KalkuleX is the flagship product developed by IQ3 Inc, a Delaware-based startup now in its fifth year of innovation. What started as a simple observationthat eBay sellers were losing money due to miscalculated feeshas evolved into the most sophisticated profit optimization platform in the e-commerce industry.
Understanding eBay's fee structure is notoriously difficulteven for experienced sellers. Between fluctuating final value fees, category-specific charges, and hidden costs from promoted listings, profits can disappear faster than you realize. Add in underestimated shipping fees or miscalculated volumetric weight, and what looked like a winning sale can quickly become a loss.
Studies show that 73% of eBay sellers miscalculate their actual profits, with the average seller losing 12-18% of potential earnings due to pricing errors. That's thousands of dollars left on the table every year.
KalkuleX was born out of this chaos. It's a tool designed specifically for sellers who want clarity, control, and confidence. By accurately calculating costsincluding fees, freight, taxes, and marginsKalkuleX helps you make smarter pricing decisions and protect your bottom line in real time.
