How to Remove 18% GST from Total Amount

Quick Formula

GST Amount = Total Amount - Amount without GST

Step-by-Step Method

1

Take your total amount (which includes 18% GST)

2

Divide by 1.18 (since 1 + 18/100 = 1.18)

3

The result is your amount without GST

4

Subtract to find GST amount (Total - Without GST = GST)

Real Examples

Example 1: ₹50,000

Total Amount: ₹50,000

Amount without GST: ₹50,000 ÷ 1.18 = ₹42,373

18% GST Amount: ₹50,000 - ₹42,373 = ₹7,627

Example 2: ₹1,00,000

Total Amount: ₹1,00,000

Amount without GST: ₹1,00,000 ÷ 1.18 = ₹84,746

18% GST Amount: ₹1,00,000 - ₹84,746 = ₹15,254

Example 3: ₹1,180

Total Amount: ₹1,180

Amount without GST: ₹1,180 ÷ 1.18 = ₹1,000

18% GST Amount: ₹1,180 - ₹1,000 = ₹180

Example 4: ₹11,800

Total Amount: ₹11,800

Amount without GST: ₹11,800 ÷ 1.18 = ₹10,000

18% GST Amount: ₹11,800 - ₹10,000 = ₹1,800
