It's not going to cost pennies, it's an easy calculation treat energy efficiency as 100% efficient and calculate how much watts you would need to put say a 10,000KG payload in orbit and then calculate how much it would cost you in terms of electricity.

F (d)x/(d)t = F * v = m * a * v = joules per second = watts

Please see my response to kragen, where I derive the cost.
