ROUNDDOWN Formula Main

How to use the ROUNDDOWN Function

The ROUNDDOWN Function Rounds a number down (towards zero) to a specified number of digits.

Round down to Nearest Whole Number

To round down to the nearest whole number set the num_digits argument to 0.


Rounddown Whole Number

Round down to Two Decimal Places

To round down to two decimal places, set the num_digits argument to 2. Here we will round down a price to the nearest cent:


Rounddown Two Decimal

Round down to Nearest 10, 100, or 1000

To round down to the other side of the decimal (to 10, 100, or 1000s), use negative numbers for num_digits:


Rounddown 10 100 1000

Round down Percentages

When rounding down percentages remember that percentages are decimal values. So to round down to the nearest whole percentage use the ROUNDDOWN Function with num_digits = 2.

Range("C3") = Application.WorksheetFunction.RoundDown(Range("A3"), Range("B3"))
Range("C4") = Application.WorksheetFunction.RoundDown(Range("A4"), Range("B4"))
Range("C5") = Application.WorksheetFunction.RoundDown(Range("A5"), Range("B5"))
