Formula & Method
Add GST: GST Amount = Base x (Rate / 100) and Total = Base + GST Amount
Remove GST: Base = Total / (1 + Rate / 100) and GST Amount = Total - Base
For intra-state sales, GST splits equally into CGST (Central GST) and SGST (State GST), each at half the total rate. Inter-state sales use IGST at the full rate.
Examples

| 1,000 | 5% | 50 | 25 | 25 | 1,050 |
| 10,000 | 12% | 1,200 | 600 | 600 | 11,200 |
| 50,000 | 18% | 9,000 | 4,500 | 4,500 | 59,000 |
| 100,000 | 28% | 28,000 | 14,000 | 14,000 | 128,000 |
Frequently Asked Questions
What is GST?
GST (Goods and Services Tax) is a unified indirect tax levied on the supply of goods and services in India, replacing multiple older taxes like VAT, service tax, and excise duty.
What are the current GST slabs?
India has five main slabs: 0% (essential items), 5% (necessities), 12% (processed goods), 18% (most goods and services), and 28% (luxury and sin goods). Some precious metals use 3%.
What is the difference between CGST, SGST, and IGST?
CGST goes to the central government and SGST to the state government for intra-state sales (each half the total rate). IGST at the full rate applies to inter-state sales and is collected by the centre.
How do I remove GST from a total price?
Divide the total by (1 + rate/100). For example, 1,180 with 18% GST: 1,180 / 1.18 = 1,000 base price, and 180 is the GST amount.
Who needs to charge GST?
Businesses registered under GST must charge it on taxable supplies. Registration is mandatory above the turnover threshold (40 lakh for goods, 20 lakh for services in most states).
People Also Ask
How much is 18% GST on 10,000?
18% GST on 10,000 is 1,800, making the total 11,800. Split as 900 CGST and 900 SGST for intra-state sales.
How do I calculate GST inclusive price?
To find the base price from a GST-inclusive amount, divide by (1 + rate/100). For 5,900 at 18%: 5,900 / 1.18 = 5,000 base and 900 GST.
Is GST calculated on MRP?
GST is calculated on the transaction value (selling price), not the printed MRP. If a discount is given, GST applies on the discounted price.
