There is no formula that I know of.

How big is the house?

jack's idea will get pretty close for code work. Fancier systems will require more wire. Phone and coax are additional.

Jack: Is that figure using 14ga for lighting only and 12ga for receptacles or are you running some GP receptacles with 14?

Thanks for the replies, house ia 2420 sq. ft. I think Jack has me going in the right direction,, Thanks, Matt

When my Aunt & Uncle built their home about 10 years ago, I was elected to do all the wiring. We sat down to discuss supplies, outlets, ceiling fans, and of course wire needed. My Aunt pops up and says "oh you won't have to buy any wire, I bought a WHOLE ROLL of wire." My eyebrows went up, and I said I don't think that will be enough. She said oh, it's a big roll, 250 feet..... As it turned out, to wire a 1200 square foot 4 room home, we used about 2500 feet of wire total..... but that also was with running at least twice as many circuits and outlets as what code required. It's hard to estimate how much wire is needed without seeing how the house is laid out, but I hope this gives you a general idea.

Don’t worry about the gauge for now but definitely 14 on the lights. I would estimate amongst all the different types of wire you’ll be looking at one roll per hundred square feet
