I'm trying to develop a formula for what to charge for wedding cake deliveries. None of the cakes I've done so far are local and I need a better system of calculating charges. I live in Philadelphia and I deliver cakes to Maryland and DC, as well as New Jersey and New York. Most people charge per mile, I’ve seen it anywhere between $.60 - $2/mile, but that won't work out for me. If I deliver to say Scranton, PA which is 110 miles north of me and charge $1/mile, that's $110. It would take me 2 hours (each way) and the tolls are like $4 total or something in that ballpark. However, if I deliver to Newark, NJ, that's only 80 miles ($80) and it would take 2 hours or more each b/c the traffic is much worse. The tolls are also WAY higher. So as you can see, delivering to some places I end up losing money if I do this per mile system because in some areas, tolls are higher and traffic is worse. So my new idea is to charge 3 separate fees to make it fair for everyone. A toll fee (if any), a time fee ($X/hour each way; I’m still working out this amount, but probably something like $12/hour...?), and a gas/mileage fee. It's just the last part that has me stumped. I also like this way of doing it b/c when gas prices go up and down, all I have to do is change that one part to get my delivery price. Right now gas is pretty cheap (compared to how it was all summer) at $1.59-ish for premium. My car gets about 20 miles to the gallon and I can drive about 4 hours on a full tank of gas. So based on that, can anyone toss some fair ideas out? Thanks.
