Common Percentage Calculations
Percentages are essential in everyday life. Whether you're calculating a tip at a restaurant, finding out if a sale price is worth it, or analyzing year-over-year business growth, the math remains the same. Percentage literally means "per one hundred."
How to Calculate Percentage Manually
To find a percentage of a number, multiply the number by the percentage and then divide by 100. For example, to find 15% of 200: (15 × 200) / 100 = 30.
- Sales Tax: Find out exactly how much tax is added to your purchase.
- Discounts: Subtract the percentage value from the original price to find the deal.
- Interest Rates: Compare APY or APR across different banks to find the best savings.
Calculating Percent Change
To find the percentage increase or decrease between two values, take the difference between the two numbers, divide that difference by the original value, and then multiply by 100. A positive result is an increase, a negative result is a decrease.
