Understanding GST Calculations

Exclusive to Inclusive

When you have a base amount and need to add GST to calculate the total inclusive amount:

Formula

Inclusive Amount = Base Amount + (Base Amount × GST Rate / 100)

GST Amount = Base Amount × GST Rate / 100

Inclusive to Exclusive

When you have an amount that already includes GST and need to find the base amount and GST component:

Formula

Base Amount = Inclusive Amount / (1 + GST Rate / 100)

GST Amount = Inclusive Amount - Base Amount

Frequently Asked Questions (FAQ)

What are the current GST slabs in India?

The main GST slabs are: 0% (essential items), 5% (common consumption items), 12% (processed foods, computers), 18% (most goods and services), and 28% (luxury items, sin goods). Some items have special rates like 0.25% on precious stones.

What's the difference between CGST, SGST, and IGST?

CGST (Central GST) and SGST (State GST) apply to intra-state transactions, split equally. IGST (Integrated GST) applies to inter-state transactions and imports, collected by the central government and shared with states.

How do I calculate GST from a GST-inclusive price?

To extract GST from an inclusive price: GST Amount = Inclusive Price × (GST Rate / (100 + GST Rate)). For example, for ₹1,180 inclusive price at 18% GST: GST = 1180 × (18/118) = ₹180. Our calculator automates this complex calculation.

Are there any items exempt from GST?

Yes, several items are exempt from GST including fresh fruits and vegetables, milk, bread, salt, educational services, healthcare services, and some agricultural products. These items fall under the 0% GST slab or are completely exempt.

What is the GST composition scheme?

The composition scheme is for small businesses with turnover up to ₹1.5 crore (₹75 lakh for some states). They pay GST at fixed rates (1% for manufacturers, 5% for restaurants, etc.) without input tax credit benefits. This simplifies compliance for small taxpayers.
