The 24-Hour Rule: A Simple Trick to Curb Impulse Spending

Ever buy something on a whim — then regret it later?

We’ve all been there. Maybe it was that trendy kitchen gadget, a pair of shoes you didn’t really need, or a limited-time “deal” that seemed too good to pass up. In a world of flash sales, one-click checkout, and endless ads, impulse spending has become second nature for many Canadians.

But here’s a simple habit that can save you hundreds (or even thousands) every year: the 24-hour rule.

What Is the 24-Hour Rule?

The 24-hour rule is a simple personal finance strategy: whenever you feel the urge to make a non-essential purchase, wait 24 hours before buying it.

The goal is to give yourself a “cooling-off period” — time to think about whether you really want or need the item, and whether it fits into your budget. If, after a full day, you still feel it’s worth the money, go ahead and buy it. But more often than not, you’ll find the impulse fades — and your bank account stays happier.

Why the 24-Hour Rule Works to Curb Impulse Spending

1. It fights emotional spending.
   Retailers design marketing to trigger quick decisions. The 24-hour rule breaks that cycle by creating space for logic over emotion.
2. It helps you stick to your budget.
   By pausing, you’re automatically reviewing your finances — even subconsciously. You’ll think, “Do I actually have room for this right now?”
3. It makes you appreciate your purchases more.
   When you do buy something after waiting, it’s more intentional — and usually something that genuinely adds value to your life.
4. It prevents buyer’s remorse.
   Canadians collectively spend billions on items they later regret. A short pause can prevent that “why did I buy this?” moment.

How to Use the 24-Hour Rule in Everyday Life

For Online Shopping:

Add an item to your cart or wish list, then set a reminder for the next day. If you still want it after 24 hours, and it fits your budget, buy it. As a bonus, many stores will even email you a discount code to encourage you to come back and complete your purchase.

For In-Store Purchases:

Snap a photo or write down the details. If you’re still thinking about it tomorrow, go back for it – chances are, you won’t. Having time to think about it and considering the effort to return to the store for the purchase will usually give you your answer.

For Big-Ticket Items:

Extend the wait time. Try the 72-hour rule or even a one-week rule for anything over $200 – $500. When a purchase starts to become a portion of your entire paycheck, it deserves a greater consideration time.

Bonus: Start a “Want List”

Instead of buying something right away, jot it down on a Want List. At the end of the month, look back — you’ll likely notice how many items no longer feel important. Use that money instead to boost your emergency fund, pay off debt, or contribute to your TFSA or RRSP.

Real Example: How the 24-Hour Rule Saves Money

Let’s say you usually spend $40 each week on impulse spending — a new candle here, an app subscription there. That’s over $2,000 a year in unplanned spending.

Even if the 24-hour rule cuts that in half, that’s $1,000 in savings you could put toward travel, debt repayment, or an emergency cushion.

The Bottom Line

The 24-hour rule isn’t about saying no to everything — it’s about saying yes to what truly matters. By giving yourself a day to pause and think, you’ll make more intentional spending decisions and naturally grow your savings over time.

Small habit, big impact.
