If an overdraft has no repayment schedule, how does it ever get paid back? Through deposits, interest debits and the review the bank runs on the facility. Here is how each one works, and what the balance should be doing across a trading year.
Quick Answer
A business overdraft typically has no fixed instalment: every deposit reduces the drawn balance, interest is charged on what you actually use, and the bank expects the balance to move rather than sit near the limit. The business overdraft guide covers how the facility works day to day; this insight covers how the money comes back, and where a business line of credit with a set minimum repayment works differently.
Also called: overdraft repayment terms, paying back an overdraft, overdraft clean down. "Clean down" or "clean out" is a lender expectation that the balance returns to zero or into credit for a period, not a separate product.
How do business overdraft repayments work?
Business overdraft repayments happen automatically whenever money lands in the account: every deposit reduces the drawn balance, and the part of the limit you free up can be drawn again straight away. There is typically no fixed instalment and no separate loan account to pay into. The overdraft lives inside your business transaction account, so customer payments, card settlements and transfers in all count as repayments the moment they clear.
That is the main difference from a term loan. A loan falls by a set amount each month. An overdraft falls and rises with your cashflow: wages, suppliers and tax payments push the balance down toward the credit limit, and receipts pull it back. If you have not used an overdraft before, the business overdraft guide covers drawing, limits and day-to-day use. This page stays with the other half: how the money comes back.
Because repayment is automatic, the real question is not "when is my repayment due" but "is enough coming in, often enough, to bring the balance back". That is what the bank is checking every time it looks at the account.
Is there a minimum repayment on a business overdraft?
A business overdraft at a major bank usually has no minimum repayment beyond the interest, which is debited to the account and simply added to the drawn balance. As long as you stay inside the limit and the bank is comfortable at review, nothing else is formally due.
Non-bank revolving facilities can be different. Some non-bank lenders set a minimum monthly repayment, or an amortising repayment that brings part of the balance down each month, and the amount varies by lender. These products are often sold as a business line of credit rather than an overdraft, and they usually sit in a separate account rather than inside your transaction account. The overdraft versus line of credit guide sets out how the two differ.
No minimum does not mean no expectation. The bank still expects the balance to come down regularly, and it reads the account at review to see whether it did.
How is overdraft interest charged and debited?
Overdraft interest is charged on the drawn balance only, typically calculated daily and debited monthly. Each day the bank calculates interest on what you owe that day, then debits the month's total to the account, where it becomes part of the balance.
That last step matters for repayments. If the account sits near the limit, the monthly interest debit lands on top of a balance that never falls, and interest is then charged on that interest. A balance that swings back toward zero each month keeps the interest bill small and stops this from building.
Two related costs have their own pages. Line fees and fees on an unused limit, and how the rate is set and changed, are covered in the overdraft rates and fees guide. What happens when the balance goes past the limit, and whether you pay interest on the whole limit, is covered in going over your business overdraft limit.
What should your overdraft balance do over a year?
An overdraft balance should rise when you spend ahead of income and fall back when customers pay, spending some time near zero or in credit: the balance should swing, not sit. A balance that stays pinned near the limit all year tells the bank the facility is funding something permanent, not short gaps.
Most businesses have a pattern. A café stocks up before summer, a builder waits on progress claims, a wholesaler carries stock into the busy season. Each of those draws the overdraft down and should bring it back. The table shows the difference between a facility that does that and one that never clears, on a round example limit.
| Point in the year | Healthy pattern | Never-clears pattern | What the bank reads |
|---|---|---|---|
| First quarter, busy season build-up | Drawn to around $70,000 as stock and wages go out | Around $95,000, close to the limit | Drawing for trade is expected; the question is what happens next |
| Second quarter, customers pay | Back to around $20,000 | Still around $90,000 | Whether receipts bring the balance down when they land |
| Third quarter, quiet period | In credit for several weeks | Lowest point around $85,000 | The lowest balance shows how much is permanently drawn |
| Fourth quarter, next build-up | Around $40,000 drawn | Around $98,000, sometimes over | Headroom left, and any excess or dishonours |
| At review | Usually renewed on similar terms, varies by lender | Questions about the permanently drawn part, a reduction schedule or a term-out | Whether the facility is still doing a short-term job |
From the bank's side, where this commonly lands is the lowest point of the year. If the balance never drops below a certain level, that level is treated as long-term debt sitting in a short-term facility, and lenders call it the hardcore part of the overdraft. Fixing it usually means moving that amount into a loan with regular repayments, covered in turning a hardcore overdraft into a term loan. The bank statements are where all of this shows, and how a lender reads your overdraft statements walks through what they look for.
What does repayable on demand mean for a business overdraft?
Repayable on demand means the facility terms let the bank ask for the whole balance to be repaid, rather than waiting for a set end date. Most business overdraft terms carry some version of this wording, and it is the reason an overdraft has no repayment schedule: legally, the balance can be called.
Banks rarely use it out of the blue. Where it does come up, it is usually at an annual review, after a payment default, or when the business is clearly in trouble. Banks that subscribe to the Banking Code of Practice also accept limits on how they do it. At the time of writing, the Code's small business terms say:
- After a payment default, the bank gives at least 30 days' notice before demanding full repayment or enforcing, with shorter notice allowed where there is insolvency or a material and immediate risk.
- Where a facility is not repaid by regular repayments, such as an overdraft, the bank gives at least three months' notice that it will not extend it.

Those are the Code's own terms, and they apply only to subscribing banks, so check the current version and your own facility terms. Non-bank lenders that do not subscribe set their own notice terms; what to look for in the facility wording is covered in overdraft letter of offer clauses. If a bank has already asked for the balance back, the recalled facility guide covers what to do next.
Can the bank put your overdraft on a reduction schedule?
A bank can put an overdraft on a reduction schedule, usually at review, which steps the limit down by agreed amounts on agreed dates until it reaches a lower figure or closes; the terms differ between lenders. When that happens, the overdraft starts behaving like a loan with repayments, because the balance has to fall under each new limit as it arrives.
A softer version is a clean down condition. Instead of cutting the limit, the bank asks that the account return to zero or into credit for a set number of days in the year. On the renewals we see, these conditions tend to appear where the balance has sat high for a long stretch, and they are written into the renewed facility letter, so they are easy to miss until the date comes round.
Both are repayment mechanisms dressed as review conditions, and both can be planned for. Getting ready for the review itself is covered in the overdraft annual review plan, and what to do when the limit has already been cut is covered in the reduced overdraft limit guide.
How do you pay down a business overdraft faster?
You pay down a business overdraft faster by getting more money into the account sooner and keeping less of it sitting elsewhere. None of these steps needs the bank's permission:
- Sweep surplus cash. Money parked in a savings or tax account still costs you overdraft interest while the overdraft is drawn. Keep tax set aside, but move genuine surplus across.
- Time receipts and payments. Bill as soon as work is done, and line up supplier payments for after your main receipts land rather than before.
- Shorten debtor days. Tighter terms, deposits on larger jobs and prompt follow-up bring the balance down faster than any rate cut.
- Turn invoices into cash. Where customers pay slowly, invoice finance releases most of the invoice value early, and that money can clear the overdraft.
- Ask for a lower limit. Once the balance is down, a smaller limit can reduce line fees and removes the room to drift back up.
Should you close the overdraft once it is paid off?
Closing an overdraft once it is paid off makes sense when you no longer need the buffer, because it stops the fees and lets you ask the bank to release the security, unless that security also covers other debts with the bank. If the business still has seasonal gaps, keeping a smaller limit is usually cheaper than reapplying later. If the balance cannot be brought down from cashflow at all, refinancing the stuck part into a loan is usually the cleaner fix.
A business overdraft is repaid by your own trading. Every deposit reduces the drawn balance, interest is added monthly, and there is usually no fixed instalment. What the bank wants to see is a balance that rises and falls with the business and spends time near zero. When it does not, the bank has tools: review conditions, clean downs, reduction schedules and, in the end, the right to call the balance, limited for subscribing banks by the Banking Code.
Key takeaway: check your lowest overdraft balance across the last year before the bank does, and if it never falls, fix that part before your review.Frequently Asked Questions
Overdraft repayments work by deposit rather than by instalment: every payment into the business account reduces the drawn balance, and that part of the limit can be used again. Interest is charged on the drawn balance and debited to the account, typically monthly. The business overdraft guide covers how the facility works day to day.
No single business overdraft has the best repayment terms for everyone, because the right terms depend on how your cashflow moves. Compare whether there is a minimum repayment, whether clean down conditions apply, how often the facility is reviewed and what notice applies, all of which vary by lender. A business line of credit from a non-bank lender can suit a business that prefers a set monthly repayment.
Paying off an overdraft with a credit card is usually treated as a cash advance, which typically costs more than the overdraft and starts charging interest straight away. It moves the debt rather than reducing it. If the balance will not come down from trading, the overdraft rates and fees guide and a conversation about restructuring are better starting points.
A bank can usually ask you to repay an overdraft at any time under the facility terms, because most business overdrafts are written as repayable on demand. In reality banks tend to act at review or after a default, and subscribing banks follow the notice terms in the Banking Code of Practice. The recalled facility guide covers what to do if it happens.
An overdraft that never goes back into credit tells the bank part of the balance is permanent, which lenders call the hardcore part of the overdraft. At review the bank may ask for a clean down, set a reduction schedule or suggest moving that amount into a loan with regular repayments. Our insight on turning a hardcore overdraft into a term loan covers how that works.
