A GST calculator is a tool that helps you calculate goods and tax (GST) for your products or services. If you’re registered for GST, you have to include GST on your invoices, unless you sell exempt goods or services.
The calculator helps you work out the price including or excluding GST, and to comply with the rules and regulations in India.
The GST slab varies depending on what you’re selling. In these examples we’ve used a GST slab of 18%.
Add GST to the price
To figure out the total price with GST, simply multiply the original price by 1.18.
₹100 x 1.18 = ₹118
Work out the GST amount to add
To figure out how much GST you’ll be charging, simply multiply the original price by 0.15.
₹100 x 0.18 = ₹18
Exclude GST from the price
If you want the price without GST, divide by 1.18.
₹118 / 1.18 = ₹100
Work out the GST amount that was added
To figure out how much GST was included in the price you can take the price with GST minus the price without GST.
₹118 – ₹100 = ₹18
| Type of items | GST slab | Reasoning |
| Essential items such as basic foods like fish, meat, dairy, vegetables, bread, salt etc. | 0% | Essentials are tax-free—also called GST exempt—to keep them affordable |
| Household necessities like sugar, tea and coffee, and transportation | 5% | Certain necessities are taxed at the lowest rate so they remain accessible |
| Standard goods like construction, business class air travel, and processed foods like dried fruit confectionary | 12% | These are taxed at a medium rate to keep them affordable |
| A wide range of goods and services such as electronics, insurance, TVs, commercial vehicles, banking services | 18% | Common items are taxed at the most common rate of GST |
| Consumer durables, luxury items, entertainment and gambling | 28% | These are premium goods |

There are four types of GST in India.
Sales across states (inter-state)
Integrated goods and services tax (IGST) is collected by the central government.
Sales within states (intra-state)
Central goods and services tax (CGST) is collected by the central government.
State goods and services tax (SGST) is collected by the state government.
Both rates are usually equal, so if the GST rate is 18%, the central government charges 9% and the state government charges 9%.
Sales in union territories
Union territory goods and services tax (UTGST) is collected by the central government.
Usually freelancers charge 18% GST on their services. If you want to calculate the GST, you can either use a GST calculator or you can multiply the original price by 1.18:
