Mental accounting
A rupee is a rupee. But our brains file money into different mental accounts and treat each one differently.
Not all rupees feel equal
The economist Richard Thaler called it mental accounting. A ₹20,000 Diwali bonus feels like “free money” and gets spent on something special. The same ₹20,000 from salary would be treated carefully. A tax refund, a gift, a win at cards: each lands in a mental account with its own rules.
The result can be strange: people carrying credit card debt at 36% a year while holding an FD at 7%, because the FD is “for my daughter” and the card is “just monthly spending”.
Emergency
90% full
Home
45% full
Travel
70% full
When it hurts and when it helps
Mental accounting hurts when it hides the true cost of a choice, as with the card and the FD. It also hurts when “found money” is spent on things you wouldn't buy with earned money.
But it can help. Labelled accounts (“house fund”, “emergency fund”, “travel”) make each goal feel real and protect it from casual spending. The trick is to use labels deliberately, while doing the maths across all of them.
Practical rules
Treat windfalls like salary: decide a split in advance, for example half to goals, a quarter to debt, a quarter to enjoy. Before holding savings, check whether any debt costs more than those savings earn. Use separate accounts for goals, but review them together once a quarter.
Key takeaways
- 1Money is interchangeable, even when it doesn't feel that way.
- 2Clear high-interest debt before holding low-yield savings.
- 3Decide how to split windfalls before they arrive.
