percent change in time

[claven123]

I'm looking to calculate the percent change in time. I have time as 1:14 and 2:05. I guess I can format it any way needed (do I need to format it any specific way). I also converted it to minutes.

The formula I'm using is..... (new value - old value )/old value * 100

=((J16-J15)/J15)*100

Thanks,

Looks ok to me, with some test data entered and also converted to seconds provides the same percentage 61.91892%
