Cash's 5 rules for the buffer

  1. 1. Aim for 3 months first. Then 6 if your income is variable.
  2. 2. Separate account. Out of sight = out of mind = doesn't get spent.
  3. 3. Easy access. Savings account, not investments. Markets crash exactly when emergencies happen.
  4. 4. Real emergencies only. Phone broken = yes. Sale at Nike = no.
  5. 5. Refill before investing. Used some for a real emergency? Refill before resuming monthly investing.
