The 72-Hour Rule: Stop Impulse Spending Before Payday

Most overspending happens in the 72 hours before salary credit, when your brain pre-spends incoming cash. Here is the behavioral fix.

The Payday Pressure Window

Spending behavior research shows a consistent pattern: the three days before salary credit are the highest-risk period for impulse purchases. Your brain, sensing incoming cash, pre-spends it.

The fix is not willpower. It is a rule.

The 72-Hour Rule

Anything above ₹500 that you did not plan goes on a 72-hour waiting list. Not a denial. A delay.

In 72 hours, either the purchase is still essential (buy it) or the urge passed (you saved ₹500+). The AI coach in Mr. Money applies this automatically: it flags unplanned discretionary spending in the three days before your next salary date and asks one question: Still needed in 72 hours?

Why It Works

The purchase intent is emotional. The 72-hour gap is cognitive. By the time you revisit, the emotion has cleared and you are making a rational choice.

Users who enable the 72-hour rule save an average of ₹4,200 per month in the first three months.
