I'm a slightly better than average web technologist. I have a very limited understanding of computer programming, and a below average eye for design. Most crucially, I have a fairly strong grasp of search engine optimization.
Two years ago, I built 3 little websites in a week's time that have brought be about 50 cents per day each ever since with no additional effort. I never appreciated what this really meant until I started reading Jacob's ideas on this blog and doing some of the math myself.
Let's find out the investment equivalent value of one of these tiny sites. Fifty cents per day for 365 days is $182.50. I need to subtract my expenses which are about $12.00 per year per website, bringing us a figure of $170.50.
Here's where Jacob's math comes in - multiply any annual expense or income by 25 to get the investment equivalent amount, which is the amount you need to have saved to pay for that expense forever. $170.50 in passive revenue needs a savings of $4,262.50 invested in a fund that pays 4% over the rate of inflation. This effectively means that each little site I build is on average equivalent to $4,262.50 in the bank (the word "bank" used loosely here)
I did this calculation just 2 days ago and was completely floored. Immediately I started building these little sites again full time. I can easily put 2 sites together in a single day, probably 3 or 4 if I really wanted to push myself. There are people with much stronger programming skills than I have who automate the production of hundreds of these sites an hour, but the quality and income of each site is extremely low. I don't like to push myself though, so I'll assume that 2 sites is the max I can comfortably produce on average.
Here's where my second thought experiment came in: what if I built these sites full time for a year - what would the equivalent in investment savings be. It's an easy enough calculation to make - I'm assuming 20 work days in a month (2 less than the average full time worker) and 12 months of work a year:
20 days x 12 months x 2 sites a day x $4,262.50 = $2,046,000 in my chosen investment equivalent income producing asset.
So am I going to start doing these sites full time? Probably not for too long, because I'm not a very hard worker and a full time job, even a self employed one, interests me very little. Right now I'm on a mini-site marathon to 38 sites though, since that's the threshold I need to reach to pay my rent every month for as long as the internet is around! I'm already 7 sites down, 31 left to go. If I work at a leisurely pace, I should have everything set up by the end of next month.
So I wanted to issue a very heartfelt thanks to Jacob for changing how I think about money. I'd love to buy you a beer sometime. Once I reach my first milestone of $18.75 per day in passive revenue, I promise I'll buy your book
