What are the GST slabs in India?
India has 4 main GST slabs: 5% (essential goods), 12% (processed food, business services), 18% (most goods/services), and 28% (luxury items, sin goods).
How do I calculate GST?
To add GST: GST Amount = (Original × GST%) ÷ 100. Total = Original + GST Amount. To remove GST: Original = Total ÷ (1 + GST%/100).
