Key idea
You don't need to log every chai. You need to know your numbers well enough to make decisions. That's a much lower bar.
Tracking has a reputation problem. People imagine colour-coded spreadsheets and daily data entry, try it for nine days, and quit. The goal was never precision to the rupee. It's awareness, and awareness is cheap.
Three levels: pick one you'll actually keep
Light (most people)
- Check your bank + card statement once a week
- Skim, don’t log; just notice patterns
- 5 minutes, Sunday evening
Detailed (if you’re curious)
- Use an app that auto-categorises spends
- Review categories monthly
- Best for a fixed 2 to 3 month audit
The single most effective habit is the weekly skim. Open your statement, run your eye down it, and ask one question: "Any surprises?" That's it. No categories, no maths. The surprises are the signal.
Why weekly beats monthly
A month is long enough to forget and long enough for a small habit to become a large bill. A week is short enough that the ₹2,000 you spent on food delivery still feels recent enough to change next week. Frequency, not detail, is what makes tracking stick. Run any version for two months and something shifts: you start making the decision before the spend, not after. That's the whole point. The tracking was never the goal; the changed decision is.
