We are on the budget plan.
It seems, they add up the total volume you used last year, assume you will use the same this year, divide by 12, multiply by the current rate, and there you go. At the end of the year, if you used more, and owe more, you get a bill. If you used less, you get a credit. The next year, your budget is adjusted again, and it starts over.
FWIW - Our Budget is $75, down from $90 last year. I made several modifications between the two years to help in heat retention.
