Calculate GST amount and total price with our free GST Calculator. Supports inclusive/exclusive mode, multiple currencies, and real-time updates.
Managing taxes efficiently is essential for every business owner, professional, or consumer. The GST Calculator is an easy-to-use tool designed to help you calculate Goods and Services Tax (GST) quickly and accurately. With this calculator, you can determine how much GST applies to a particular product or service and find the total amount you need to pay or charge. Whether your prices are GST inclusive or exclusive, this tool simplifies the process and provides instant results.
What is a GST Calculator?
A GST Calculator is a digital tool that helps you compute the GST amount and total price based on the applicable GST rate. It’s especially useful for small businesses, shopkeepers, freelancers, and even customers who want to understand how much tax they’re paying on goods or services. The calculator eliminates manual calculations and errors, ensuring you always get accurate figures within seconds.
Using the calculator, you can easily switch between GST inclusive and exclusive modes, choose your preferred currency, and apply preset GST rates like 5%, 12%, 18%, or 28%.
How the GST Calculator Works
The GST Calculator functions using two main inputs:
- Amount: The base price (excluding or including GST) of a product or service.
- GST Rate (%): The applicable GST percentage rate (such as 5%, 12%, 18%, or 28%).
You can also select a currency symbol (₹, $, €, £, ¥, or A$) to suit your regional preference. Once the values are entered, the calculator instantly provides both GST amount and total price.
Let’s understand how the calculator works in both scenarios:
1. GST Exclusive Calculation
If your entered price is excluding GST, the calculator applies this formula:
- GST Amount = Base Amount × GST Rate / 100
- Total Price = Base Amount + GST Amount
Example:
Base Amount = ₹1,000
GST Rate = 18%
GST Amount = 1,000 × 18 / 100 = ₹180
Total Price = ₹1,000 + ₹180 = ₹1,180
2. GST Inclusive Calculation
If your entered price already includes GST, the calculator finds the base price and GST portion using:
- GST Amount = Total Price × GST Rate / (100 + GST Rate)
- Base Amount = Total Price – GST Amount
Example:
Total Price = ₹1,180
GST Rate = 18%
GST Amount = 1,180 × 18 / (100 + 18) ≈ ₹180
Base Amount = ₹1,180 – ₹180 = ₹1,000
This dual functionality makes the GST Calculator versatile for all types of billing and pricing needs.

Common GST Slabs in India
India follows a multi-tier GST structure. Here are the most common GST rates:
- 5%: Essential goods like household items and food products.
- 12%: Packaged food and processed items.
- 18%: Standard goods and services like electronics or restaurant bills.
- 28%: Luxury goods such as cars and high-end accessories.
The GST Calculator allows you to apply these slabs directly or input a custom percentage as per your requirements.
Real-Life Example
Suppose you own a mobile accessories shop. You sell a charger for ₹800 with a GST rate of 18%.
- GST Amount = ₹800 × 18 / 100 = ₹144
- Total Price = ₹800 + ₹144 = ₹944
If you’re selling an item with an inclusive price of ₹944, the calculator helps you identify that ₹144 is the GST portion and ₹800 is the actual product price.
This transparency helps both buyers and sellers understand the tax impact clearly.
