Quick Answer
When a company offers a warranty on its products, it must recognize the estimated warranty cost at the time of sale—not when the actual repair or replacement occurs. Under both US GAAP (ASC 460) and IFRS (IAS 37), warranty obligations are recorded as an accrued expense with a corresponding warranty liability. This article walks through the journal entries at each stage: initial recognition, actual warranty claims, and period-end adjustments.
Why Warranty Accounting Matters
Warranty expenses can be significant for manufacturers, automotive companies, and consumer electronics brands. Recording the expense when the sale occurs matches revenue with its associated costs—a core principle of accrual accounting. Failing to properly accrue warranty costs overstates early-period income and understates liabilities, which can lead to restatements and audit findings.
When to Recognize a Warranty Liability
A warranty liability should be recognized when all three conditions under IAS 37 (or the equivalent under ASC 460) are met:
- A present obligation exists as a result of a past event (the sale of the warranted product)
- It is probable that an outflow of resources will be required to settle the obligation
- A reliable estimate can be made of the amount of the obligation
For most standard product warranties that accompany a sale, these conditions are met at the point of sale. Extended warranties sold separately may be treated differently—often as deferred revenue recognized over the warranty period, similar to unearned revenue.
Journal Entry: Initial Recognition at Sale
At the time of sale, estimate the expected warranty cost and record the accrual:
Dr. Warranty Expense $5,000
Cr. Warranty Liability $5,000
To accrue estimated warranty cost on current-period sales.
How to Estimate the Warranty Cost
Estimates are typically based on historical warranty claim rates and average cost per claim. For example, if historical data shows that 2% of units sold result in warranty claims with an average repair cost of $250, and you sold 1,000 units this period:
Estimated warranty expense = 1,000 units × 2% × $250 = $5,000
Companies should review and update their estimation methods regularly to reflect changes in product quality, claim frequency, and repair costs. For related guidance on accrued liabilities, see our article on journal entries for accrued expenses.
Journal Entry: Actual Warranty Claim
When a customer makes a warranty claim and the company incurs repair or replacement costs:
Dr. Warranty Liability $1,200
Cr. Inventory (or Cash / AP) $1,200
To record actual warranty claim—replacing a defective component from inventory.
Notice that the expense was already recognized at the time of sale. The actual claim reduces the liability, not the current-period expense. This is the key distinction between accrual-basis and cash-basis warranty accounting.
Types of Warranty Costs
The credit side of the actual claim entry depends on the nature of the cost:
- Parts from inventory: Credit Inventory
- Labor paid in cash: Credit Cash
- Third-party repair services: Credit Accounts Payable

Journal Entry: Period-End Adjustment
At the end of each reporting period, compare the warranty liability balance to the updated estimate of remaining warranty obligations. If actual claims have been lower than expected, you may need to increase the liability. If claims have been higher, you may need to adjust upward to cover remaining exposure.
Increasing the Warranty Liability
Dr. Warranty Expense $3,000
Cr. Warranty Liability $3,000
To increase the warranty liability based on revised estimates of remaining claims.
Decreasing the Warranty Liability
If the liability is overstated (e.g., product quality improved and claim rates dropped):
Dr. Warranty Liability $2,000
Cr. Warranty Expense $2,000
To reduce the warranty liability to reflect lower-than-expected claim rates.
Extended Warranties vs. Standard Warranties
Standard warranties that are included with the product at no additional cost are accounted for as described above—expense at sale, liability for estimated costs. Extended warranties sold as separate contracts are treated differently under ASC 606:
- The customer payment is recorded as deferred (unearned) revenue
- Revenue is recognized over the coverage period on a straight-line basis (or another systematic method)
- Actual claim costs are recognized as expense when incurred
This distinction is critical because mixing up the two treatments will produce incorrect revenue and expense timing on your financial statements.
Disclosure Requirements
Under both US GAAP and IFRS, companies must disclose significant warranty obligations in the notes to the financial statements. Typical disclosures include:
- The accounting policy for warranty costs
- The method used to estimate the warranty liability
- A rollforward of the warranty liability balance (beginning balance, additions, utilization, adjustments, ending balance)
- Any significant changes in estimation methods or assumptions
Common Errors to Avoid
- Recording warranty expense at claim time: This violates the matching principle and delays expense recognition until the claim is filed, which may be months or years after the sale.
- Ignoring FBA or third-party warranty obligations: If your company is responsible for warranty costs on products fulfilled by third parties, the same accrual rules apply.
- Failing to update estimates: Historical claim rates change. Using outdated assumptions leads to over- or under-accrued liabilities that auditors will flag.
- Not separating standard and extended warranties: Each type has a distinct accounting treatment that must be applied consistently.
Key Takeaways
- Recognize warranty expense at the time of sale, not when claims are made
- Use historical data to estimate claim rates and average cost per claim
- Actual claims reduce the liability, not the current-period expense
- Review and adjust the warranty liability at each reporting period
- Extended warranties are accounted for differently from standard warranties under ASC 606
- Disclose warranty policies, estimation methods, and liability rollforwards in financial statement notes
