📋 How to Use This Calculator

Results show both the rupee saving and percentage saving for quick comparison.
💡 Key Facts & Information
Common discount formats in Indian retail: "Flat 40% off" (straightforward percentage), "Buy 2 get 1 free" (effective 33.3% discount), "MRP ₹999, Sale ₹599" (40% discount), "Extra 10% off with coupon" (stacks on already-discounted price). Stacked discounts: 20% off then additional 10% off is NOT 30% off — it is 28% off. Formula: final = original × (1−0.20) × (1−0.10) = original × 0.72. GST interaction: discounts on MRP reduce the taxable value — a ₹1,000 product with 18% GST discounted by 20% is taxed on ₹800, not ₹1,000. For business purchases, trade discounts reduce the invoice value before GST is applied.
