it honest is to reconcile it each period against the lender's statement, exactly the way you would reconcile a credit-card account. The statement shows your opening balance, every draw, every payment, the interest charged, and the closing balance. Your Line of Credit Payable account should tie to that closing balance, and the interest on the statement should match the interest expense you booked. Any gap is a draw, a payment, or an interest charge you have not recorded yet — caught while it is still easy to fix.

Fees, and where the line sits on your balance sheet

Lines of credit often carry fees that are not interest: an origination or annual fee to keep the line open, and sometimes an unused-line fee charged on the portion of your limit you have not drawn. These are financing costs — record them as an expense (a bank or interest-and-financing expense), not as principal against the liability.

One more distinction worth getting right is classification. A revolving line of credit is generally a current liability, because it is short-term and repayable on demand, whereas a term loan is usually split into a current portion (the next year of principal) and a long-term portion. And note what does not appear on your books at all: your undrawn availability. If you have a fifty-thousand-dollar limit and have drawn ten thousand, only the ten thousand you owe is a liability — the forty thousand you could borrow is not recorded, because you do not owe it until you draw it. That available credit is a useful cushion in your cash-flow forecast, but it is not an asset and not a liability until it is used.

Why the distinction matters

Recording a line of credit correctly keeps three numbers honest at once. Your profit stays right because only interest and fees — never draws or principal repayments — flow through the P&L. Your balance sheet stays right because the Line of Credit Payable balance tracks exactly what you owe, rising with each draw and falling with each principal payment. And your cash-flow picture stays right because you can see the line for what it is: a flexible source of cash that has to be repaid, with a real interest cost on whatever you are carrying.

The one-sentence version: a draw is a liability, not income; a principal repayment reduces that liability, not your profit; and interest — charged only on what you have actually drawn — is the sole part that is ever an expense. Keep those three straight and a revolving line stays as clean on the books as it is useful in the bank.

Hosting Books lets you record a line of credit as its own liability, book draws and principal repayments against it, and post interest separately as an expense, so the balance revolves correctly on your balance sheet while only the interest and fees reach your profit.
