what is Percentage Calculator
A percentage calculator is a tool that helps you calculate the percentage of a number or find the percentage increase or decrease between two numbers. For example, if you want to calculate what percentage of 50 is 10, or how much a number has increased or decreased by a certain percentage, you can use a percentage calculator to quickly get the answer. This tool can be useful in a variety of situations, such as calculating discounts or sales prices, figuring out the percentage of a test score, or analyzing financial data. There are many online percentage calculators available for free, as well as calculators built into many spreadsheet and calculator programs.
what is Percentage Calculator formula
The formula for calculating percentages depends on what you are trying to find. Here are some common formulas:
To find the percentage of a number:
percentage = (part / whole) x 100
For example, if you want to find what percentage of 50 is 10, the calculation would be:
percentage = (10 / 50) x 100 = 20%
To find the part given the whole and the percentage:
part = (percentage / 100) x whole
For example, if you want to find what 20% of 50 is, the calculation would be:
part = (20 / 100) x 50 = 10
To find the whole given the part and the percentage:
whole = part / (percentage / 100)
For example, if you want to find what is the total cost when you know that 20% of it is 10, the calculation would be:
whole = 10 / (20 / 100) = 50
To find the percentage increase or decrease:
percentage change = ((new value - old value) / old value) x 100
For example, if you want to find the percentage increase from 50 to 75, the calculation would be:
percentage change = ((75 - 50) / 50) x 100 = 50%
To find the new value after a percentage increase or decrease:
new value = old value ± (percentage / 100) x old value
For example, if you want to find the new value after a 25% increase from 100, the calculation would be:
new value = 100 + (25 / 100) x 100 = 125
Alternatively, if you want to find the new value after a 15% decrease from 200, the calculation would be:
new value = 200 - (15 / 100) x 200 = 170
To find the percentage difference between two numbers:
percentage difference = ((new value - old value) / ((new value + old value) / 2)) x 100
For example, if you want to find the percentage difference between 75 and 100, the calculation would be:
percentage difference = ((100 - 75) / ((100 + 75) / 2)) x 100 = 16.67%
These formulas can be useful in many different situations where you need to calculate percentages, such as when working with financial data, analyzing test scores, or figuring out the price of a sale or discount.
