I have been using for 6 months and it's super accurate compared to actual fees when the orders come through. I checked like 20 products against my actual seller central data and the estimate were within a few cents every time. Some calculators are way off and give you false confidence, this one is reliable

You'd think something this useful would be clunky or annoying. But it just sits quietly until you need it. Does not slow my browser or pop up randomly. When I run numbers, it's right there. Like that it has a clean interface. It feels built like someone who has actually sold on Amazon

Very simple, clean and accurate. It doesn't try to sell you anything mid calculation. I literally click the extension on a product, punch my numbers, and it tells me ROI, marging, and profit under 5 seconds. That's all I want

If I had this two years ago I wouldn't have blown 10k on dead inventory. I used to just eyeball profit margins. Stupid, I know. But margins look good till you add shipping, storage, Amazon fees, and realize you're making 0.76 per unit. This thing spells it out. One click, type in COGS, and it smacks you with reality. It made me kill two SKUs I was emotionally attached to. Best tough love I've gotten all year.

It's great when it works, but... not so much when it decides to show the "can't display results at the moment" or whatever. Frustrating and I have to switch browsers to use it.

The best FBA calculator out there. It’s helped me make incredibly smarter pricing decisions based on super granular information.

Although it’s free I want to say it’s worth every penny. Lol. I love this tool man. Perfect seller tool.

I’m a seasonal seller and there are several times a year when I need to break down my costs. This tool is one of the best in my stack. I honestly love it way too much.

My partner and I run multiple businesses on Amazon, and this tool has helped us make sure we stay on top of the number for all.

Used this to compare my FBA and FBM profits. Helped me understand which model to pivot to. My projections for Q1 are looking great. Recommend this extension. 5 out of 5.

It’s helped our 5 member team cut down on unnecessary costs and stay competitive. It’s perfect.
