Master Your Goods & Services Tax Calculations
In the Indian e-commerce landscape, miscalculating GST can silently wipe out your profit margins. When you sell an item on Amazon or Flipkart for ₹999 at 18% GST, you don't keep ₹999. In reality, ₹152.39 is output tax collected on behalf of the government, and the platform levies another 18% GST on their commissions and shipping fees.
ToolLab's GST Calculator is engineered specifically to help business owners, online sellers, and accountants solve this math in seconds. It bridges the gap between customer selling prices, input tax credits from your manufacturers, and deductions by marketplaces.

Frequently Asked Questions
GST Exclusive means the price entered is the base price before tax; GST is added on top to determine the final amount (Formula: Total = Base + (Base × GST%)). GST Inclusive means the entered price already includes GST (such as marketplace MRP or retail consumer prices); the tool extracts the underlying taxable base price and the tax component (Formula: Base = Total / (1 + GST%)).
For Intra-State transactions (buyer and seller in the same state), GST is split equally into 50% CGST (Central GST) and 50% SGST/UTGST (State/UT GST). For Inter-State transactions (shipping goods to a customer in another state, which represents most Indian e-commerce shipments), 100% of the tax is levied as IGST (Integrated GST).
Yes. Platforms like Amazon, Flipkart, and Meesho charge sellers referral commissions, closing fees, shipping charges, and advertising fees, levying standard 18% GST on these services. Sellers with regular GST registration can claim 100% of this 18% GST as Input Tax Credit (ITC) in their monthly GSTR-3B to offset their output GST liability on sales.
Under Section 52 of the CGST Act, e-commerce marketplace operators must deduct TCS (typically 0.5% to 1% of the net taxable sale value) before releasing payments to sellers. This deducted TCS is deposited by the platform directly to the government and gets credited into your GST electronic cash ledger, which you can use to pay your GST liability in GSTR-3B or claim as a cash refund.
The standard Indian GST slabs are 0% (exempt/essential goods), 3% (gold, silver, precious metals), 5% (footwear/apparel under ₹1,000, basic food items), 12% (apparel above ₹1,000, processed foods, certain electronics), 18% (standard rate for most consumer goods, home appliances, services, and e-commerce commissions), and 28% (luxury items, automobiles, and sin goods).
