![]() ![]() We want the denominator to be fixed for all percentage calculations so that each month expense will divide by the same total. We will autofill the formula for other month expenses (till row 15). Or follow the below steps for fast calculation. Now, use the same formula with other month expenses to calculate the percentage. We will later change it into a percentage after calculating for all other months. Step 7: Hit the Enter key and see the contribution of January month expenses from year total (percentage of total).Ĭurrently, both resultant values are in decimal form rather than percent. Step 6: Now, use the following formula to find the percentage of total and see how it is different than the simple percentage. Step 5: Hit the Enter key and see the contribution of January month expenses from the month total. This formula is for simple percentage calculation. Step 4: For the January month, use the following formula in which the January amount is divided by the total. In the column C, we will store the result of percentage and in column D, we will store the result of percentage of total. Now, calculate the simple percentage and percentage of total for the first month. Step 2: Hit the Enter key and get the calculated sum, i.e., 31200. For this, write the formula to find the total sum of the given months in the B16 cell. Step 1: Firstly, we will calculate the total of all months. Before anything else, you need sum of expense (total expense) so that we can calculate the percentage of total. Here, we will calculate the percentage of expenses for each month. We have a list of travel expenses for a year (January to December) in column B. Example to calculate the percentage of total Fractions are converted to a percentage by multiplying them by 100%. People use the percentage calculation in their daily life. Percentage is calculated using the basic operation (multiply and division) of mathematic, we described above. Percentage is one of the essential formulas of mathematics that the Excel users may require to calculate the percentage on Excel data. ![]() So, after applying the percentage of total formula, i.e., =A3/B3, it returns 12% after applying the percentage format on the resultant value. The compound interest formula above can also be used for percentage decreases.In this formula, part of the work done is divided by the total work but not multiplied by 100.įor example, A month expense is 3000 (cell A3) and the total expense is 24800 (cell B3). It is predicted that their number will decrease by 12% each year. New value = 100 - percentage decrease × original valueĪt the end of 2003 there were 5000 members of a certain rare breed of animal remaining in the world. So if the £500 had been left in the bank for 9 years, the amount would have increased to: (100 + %change) no of years × original value ![]() The simple way to work out compound interest is to multiply the money that was put in the bank by n m, where n is (100 + percentage increase)/100 and m is the number of years the money is in the bank for, i.e: This phenomenon is known as compound interest. Every year, if the money is left sitting in the bank account, the amount of interest paid would increase each year. The interest, therefore, will be higher than the previous year (6% of £530 is more than 6% of £500). If in this example, the money was left in the bank for another year, the £530 would increase by 6%. In other words, the old value is £500 and it has been increased by 6%. Work out the amount in the bank after 1 year. £500 is put in a bank where there is 6% per annum interest. New value = 100 + percentage increase × original value It is the original value we wish to find, so the above formula is used. If the length is actually 17.6cm, what is the percentage error in Nicola's calculation?Īmish buys a stamp collection and makes a 35% profit by selling it for £2700. Nicola measures the length of her textbook as 20cm. By how much percent has the price increased by? The price of some apples is increased from 48p to 67p. % change = new value - original value × 100 ![]()
