Simple math, you take the number you want to round and you divide it by the number you want round up to (make sure neither are 0 of course) and you take the whole number of that division and multiply it by the number you want to round up to:

    Private Function RoundNumber(Number As Integer, RoundTo As Integer) As Integer
        If Number > 0I AndAlso RoundTo > 1I Then
            Return CInt(Math.Round(Number / RoundTo, 0I) * RoundTo)
        Else
            Return Number
        End If
    End Function

Rounding up or down to incremental value

Code for a Console application which will give results for rounding to the nearest increment (which could be either higher or lower). Also shows results for rounding up or down using the stated increment.

        Dim number, roundup, result As Integer
        Console.WriteLine("Round a whole number to the nearest desired increment")
        Console.WriteLine()
        Console.Write("Enter number to round:  ")
        Integer.TryParse(Console.ReadLine, number)
        Console.Write("Enter increment value:  ")
        Integer.TryParse(Console.ReadLine, roundup)
        Console.WriteLine()
        If number > 0 AndAlso roundup > 1 Then
            result = CInt(Math.Round(number / roundup)) * roundup
            Console.WriteLine("The nearest round number is:  " & result)
            Console.WriteLine()
            result = CInt(Math.Round((number + (roundup / 2)) / roundup)) * roundup
            Console.WriteLine("The number rounded up is:  " & result)
            Console.WriteLine()
            result = CInt(Math.Round((number - (roundup / 2)) / roundup)) * roundup
            Console.WriteLine("The number rounded down is:  " & result)
        End If
        Console.ReadLine()
