If you’ve been selling on Amazon for a while, this won’t come as a huge surprise: every year, Amazon seems to find a new way to chip away at your profits. And 2025 is no different.
This time, it’s all about reimbursements. And unfortunately, it’s going to cost a lot of sellers thousands of dollars and affect Amazon seller FBA margins.
What Just Happened?
Amazon recently changed its reimbursement policy—effective March. In the past, if Amazon lost or damaged your inventory in their warehouse, they’d reimburse you based on the retail value of that item. That meant you got paid what the item would have sold for on Amazon.
Now? They’ll only reimburse you based on the manufacturing cost of the item. So instead of recouping your full sale price, you’re only getting back what it cost to produce.
Here’s a quick side-by-side to show how big of a deal this is:
If you’ve been seeing about 2% of your total monthly sales coming in through reimbursements (which is pretty typical for FBA sellers), this new policy could cut that number in half—or more.
And just like that, Amazon found another way to pull 1% or more from your monthly Amazon seller FBA margins.
It’s Not Just Reimbursements
This is part of a bigger trend. Amazon is slowly tightening the screws on FBA sellers, year after year.
- Last year, it was the low inventory fee.
- Then fulfillment fees went up.
- Now it’s reimbursements.
- And next year? Who knows—but fulfillment fee hikes are always on the table.
You can’t control these changes. But you can get ahead of them.
What You Can (And Should) Do About It
We’re not here to tell you to leave Amazon. That’s not realistic for most sellers.
But this is a wake-up call: if you don’t have a solid handle on your margins, these kinds of changes can quietly wreck your profits.
Here’s where to start:
1. Know Your Margins—Inside and Out
No more guesswork. You should know the numbers for every product you sell:
- Your product cost (down to the SKU level)
- Freight cost (split between sea and air if you use both)
- Amazon fulfillment fees
- Advertising spend as a percentage of revenue
That last one – Ad spend as a percent of revenue – is a number you should track every single month. It’s a great health check for your business. If it starts creeping up, it’s time to dig in and figure out why.
2. Look for Cost-Saving Opportunities
You might not be able to fight Amazon on commissions, but there are areas where you have control:
- Product cost – Can you lower your manufacturing cost by increasing your MOQ or switching suppliers? Some sellers are finding ways to reduce costs even with tariffs in place.
- Freight – Are you balancing sea vs. air strategically? Sometimes a little more planning upfront can save big on freight.
- Packaging – Could adjusting your packaging size push you into a lower fulfillment fee bracket?
That last one is often overlooked. But if your product is just barely over the size limit for the next cheapest tier, that can really add up.
3. Optimize Your Advertising
Advertising is often one of the biggest expenses for Amazon sellers—but it’s also one of the easiest levers to adjust.
- Are your campaigns performing?
- Are you overspending on low-converting keywords?
- If you’re using an agency, are they showing you month-to-month improvements, or just giving you a generic report?
Start measuring ad spend as a percent of revenue monthly. If it’s rising, figure out why. If it’s already high, find ways to make it more efficient.
4. Don’t Sleep on Fulfillment Fees
Even though fulfillment fees didn’t go up this year, they likely will next year. Be proactive.
- Check how your packaging compares to Amazon’s size and weight tiers
- Ask your supplier if they can help you shave off a little width or height
- Look at whether bundling or multi-packs could help you consolidate
These changes take effort – but they can move the needle.
The Bottom Line
Amazon’s not going to stop squeezing sellers. That’s just the reality of the FBA ecosystem now. But your response doesn’t have to be passive.
The sellers who stay profitable over the next few years will be the ones who take the time to deeply understand their numbers—and act on them.
