I can see how that would be a useful system. My approach/mindset is totally different. Instead I maintain a 1 year emergency fund in my checking account. If something important breaks (e.g. phone), I know I can replace it. Every month or so, I look to make sure I’m not drawing down my account balance. If I am, I mentally calibrate to spend less money on takeout, clothes, etc. If instead my balance is going up, I skim off excess money into an investment account.
