Percent Off Calculator: Find Discounted Price with Single or Stacked Offers

How do you figure out percentage off?

Taking a percentage off a price means calculating a discount by reducing the original price by a certain percentage. To do this, follow these steps:

1. Determine the percentage you want to discount (e.g., 20%).
2. Convert the percentage to a decimal by dividing it by 100 (20% becomes 0.20).
3. Multiply the original price by the decimal to find the discount amount.
   • Example: For a $180 total with a 20% discount, multiply $180 × 0.20 = $36.
4. Subtract the discount amount from the original price to get the final price.
   • Example: $180 - $36 = $144.

This process works for any percentage and helps you calculate the reduced price after applying the discount.

How does percentage off stack with other discounts?

When stacking multiple discounts, it’s important to understand how they work together. For instance, if an item is 15% off and you can stack another 10% discount, the total discount is not a straight 25%. Instead, the second discount is applied to the already-reduced price, not the original price.

For example, if you apply a 20% discount to an item, reducing its price to $144, and then stack an additional 10% discount, you calculate the second discount on $144. Multiply $144 by 0.10 to get $14.40. Subtracting this from $144 brings the final price to $129.60.

This stacked discount is less than a single 30% discount would be, illustrating how stacking works incrementally.

Does the order of discounts matter?

If you're stacking 'percent off' discounts, the order in which you use them will not matter. This because calculating the discount is all based on multiplication. The order in which you multiply these numbers will not change the outcome.

For example, let's say that you have a 10% coupon and a 25% coupon that can be stacked together on a order that costs $200.

The final price ends up being the same because both discounts only involved multiplication.
