Fitness Trackers

Here's something I wish someone had told me before I started selling fitness trackers: you're not competing on product alone. You're competing on fulfillment strategy. Fitness Trackers at $34.99 might seem straightforward, but the difference between FBA and FBM can be the difference between profit and loss.

I talk to a lot of sellers who want to know if fitness trackers is still worth selling. Short answer: yes, but only if you pick the right fulfillment mode. Let me show you why.

Here's the thing about selling fitness trackers online — most sellers get the pricing right but completely underestimate the fee stack. A $34.99 product sounds profitable until you layer on fulfillment, referrals, storage, and advertising.

Now here's where the money actually goes when you sell fitness trackers on Amazon FBA. Your landed cost (FOB + freight) is about $3.3. The FBA fulfillment fee depends on the size — for a product at 6"×4"×1" and 0.08 lbs, it adds a meaningful amount. Then comes the 15% referral fee ($5.25), advertising at 25% ACoS ($8.75), and return losses at 10% ($3.5). All of that adds up fast.

I've tested both FBA and FBM for fitness trackers, and here's what I found. FBA gives you the Prime badge and convenience, but for a $34.99 product, the fees consume a bigger percentage than most people realize. FBM saved me about 9% on fees, though you have to handle shipping yourself. My advice? Start with FBA, then experiment with FBM once you hit consistent volume.

A few things I'd tell anyone getting into fitness trackers: (1) Watch your return rate — 10% is the benchmark, and if you're above that, check your listing photos and product quality. (2) If you're selling internationally, don't assume US pricing works in other markets — our region comparison above shows how margins shift across US, DE, and JP. (3) Bundle pricing at $41.99 for a 2-pack often doubles your margin without doubling your costs. No extra advice needed — just run your numbers before you order inventory.

At the end of the day, fitness trackers can be a solid category if you're smart about fulfillment. Use the calculator above to plug in your actual numbers — this data is just a starting point based on typical products. Your specific dimensions, costs, and volume will give you a much clearer picture.
