The cost of electricity is different in every state. The next electric bill you get, or look up your electric company online and see what they charge for a KW hour and multiply the KW usage of your heater and filter by 8760 ( number of hours in a year) and that's what it costs.
ex. 100 watt light bulb uses .1 KW hour, so .1 x 8760= 876 KW hours a year used. if your elec co. charges .10 cents a KW it costs 87.60 for a 100 watt bulb to be on 24 hours a day 365 days a year.

Let's say the heater is on for 1/3 of the time. In the summer it will be less. In the winter it will be more.
Based on other poster's estimate for a 100 bulb puts it right in the ballpark. With the filter, let's say $100 is average for the year. I'd also consider two 150's or even two 200's instead of a single 300. First, the heat will be better distributed. Second, if one heater stops working (it happens) your fish will not freeze. On the other hand, if it will not shut off (has happened to me several times) it will not boil the fish. Most tanks over 29 gallons, I'd suggest two heaters.

You would have to do a lot of math. It isn't really much to run a tank once it is established.
