Cost of supplies: Growing your own food sounds like a good way to trim expenses; that is, if you already own pots. a trowel, tomato cages, a cultivator, a shovel, a spade, a garden rake, a leaf rake, a weeder, a hoe, a pesticide sprayer, garden gloves, a hat, knee pads, a garden hose, a sprinkler, a fertilizer spreader, a compost bin... you get the idea. Taking these expenses into consideration, that that tomato isn't such a bargain.
In the same manner, I have a shelf full of tools I bought to use once, the expense for which I will never recoup. For example, the bookshelf that I bought a router to build -- a router I haven't used since -- ended up costing me over $120. I could have bought a better bookshelf for $40 at Staples. And don't even mention my chop saw, Dremel tool, pipe wrench...
Time sucks: How much is an hour of your life worth? If you don't enjoy the DIY job you take on, ask yourself, would I work for this wage? Gardening again is a good example. You may reap a harvest of 100 pounds of string beans, but by the time you do they'll be in season and every grocery will be selling them for $0.39 a pound. So you'll have $39.00 worth of string beans. If you put 8 hours total into those beans, you were working for under $5.00 an hour.
I've fallen into the money vs. time trap again and again, often because I have to go to the hardware three times for every job. Clearing brush, laying a brick sidewalk, installing a garage door, painting porch railings, running new phone lines; I've wasted countless hours just to save a buck or two an hour. What are your time sucks?
Lack of expertise: The worst aspect of this money trap is that, by doing something ourselves, taxes, for example, we never learn just how much money it really cost us. I've fancied myself at various times capable of installing a hard drive in my computer, hanging a ceiling fan, pruning my birch tree, patching my membrane garage roof, tuning my recumbent bicycle, and doing a brake job on my van. Each time I was forced to admit defeat and resort to that most foul-tasting of money traps, paying an expert to clean up my mess.
Of course, the list above contains many activities that people find enjoyable, and in that case, the difference between hiring to get the job done and doing it yourself can be written off as recreation. If you don't enjoy a task, however, before you do it yourself to save money, calculate your total expense -- in supplies, time, and the potential to screw it up for lack of expertise. I suspect you'll farm out a lot more jobs.
