🏷️ What is GST?

GST (Goods and Services Tax) is a unified indirect tax system imposed on the supply of goods and services in many countries. It is aimed at creating a single, common market by eliminating the cascading effect of multiple indirect taxes such as VAT, service tax, excise duty, and others.

Under the GST regime, tax is levied at every step of the supply chain — from the manufacturer to the end consumer — but the credit of taxes paid at previous stages is available, ensuring tax is only applied on the value addition.

GST is used in countries like India, Australia, Canada, New Zealand, and Singapore. Each country has its own rules and tax rates, but the concept remains the same — to simplify tax structure, reduce corruption, and increase compliance and transparency.

GST brings consistency in taxation, encourages interstate trade, and makes it easier for businesses to operate across regions without dealing with multiple tax authorities.

🏷️ What is VAT?

VAT (Value Added Tax) is a type of indirect tax that is levied at each stage of the supply chain where value is added, from production to the final sale. It ensures that tax is applied on the value added at each point, not the entire transaction value.

Unlike sales tax, which is charged only at the final point of sale, VAT is collected at multiple stages, but businesses can claim credit for the tax they’ve already paid on purchases. This avoids tax-on-tax (cascading effect).

VAT is widely used in countries like United Kingdom, Germany, France, South Africa, and UAE. Each country sets its own VAT rates and rules, but the core idea remains the same — to maintain transparency and tax efficiency.

It promotes structured accounting and reduces tax evasion, making it a preferred tax model in many developed economies.

🏷️ What is Sales Tax?

Sales Tax is a consumption tax imposed on the sale of goods and services, typically at the final point of purchase by the consumer. It is a single-stage tax collected by retailers and remitted to the government.

Unlike VAT or GST, sales tax is only applied once and there is no system of input credit. This makes it simpler but can sometimes lead to cascading effects if not carefully managed.

It is commonly used in countries like United States, Canada, and some African nations. Rates and rules can vary significantly not just by country, but by region, state, or province.

Sales tax is easy to administer and understand for small businesses and is often preferred where tax systems are decentralized or state-controlled.

🧮 How is GST Calculated?

GST is calculated by applying the tax percentage to the base amount (exclusive) or by extracting it from the total amount (inclusive). Our calculator simplifies this with instant results — whether you're adding or removing tax.

Formula for GST Addition (Exclusive):
GST Amount = (Original Amount × GST%) / 100
Final Price = Original Amount + GST Amount

Formula for GST Removal (Inclusive):
GST Amount = Original Amount - [Original Amount × 100 / (100 + GST%)]
Base Price = Original Amount - GST Amount

Example:
If the base price is ₹1,000 and GST rate is 18%, then:
GST Amount = (1000 × 18) / 100 = ₹180
Final Price = ₹1,000 + ₹180 = ₹1,180

For inclusive GST, if the total price is ₹1,180 with 18% GST:
Base Price = 1180 × 100 / (100 + 18) = ₹1,000
GST Amount = ₹1,180 - ₹1,000 = ₹180

Our calculator supports common Indian GST slabs: 5%, 12%, 18%, and 28%. It also lets you enter any custom percentage, making it perfect for VAT or sales tax used in countries like the UK, UAE, or the USA.

Whether you're a shopper, business owner, or accountant, this tool ensures quick and accurate tax calculations without the need for manual math.

🌍 GST vs VAT vs Sales Tax – What’s the Difference?

While GST (Goods and Services Tax), VAT (Value Added Tax), and Sales Tax are all forms of indirect taxation, they differ significantly in structure, application, and regional use.

GST is a unified, destination-based tax that subsumes multiple indirect taxes like service tax, excise duty, and VAT. It is levied at each stage of supply but allows full input tax credit. Countries using GST include India, Australia, Canada, and Singapore.

VAT is also a multi-stage tax collected on value addition at each level, but its structure varies by country. It is primarily used in the UK, EU nations, UAE, and others. VAT systems are often decentralized with individual country rules.

Sales Tax is simpler and applied only once — at the final point of sale to the consumer. It is mostly used in the United States and some African regions. Unlike GST and VAT, sales tax does not offer input credit, which can lead to tax-on-tax or cascading effects.

To summarize: GST and VAT are multi-stage and credit-friendly, while sales tax is single-stage but easier to administer. Each system has pros and cons depending on the country's tax structure and governance.

Our calculator is designed to support all three — whether you're calculating 18% GST in India, 20% VAT in the UK, or 7% Sales Tax in the US. Just select your country or enter the rate manually to get started.
