The 30-Day Rule

Why it works

Most impulse buys are about the feeling of the moment. A wait separates the want from the moment. You still buy the things that matter, just fewer of them.

The rules

  • Any non-essential purchase over an amount you choose (say $30) goes on the list with the date.
  • Wait 30 days. Do not keep it in an online basket.
  • After 30 days, buy it only if you still want it and can pay in cash or in full.

The plan

  1. Day 1Choose your limit and start the list on your phone.
  2. Every dayAdd anything you are tempted by. Tick the day.
  3. Day 30Review the list. Buy what still matters and cross out the rest.

Tips

  • For cheaper items, try a 24-hour or 7-day rule instead.
  • Add the item’s price in hours of work next to it. Our hours of work calculator works it out.

If you slip

Bought something on impulse? Note it on the list anyway, with how you feel about it a week later.

When you finish

Many people keep the rule for good. It works best as a habit, not a one-off.
