What it means
Available credit is the amount still open to draw on a credit line, overdraft or business card, and it equals the limit minus the amount used. As a business draws funds, available credit falls, and repayments increase it again.
It can add to liquidity, and suppliers give trade credit limits too, so the idea applies to purchasing as well as borrowing. Ask which limit is being measured.
A card's displayed available amount, an overdraft's unused capacity and a supplier's remaining order allowance may use different rules, and pending card charges, accrued interest or uncleared repayments can make a screen balance differ from the amount actually drawable. A payment may not restore card capacity immediately and a supplier may count uninvoiced shipments, so leave room for delayed posting and exchange-rate movements, and confirm the current terms before planning a payment, because a lender may also reduce or suspend an uncommitted facility.
In the simple example, a $1 million credit line with $650,000 drawn leaves $350,000 of nominal capacity. It does not follow that $350,000 can safely be used for stock, because the business still owes interest and principal and needs enough cash for payroll and tax.
A line with covenants or a borrowing-base test may also make the permitted draw lower than the arithmetic difference. Available credit is a financing source, not earnings and not free cash.
Drawing the line adds both cash and debt, and spending it removes cash but leaves the debt to repay, so a cash forecast should show draw dates, interest, fees, repayment dates and the sales or receipts expected to restore the balance. If the line is routinely full, it may be financing permanent working-capital needs with a short-term product, and repaying one facility with another merely shifts the debt.
High utilisation can be an early warning, even before a default, and using most of a credit line for long periods can worry lenders and lower credit scores. US consumer credit scoring models may consider the percentage used on a card, but that rule should not be carried over unchanged to every business facility, since lenders also look at repayment conduct, cash flow and covenants.
Do not add facilities blindly either, because drawing one loan may breach another covenant and supplier credit cannot pay wages, so record permitted uses, cost, expiry and shared collateral separately. For owners, the direct operating concern is whether the business has room for a bad month or a delayed customer payment, which is why available credit belongs beside cash balances in any view of true short-term headroom.
Use a weekly cash table alongside each facility's drawn and usable amounts, cost and renewal date, reconcile it to statements, and negotiate seasonal needs before the peak rather than after a declined draw. Collection and stock planning create more lasting room than reshuffling debt, and the facility contract governs whether unused capacity remains open.
In practice
Real-world examples.
Example
A business has an approved $1 million line and has drawn $650,000. Its nominal available credit is $350,000 before facility conditions and pending charges.
Example
A supplier extends $80,000 trade credit. After $55,000 of accepted orders, the remaining purchasing room is $25,000, not cash the business can use for wages.
Example
A card payment posts after two days. The owner waits for the available balance to update before placing an essential order instead of assuming the limit reset instantly.
Formula
Calculation
Available credit = Credit limit minus Amount used.
Worked example: a credit line of $1,000,000 has $650,000 drawn, so available credit is $1,000,000 - $650,000 = $350,000. Utilisation is $650,000 / $1,000,000 = 65%. If a covenant caps total borrowing at $800,000, the permitted further draw is $800,000 - $650,000 = $150,000, well below the $350,000 nominal figure. If $20,000 of card charges are pending, the usable room falls further to $130,000.Case study
Seen in the real world.
This illustrative and entirely fictional example follows Sandstone Trading, an invented importer that looked only at its bank balance. During peak season, Sandstone had $400,000 at the bank but large supplier payments due before customers would pay. Its $1 million facility was already mostly drawn and some charges had not yet posted.
The finance manager built a weekly cash forecast showing the usable facility headroom separately from cash. In this fictional scenario, the group negotiated a seasonal increase before its next buying cycle and set a repayment target after customer collections. It did not treat the higher limit as profit or a reason to buy stock without orders.
Watch out
Common mistakes.
- Treating available credit as spare cash to spend, when it is borrowing that must be repaid with interest and may be withdrawn or restricted by the lender.
- Running credit lines near their limit for long periods, which leaves no room for a delayed customer payment and can worry lenders.
- Not tracking supplier credit limits, so orders are placed that the supplier then holds or refuses to ship.
Questions
People also ask.
What is available credit?
It is the unused part of a credit limit at a point in time. The amount actually drawable can differ because of pending items, covenants and lender rules.
How is it calculated?
Subtract the used balance from the approved limit for a simple estimate. Confirm the provider's current available amount and any restrictions before relying on the figure.
Why does it matter?
It shows short-term borrowing room when cash receipts are delayed. It also signals when a company is approaching its limit and needs a plan for repayments or lower spending.
