Frequently Asked Questions
How do I calculate a 20% discount?
Multiply the original price by 0.20 to get the discount amount, then subtract from the original price. For example, 20% off $100 = $20 discount, sale price = $80.
What is the difference between discount and markup?
A discount reduces the price from the original. A markup increases the price above the cost. Discount is customer-facing; markup is business-facing.
Can I stack multiple discounts?
Yes, but be careful. A 20% discount followed by a 10% discount is NOT 30% off. It is 20% off, then 10% off the reduced price. Use the reverse calculator to find the original price after stacked discounts.
