Real World Percentage Uses
Percentages are everywhere in daily life. Mastering them can save you money and help you make better decisions.
Tipping & Discounts
To calculate a 20% tip, move the decimal point one place to the left (10%) and double it.
Example: $50 bill -> $5.00 (10%) -> $10.00 (20%).
Finance & Taxes
Sales tax is a percentage increase. If tax is 8%, multiply the price by 1.08 to get the final total.
Percentage Change vs. Difference
- Percentage Change: Used when a value changes over time (e.g., Stock price went from $100 to $110 = 10% increase).
- Percentage Difference: Used when comparing two separate things (e.g., Apple A costs $100, Apple B costs $110. They have a ~9.5% difference).
Frequently Asked Questions
How do I reverse a percentage?
To find the original price before a sale (e.g., 20% off), divide the final price by 0.80 (100% - 20%). Example: If a shirt is $80 after a 20% discount, original price was $80 / 0.80 = $100.
How to calculate percentage increase in Excel?
In Excel, use the formula: =(New_Value - Old_Value) / Old_Value. Then click the "%" button to format it as a percentage.
What is 1 basis point?
In finance, a basis point (bps) is 1/100th of 1%. So 100 bps = 1%. If interest rates rise by 50 bps, they rose by 0.50%.
How to convert fraction to percentage?
Divide the top number (numerator) by the bottom number (denominator) and multiply by 100. Example: 3/4 = 0.75 * 100 = 75%.
