Frequently Asked Questions
How do I add GST to a base amount?
Choose the mode for tax on top of price (exclusive). Enter the base amount and GST rate (e.g. 5%, 12%, 18%). You get GST amount and total payable.
How do I remove GST from a total (inclusive price)?
Use inclusive mode when the amount you typed already includes GST. The tool splits out base value and tax so you can match invoice line items.
What is the difference between inclusive and exclusive GST?
Exclusive: price before tax, GST is added. Inclusive: price already contains tax; you back out base and GST. Pick the mode that matches how your amount was quoted.
Which GST rates can I use?
Enter any percentage your scenario needs (common slabs in India include 5%, 12%, 18%, and 28%). The math is generic for any rate you set.
Can I use this for invoices and quotes?
Yes, for quick splits and checks. Always confirm statutory wording, rounding rules, and place of supply with your accountant or billing system for official documents.
