Frequently Asked Questions
What are the GST slabs in India?
India has four main GST slabs: 5% (essentials like food grains, healthcare), 12% (processed food, mobile phones), 18% (most goods and services), and 28% (luxury goods, vehicles, tobacco). Some items are exempt (0%).
How do I add GST to a price?
Multiply the base price by (1 + GST rate/100). For 18% GST on ₹1,000: 1,000 × 1.18 = ₹1,180 is the GST-inclusive price. The tool calculates this instantly.
How do I remove GST from an inclusive price?
Divide the GST-inclusive price by (1 + GST rate/100). For ₹1,180 inclusive of 18% GST: 1,180 ÷ 1.18 = ₹1,000 is the base price before GST.
