I agree with Bowsd, I take a similar approach except I go more by the median than the average. For an odd number of items, the median is the number in the middle, go figure. But for an even number of items such as in Bowsd's example it would be the average of the middle two numbers (200 and 180) which is $190. This is pretty close to the average $187.50. It depends on your situation, sometimes the median number is higher than the average and vice versa but the gap can become wide. For example your median can be 198 while your average is 150 if you take alot of months into account.
The median is easier to eyeball and at least in my case has been a better approximation to what I will typically spend on a bill. For minimum balances on CC or other accounts you might want to or need to pay little by little, I go with the MODE (taking it back to basic arithmetic). That's the number that occurs most often in a set which typically tends to be $21 for some of my cards. But I guess if you had this case, it wouldn't be much of a fluctuating bill.
Of course going with the highest you've ever paid is always the safest amount to budget for. I find the best approach if you aren't going with the highest amount is to be aware of your bills that can be compressed if necessary. These can be food, gas, and entertainment, etc. If your bill comes for energy and you were expecting about $200 and its $500. Quickly adjust your budget and come up with ways to compress these. To compress the food bill, make a light lunch at night to take with you to work the next day so you don't have to eat out. To compress the gas bill, put the car keys up for the night when you get home after work. Sit down and write up a list of everything you need to do before driving away from the house. Nothing inflates a gas bill more than going to Walmart then back home, then going to the mall next to Walmart, then back home, then going to the food place next to the mall and heading back home and turning around to get something you forgot to get at Walmart. Compressing the entertainment bill is easy. DON'T DO ANYTHING. Its fun after a while. You find ways of being creative and you can actually see the money your not spending on stuff you don't need.
