What it means
When you sell goods or services on credit, you record the sale as revenue and the unpaid amount as an account receivable on your balance sheet. However, business reality means a small percentage of customers will inevitably default due to insolvency or disputes.
Rather than waiting until you write off the invoice completely, accounting rules require you to anticipate these losses. By creating a bad debt provision, you match the potential loss to the period in which the original sale occurred.
This practice follows the accrual principle, which states that expenses should be recognised in the same period as the related revenues. It prevents your company from overstating its profits and gives managers a realistic view of the cash they can actually expect to collect.
In practice, businesses calculate this provision using historical averages, industry benchmarks, or an ageing report that categorises unpaid invoices by how long they are overdue. As invoices age past ninety or one hundred and twenty days, the likelihood of collection drops sharply, and the provision percentage increases accordingly.
When a specific debt is finally confirmed as uncollectible, it is written off directly against this previously established provision, leaving your current operating results unaffected.
In practice
Real-world examples.
Example
A digital design agency with 50,000 pounds in unpaid client invoices estimates that 5 percent will not be paid. They record a bad debt provision of 2,500 pounds to reflect a realistic collection expectation.
Example
A wholesale bakery selling goods to local cafes holds 20,000 pounds in receivables. Following a local economic downturn, they increase their bad debt provision from 2 percent to 8 percent to cover potential defaults.
Example
A commercial cleaning firm with 100,000 pounds in outstanding corporate accounts reviews invoice ageing and sets aside 10,000 pounds for accounts more than 90 days overdue, ensuring accurate financial reporting.
Think of it
“Imagine you lend money to friends and keep a mental note that one or two of them might forget to pay you back. Instead of assuming you are fully rich, you mentally discount your total by a few pounds so you are never caught short.
Formula
Calculation
Estimated Bad Debt = Total Accounts Receivable x Estimated Percentage Uncollectible
Example: If your total accounts receivable equal 100,000 pounds and your historical data shows that 3 percent of invoices are never paid, your calculation is:
100,000 pounds x 0.03 = 3,000 pounds
You record a bad debt provision of 3,000 pounds, reducing the net value of your receivables on the balance sheet to 97,000 pounds.Case study
Seen in the real world.
BrightSpark Lighting, a mid-sized commercial supplier, finished the financial year with 500,000 pounds in outstanding accounts receivable. Historically, the company experienced a 2 percent default rate from retail clients who closed unexpectedly or disputed charges. The finance manager reviewed the ageing report and noted that economic pressures might push this default rate up to 4 percent for invoices over 90 days old.
To maintain compliance and provide a truthful picture to stakeholders, BrightSpark established a bad debt provision of 15,000 pounds, calculated by applying tiered percentages to different ageing categories of debt. This adjustment reduced net receivables on the balance sheet to 485,000 pounds and decreased net profit by the same 15,000 pounds for that accounting period.
Six months later, a specific client owing 4,000 pounds entered liquidation and could not pay. Because BrightSpark had already anticipated this type of loss through their provision, they simply wrote off the 4,000 pounds against the existing reserve. This meant their monthly operating profit for that month remained unaffected by the bankruptcy, proving the value of proactive financial planning.
Watch out
Common mistakes.
- Waiting until a customer explicitly declares bankruptcy before acknowledging any loss on an invoice.
- Using a static percentage year after year without reviewing actual historical collection rates.
- Forgetting to reduce the bad debt provision when old debts are successfully collected or written off.
Questions
People also ask.
Is a bad debt provision the same as writing off a debt?
No. A provision is an estimate of future losses based on probability. A write-off is the removal of a specific, confirmed uncollectible debt from your accounts.
Does creating a bad debt provision cost actual cash?
No, it is an accounting adjustment that reduces your reported profit and asset values. It does not involve any physical cash leaving your bank account.
How do I determine the right percentage to use?
You look at your company's historical collection data, industry averages, and the current economic climate, applying higher percentages to older invoices.
