I have used a method to gradually move my family into a frugal lifestyle. Hoping this method could help others. Sometimes it is hard to go home one day and say, "We are now going to live a Mustachian lifestyle starting tomorrow. Turn in your cell phones and credit cards immediately so that I can mircomange your lives.", and it might be better to use a less noticeable gradual approach.
What I do is "wait one more day". For example, previously I put gas in the car every 7 days. Next, I changed to every 8 days and let the family adjust to that, and adjusted the amount of driving accordingly, after that 9 days, 10 days, 11 days, and now 12 days. So instead of needing gasoline 4.3 times a month, now I only need gas 2.5 times a month. At $0.50/mile (back of the napkin calculation), about $2,100 savings per year. For groceries, same thing, used to shop every 7 days, and a lot of food went to waste, went to 8 days, 9 days, now we are at 10 days, and adjusted the grocery budget accordingly, a savings of $1,700 per year. Weekly dinner out with the family? Change that to 8 days, then up from there.
The idea is to adjust by a day without anyone even realizing it (nobody notices 8 days vs. 7 days), wait a few months and adjust again. Basically a way to establish an unnoticable habit. I believe by doing this, anyone can easily cut an additional 10% of thier family budget which can be socked away.
Anyone do something similar? Or ways to improve upon this technique?
