The Truth About Stacked / Double Discounts
Retail banners often promote sales with terms like "50% Off + Extra 20% Off at Checkout". Shoppers often assume this equals a 70% total cut, but retail POS systems calculate discounts sequentially:
- Original Price: ₹1,000
- First 50% discount reduces price to: ₹500
- Second 20% discount is applied to the new subtotal (₹500 × 0.20 = ₹100 discount)
- Final Price Paid: ₹400 (An effective 60% discount, not 70%)
Markup vs. Profit Margin: What's the Difference?
Business owners frequently confuse markup and margin, leading to mispriced goods and lost revenue:
Markup is the percentage by which the cost price is increased to reach the selling price: Markup % = (Profit / Cost) × 100
Gross Profit Margin is the percentage of total sales revenue that remains after deducting cost of goods sold: Margin % = (Profit / Selling Price) × 100
A 100% markup on a ₹50 cost produces a ₹100 price, which is a 50% margin.
Frequently Asked Questions (FAQ)
How do you calculate discount percentage?▾
Multiply the base price by the discount rate divided by 100 to get the saved amount. Subtract the savings from the base price to find the final payable price.
How does our calculator handle sales taxes on discounted items?▾
When you add taxes (such as GST or local sales tax) using the "+ Add Tax" feature, the tax percentage is automatically computed on the discounted subtotal, complying with international billing conventions.
Can I use this tool to calculate markup or service fees?▾
Yes. Toggle to "Add % (Markup / Margin / Fee)" mode. The percentage will be added to your base amount rather than subtracted, showing your total markup amount and final selling price.
How do I calculate what percentage discount was given?▾
To find the discount percentage: Discount % = ((Original Price - Sale Price) / Original Price) × 100. For instance, if an item dropped from ₹2,000 to ₹1,500: ((2000 - 1500) / 2000) × 100 = 25% discount.
