FAQs

What's the difference between % increase and % of?
"% of" is a simple ratio. "% increase" compares the change to the original: an increase from 50 to 75 is a 50% increase, but 75 is 150% of 50.
How do I calculate 20% off?
Multiply the price by 0.80 (100% − 20%) to get the final price, or by 0.20 to get the discount itself.
