GST Calculator

A GST Calculator is an online tool that helps businesses and individuals compute Goods and Services Tax on transactions in India. It instantly calculates the CGST, SGST, and IGST components based on the base amount and the applicable GST rate. Whether you are adding GST to a base price or extracting the original amount from a GST-inclusive price, this calculator simplifies the process and ensures accurate tax computation as per CBIC guidelines.

As per the 56th GST Council meeting and GST 2.0 framework, the revised GST rate slabs in India are: 0% (Nil-rated/exempt goods like fresh fruits, vegetables, milk, and education), 0.25% (rough diamonds), 3% (gold, silver, and jewellery), 5% (essential items like hair oil, shampoo, toothpaste, butter, and medical equipment), 18% (standard rate for cars, AC, TV, laptops, cement, and most services), and 40% (sin/luxury goods like pan masala, tobacco, aerated drinks, and large cars). The CBIC has notified these rates effective from the GST 2.0 rollout, simplifying the earlier 5-slab structure into fewer categories.

For intra-state transactions (within the same state), the GST is split equally into CGST (Central GST) and SGST (State GST). For example, on a ₹10,000 supply at 18% GST, you pay CGST ₹900 and SGST ₹900. For inter-state transactions (between different states) or imports, the full GST is charged as IGST (Integrated GST), so the same supply would attract IGST ₹1,800. This GST Calculator automatically determines the correct split based on the transaction type you select.

The Reverse GST or Remove GST feature lets you calculate the base price from a GST-inclusive amount. This is essential for traders and businesses who receive GST-inclusive invoices and need to extract the taxable value. For example, if the GST-inclusive price is ₹1,180 at 18% GST, the formula is: Base Price = Inclusive Price × 100 / (100 + GST Rate) = ₹1,180 × 100 / 118 = ₹1,000. This feature is particularly useful for input tax credit (ITC) reconciliation and filing accurate GST returns on the GST portal.

Batch GST Calculation allows you to compute GST on multiple items or invoices simultaneously, saving time for businesses with high transaction volumes. Instead of calculating GST one at a time, you can enter multiple amounts and rates, and the calculator will generate a detailed breakdown for each line item along with the total GST payable. This feature is ideal for CAs, tax professionals, and e-commerce sellers who need to process bulk invoices efficiently.

GST-exclusive price is the base price of a product or service before GST is added, while GST-inclusive price is the final amount the consumer pays after including GST. For instance, if the base price is ₹500 and the GST rate is 18%, the GST-inclusive price becomes ₹590 (₹500 + ₹90 GST). Businesses must clearly mention whether their quoted prices are inclusive or exclusive of GST on invoices, as required by the CBIC notification on GST invoicing rules.

GST 2.0, effective from September 2025, simplified the rate structure by consolidating the earlier five main slabs (5%, 12%, 18%, 28%) into three primary slabs (5%, 18%, 40%) along with special rates of 0%, 0.25%, and 3%. The 56th GST Council recommended this simplification to reduce classification disputes and compliance burden. Key changes include lowering rates on 148 common-use items (like shampoo and toothpaste from 18% to 5%) and reducing cement, AC, and TV rates from 28% to 18%, providing significant relief to consumers and businesses alike.

Yes, this GST Calculator is updated with the latest rates as notified by CBIC and the GST Council, including the GST 2.0 framework. All rate slabs — 0%, 0.25%, 3%, 5%, 18%, and 40% — reflect the current applicable rates for FY 2026-27. However, we recommend cross-verifying with the official GST portal (gst.gov.in) or CBIC notifications for any recent amendments specific to your industry or product category.
