30-Day Wish List Calculator
Enter when you started wanting it and pick a cooling-off length - thirty days is the classic. The calculator gives the buy-on date: purchase then if you still want it, or let it expire silently if the feeling did.
Anti-impulse advice says wait; this one dates the wait. Wanting is a chemical event with a half-life, and the calendar is how you let it decay without willpower - most list items simply stop mattering, and that is the entire saving.
How to use
- Enter the date the wanting started - the day you first opened the tab counts.
- Read the buy-on date and write the item on a real list; close the tab.
- On the date, run the gate: still want it, does it fit your life, can you pay without borrowing - all three, then buy guilt-free.
Frequently asked questions
What is the 30-day rule for purchases?
Note the want, wait thirty days, and buy only if the want survived. It works because desire decays measurably faster than prices rise: the surge that made the purchase feel inevitable usually expires sometime in week two.
Does the waiting rule work for small purchases?
Use shorter cooling-offs - seven days for small wants, fourteen for medium - the decay curve is the same at every price. The habit matters more than the duration: wanting, dating, and deciding instead of tapping.
What if the price rises while I wait?
Sometimes it does - and sometimes it drops, especially with alerts set on a wish list. The rule's savings come mostly from the items that expire, not the timing; a price alert catches the drops without keeping a tab open.
What are the three questions before buying?
Still want it after the wait, does it fit your actual life, and can you pay without borrowing or a payment plan. All three yeses make it a decision rather than an impulse - and decisions deserve to happen.
