# Rounding to the Nearest Quarter Hour

by Allen Wyatt
(last updated April 25, 2019)

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)
```

@Monica
This little macro will do the job:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column <> 1 Then Exit Sub
Application.EnableEvents = False
Target = Round(Target(1) * 96, 0) / 96
Application.EnableEvents = True
End Sub

Just enter the hour (hh;mm) in a cell of column A and the macro will automatically round it.

If you use another column to enter the date, adjust <>1 in the first row: <>2 for column B, <>3 for column C ...

Attention: this macro must reside in the worksheet's code page (not in a module). Right click the worksheet tab and select View Code. That's the place to be.

Hi Allen, Thanks for the tip. It worked perfectly but, I am hoping you can tell me how to calculate both the time elapsed AND round the elapsed time to the 1/4 hour in ONE cell? I am working with very limited space so calculating the time elapsed in one cell then rounding it in a second cell is not desired. Thanks for your help!

After further testing the following might be better

=IF(MOD(MINUTE(B3),15)<=5,ROUNDDOWN(B3*96,0)/96,ROUNDUP(B3*96,0)/96)

It handles people arriving after (:30, 9:45 and so on.

EdnaAssuming that the Start Time is in B3 one way is to insert a column before the End Time to Adjust the Start Time using this formula:=IF(B3>TIME(HOUR(B3),5,0),ROUNDUP(B3*96,0)/96,TIME(HOUR(B3),0,0))[{fig}]HTH

Great Article! So I am trying to figure out a '5/10 minute rule.' So if the employee works 10 minutes in the quarter hour period they will be paid for 15 minutes. Anything less than 10 minutes in that quarter hour, they will not get paid for the quarter hour.
So if they clock in at 8:06, they will not get paid from 8:00 to 8:15. But if they clock in at 8:05, they will get paid from 8:00 to 8:15.
Currently, we use the 'counting on our fingers method.' Would like to have a spreadsheet for this.
Thanks

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?

Hi, thanks for the tip.
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.

2-Apr-17 4:53 AM 12:00 PM 12:30 PM 2:30 PM 9.12 0 I AM TRYING TO CREATE A FORMULA THAT WILL ROUND DOWN TO 9 HOURS WITH AUTOMATICALLY SETTING THE TIME SHEET IN THIS FORMAT. I CANT SEEM TO FIGURE THIS OUT. I HAVE WORKED SEVERAL SCENARIOS AND I JUST CANT FIGURE IT OUT.

my Cells

B6 C6 D6 E6 F6
Time In Lunch Out Lunch In End Time Total Time
4:53 AM 12:00 PM 12:30 PM 2:30 PM 9.12

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.

@Samantha,

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

Hi this formula is what I am looking for however, I need the formula to calculate backwards for example
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

I overlooked the round part.

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

2016-11-01 13:37:50

Willy Vanhaelen

@Kari

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.

I am trying to add hours and round them to the nearest .25. If an employee works from 12:30 pm- 5:00 pm, I need the answer to be 4.5 hours. If I use =sum(c2-b2), I get 4:30, but I am wondering how to get 4.5 hours instead.

I am trying to enter a rounding formula for a time sheet. With a start time of 07:53, lunch 12:00 - 13:00, time out @ 17:01. I need it to round to the nearest quarter of an hour but the formula I am using is still giving the employee and extra 0.25. The formula I have is =ROUND((D8-B8+H8-F8)*96,0)/4. What formula can I use so that the total hours is 8 and not 8.25?

Thank you

How does the first formula: =ROUND(A1*(24*60/15),0)/(24*60/15)
reflect all the conditions expressed in the first paragraph?
