FAQ
What is the difference between exclusive and inclusive GST?
Exclusive means the amount is before tax, so the calculator adds GST to get the price with tax. Inclusive means GST is already inside the amount, so it backs out the base value and the tax portion.
Which GST slabs does this support?
You can choose the common Indian rates of 5%, 12%, 18%, or 28%. Pick the slab that matches the goods or services you are pricing, and confirm current rules when they change.
Is this an official GST filing figure?
No. It is a quick estimate for quotes and checks. GST rules and classifications can change, so verify rates and invoicing with a tax professional or the GST portal before filing.
Is my data private?
Yes. Invoice amounts and rates stay in this browser tab. Nothing is uploaded to compute GST.
