How to calculate discount
With shopping seasons and sales popping up all year round, understanding how to calculate discounts is a valuable skill. In this article, we’ll walk you through the basics of calculating various types of discounts to help you save money and make informed decisions when shopping.
Step 1: Understand the Different Types of Discounts
Before calculating a discount, it’s crucial to know the various types of discounts available. Some common types include:
1. Percentage discount: A percentage reduction in an item’s original price.
2. Fixed amount discount: A specific amount subtracted from an item’s original price.
3. Buy X Get Y free/discounted: Purchase a certain quantity of items, and receive another item either for free or at a discounted rate.
Step 2: Percentage Discounts
To calculate a percentage discount, follow these steps:
1. Convert the percentage discount into a decimal by dividing it by 100.
Example: A 20% discount would be 20 ÷ 100 = 0.2
2. Multiply the decimal by the original price of the item.
Example for a $50 item with a 20% discount: 0.2 (the decimal) × $50 (the original price) = $10 (the discount amount)
3. Subtract the discount amount from the original price.
Example: $50 (original price) – $10 (discount amount) = $40 (discounted price)
Step 3: Fixed Amount Discounts
Calculating fixed amount discounts is relatively straightforward.
1. Subtract the fixed discount amount from the original price.
Example for a $50 item with a $15 discount: $50 (original price) – $15 (discount amount) = $35 (discounted price)
Step 4: Buy X Get Y Free/Discounted Deals
For these deals, perform the following steps:
1. Calculate the total cost without the offer by multiplying the per-item price by the number of items required.
Example for a Buy 2 Get 1 Free deal, with each item at $25: 3 (total items) × $25 (per-item price) = $75 (total cost without offer)
2. If the offer is “get Y free,” subtract the cost of Y free items.
Example: $75 (total cost without offer) – $25 (cost of one free item) = $50 (total cost with offer)
3. If the offer is “get Y discounted,” calculate the discounted price for Y items and subtract this amount from the total cost without offer.
Example for a Buy 2, Get 50% Off the 3rd Item deal:
a. Calculate discount on the third item: 0.5 (decimal value of 50%) × $25 (original price of one item) = $12.50
b. Subtract discount from total cost without offer: $75 – $12.50 = $62.50 (total cost with offer)
Conclusion:
Calculating discounts can be simple once you understand the steps involved for different types of discounts. With this knowledge in hand, you’ll be able to make smarter shopping choices and maximize your savings. Happy shopping!
