Frequently asked questions
Quick answers before you start.
How do I add GST to a price?
If your amount is exclusive of GST, multiply by the rate and add it on top. At 18%, a ₹10,000 amount becomes ₹11,800. This calculator's 'exclusive' mode does exactly that.
How do I remove GST from a price?
If your amount already includes GST, divide by (1 + rate/100) to find the base amount. At 18%, ₹11,800 inclusive is ₹10,000 base plus ₹1,800 GST. Use the 'inclusive' mode.
Which GST rate applies to my product?
India has four main slabs: 5% (essentials), 12% (processed goods), 18% (most services), and 28% (luxury items). Many services fall under 18%. Confirm the correct HSN/SAC code with your accountant for your specific case.
