Add Number to Multiple Cells in Excel

If you’ve already entered a number in a cell, or a group of cells, what’s a quick way to add something to that amount?

For example, I keep track of my To Do list in a workbook, and one of my items is “Daily Admin tasks”. Sometimes, I start the day by answering client emails, posting links to my latest blog post, and doing the accounting for the previous day’s sales.

So, I enter the time spent – 0.75 hours – and move on to the next task.


Later in the day, I might spend another 45 minutes on Admin tasks, so I want to add that to the previous amount, in cell D5.

If it’s late in the day, it might be difficult to add 0.75 + 0.75 in my head (or early in the day, if I haven’t had my coffee yet!)

Use Paste Special

One way to do this, and avoid basic mistakes in arithmetic, is to use Paste Special – Add.

  • Type the number in a cell, and copy that cell.
  • Then, use Paste Special – Add, to paste that amount into another cell.


That technique works well, but it takes a few steps – and that adds more time to my Admin tasks!

Use a Macro to Add Amounts

To make the job easier, I created a couple of macros that add numbers to selected cells. There is a link to the download page, at the end of this article.

  • Macro 1 adds a set number to the selected cells.
  • Macro 2 asks you to enter a number, then adds that number to the selected cells.

In the macro code, I use 7 as the set number, and the default number, because I have several weekly tasks. Once they’re completed, I add 7 to the date, to move them to next week’s schedule.

You could change the code, so the set/default number is something that you use frequently.
