Here I will show 3 methods to calculate the percentage change of negative numbers in Excel but all of them will mislead you. Whatever methods you use, you will find misleading results. When it is not possible theoretically, how can we calculate them in Excel? Theoretically and even practically, you cannot find the percentage change for negative numbers. Then we have multiplied the absolute value by 2 and then divided the value by (A2+B2)Ĭalculate Percentage Change for negative numbers in Excel.So, we have used the ABS() function ( ABS(A2-B2)) to make the number absolute.
The difference between numbers A2 and B2 ( A2-B2) can be negative.We have used this formula in the cell C2: =2*ABS(A2-B2)/(A2+B2) In Excel, we can easily calculate the Percent Difference: Note: Percentage Change ((New value/Old value) -1) and Percent Difference are two different phenomena in Physics.
Here, E 1 = First experimental value and E 2 = Second experimental value This is the equation to calculate the Percent Difference. In Percent Difference, you will compare two experimental values. Percent Difference and Percent Error are actually the same things. The percentage difference between the two numbers in Excel You see that the previous negative differences are now showing as positive numbers (without any sign). We have used the ABS() Function in the same data. To get the absolute difference between two numbers in Excel, we shall use the ABS() Excel function.ĪBS() function returns the absolute value of a number, a number without its sign. We get the same result but we did write just one Excel formula and applied it to other cells.ģ) Calculate the absolute difference between two numbers in Excel (Using ABS() function) You can apply the same formula to multiple cells in Excel in more than one way. Now copy this formula for other cells in the column.Press Enter and this is the result we get.
In the cell C2, input this formula: =A2-B2.So, we shall use this method and this is why Excel is so useful. We can make a formula for a single set of numbers and then use the formula for other cells. Time-consuming as you have to write a formula for every set of numbers individuallyĢ) Using cell references instead of numbers in the formula.You cannot copy the same formula for another set of numbers.If you have more than one subtraction, you have to write a formula for every subtraction individually.Note: If the subtrahend value is negative, use the parentheses to place the number in the subtraction formula like this: =-91-(-23) So, input an equal sign (=) to start an Excel formula > Input the minuend value > Input the minus sign (-) > Place the subtrahend value > Press Enter You know, every formula starts with an equal sign in Excel In this way, we input the numbers directly in the formula. Instead, we use the regular minus (-) symbol to perform subtractions. In MS Excel, you will not find any SUBTRACT function to perform the subtraction operation.

How to find the difference between two numbers in Excel using Formula This is more explicit in referencing the correct sheet, because you're using a Range parameter in place of numeric arguments: Function CellColour(r As Range) As LongĬellColour = r.Cells(1).Interior.ColorIndexĮDIT: This might be more what you need: Function SumB圜olour(r As Range, indx As Long) As Long

This might explain why your "grey" cells give -4142, which is actually the code for "no fill" (xlNone) here the Cells() will always apply to the ActiveSheet, which may or may not be the one you expect/want. That aside, your function has a problem: Function CellColour(Irow As Integer, Icol As Integer) As LongĬellColour = Cells(Irow, Icol).Interior.ColorIndex Using a cell color to encode information is not a great approach: you'd be much better off with a "Status" column (which could then drive conditional formatting to add the color, but also can be more-easily used in other formulas)
