The Four Pillars of GST Slabs
In India, products and services are categorized into four primary slabs. Essential items are taxed at 5%, while standard manufactured goods usually fall into the 12% or 18% categories. Luxury items, including automobiles and sin goods, attract the highest rate of 28%. By selecting the correct rate in our tool, you ensure that your retail pricing remains competitive and legally sound.
The Formula Behind the Calculation
While our tool handles the heavy lifting, professional accountants often use these manual formulas for cross-verification:
- GST Addition: (Amount × GST Rate) / 100.
- GST Removal (Inclusive Price): Amount − (Amount × (100 / (100 + GST Rate))).
