Putting all those details into excel would be very taxing. And if you lost it, that would be an excel recovery nightmare, probably. I would really suggest something like an online cook-book or calculator.
I can understand how you feel, and I take it that it'll depend on which thing you have more of an affinity for. Each one has its pluses and minuses. My preference is excel for a few reasons:
1. I don't have to depend on getting online to get to my information. [keeping things at hands reach is always a plus, just in case the server's down when you want to get a hold of your info.]
2. You can make adjustments for larger and smaller volumes in an excel spread sheet and have it calculate your info and give you your results.
3. I like the interface. It's something I'm familiar with, with a very small learning curve and for the data entry portion to get the info added I've got a great teen at home who loves making her spending money by handling those types of tasks while learning innovative ways to get through the workload quicker and more efficiently.
But I will do an online search for some more solutions to choose from.
Thanks for your input.
