Round, RoundUp and RoundDown in Excel

 May 08, 2015

This article explains the three functions to round numbers in Excel – the ROUND, ROUNDUP and ROUNDDOWN function.

Note: Before your start, if you round a number, you lose precision. If you don't want this, show fewer decimal places without changing the number itself. Also,  mathematically, the numbers 1, 2, 3, and 4 get rounded down while 5, 6, 7, 8, and 9 get rounded up.

ROUND
  • Round a number to two decimal places: =ROUND(A1,2)
  • Round a number to one decimal place: =ROUND(A1,1)
  • Round a number to the nearest integer (or whole number): =ROUND(A1,0)
  • Round a number to the nearest 10: =ROUND(A1,-1)
  • Round a number to the nearest 100: =ROUND(A1,-2)
ROUNDUP

The ROUNDUP function always rounds a number up (away from zero).

  • Round a number up to one decimal place: =ROUNDUP(A1,1)
  • Round a number up to the nearest integer (or whole number): =ROUNDUP(A1,0)
ROUNDDOWN

The ROUNDDOWN function always rounds a number down (toward zero).

  • Round a number down to one decimal place: =ROUNDDPWN(A1,1)
  • Round a number down to the nearest integer (or whole number): =ROUNDDOWN(A1,0)
