Understanding GST Calculation

1. GST Exclusive (Add GST)

When GST is not included in the price. Use this for invoicing.
Formula: GST Amount = (Original Cost × GST Rate) / 100

2. GST Inclusive (Remove GST)

When GST is already part of the total price (MRP). Use this for reverse calculation.
Formula: GST Amount = (Total Price × GST Rate) / (100 + GST Rate)

Frequently Asked Questions

To calculate GST on a product, multiply the base price by the GST rate and divide by 100. For example, if a product costs ₹1,000 and the GST rate is 18%, the GST amount is ₹180, making the total ₹1,180. Use our calculator above for instant results.
GST Exclusive means the GST is added on top of the base price (Total = Base + GST). GST Inclusive means the GST is already included in the displayed price and you need to extract it (Base = Total × 100 / (100 + GST Rate)). MRP prices are typically GST-inclusive.
India has four main GST slabs: 5% (essential items like food, medicines), 12% (processed foods, computers), 18% (most services, capital goods — the most common slab), and 28% (luxury items, automobiles, consumer durables). Some items like fresh vegetables and milk are GST-exempt (0%).
CGST (Central GST) and SGST (State GST) are charged equally on intra-state transactions — each is half the total GST rate. IGST (Integrated GST) is charged on inter-state transactions and equals the full GST rate. For example, 18% GST intra-state = 9% CGST + 9% SGST.
To extract GST from a total (inclusive) amount, use the formula: GST Amount = Total Price × GST Rate / (100 + GST Rate). For example, if the total price is ₹1,180 at 18% GST: GST = 1180 × 18 / 118 = ₹180. The base price is ₹1,000.
