Interactive Discount & Sale Calculator

To find the discount percentage, use this formula: For example, if a $100 item is now $75, the discount is ((100 - 75) / 100) × 100 = 25% off.

Yes! Many retailers allow stacking a coupon code on top of a sale price. However, the order matters:

• Sequential (Recommended): Apply the sale discount first, then the coupon on the reduced price. This gives the retailer a smaller base to discount from.
• Not additive: A 20% sale + 10% coupon is NOT the same as 30% off. The correct calculation is: 100 × 0.80 × 0.90 = $72 (28% total savings, not 30%).

This calculator uses sequential discounting, which is how most retailers apply multiple promotions.

In most countries (including the US and India), tax is calculated on the discounted price, not the original price. This is good news — you pay tax on the lower amount.

For example, if a $100 item is discounted to $75 and tax is 10%, you pay $75 + $7.50 tax = $82.50 total. You save both on the discount AND on the reduced tax amount.

This calculator applies tax after all discounts, which reflects real-world retail practice.

Major discount events throughout the year:

• Black Friday / Cyber Monday (November): 30-70% off across most categories
• End of Season Sales: 40-60% off on clothing and seasonal items
• Amazon Prime Day (July): 20-50% off on electronics and appliances
• Clearance Events: 50-80% off on discontinued or last-season items
• Holiday Weekends: Memorial Day, Labor Day — 20-40% off on furniture and mattresses

Not always. A 50% discount on an overpriced item might cost more than a 20% discount on a fairly priced one. Always compare:

• Price across retailers: Check if the "discounted" price is actually competitive
• Historical prices: Some sellers inflate MRP before showing huge "discounts"
• Total cost including tax: A lower sticker price with high tax might exceed a higher price with no tax
• Quality and need: The best deal on something you don't need is still money wasted
