This tutorial demonstrates how to use the FLOOR Function in Excel to round a number down.
How to use the FLOOR Function
The FLOOR Function Rounds a number down, to the nearest specified multiple.
Round down to Nearest 5, 50, or .5
To round down to the nearest 5, set the multiple argument to 5.
=FLOOR(B3,5)
Alternatively you can round down to the nearest .5 or 50 by changing the multiple argument.
Round down to Nearest Quarter
You can also round a price down to the nearest quarter by setting multiple = .25.
=FLOOR(A2,0.25)
Round Time
The FLOOR Function makes it easy to round down time. To round time down to a certain increment, just enter your desired unit of time using quotations. Here we will round down to the nearest 15 minutes.
=FLOOR(B3,"0:15")
Other ROUND Functions / Formulas
Excel / Google Sheets contains many other round functions. Here are quick examples of each:

Below, we will point out a few functions in particular.
CEILING and MROUND
The CEILING and MROUND Functions work exactly the same as the FLOOR Function, except the CEILING Function always rounds up and the MROUND Function always rounds to the nearest multiple.
=MROUND(B3,5)
=FLOOR(B3,5)
=CEILING(B3,5)
ROUNDDOWN Function
Instead of using the FLOOR Function to round down to a multiple, you can use the ROUNDDOWN Function to round a number down to a certain number of digits.
=ROUNDDOWN(B3,2)
FLOOR in Google Sheets
The FLOOR Function works exactly the same in Google Sheets as in Excel:
FLOOR Examples in VBA
You can also use the FLOOR function in VBA. Type:
application.worksheetfunction.floor(number,significance)Running the following VBA statements
Range("C2") = Application.WorksheetFunction.Floor(Range("A2"), Range("B2"))
Range("C3") = Application.WorksheetFunction.Floor(Range("A3"), Range("B3"))
Range("C4") = Application.WorksheetFunction.Floor(Range("A4"), Range("B4"))
Range("C5") = Application.WorksheetFunction.Floor(Range("A5"), Range("B5"))
Range("C6") = Application.WorksheetFunction.Floor(Range("A6"), Range("B6"))will create the following result
