Firstly, in most cases we are just DIY'ing the final "craftsman" step of the work, we still depend on the materials being available.
Second, if more and more people that actually care about work quality go DIY it leaves people who can't or won't be as involved. Over time unscrupulous tradespeople will take over the market.
In Denmark the tax system is such that if you subcontract out of personal money they need to be 5 times fast than you.
If we say that you can make your deck in half the time a professional would have don it, the factor is still 2.5x.
Ig. assuming a contractor would do it for 50 USD/h, this would translate to "making" 125 USD on hour by doing it yourself, 250 USD/h if you know what you are doing.
Obviously these things change with tax regimes.
If we assume I'm a contractor charging $100 per hour and take the cash as salary:
(100/1.3142) * 0.5 = $38 left after payroll tax and the top income tax rate (50%).
So if I'm just as fast and good as a professional, the professional needs to charge $38 per hour or less for it to be worth it. But in reality, a professional is probably at least 2x as fast as me, making it $76. That's probably less than they charge, so it's worth paying for a professional.
Then you also need to add some cost of doing business.
Said in another way: The 100SEK you earn becomes 25SEK the contract can use (assuming 50% tax rate) – that's the first factor of 4. The last factor can be found in the details.
After all, if the contractor had some strange anomaly where he pays 100% of his income in tax, why would that matter to you?
Do it yourself: Miss out on that hours worth of salary
Subcontract: 2 times tax is paid.
Obviously this has implications on negotiation. This is exactly the reason why services are considered very expensive in the Nordics (as in 80USD to get your hair cut).
Note that this needs to be compared with a company getting their stuff fixed. Their contractor costs are fully deducted from their income.
In my example, a contractor who's twice as fast needs to cost $76 or less per hour . Thrice as fast is $114 or less.
You're right in principle though, just not on that calculation. In Sweden we have tax deductions for private citizens exactly to combat this issue: up to a certain amount per year can be deducted from your income, just like a company can, for certain services (such as cleaning or house repairs).
Said in another way: you don't pay income tax when you paint your own house.
(Also discussed recently on HN.)
I once wasted my whole holiday on painting the house. And it wasn't well done, because it was my first time. I'll probably not do it again, unless I don't have other work.
If you would have to do it again, would you do the same errors, and the paint job would turn out equal? Or would you do better second time?
That is why I never painted an entire house before having painted a bedroom at least one time. And I've never painted a bedroom before I painted a small piece of furniture at least one time. One needs to learn gradually, hopefully with someone who knows how to do things. Last year I built a terrace and room with the (paid) help of a contractor. I started just carrying the trash, then breaking things, then putting cement of the walls, etc. etc. Now I can quite complex things by myself..
The key is to do things gradually..
I wouldn't work saturday afternoon anyway because my head is already useless for programming. So I do need to change line-of-work somehow. I can either go for a walk and learn something about nature. Or I can self-repair something and learn something about construction.
Of course spending all free time on self-repairs would be exhausting. But I don't feel like lying on a couch entire weekend either.
This is the key! I do these kind of things on my spare time!
On my spare time I could (1) do nothing; (2) try to cram more screen time into my life, and give the money earned to someone to do my repairs for me or; (3) do some things by myself, learn while doing it, and feel like a super-human that can control is own life (well, some of it). I prefer number 3!
So it is more comparable with the work rates, since I do not have a lot time time to tinker
Yes, using power tools while kid is napping is no-go. But after few months kid is not napping that much. And there’re many relatively silent jobs. It’s easy to silicon a window sill while kid is sleeping in another room. Or assemble a drawer with an old good screwdriver instead of a drill. And after a couple years there’re endless learning possibilities. Sure, it goes slowly, but it does happen eventually.
Full disclosure - I did hire handymen for a good portion of jobs for various reasons. Mostly because we were burning a lot of money in rent or some jobs require too many special tools and knowledge to be done right (electricity, drywalls, etc).
I do a lot of repairs and maintenance at my own house. Last year I built a terrace and an extra room, and only had to pay someone to help me, and this week I painted the all house exterior with the help of my dad. Total costs of painting and entire house: 240€. It would cost north of 2000€ if I had to pay someone to do it.
Yes, my "hourly rate" for that kind of work is sometimes much less than my "regular" work. But I can fix many things, don't need to go find "credible" people to do things for me, I fell an immense pleasure to be self-sustainable (for that kind of things), learn a lot; and my house, cars, electronics, are mostly in top shape.
