What people are saying

"I check my Etsy margins before every product launch. My pricing is my competitive edge — I'm not handing it over to a calculator that stores everything. This runs in my browser and that's exactly where my numbers should stay."

"The dropshipping margin calculator is the first one I've found that includes ad spend in the calculation. Most just do product cost minus selling price. This one shows the real number — and it does it without asking me to sign up for anything."

"I switched from FBA to FBM last quarter and the Amazon calculator helped me model both scenarios side by side. Saved me from a $3,000/month mistake. No login required, no data stored — just the math I needed."
