**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007, 2010, and 2013. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Rounding to the Nearest Quarter Hour.

Lisa is trying to set up a timesheet. It needs to go by the seven-minute rule. If it is 7 minutes till the hour it rounds to, say, 8:00 am; if it is 10 till it rounds to 7:45. If it is 7 minutes after it would be 8:00, and 8 minutes after would be 8:15 am. In other words, whatever time is entered needs to be rounded to the nearest quarter hour.

The full name of the rule that Lisa mentions is the "7/8 minute rule." It's a throwback to when timecards were processed manually. Depending on the particular time clock, the rule may not have the same result as quarter-hour rounding. Consider that the 7/8 rule rounds down all the way to 7 minutes and 59.9 seconds whereas quarter-hour rounding rounds down only to 7 minutes and 29.9 seconds. It's not a huge difference, but the 7/8 minute rule in a payroll context gives employers a 30 second freebie.

If Lisa is only entering hours and minutes, then quarter-hour rounding is just fine. This can be handled in a number of different ways. For instance, you could create a lookup table that shows what the rounded time would be for each time within the hour, and then—based on the number of minutes in the original time—use VLOOKUP (or one of the other lookup functions) to determine the correct minutes.

A better way, however, is to remember that Excel stores times as a fraction of a day, so to convert any given time to minutes you simply multiply a time value by the number of minutes in a day (24 * 60 = 1440). You can then divide by the desired time interval, in this case 15. This means that you can use any of the following equivalent formulas, if the time you want to round is in cell A1:

=ROUND(A1*(24*60/15),0)/(24*60/15) =ROUND(A1*(1440/15),0)/(1440/15) =ROUND(A1*96,0)/96

If you prefer, you can also "reverse" the formula by using any of these equivalent formulas:

=ROUND(A1/(15/(24*60)),0)*(15/(24*60)) =ROUND(A1/(15/1440),0)*(15/1440) =ROUND(A1/0.01041667,0)*0.01041667

If you have the Analysis ToolPak enabled on your system, you could also use the MROUND function to determine the rounded time. The following are equivalent formulas that use the MROUND function:

=MROUND(A1,15/60/24) =MROUND(A1,0.25/24) =MROUND(A1,0.01041667)

If you are not comfortable figuring out the number that Excel uses to represent 15 minutes (as is done in these formulas), you could combine MROUND with the TIME function, in this manner:

=MROUND(A1,TIME(0,15,0))

As mentioned, all the formulas presented so far assume that seconds are not being entered into the original value. If they are being entered and you want to use the 7/8 rule exactly (favoring the employer for that half minute), then you need to use an adapted formula, in this manner:

=ROUND((A1*1440-0.5)/15,0)*(15/1440)

Round to the nearest 1/2 hour, but note that 4:15 rounds up 4:30 which is surely what you want.

=MROUND (A1,TIME(0,30,0))

Why not just join the 21st century and pay to the nearest hundredth of an hour?

Is there a way I can specify then to round up and round down?

For example, if time worked is 4hr15, it is rounded down to 4 hrs, but if it is 4hr 16+, it is rounded up to 5hrs.

I am trying to set it up to where if I am out one day my assistant can just plug in the time such as I listed above, it is set up in formula and we can do calculations much easier. I'm lost.

Try: =FLOOR(A1,15/24/60)

if an employee clocks in in between

8:00 and 8:15 then the clock in time should read 8:00

8:15 and 8:30 then the clock in time should read 8:15

8:30 and 8:45 then the clock in time should read 8:30

8:45 and 9:00 then the clock in time should read 8:45

Thanks-worked perfect.

@Kari

I overlooked the round part.

Here is the formula: =ROUND((C2-B2)*96,0)/4

2016-11-01 13:37:50

Willy Vanhaelen

This formula will do =(C2-B2)*24

See to it that the cell isn't formatted as a date.

A number format or General will do.
