I have a substantial line item in my budget I call accrued expenses (even though I don't actually accrue in the business sense), with subcategories as shown below. It's for unexpected expenses, most if not all with a frequency of more than a year. I've projected expenses for each year out to 2054 including what I expect for
- Appliances (Dishwasher, Washer, Dryer, Fridge, Stove, HVAC),
- Car DH after trade in,
- Car DW after trade in (both cars every 5 years),
- Furniture (Bed, non-appliance furniture),
- Home Remodel/Major Maint (Roof, Paint etc.),
- PC TV Electronics & Travel (Major Vacations).
I've planned them to be staggered as much as possible, but they still flucuate considerably, ranging from $200 to about $25000 in any given year, averaging about $9500 per year.
Like REW, I just take the hit in the year it comes, but I've planned all these "hits" in by accruing for them until the projected end of plan. This year I actually took hits for bathroom remodel, having the house painted & a new bed.
Has to be accounted for somehow, only way I could figure to do so. The way I'm doing it, accrued expenses account for about 20% of my budget, though I expect to spend less than projected. And it doesn't confuse the issue for us as I track variances for each category using Excel pivot tables, so I can still "see" how we're doing on operating expenses apart from the major unusual or accrued expenses.
EDIT: Having read various approaches from later posts, all of them are good and workable, therefore individual choice. As long as these non-regular major expenses are built into the plan somehow, there's no wrong way to account.
