Percent Change in Everyday Life
Percent change is used to track stock performance, calculate inflation impact, compare year-over-year revenue, and evaluate test score improvements. A stock that goes from $100 to $85 fell by 15%. A price rising from $20 to $23 is a 15% increase.
VAT and Tax Calculations
To add VAT (e.g., 20% UK VAT): multiply price by 1.20. To remove VAT from a VAT-inclusive price: divide by 1.20. Korean VAT is 10%, so divide a 부가세 포함 price by 1.10 to get the pre-tax price.
