Start Excel and open the worksheet containing the number you want to round up. Click inside of the cell where you want to display the calculation. Type "=ROUNDUP ()" into the formula bar.

There are 3 methods to use the ROUNDDOWN function in Excel to round up numbers, and we have explained all of them in this post.

Enter "Roundup (A1,-1)" without quotes in any empty cell. Change "A1" to your actual cell reference. The "-1" in the formula tells the Roundup function to round up to the nearest ten.
