Hmm. I think your disconnect might be due to thinking in terms of budget instead of thinking in terms of what was actually spent the previous year.
But does thinking of what was actually spent, give any useful information? I think it does, perhaps much more useful than pie-in-the-sky budget information. Here's an example. I just got a new furnace and AC system last year. It cost a total of $7200. It will last about 20 years, which comes to $360/year. In the long run, $360/year would not be a very big impact to anyone's budget. But more importantly, since I spent more on the HVAC, I started feeling kind of poor and as a result I unintentionally cut back in other areas to replenish the costs. Actually (in reality), I ended up spending less last year than other years even though the HVAC was included, along with extensive dental work. So, overall it made no impact.
