I keep an excel sheet of all my expenses and I'm looking to convert the price of something I buy into the number of hours/minutes it would take me at work to earn that amount.

I make $14.25/hour which is $0.2375 cents per minute.

So if I buy something for $17.63, it should show as: 1 hour 14 minutes. ($14.25 = 1 hour, so $17.63 - $14.25 = $3.38 left over divided by $0.2375 cents a minute = 14 minutes.)

How can I get that to show up for each expense amount in a column?

Thanks!
