Discount calculations come up in purchasing decisions, sales quoting, invoice review, and retail shopping — and doing them mentally or on a phone calculator is error-prone. The Utility Spark Discount Calculator handles the three most common discount scenarios: (1) Calculate the final price after a percentage discount (₹2,400 at 15% off = ?), (2) Calculate the amount saved from a discount (what is 15% of ₹2,400?), and (3) Find the original price from a known discounted price and discount rate (I paid ₹1,800 after 25% off — what was the original price?). Works for both percentage discounts and flat-amount discounts.

Original price: ₹5,000 | Formula: 4,500 ÷ (1 - 0.10) = ₹5,000

Frequently Asked Questions

Is a 20% + 10% stacked discount the same as 30% off? expand_more
No. Stacked discounts are not additive. A 20% discount followed by 10% discount: ₹1,000 × 0.80 = ₹800, then ₹800 × 0.90 = ₹720. Total effective discount = 28% (not 30%). The combined formula is: (1 - d1) × (1 - d2) = (1 - 0.20) × (1 - 0.10) = 0.72, so effective discount = 28%.
How do I calculate what percentage discount I received? expand_more
Discount % = (Original price - Sale price) ÷ Original price × 100. Example: Original ₹800, Sale ₹600 → Discount = (800-600) ÷ 800 × 100 = 25%. If you only know the sale price and discount %, the original price is: Original = Sale price ÷ (1 - discount %).
