The first formula below seemed to work perfectly in the test runs, thanks!
I'll add it to my main overtime spreadsheet and give it a whirl.

It's easier now just to put the actual times and then let Excel round only
the last total figure rather than the reverse as we've been doing up till
now. By putting in the actual real minutes rather than rounding each day
and _then_ rounding in last figure, I believe that reflects the truer
overtime worked. Very kewl! :oD

Hi,

Try this:

=TIME(HOUR(SUM(C4:C20)),ROUND(MINUTE(SUM(C4:C20))/15,0)*15,0)

or this:

=ROUND(SUM(C4:C20)/0.0104166666666667,0)*0.0104166666666667

or this (you'll need the Analysis Toolpack installed for this one):

=MROUND(SUM(C4:C20),0.0104166666666667)

Regards,
KL

If we have a column of times we're adding up in a formula like, say,
=sum(C4:C20) and we're dealing with times is there a way to modify
that formula so that it rounds the total to the nearest quarter hour?

p.s., since the spreadsheet had to take into account "negative" hours
in terms of subtracting hours, the spreadsheet is set to the 1904
system. Don't know if that makes any difference to the above.
