Discount Calculator

Calculate sale price after discount, amount saved, and compare double discounts. Find the real deal during sales. Free online discount calculator.

What is Discount Calculator?

The Discount Calculator computes the final price after applying a percentage discount. It also handles stacked discounts (e.g. 20% + 10% additional) and shows you the effective total discount and actual savings.

How to Calculate Discount

  1. Enter the original price (MRP)
  2. Enter the discount percentage
  3. Click Calculate to see sale price, amount saved, and effective discount

How Discount Calculator is Calculated

Sale Price = Original Price × (1 − Discount% / 100). For stacked discounts: Final Price = Original × (1 − D1/100) × (1 − D2/100). Effective discount is NOT D1 + D2.

Worked Example

Original price ₹2,000, discount 25%: Sale price = ₹2,000 × 0.75 = ₹1,500. Savings = ₹500. With additional 10%: ₹1,500 × 0.90 = ₹1,350. Effective discount = 32.5%, not 35%.

Common Use Cases

  • Shopping sale price calculation
  • Comparing discount offers
  • Business pricing and margin assessment
  • E-commerce deal comparison

Common Mistakes to Avoid

  • Adding stacked discounts directly — "20% + 10% off" is NOT 30% off. It is 20% first, then 10% on the reduced price = 28% effective discount.
  • Not checking if discount is on MRP or selling price — some retailers inflate the MRP to show a larger discount. Compare with other stores.
  • Ignoring GST after discount — GST is applied on the discounted price, not the original MRP.
  • Assuming bigger percentage discount always means bigger savings — 50% off on a ₹500 item saves less than 20% off on a ₹5,000 item.

Frequently Asked Questions

How do I calculate what I save?

Savings = Original Price × Discount% / 100. For ₹3,000 at 30% off: savings = ₹900, sale price = ₹2,100.

What is the effective discount of 20% + 10%?

The effective discount is 28%, not 30%. First 20% reduces ₹100 to ₹80, then 10% of ₹80 = ₹8 off, final = ₹72.

Why Use This Calculator?

E-commerce sales in India (₹7+ lakh crore in 2025) make discount calculation essential for smart shopping. Understanding the difference between flat discounts, successive discounts, and buy-one-get-one is key. A "50% + 20% off" deal is NOT 70% off — it's actually 60% off. This calculator reveals the real savings.

What This Tool Offers

  • Successive discount calculator
  • Compare discount offers

Calculation Method

Discount Amount = Original Price × (Discount% / 100). Sale Price = Original – Discount. Successive: Final = Original × (1 – d1/100) × (1 – d2/100).

Worked Example

MRP ₹2,000 with 30% + 10% off: After 30%: ₹2,000 × 0.7 = ₹1,400. After 10%: ₹1,400 × 0.9 = ₹1,260. Effective discount: 37%, not 40%.

Expert Tips

  • 💡 Successive discounts: 30% + 20% = 1 – (0.7 × 0.8) = 44% total, not 50%.
  • 💡 BOGO (Buy 1 Get 1) is effectively a 50% discount on 2 items.
  • 💡 Always check the MRP — some sellers inflate MRP before showing "discounts."
  • 💡 Compare price per unit/gram for packaged goods — bigger isn't always cheaper.
  • 💡 Festival sales often have the best genuine discounts — track price history.
