How to calculate GST Calculator
Step-by-step Guide & Informational Intent
- 1.Enter the 'Base Amount' of the product or service.
- 2.Select the applicable 'GST Rate' from the standard slabs.
- 3.Choose whether you want to Add GST to the base or Remove GST from a total price.
- 4.View the instant results showing the tax amount and total gross price.
- 5.Copy the breakdown for your invoices or accounting records.
How the Calculation Works
For adding GST, we use: Total = Base + (Base * Rate/100). For removing GST (Reverse), we use: Base = Total / (1 + Rate/100). The tax is then split 50/50 between CGST and SGST for local sales.
Important Assumptions
- • Current Indian GST slabs are applied
- • CGST + SGST split is default for intra-state
- • IGST is equal to the full tax rate for inter-state
- • Rounding is done to the nearest paise

| 12% Standard | ₹6,000 | ₹6,000 | ₹12,000 |

As a small business owner, the reverse GST feature is a lifesaver. The calculations are 100% accurate and match my Tally entries perfectly.
