Show number in thousand (k) or in million (M) by using custom format

The custom format to show number in thousand or in million is simple:

  • #,##0,“k”
  • #,##0,,“M”

The “k” or “M” is optional, depend on whether you want to show it in the header or in the figure itself.

Excel Tips - Custom Format 1

The trick is to put 1 comma and 2 comma at the end of the format setting (#,##0) for “thousand” and “million” respectively.

Nevertheless, do you know how it works?

Think about a number like 1000000.  When you apply custom format #,##0 to it, it shows 1,000,000.  The comma (,) we use in the custom format is simply the thousand separator.

When we put one more comma at the end without specifying the format (# or 0) after it, it means “Show Nothing”.  Put it in other words, we cross out the final three digits with a comma.

  • Applying #,##0,“k” to 1000000 –> 1,000,000k –> 1,000k
  • Applying #,##0,,“M” to 1000000 –> 1,000,000M –> 1M

As mentioned, “k” or “M” is optional.

When we see, we remember. 🙂

    That works a treat for me. I have many different users accessing and editing a spreadsheet on SharePoint and I wish them to input as £20K, £100K (instead of 20000, or £20,000 etc) for the sake of consistency. The format I have used is £#,##0,”K”
    This happily converts all entries as per the example above to £20K, or £100K etc. However, If someone were to input £20,800, it still appears as £20K. Is there any way of making it £20.8K without adding .0 to the other entries? Hope this makes sense.

    Great tip on custom number formatting. I often feel that this feature is one of the most underutilized in Excel. Below is my article on other custom number formatting tricks. Look forward to reading more from you.
