### What is a Percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using an improper fraction with a numerator of 100 and denominator of some whole number (for example, 25% equals 1/4). In finance, it is also known as a rate or a percent yield. The per cent sign ( %) was introduced in 1637 by John Napier in his book Descriptio. In accounting and business, there are two different meanings: nominal value which is explicit amount; real value for calculations. They are both types of measurement used to compare scales and magnitudes within numbers. It looks good on paper but does not mean anything when analyzing your actual profit and loss situation...

### How do you Calculate Percentages?

Calculating percentages can be somewhat tricky, but as long as you follow a few simple rules you'll be well on your way to getting an accurate percentage in no time. To begin calculating a percentage, simply divide a number by 100 and use that number when referencing that amount. For example, if you wanted to know what 50% of 800 is, you would take 800 (the amount) and divide it by 100 (100%). The answer is 400.

### What are some Example Uses of the Percentage Calculator?

The percentage calculator is a handy tool for checking if you’re getting good deals, or are being charged too much. For example, did you know that grocery stores aren’t legally allowed to charge more than one-eighth of a cent per item as a price markup? In other words, if your item costs $1.00 and has seven items in it, they can only legally charge you $0.14 more than what they paid for it; everything else is pure profit. Using our calculator, we can see that 7 items in 1 item equates to 21.42% of the total cost; not ideal!

### Why is it Important to Know How to Calculate Percentages?

Percentages are often used in day-to-day conversations. When you hear about the increase in prices of a good or read that the economy grew by 0.5%, you are actually hearing about percent increases and decreases, respectively. Knowing how to calculate percentages is therefore crucial for any professional setting.

### When Would You Use the Percentage Calculator Online?

The percentage calculator is a tool you’ll use in a variety of situations to help determine exactly how much of one thing is in relation to another. In school, you’ll need it to calculate percentages on quizzes and tests. If you want to lose weight or run your own business, you’ll need it to determine how much of a particular ingredient or commodity (eggs, sugar, wheat) goes into a larger recipe or product.
