GST kaise nikalta hai?

Exclusive me GST = amount × rate ÷ 100. Inclusive me base price = amount × 100 ÷ (100 + rate), aur GST = amount − base. Invoicing ke liye sahi slab apne CA se confirm kar lein.

How to Use

Enter the amount.
Select the GST rate (5/18/40% or custom).
Choose inclusive (remove GST) or exclusive (add GST).
See the breakup: base price + GST = total.

Formula

Add GST: Total = Amount × (1 + rate/100). Remove GST: Base = Total ÷ (1 + rate/100); GST = Total − Base.

💡 Example

Example: ₹1,000 + 18% GST → total ₹1,180. A ₹1,180 GST-inclusive bill at 18% → base ₹1,000, GST ₹180.
