📐 GST Calculation Formulas
GST Exclusive (Add GST)
GST Amount = (Base Price × GST Rate) ÷ 100
Total Price = Base Price + GST Amount
Example: ₹1000 at 18% GST = (1000 × 18) ÷ 100 = ₹180 GST, Total = ₹1180
GST Inclusive (Extract GST)
Base Price = (Total Price × 100) ÷ (100 + GST Rate)
GST Amount = Total Price - Base Price
Example: ₹1180 with 18% GST = (1180 × 100) ÷ 118 = ₹1000 base, GST = ₹180
GST Rates in India
📚 Understanding GST in India
GST (Goods and Services Tax) is India's comprehensive indirect tax system that replaced multiple cascading taxes. Implemented on July 1, 2017, GST unified the Indian market by creating a single tax structure across the country.
Why GST matters for your business: GST eliminates the "tax on tax" problem and makes pricing more transparent. As a business owner, you must charge GST on your products/services and can claim input tax credit on GST paid for business purchases.
CGST, SGST, and IGST explained: For sales within your state, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state sales, you charge IGST (Integrated GST). The total rate remains the same - only the collection mechanism differs.
When to register for GST: Registration is mandatory if your annual turnover exceeds ₹40 lakhs for services (₹20 lakhs for special category states) or ₹40 lakhs for goods. E-commerce sellers must register regardless of turnover.

Frequently Asked Questions
How to calculate GST in India?
To calculate GST, multiply your base price by the GST rate and divide by 100. For example, if your product costs ₹1,000 and GST is 18%, the GST amount is (1000 × 18) ÷ 100 = ₹180. The total price becomes ₹1,180. Use our free GST calculator above for instant results.
What are the different GST rates in India?
India has four main GST slabs: 5% (essential items like packaged food), 12% (processed food, computers), 18% (most services, capital goods), and 28% (luxury items, automobiles). Some items like fresh produce are exempt (0% GST). Most business services fall under the 18% category.
How do I calculate GST inclusive price?
To extract GST from an inclusive price, use this formula: Base Price = (Total Price × 100) ÷ (100 + GST Rate). For example, if your total is ₹1,180 with 18% GST: (1180 × 100) ÷ 118 = ₹1,000 base price. GST amount = ₹1,180 - ₹1,000 = ₹180.
What is 18% GST on ₹1000?
18% GST on ₹1,000 equals ₹180. The calculation is: (1000 × 18) ÷ 100 = 180. Your customer will pay a total of ₹1,180 (₹1,000 base price + ₹180 GST). This is the most common GST rate in India for services and goods.
How do I remove GST from total amount?
To remove GST from a total amount, divide the total by (1 + GST rate as decimal). For 18% GST on ₹1,180: Base = 1180 ÷ 1.18 = ₹1,000. GST = ₹1,180 - ₹1,000 = ₹180. Our calculator handles this automatically when you select "GST Inclusive" mode.
Is this GST calculator accurate for business use?
Yes, this GST calculator uses official GST formulas approved by the Government of India. It's accurate for invoicing, pricing, and tax planning. However, for official GST filing and returns, always use the GST portal at gst.gov.in and consult a tax professional for complex scenarios.
Can I use this calculator for CGST and SGST?
Yes. For intra-state transactions, GST is split equally into CGST and SGST. If you calculate 18% GST as ₹180, it means ₹90 CGST + ₹90 SGST. For inter-state transactions, the full 18% (₹180) is IGST. Our calculator shows the total GST amount.
Do I need to register to use this GST calculator?
No registration or signup required. This is a completely free tool that works instantly in your browser. All calculations happen on your device, and we don't store any of your data. Use it unlimited times for all your GST calculation needs.
