What is GST?

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the manufacture, sale, and consumption of goods and services in India. It replaced multiple cascading taxes levied by the central and state governments.

What are CGST, SGST, and IGST?

CGST (Central GST) is collected by the Central Government. SGST (State GST) is collected by the State Government. IGST (Integrated GST) is collected by the Central Government for inter-state transactions.

How to calculate GST from total amount?

To calculate GST from total amount: Original Price = Total Amount / (1 + GST Rate/100). For example, if total is ₹1180 at 18% GST: Original Price = 1180 / 1.18 = ₹1000, GST = ₹180.

What are the current GST rates in India?

The main GST rates are 5%, 12%, 18%, and 28%. There are also special rates like 0.25%, 3%, and 0% for specific items. Some goods like gold attract 3% GST.

What is GST (Goods and Services Tax)?

GST, or Goods and Services Tax, is a comprehensive indirect tax levied on the supply of goods and services in India. Introduced on July 1, 2017, GST replaced multiple cascading taxes like VAT, Service Tax, Central Excise Duty, and others. It is a destination-based tax applied at each stage of the supply chain, with credit available for taxes paid at previous stages (Input Tax Credit or ITC).

GST Tax Slabs in India

India has a multi-tier GST structure with four main tax slabs: 5% GST applies to essential items like basic food products, common medicines, and some clothing below ₹1,000. 12% GST covers items like processed foods, mobile phones, computers, and business class airline tickets. 18% GST is the most common rate, applied to most services, electronics, capital goods, and many consumer products. 28% GST applies to luxury goods, automobiles, tobacco, and aerated drinks. Additionally, a 0% rate (exempt) applies to basic necessities like unbranded food grains, fresh vegetables, and milk.

How to Use Our GST Calculator

Using our GST calculator is straightforward. For adding GST: Enter the base price (pre-GST price), select the applicable GST rate (5%, 12%, 18%, or 28%), and click Calculate. The tool shows you CGST amount, SGST amount (or IGST for interstate), and the total price including GST. For reverse GST calculation: Enter the final price (inclusive of GST), select the GST rate, and the calculator shows you the original base price before GST was applied.

CGST vs SGST vs IGST — What's the Difference?

Under GST, taxes are split between the Central Government and State Government. CGST (Central GST) and SGST (State GST) are each half of the total GST rate and apply to intra-state transactions. IGST (Integrated GST) equals the full GST rate and applies to inter-state transactions and imports. Our GST calculator automatically splits the total GST into CGST and SGST components for intra-state transactions, making billing and accounting much simpler.
