Add GST to a base price or pull it out of an inclusive one — all slabs, with the CGST/SGST split — instantly as you type.
This page opens the Seller Calculators with the right mode pre-selected. Three calculators every online seller needs. Marketplace Profit shows your true per-order profit: it deducts commission, fixed/closing fees, shipping, and the GST/VAT charged on those fees (18% in India, your local rate elsewhere), then shows your settlement and margin in a transparent line-by-line breakdown. The Tax calculator adds GST/VAT to a base price or extracts it from an inclusive one — any rate, with the CGST/SGST split shown for Indian rupees. Margin & ROI converts cost and selling price into margin, markup and return on investment.
Because marketplaces charge GST (typically 18%) on their fees, and add fixed/closing and shipping fees. The breakdown shows each deduction separately so nothing is hidden.
