calkar.in is a set of free calculators and guides for people who sell online in India: on Meesho, Amazon, Flipkart or their own store.
I’m Adhil , and I run YAAX, a sole proprietorship based in Malappuram, kerala . I’ve been selling on Meesho, Amazon and Flipkart since january-2026. In that time I’ve learned that the hardest part of selling online isn’t finding products. It’s working out what you actually earn after commissions, shipping, returns, RTO, GST TCS and TDS.
Most calculators online are either generic, built for other countries, or use fee rates that are years out of date. I built calkar.in to fix that for myself first, and then for other sellers.
What makes these tools different
- Every rate comes from the official source, linked on the page, with the date we last checked it.
- Every calculator shows its working, so you can check the maths yourself.
- The guides come from my own seller panels and real orders, not from rewritten articles.
