Discount Calculator

**Discount Calculator — Find the Best Deal Instantly**

Whether you're shopping in a sale, negotiating a trade discount, or calculating markdown pricing for your store, our Discount Calculator helps you work out savings and final prices instantly.

**Two Calculation Modes**

**Mode 1: Apply Discount Percentage**
Know the original price and discount % → find the sale price and savings.
Formula: Savings = Original Price × (Discount% / 100)
Sale Price = Original Price – Savings

**Mode 2: Calculate Discount Percentage**
Know the original and sale price → find what percentage discount was applied.
Formula: Discount% = ((Original Price – Sale Price) / Original Price) × 100

**Retail and E-commerce Use Cases**

*Flash sales* — Quickly verify if a "50% off" claim is accurate by entering the original and sale price.

*Coupon codes* — Calculate whether stacking coupons (e.g., 20% off + an extra 10% off) gives the same result as a single 30% discount. Spoiler: it doesn't! 20% off ₹1,000 = ₹800, then 10% off ₹800 = ₹720 — that's 28% total, not 30%.

*Trade discounts* — Businesses receiving trade discounts from suppliers can instantly calculate invoice prices.

*Negotiation* — Know exactly what a 15% negotiated discount saves you before entering a negotiation.

**Multiple Discount Stacking**

When multiple discounts apply sequentially (not simultaneously), they cannot simply be added. Our calculator handles successive discount chains:

Original × (1 – d1/100) × (1 – d2/100) × ...

This is always less than the sum of the individual discounts.

**For Retailers: Margin vs. Markup**

- **Markup** is the percentage added to the cost price: Selling Price = Cost × (1 + Markup/100)
- **Margin** is the percentage of the selling price that is profit: Margin = Profit / Selling Price × 100

A 25% markup is NOT the same as a 25% margin. Our calculator handles both.
