Frequently Asked Questions

What is GST and how is it calculated?▾
GST (Goods and Services Tax) is India's unified indirect tax that replaced multiple taxes like VAT, service tax, and excise duty. For GST-exclusive calculation, GST = Base Price × GST Rate. For GST-inclusive calculation, Base Price = Total Price ÷ (1 + GST Rate). For example, 18% GST on ₹1,000 = ₹180, making the total ₹1,180.
What is the difference between CGST, SGST, and IGST?▾
For intra-state transactions (within the same state), the GST rate is split equally between CGST (Central GST) and SGST (State GST). For inter-state transactions (between different states), the entire GST is charged as IGST (Integrated GST). For example, 18% GST intra-state = 9% CGST + 9% SGST, while 18% inter-state = 18% IGST.
Which GST slab applies to my product or service?▾
India has six GST rates: 0.25% (rough diamonds), 3% (gold, silver), 5% (packaged food, economy transport), 12% (processed food, mobile phones), 18% (most goods and services, IT, restaurants), and 28% (luxury goods, cars, tobacco, aerated drinks). Essential items like fresh food and healthcare are GST-exempt (0%).
What is GST Cess and when does it apply?▾
GST Cess is an additional tax over and above the standard GST rate, applied on specific luxury and demerit goods like tobacco products (up to 290% cess), aerated drinks (12% cess), luxury cars (up to 22% cess), and coal (₹400/tonne). The cess goes to a compensation fund for states.
Can I use this for GST return filing?▾
This calculator helps you verify GST amounts and generate invoice-style breakdowns with CGST/SGST/IGST splits. While it's useful for cross-checking figures before filing GSTR-1 or GSTR-3B, actual GST return filing must be done through the official GST portal (gst.gov.in).
Is this calculator free to use?▾
Yes, completely free with no signup required. All calculations happen instantly in your browser. You can add multiple line items, switch between tax modes, and see detailed breakdowns — all without any data being sent to a server.
