Understanding GST Calculation
Adding GST (Exclusive)
Used when you want to create a bill. You have the product price (e.g., ₹1000) and need to add 18% tax on top of it.
Formula: Amount + (Amount × 0.18)
Removing GST (Inclusive)
Used when you have a total bill (e.g., MRP ₹1180) and want to know the actual product price and how much tax was included.
Formula: Amount / 1.18
