Should I buy this? Seven questions and the 10-minute rule
Updated
Impulse buying is a purchase decided by a feeling rather than a plan — the urge arrives, and the buying is how it gets resolved. A short pause works because the urge is the part that fades: give it ten minutes with nothing to feed it and most purchases become an ordinary decision you can make either way.
This page is that pause, written down. Seven questions to ask before you buy, in the order that catches the most, the ten-minute rule and the reason it works, and a cooldown ladder for anything too big to decide in ten minutes.
The seven questions
Ask them in order and stop at the first honest no. They are deliberately weighted towards not buying, because the moment you are asking them is the moment your judgement is at its worst.
- Did I want this yesterday? If the want is younger than the ad, it is the ad’s want.
- What am I feeling right now? Bored, tired, anxious, rewarded — name it. The purchase is usually an answer to that, not to a need.
- Where will it live? Picture the exact shelf, drawer or corner. If you cannot, it becomes clutter on arrival.
- What would I do with the money instead? Not “save it” — the actual thing: the trip, the debt number, the fund. Buying is choosing this over that.
- Would I buy it at full price? If the discount is the reason, the discount is not saving you anything.
- Do I already own something that does this? Nearly always yes, and it is nearly always fine.
- Will I remember wanting it next week? Most impulse purchases would fail this one, which is why the next section exists.
Seven yeses is rare. When you get them, buy the thing without guilt — that is what the questions are for. The point was never to stop buying, it was to stop buying by accident.
The ten-minute rule
The rule: when you want to buy something, wait ten minutes before you do, with the phone face down. Then decide.
It works because of the shape of an urge. An urge does not climb steadily until you satisfy it; it rises fast, peaks, and falls on its own if nothing feeds it — the same curve people learn to ride out with cravings of every kind. Ten minutes is long enough to get over the peak and short enough that you will actually wait, which is the only thing that matters about a rule.
Two details decide whether it works. The phone goes face down, because attention is what keeps an urge alive — the open tab, the second look at the photos, “just checking the price”. And the timer runs on the clock, not on the screen: if you have to keep the app open to keep the countdown going, you are staring at the thing you are trying not to buy.
After ten minutes, ask the seven questions. If the answer is still yes and the purchase is small, buy it. If it is not small, it goes on the ladder.
The cooldown ladder
Ten minutes handles the urge. It does not handle a decision that deserves more than ten minutes of thought, which is what the cooldown is for. Put the item on a list — a wishlist, a note, anywhere that is not the basket — and give it a wait matched to the size of the purchase.
| Size | What “size” means for you | Wait | What the wait is for |
|---|---|---|---|
| Small | You would not notice it on the statement | 24 hours | Sleeping on it. Most of these are gone by morning |
| Medium | You would mention it to someone | 72 hours | Long enough to price the alternatives and check whether you already own one |
| Big | You would have to move money to pay for it | 7 days | A full week of ordinary life, so the decision is made on a normal day rather than the day you saw it |
The cooldown is the only rule on this page that gets more effective with time rather than less. A 24-hour rule catches the impulse; a 7-day wait catches the thing you convinced yourself of over three evenings. When the wait ends, the question is not “do I still want it?” — you might — but “did I think about it at all?” If the item did not cross your mind during the week, that is your answer.
The whole decision, on one page
What to do with this tonight
Pick the next thing you want to buy — there is usually one in a tab already. Close the tab. Set a ten-minute timer, put the phone face down, and do something with your hands. When it goes off, ask the seven questions and stop at the first no. If you get to seven, decide the size, and give it its wait on a list.
That is the entire method, and it costs nothing. If you would rather not run the timer yourself, NoBuy has a “Tempted?” button that runs the ten minutes for you — on the clock, with the phone locked — and a wishlist that asks “Still want it?” when the cooldown ends.
Questions
Does the 24-hour rule actually work?
For most ordinary purchases, yes — the urge that made the thing feel necessary is usually gone the next morning, and what is left is a plain decision. It has two known failure points. It does nothing against artificial urgency, because a countdown timer is designed to make 24 hours feel impossible; and it fails when the basket stays open in a tab, because the item keeps re-triggering the urge. Close the tab, write the item down, and the rule works far better.
What if I miss the sale?
Then you missed a sale, which is a different thing from losing money. A discount only saves you anything on a purchase you were going to make at full price; on anything else it is the reason you are buying. Sales also recur — the same item is discounted again within weeks more often than not. If, after the cooldown, you still want it and it is no longer on sale, that is the clearest possible answer to "would I buy this at full price?".
How long does an urge to buy something last?
Shorter than it feels. An urge rises fast, peaks, and subsides on its own if nothing feeds it — for most people the peak passes within a few minutes, which is why a ten-minute pause is long enough to change the decision and short enough that you will actually do it. What keeps an urge alive is attention — the open tab, the second look, the "just checking the price" — so the pause works best when the phone goes face down.
Is impulse buying a habit or a symptom?
Usually a habit, sometimes both. For most people it is a learned loop — a feeling, a scroll, a purchase, a small relief — and loops can be interrupted with a pause and replaced with something else. If the loop is running most days, if purchases are hidden or followed by real shame, or if the relief is the only thing that reliably lifts your mood, it is worth talking to someone, because then the buying is doing a job that a rule will not do on its own.
