Bad Debt: How to Calculate Write-Offs for Your Business
Extending credit to customers can help grow your business, but it also comes with risks. Not every customer pays on time — or at all — which is where bad debt comes into play.
Knowing how to calculate and manage bad debt expenses is important. This helps businesses that rely on invoicing stay financially stable. This guide breaks down everything you need to know, from what bad debt is to the best methods for calculating and recording it.
What Is Bad Debt?
In short, it is money owed to your business that you don’t expect to collect. This usually happens when a customer fails to pay after many collection attempts. This leaves the business with an unpaid invoice. It can hurt cash flow and profits.
It can take various forms, including:
- Unpaid invoices
- Defaulted loans
- Or even contractual agreements where customers fail to fulfill payment obligations
This is a concern for businesses, especially those that use credit. It can cause revenue shortfalls and misrepresent their financial health if not managed well.

What Does This Mean for Managing Credit Risk?
Businesses that offer credit sales or payment plans are at risk of bad debt. They rely on customers sticking to payment schedules. Without good credit control policies and risk assessments, companies may face more uncollectible accounts.
This is why it is important to include these losses in financial records. We must also take steps to reduce risks from bad debt. By doing so, businesses can maintain accurate financial reporting, improve cash flow management, and safeguard long-term profitability.
Why Does Bad Debt Happen?
Bad debt doesn’t happen out of nowhere. Here are some common reasons businesses end up with unpaid invoices:
- Customer insolvency: The client goes bankrupt or runs out of funds.
- Disputed invoices: The customer refuses to pay as a result of product/service dissatisfaction or contract disagreements.
- Lack of proper vetting: Extending credit to high-risk customers without assessing their payment history.
- Economic downturns: When businesses and consumers struggle financially, payments are often delayed—or never made.
Regardless of the reason, businesses must account for bad debt to avoid overestimating their revenue.

What Is a Bad Debt Expense?
Bad debt expense is the financial cost associated with uncollectible accounts. If you have unpaid invoices, those funds must be written off as a loss, impacting your bottom line.
Bad Debt Expense Example:
Imagine a small business that provides consulting services. A client hires the firm for a project worth $10,000 and is given a 60-day credit term. However, after multiple follow-ups, the client never pays, citing financial troubles.
At the end of the accounting period, the business must recognize this $10,000 as a bad debt expense, reducing its reported income accordingly.
When it isn’t accounted for properly, it can lead to overstated income, giving a false sense of profitability. Businesses must estimate bad debt expenses and record them accurately to maintain clear financial records.
Proper accounting methods of bad debt ensure that financial statements reflect realistic revenue expectations and help businesses plan more effectively for the future.

How To Calculate Debt Expense:
1. Direct Write-Off Method
The direct write-off method records bad debt only after an invoice is deemed uncollectible. While simple, it’s not GAAP-compliant since it doesn’t match expenses with revenue in the same accounting period.
Example:
A customer fails to pay a $5,000 invoice after multiple collection attempts. You record:
- Debit: Bad Debt Expense $5,000
- Credit: Accounts Receivable $5,000
This method is straightforward but can distort financial reports if large amounts are written off unexpectedly.
2. Allowance Method
The allowance method estimates bad debt in advance, making financial statements more accurate. The two common approaches within this method include:
2.1 Percentage of Sales Method
A percentage of total credit sales is set aside as an estimate for uncollectible debts.
- Formula:
Bad Debt Expense = Total Credit Sales × Estimated Uncollectible Percentage
- Example:
Your business has $200,000 in credit sales and estimates 2% will be uncollectible.
Bad Debt Expense = $200,000 × 2% = $4,000
This estimate ensures your books reflect potential losses before they happen.
2.2 Percentage of Accounts Receivable Method
This method estimates based on outstanding accounts receivable, focusing on overdue payments.
- Formula:
Bad Debt Expense = Accounts Receivable × Estimated Uncollectible Percentage
- Example:
If accounts receivable total $150,000 and you estimate 3% as uncollectible:
Bad Debt Expense = $150,000 × 3% = $4,500
This approach ensures your allowance account reflects potential bad debt based on existing unpaid invoices.
How To Record a Bad Debt Expense
Using the allowance method, the process includes:
- Estimate uncollectible accounts using either the percentage of sales or percentage of receivables method.
- Record the estimate:
- Debit: Bad Debt Expense
- Credit: Allowance for Doubtful Accounts
- Write off a specific account when uncollectible:
- Debit: Allowance for Doubtful Accounts
- Credit: Accounts Receivable
This approach prevents sudden financial surprises when customers don’t pay.

What Is a Bad Debt Ratio and How To Interpret It?
The bad debt ratio measures uncollectible debts as a percentage of total credit sales, helping businesses assess credit risk and identify potential cash flow issues.
A high bad debt ratio suggests that a company is struggling with collections, which may indicate lenient credit policies, inefficient collection efforts, or financial instability among customers.
On the other hand, a low bad debt ratio implies that the company has effective credit control measures in place and is successfully collecting payments from clients.
- Formula:
Bad Debt Ratio = (Bad Debt Expense / Total Credit Sales) × 100
- Example:
If your bad debt expense is $5,000 and total credit sales are $250,000:
Bad Debt Ratio = ($5,000 / $250,000) × 100 = 2%
A higher ratio signals poor credit control, suggesting that adjustments may be needed in credit approval processes, collection strategies, or customer vetting procedures.
Businesses with consistently high bad debt ratios may need to reassess their invoicing policies, introduce stricter payment terms, or invest in better accounting software.
A lower bad debt ratio, however, indicates that a company has strong collection processes and effective risk management strategies, leading to better cash flow stability.
How To Prevent and Reduce Bad Debt
While bad debt is unavoidable in some cases, businesses can minimize it with smart strategies:
- Run credit checks: Vet customers before offering credit.
- Set clear payment terms: Ensure customers know when payments are due.
- Send reminders: Use invoicing software to automate follow-ups.
- Offer early payment incentives: Discounts for early payments encourage prompt action.
- Act fast on overdue accounts: The longer a debt remains unpaid, the less likely you are to collect it.
Why Is It Essential to Calculate?
Accurately calculating bad debt is crucial for maintaining financial stability. Without a proper understanding of bad debt, businesses risk overestimating their revenue, which can lead to poor financial decisions and unexpected cash flow shortages. Keeping track of bad debt helps businesses:
- Maintain accurate financial records – Ensuring that revenue projections are realistic and reflect actual earnings.
- Improve cash flow management – Anticipating and mitigating potential revenue losses caused by unpaid invoices.
- Enhance credit policies – Adjusting terms to minimize exposure to high-risk clients.
- Make informed business decisions – Planning for future investments, hiring, and expansion with greater confidence.
By regularly assessing bad debt and implementing strategies to reduce it, businesses can maintain stronger financial health and minimize unnecessary losses.

Bad Debt Calculation FAQs
The matching principle is an accounting concept that requires expenses to be recorded in the same period as the revenues they help generate. In the case of bad debt, businesses using the allowance method estimate bad debt expenses in the same period as the related sales, ensuring financial statements accurately reflect profitability.
Generally Accepted Accounting Principles (GAAP) are standardized rules and procedures for financial reporting. GAAP requires businesses to recognize bad debt expenses using the allowance method, rather than the direct write-off method, to maintain financial accuracy and consistency across periods.
Under GAAP, businesses must follow accepted accounting principles for bad debt, including:
- Estimating bad debt expenses using the percentage of sales or accounts receivable method.
- Creating an allowance for doubtful accounts to anticipate potential losses.
- Writing off uncollectible accounts in a structured manner to maintain accurate financial records.
Businesses should actively monitor and address short-term bad debt by:
- Sending frequent payment reminders and following up with overdue accounts.
- Offering discounts for early payments to encourage timely settlements.
- Utilizing automated invoicing systems to track outstanding balances and send alerts.
- Negotiating payment plans with customers facing temporary financial difficulties.
To effectively deal with bad debt, businesses should:
- Conduct thorough credit checks before extending credit to customers.
- Implement clear credit policies and payment terms to set expectations.
- Utilize invoice tracking software to monitor receivables and flag overdue payments.
- Establish a structured collections process and consider legal action if necessary for large outstanding debts.
