What their primary heat source is. $300-$600 is actually pretty typical for someone who heats with electricity in an old house. We pay roughly the same as you, but we heat with gas and have a newer (70's era) house with upgraded windows etc.
There's lots of variables. I think a better metric is probably if their amount has gone up or down etc. In the country, you're also paying power to pump water etc so it all adds up.
