There's no single U.S. law that sets a legal restocking-fee percentage for ordinary store or online purchases. Retailers still take these deductions. Whether they can keep the money usually depends on the return terms shown before you paid, why you're sending the item back, state law, and whether the seller followed the policy it posted.

A label like "restocking fee" doesn't make the charge valid on its own. If your refund is already short by 15 or 20 percent, start with the policy from checkout, not with a claim that 20 percent is the national standard. This is general U.S. consumer information, not legal advice.

What the deduction is supposed to cover

A restocking fee is money kept from your refund for costs such as inspection, repackaging, cleaning, testing, or a drop in resale value. Return shipping is a separate charge.

The policy should explain both if the seller intends to collect both. When a refund statement includes a fee that never appeared in the return terms, ask the seller to identify the basis before you accept the calculation.

Look at the policy from before you paid

The useful record is the return policy on the product page, in the cart, at checkout, or on the order confirmation and receipt. A disclosure that actually helps you will state:

"Fees may apply" tells you almost nothing about the actual cost. Whether that wording satisfies a particular state's disclosure law is jurisdiction-specific. A fee first revealed after purchase is still a strong reason to request a review.

Reproduce the calculation, then match the reason

Check whether the seller used the item price, the sale price, the full order total, tax, or shipping. Those details should be defined in the policy.

If a policy clearly says a 15 percent fee applies to the item price and the item cost $200, the stated deduction would be $30. That math alone doesn't prove the fee is legally permissible. Disclosure, the return reason, state law, and the rest of the terms still matter.

A fee for an opened, non-defective item is a different case from a return involving:

Tell the seller the true reason. A merchant-caused problem may fall under warranty, contract, or consumer-protection rules rather than a change-of-mind return.

Rules people confuse with a national cap

Cars, warranties, regulated products, marketplace orders, and some services can have separate requirements. Don't assume a general retail return policy answers every dispute.

California's Car Buyer's Bill of Rights, for example, covers a two-day cancellation option for certain used vehicles priced at $40,000 or less. The cancellation fee varies with the vehicle price, from $75 to 1 percent of the purchase price. That's a vehicle-specific rule, not a restocking-fee limit for clothing, electronics, or household goods. See the California Car Buyer's Bill of Rights for the conditions.

There's no general federal percentage cap for restocking fees on ordinary retail goods. Industry averages, or claims that a retailer "usually" charges 15 to 25 percent, don't determine your rights.

State return-policy laws vary. Some states regulate how businesses disclose return policies or provide default remedies when no policy is posted. Other rules can depend on the product, the seller's promises, where the transaction took place, and whether the item was defective.

The FTC's Rule on Unfair or Deceptive Fees took effect on May 12, 2025. Its total-price requirements address mandatory fees in covered transactions, including short-term lodging and live-event ticket sales. The rule doesn't create a 20 percent ceiling, and it doesn't authorize deductions from ordinary product refunds. Read the FTC's Rule on Unfair or Deceptive Fees FAQ for its scope.

Be cautious with online state tables that list one percentage for every product. A specialized state rule may not apply to a normal retail purchase, and a rule for one type of transaction doesn't automatically transfer to another.

Signs the deduction deserves a challenge

Look closer when:

A high fee isn't automatically illegal just because it feels excessive. Ask what cost or policy term supports it, then check the law that applies to your transaction.

Evidence to keep while the return is open

Save:

If the product was defective or incorrect, describe the problem clearly and keep photographs, repair records, or other relevant documents. You usually don't need a dramatic video. Clear, dated evidence is more useful than unsupported accusations.

Dispute the fee without missing the return window

Complete the required return steps first. Use the provided label if the policy requires it, and keep proof of delivery. Don't let the stated window expire while you argue about the deduction.

Ask the seller, in writing, for the exact policy version, the calculation basis, and the condition finding that led to the deduction. A written record is clearer than a phone call.

You can use this message:

I'm requesting a review of the $[amount] restocking deduction on order [number]. I returned [item] because [reason] on [date]. The policy I saw on [date] says [short quotation]. Please identify the exact policy section, calculation basis, and condition finding supporting the deduction. If the return qualifies for an exception or the fee was not properly disclosed, please issue the remaining refund and confirm the timing.

For an Amazon, eBay, or other marketplace order, open the return or refund case through the platform. Ask for the order-specific rule that permits the deduction. A seller's policy on its own website may not control a marketplace dispute, because the platform can impose additional requirements.

Don't treat claims such as "Amazon always allows 20 percent" or "eBay allows 50 percent" as universal rules. The outcome can depend on the category, fulfillment method, seller status, return reason, item condition, and current platform terms.

If the seller won't correct an apparently undisclosed or misapplied deduction, contact the card issuer or payment provider promptly and ask whether its dispute process applies. Describe the issue as a refund or policy dispute, not as an unauthorized transaction, if you authorized the purchase.

Credit card and debit card procedures can differ, and a payment dispute isn't a guaranteed refund. Keep the policy screenshots, seller correspondence, and refund statement available.

If a business repeatedly hides fees, refuses to honor its written policy, or appears to misrepresent deductions, you can consider contacting your state attorney general or consumer-protection office. Those agencies may not obtain an individual refund, so keep preserving evidence and pursuing the merchant or platform directly.

Language that actually explains the fee

Before you buy, a useful policy answers whether the fee is percentage-based or fixed, whether it applies only to opened or used items, whether it's calculated from the item price or another amount, whether defects, wrong shipments, and transit damage are excluded, whether custom products are treated differently, who pays return shipping, and how and when the refund is issued.

A clearly written policy might say:

For non-defective opened items, the refund may be reduced by 15 percent of the item price before tax. No restocking deduction applies to defective, incorrect, or transit-damaged items. Return shipping, deadlines, and custom-item exclusions are described separately.

That's an example of useful disclosure, not a legal template or a guarantee that a fee will be enforceable.

Common questions

Is a 20 percent restocking fee automatically legal?

No. There's no universal federal 20 percent rule for ordinary merchandise. Disclosure, return reason, product type, state law, and marketplace rules all matter.

Can a retailer charge the fee for a defective product?

Don't assume so. Report the defect and ask the retailer to process the return under its defect, warranty, or incorrect-item procedure. A change-of-mind fee may not be the correct standard for a merchant-caused problem.

Can a seller charge both return shipping and a restocking fee?

They're separate charges. Whether both may be applied depends on the disclosed policy and applicable law. If one charge wasn't clearly described, ask for an itemized explanation.

What should I do before buying an item with a restocking fee?

Save the policy, calculate the possible deduction, check the exceptions, and ask support to confirm any unclear term in writing. If the potential cost changes your decision, compare another seller before you place the order.

If a restocking line already appears on your refund, pull the policy you saved, match the amount to the stated basis, and send the written review request. Finish the return so you don't miss the deadline while the seller answers.
