## How to Calculate Percentage Increase on a Price

If you are looking to calculate the percentage increase on a price, then you have come to the right place. This article will walk you through the steps of calculating the percentage increase on a price using various methods. By the end of this article, you will be able to calculate percentage increases with ease.

### Determine the original price

The first step in calculating the percentage increase on a price is to determine the original price. This is the price of the item or service before any increase has been applied. For example, if an item originally cost \$50, then the original price is \$50.

### Determine the new price

The next step is to determine the new price. This is the price of the item or service after the increase has been applied. For example, if the item now costs \$70, then the new price is \$70.

### Calculate the difference

Once you have the original price and the new price, you need to calculate the difference between the two. To do this, subtract the original price from the new price. For example, \$70 - \$50 = \$20.

### Divide the difference by the original price

To calculate the percentage increase, you need to divide the difference by the original price. This will give you the percentage increase as a decimal. For example, \$20 ÷ \$50 = 0.4.

### Convert decimal to percentage

To convert the decimal to a percentage, multiply it by 100. For example, 0.4 × 100 = 40%. This means that the price has increased by 40%.

### Using a formula

Another way to calculate the percentage increase is to use a formula. The formula is: ((new price - original price) ÷ original price) × 100. Using the example above, the formula would be: ((\$70 - \$50) ÷ \$50) × 100 = 40%.

### Examples of percentage increase

Let’s look at some other examples of how to calculate percentage increase.

Example 1: Original price = \$100, New price = \$125

Step 1: \$100

Step 2: \$125

Step 3: \$125 - \$100 = \$25

Step 4: \$25 ÷ \$100 = 0.25

Step 5: 0.25 × 100 = 25%.

Therefore, the price has increased by 25%.

Example 2: Original price = \$75, New price = \$90

Step 1: \$75

Step 2: \$90

Step 3: \$90 - \$75 = \$15

Step 4: \$15 ÷ \$75 = 0.2

Step 5: 0.2 × 100 = 20%.

Therefore, the price has increased by 20%.

### Calculating percentage decrease

You can also use the same formula to calculate percentage decrease. The only difference is that you will be subtracting the new price from the original price. For example, if the original price was \$100 and the new price is \$75, you would follow these steps:

Step 1: \$100

Step 2: \$75

Step 3: \$75 - \$100 = -\$25

Step 4: -\$25 ÷ \$100 = -0.25

Step 5: -0.25 × 100 = -25%.

Therefore, the price has decreased by 25%.

### Using a calculator

If you don’t want to calculate the percentage increase manually, you can use a calculator. Most calculators have a percentage function that allows you to input the original price and the new price and it will calculate the percentage increase for you. Simply enter the original price, press the percentage key, enter the new price, and press equals. The calculator will display the percentage increase.

### Why calculate percentage increase

Knowing how to calculate percentage increase is useful in many situations. For example, if you are running a business and you want to increase your prices, you need to know by how much to increase them. If you are negotiating a raise or a new salary, you need to know how much of an increase you are getting. If you are shopping for a new car or a house, you want to know how much the price has increased or decreased over time.

### Factors that affect price increase

There are several factors that can affect the percentage increase of a price. One factor is inflation. Inflation is the rate at which the general level of prices for goods and services is rising, and, subsequently, purchasing power is falling. Another factor is supply and demand. If demand for a product is high and supply is low, the price will increase. Conversely, if demand for a product is low and supply is high, the price will decrease. Competition also plays a role in price increase. If there are many competitors in a market, prices will likely stay the same or decrease. However, if there are only a few competitors, prices may increase.

### Negotiating price increase

If you are trying to negotiate a price increase, there are several things you can do to increase your chances of success. First, research the market and find out what the going rate is for the product or service you are trying to purchase. This will give you an idea of what a fair price is. Next, be prepared to walk away if you can’t get the price you want. Sometimes, the threat of losing a sale is enough to get the seller to lower the price. Finally, be polite and respectful when negotiating. If you are aggressive or rude, the seller may be less likely to work with you.

### Conclusion

Calculating percentage increase is a useful skill to have in many situations. By following the steps outlined above, you can easily calculate the percentage increase on a price. Whether you are running a business, negotiating a salary, or shopping for a new car, knowing how to calculate percentage increase will help you make informed decisions. Remember, always do your research and be prepared to negotiate to get the best price.
