GST Calculator – Simplify Your Tax Computations
The Goods and Services Tax (GST) revolutionized India's indirect tax structure, replacing a web of multiple taxes with a single, unified system. However, calculating the exact tax component—whether you are a business owner pricing your goods or a consumer verifying a bill—can still be confusing.
Our GST Calculator is designed for instant accuracy. Whether you need to add GST to a base price (Exclusive) or remove GST from a final price (Inclusive), this tool handles the math for all standard tax slabs (5%, 12%, 18%, 28%) in a split second.
Inclusive vs. Exclusive GST: What's the Difference?
Understanding how GST is applied is crucial for correct billing and budgeting.
GST Exclusive
This means the tax is added to the product's cost.
Example: Product Cost ₹100 + 18% GST = Final Price ₹118.
Use this when you are a seller determining the Maximum Retail Price (MRP).
GST Inclusive
This means the tax is included in the final price.
Example: Final Price ₹118 (at 18% GST) means the Product Value is ₹100.
Use this to calculate the pre-tax cost of an item.
Tax Components
CGST + SGST: For sales within the same state (Intra-state).
IGST: For sales between different states (Inter-state).
Input Tax Credit
Registered businesses can claim the GST paid on purchases (Input Tax) as a credit to set off against the GST collected on sales (Output Tax).
Frequently Asked Questions (FAQs)
