About This Tool
The GST Calculator adds or removes Goods and Services Tax from any price with a single click. Choose between two modes: add GST to a base price to find the total, or extract the GST component from a tax-inclusive price to find the original amount.
Common GST rates (5%, 12%, 18%, 28%) are pre-loaded for quick selection, matching the rate slabs used in India and similar tax systems worldwide. You can also enter any custom rate to match your jurisdiction's requirements.
This tool provides a clear three-line breakdown showing the base price, the GST amount, and the final total. It is used daily by business owners preparing invoices, accountants reconciling tax-inclusive receipts, and consumers who want to understand the tax component of their purchases.
