Recording Warranty Expenses and Liabilities

What is a warranty?

Most of the products we purchase come with some type of warranty. A warranty is guarantee that the manufacturer of the product will repair or replace the product for a certain period of time. In 2013, I bought my husband a Weber Smokey Mountain Cooker, because he likes to smoke meat and I like to eat smoked meat. It works out well for everyone! This product came with a 10-year limited warranty. That means that if something breaks because of a defect (not normal wear and tear or abuse), the company will replace the part that broke. This was not something that we purchased in addition to the product. It came with the product as part of the purchase.

Do not confuse standard warranties with extended warranties that consumers purchase for an additional fee.

Why must companies record a liability?

When a company provides a warranty with its product, the company has an obligation to repair or replace the product if it is defective. That obligation generates a liability at the time the product is sold because the company has a liability that starts when the product is sold.

When must the company record the warranty expense?

The matching principle states that a company must match revenue with expenses. If Weber sells a smoker in 2013 but expenses a warranty claim in 2020 (remember it is a 10-year warranty), the company is violating the matching principle. The warranty expense occurs because the sale took place. The expense is a cost of the sale and therefore should be matched with the revenue generated by that sale.

How does the company record an expense for a repair that has not happened yet?

It might seem a little strange to ask a company to record an expense when it hasn’t occurred yet but we have done this many times in accounting. Accounting requires the use of many estimates. Warranties are no exception. Remember when we recorded Bad Debt Expense under the allowance method and had to estimate the expense at the time of the sale? Warranty expense is very similar. We must estimate the expense based on previous company history and record the journal entry.

In order for a company to estimate the warranty expense and liability, we need to know three things:

  • How many units of the product were sold during the period of time we need to record?
  • What percentage of the products sold will need repairs or replacement based on previous experience?
  • What is the average cost of the repair or replacement under warranty?

All of this information is readily available to managers and accounts within the company. To calculate the warranty expense, first figure out how many products will need repair or replacement:

Total number of units sold X Percentage of units that are defective

Next, calculate the cost of repair or replacement for those units:

Units needing repair or replacement X cost per unit to repair or replace

Let’s look at an example to see how a company would estimate and record warranty expense.

Example #1

Hydration-on-the-Go makes stylish water bottles. Each water bottle includes a one-year warranty against manufacturing defects. Based on five years worth of data, the company estimates that 3% of the water bottles sold will be returned because of a defect. When this occurs the company replaces the water bottle. Each water bottle costs $4 to produce. 

In 2013, the company sold 25,000 water bottles. Record the amount of warranty expense that the company should record for 2013.

To record the warranty expense, we need to know three things: units sold, the percentage that will be replaced within the warranty period, and the cost of replacement.

First, calculate the number of units the company believes will need to be replaced under warranty.

25,000 water bottles sold x 3% defect rate = 750 water bottles potentially defective

Next, calculate the cost of replacing those potentially defective water bottles.

750 water bottles potentially defective x $4 replacement cost = $3000 estimated warranty liability


That is all there is to it. Recording the expense and the liability as an adjusting journal entry.

Recording customer warranty claims

When a customer requests a repair or replacement under warranty, the customer files a claim. The company must record this claim. Every time the company fulfills a claim, a portion of the warranty liability is also fulfilled. In other words, every time a claim is fulfilled, the company must decrease the amount of the liability by the cost of fulfilling the claim.

There are a number of ways that the company can fulfill a claim. It can replace the item with an item from inventory, therefore decreasing inventory. The company could repair the product using parts from inventory and outside labor (which would require cash) or inside labor (wages payable). Always record the replacement or repair at cost, not at the retail value of the item or parts.

Example #2

On February 1, Hydration-on-the-Go received 14 water bottles in the mail that had been returned by customers to be replaced under warranty. Each water bottle costs $4 to produce and sells for $9. Record the entry for the fulfillment of the warranty claims.

The problem is asking us to record the warranty claim. When the company fulfills a warranty claim, we need to debit the estimated warranty liability. This is because part of the warranty obligation is being fulfilled. The amount of liability is decreasing.

Now to determine the account to credit. Ask yourself how the liability is being fulfilled. How is the company fulfilling the liability in this case? The company is replacing the water bottle. Water bottles are the product that the company sells. They are inventory. Therefore, we will reduce inventory by the amount that the bottles cost. When we use inventory to fulfill the warranty liability, the value of inventory falls.

How much should we record as the cost of the water bottles? If we are removing them from inventory, we should remove them at cost. Therefore, use $4 per water bottle.

14 water bottles x $4 per water bottle = $56 cost of inventory

We have all the information we need to record the journal entry.

    Thanks for this valuable information , an appreciate your efforts
    Could you please help by post full journal entry transaction of Labor and parts which consumed to settle this type of liabilities

    • Kristin says:

      In the last entry, you would replace inventory with the specific costs you had. Parts would come from inventory so that would not change. You would just need to add the labor.

    Dr. Warranties liability
    Cr. Spareparts inv.
    Cr. Wage payable
    Or. Cr. Cash (in case of external labour)

    • Kristin says:

      This could work depending on the circumstances. It’s hard to give one answer to a question like this because there are so many variables here.

  • Sean says:

    What are the journal entries if you are refurbishing the returned water bottles? I assume you need to value the returned water bottle before it is fixed, then capitalize the labor/materials that are required to get the bottle back to the appropriate condition. I would guess that valuing a broken product is not easy to do…..

    *Receive the broken bottle*
    DR: Broken Product -Inv
    CR: Refund Liability

    *Fix the broken bottle*
    DR: Direct Labor -Inv
    CR: Payable
    DR: Direct Material-Inv
    CR: Payable

    • Kristin says:

      You would need to add the additional cost for fixing the broken bottle to the original cost of the bottle. Essentially, the broken bottle is treated as WIP with additional materials, DL, and OH added.

  • Ngoc Nguyen says:

    Thanks for your guidance very clear and helpful.

  • Thank you for the information above, I do though have a question about how this impacts the P&L? Example: Warranty provisions of 100 is expensed, then after the warranty period, only 40 was claimed and therefore 60 is left. Are these 60 transferred back into the P&L and affecting the EBIT margin positively? I mean, first you count 100 as expenses, then only 40 is used and then finally the 60 is left. This cash is then treated as profit, but where in the P&L does the 60 figure?

    • Kristin says:

      Think of the other side of the original entry: debit Warranty Expense, credit Warranty Liability. The $60 stays in the Warranty Liability account until it is needed. Not all warranties are one year and there are still potential claims outstanding after the fiscal year ends. The expense is still $100 and because of the matching principle, it must be recorded in the year of the sale, however, the liability still exists because there is still product under warranty.

      • Christine Hawley says:

        what if the warranty period ends and there is still a liability remaining in the warranty liability account. In other words, you initially overestimated your future expenses when the liability was recorded. Do you reduce the liability and decrease expense in the period that the warranty expires?

        • Kristin says:

          If the warranty period ends, you would need to make an adjustment to decrease the warranty liability and record revenue for the liability not incurred.

  • Priya says:

    why in example 1, it comes to 750 bottles when 3% of 250000 is equal to 7500??

  • Hasnat says:

    Thanks, Kristin for your valuable discussion. I have a few questions in my mind. What will be the journal entry when we receive the faulty products from the customer? Should we treat this as a sales return? Or we we have to value the faulty product at the point of return and then recorder into the inventory as damage material. My concern is if i want to keep track on faulty return what will be right accounting and valuation. Appreciating your thoughts.



    • Kristin says:

      The entry would be the same except for one possible modification. If you want to track the defective merchandise (which is currently in COGS), you would make an entry to some sort of faulty merchandise account. Since you aren’t planning to sell the merchandise, it doesn’t make sense to put it back into inventory. It can be left in GOGS or moved to an account so you can specifically track defective merchandise.

      • Hasnat says:

        Thanks, Kristin for your prompt response. In that case, what will be the valuation of the faulty product? Should we value faulty one at the original cost which already charged at COGS? or a new valuation is required at zero or $1. In my understanding, a new valuation is required as a faulty product must carry less or no value than the original condition. If we reverse the earlier entry in COGS at the original price, it will significantly increase the revenue that particular year. Appreciate your thoughts.

        • Kristin says:

          Whatever was charged to COGS originally should be the amount moved.

          Reversing the COGS portion of the entry should not affect revenue. It also should not affect profit because you are just changing the account the amount is sitting in. If the product was $50 and you moved it to a different account, say defective merchandise expense, COGS would decrease by $50 but defective merchandise inventory would increase by $50.

  • Mub says:

    Hi, how would you account for a cost of warranty that was more than originally anticipated in the warranty provision? For example, if I set up a warranty provision of $1000 but at the end of the year the cost to actually service the warranty ended up being $1500. What would be the journal entries?

    Thank you

    • Kristin says:

      You would need to record an entry to bring the balance back to zero (debit expense $500, credit liability). You can either add this to next warranty liability entry you make or add as a separate entry. It’s similar to recording bad debt under the allowance for doubtful accounts method.

      • Farzona says:

        Thank you Kristin!
        And what about the exact opposite of this case, say the warranty liability was estimated as $10,000 and the claim was for $5,000. How do we zero out the liability account? Should I credit it to the expense (p&l) or record as other income from unclaimed warranty?
        Please advise!

  • Eric says:

    Thanks! Very helpful!

  • Rachael says:

    I have a question regarding this: ” Always record the replacement or repair at cost, not at the retail value of the item or parts.”
    We supply part A to customer at retail $20 (credit to customer) but part A cost is $10 – how would that be recorded?

    • Kristin says:

      So you essentially give the customer a coupon to get the product? If so, then it still only costs you $10. The face value of the credit may be $20 but you are still only providing a $10 part.

  • Aimen says:

    Can you please describe the accrued warranty expense account on balance sheet.

  • Mercedes says:

    Very helpful information. However, how do I record an entry when an tractor I bought had defects after a month and the dealership repaired it for $13,000. It was covered under warranty. Is there something I need to record at my end?
