📊 What is the GST Profit Margin Calculator and How Does It Work?
For GST-registered businesses with full ITC, GST is largely cost-neutral. But for composition dealers, B2C businesses, and end-consumers, GST is a real cost that must be carefully factored into profit margin calculations.
FormulaRequired base = Cost ÷ (1 – margin%) | Selling price with GST = Base × (1 + GST rate/100)
