If you have any problems using the percentage calculator tool, please contact me. It's worth noting that we have an article dedicated to how to calculate percentages here. In equation form, where Z is your answer, your equation is Z = X / (Y/100).Next, we divide our X figure by our Y figure.We do this by dividing the figure by 100. Step one is to change the Y percentage figure into a decimal.Percentage Formula: A B P × 100 Where, P Percentage A First value B Second Value From this formula, we can make many variations. Let's say the question is: 5 is 20% of what number? How to Calculate Percentages There are many formulas and solutions to find the percentage manually. Let's replace the X and Y with a couple of figures. In equation form, where Z is your answer, your equation is Z = (Y-X) / X * 100.The percentage increase from 40 to 68 = 70%. As this is a decimal, we convert it into a percentage figure by multiplying it by 100. Note that we've put brackets around the first part to ensure this is done first (see our article on PEMDAS and the order of operations for explanation). In the case of our example it would be (68-40) / 40. Our first step is to subtract X from Y and then divide it by X.Or we can work the calculation out manually. However, if solving for the percentage, the value returned will be the actual percentage, not its decimal representation. We can use the percentage change calculator. The calculator provided automatically converts the input percentage into a decimal to compute the solution. In percentage calculator You can input integer (3), decimal (2.4), fraction (5/7) or mixed fraction (2 1/7). Click the Calculate button and an actual value will be displayed, in this case 0.4. On the second input field, add the base value where you want to take the percentage from. Let's say the question is: What is the percentage increase from 40 to 68? In the first input field, enter a percentage (base from example above, enter 4). In equation form, where Z is your answer, your equation is Z = (X/Y) * 100.Īdvertisement What is the percentage increase or decrease?Ĭontinuing the theme, let's replace the X and Y with a couple of figures.To convert this into a percentage figure we need to multiply by 100. Step 1 has given you a decimal figure.So, in the case of our example: 15/300 = 0.05. Our first step is to divide the X figure by the Y figure.Let's say the question is: 15 is what percent of 300? You may also find the percentage calculator is also useful in this type of problem.Once again, we'll replace the X and Y with a couple of figures to explain this. It can even be used to solve more complex problems that involve percent increase. The percentage growth calculator is a great tool to check simple problems.
