GST can be confusing when you are not sure whether a price already includes tax or not. Getting it wrong on an invoice can cause problems later.
There are two common situations. When you add GST, you start with a base price and add the tax on top. When you remove GST, you start with the final price and work backwards to find the base amount.
Our GST Calculator handles both cases. Enter the amount, pick the rate, and choose whether to add or remove GST.
Common rates in India are 5%, 12%, 18% and 28%. Always confirm the correct slab for your product or service before billing a customer.
