Working from home vs communting

[Scothew]

hey all, wanted to get some opinions.

I have a meeting in the morning for a company and the owner has said that he wants to make an offer for me to come work for him. My question is, what difference in salary would you think it would roughly take to make up for the fact I work at home now.

things ive been trying to think of and factor in is drive time, i'll be working roughly 50min from home (i live in a rural area). I'll go from not driving to driving roughly 85-90 miles a day. Food cost while eating out, clotching expenses, car maintence are all factors ive been trying to figure out.

Gas is roughly 3.62 a gallon here on average I think, which is the birmingham AL area.

Just thinking, A rough bare minimum to really keep me at the same pay scale im at now would be a $7,000 a year increase over what I make now to justify me loosing the time and money i'll be out by introducing commuting again.

Thanks in advance
