I've tried to track my expenses before. Spreadsheets, apps, even a notebook. I've never lasted more than two weeks.
This time I committed to 30 days using Justlog — logging every single expense, no matter how small. A ₹20 bun maska at the chai stall. A ₹5 parking ticket. Everything.
Here's what happened.
The setup
I used Justlog because logging is fast enough that I'd actually do it. I created three spaces:
- Personal — everyday expenses
- Work — anything reimbursable
- Home — shared household expenses
The rule was simple: log within 5 minutes of spending. No batching, no "I'll do it later."
Week 1: The discomfort
The first week was uncomfortable. Not because tracking was hard — Justlog makes it genuinely fast — but because I could suddenly see everything.
Day 3, I realised I'd spent ₹840 on coffee in three days. Three days. That's not unusual for me, but I'd never seen it written down before.
Day 5, I found two subscriptions I'd completely forgotten about. A fitness app I hadn't opened in four months (₹299/month) and a news app I'd subscribed to during a free trial (₹149/month). Cancelled both.
Week 1 total: ₹14,200
That number shocked me. I had vaguely assumed I spent around ₹8,000-9,000 in a normal week. I was wrong by nearly ₹6,000.
Week 2: The patterns emerge
By week two, the Story screen in Justlog started showing me patterns I couldn't unsee.
Food & Drinks: 41% of total spending.
Nearly half my money was going to food — and most of it wasn't groceries. It was restaurants, cafes, Swiggy, Zomato. I wasn't eating badly, I was just eating expensively.
I didn't change anything yet. The rule for the first two weeks was just to observe.
Transport: 18%
More Uber/Ola than I thought. Mostly short trips I could have walked or taken an auto for.
The invisible expenses
The most surprising category was what I called "invisible expenses" — things I paid for without thinking. Convenience fees, platform charges, delivery fees. Individually tiny. Collectively significant.
₹1,200 in delivery fees alone over two weeks. For food that would have been cheaper to pick up.
Week 3: Small changes, visible results
In week three I made three small changes based on what I'd seen:
1. Cook breakfast at home instead of buying it. Saved ~₹200/day. 2. Take auto instead of Uber for trips under 5km. Saved ~₹150/trip. 3. No food delivery on weekdays unless I genuinely had no time.
I didn't deprive myself of anything. I just made slightly different choices with full awareness of what they cost.
Week 3 total: ₹9,800. Down ₹4,400 from week 1 with no feeling of sacrifice.
Week 4: The new normal
By week four, logging had become automatic. I'd open Justlog before I'd even put my wallet away. The habit had formed.
The numbers kept improving — not because I was being strict, but because awareness changed my default choices. I started asking "is this worth it?" instead of spending on autopilot.
Week 4 total: ₹8,600.
The 30-day summary
| Category | Month Total | % of Spending |
|----------|-------------|---------------|
| Food & Drinks | ₹18,400 | 38% |
| Groceries | ₹6,200 | 13% |
| Transport | ₹7,800 | 16% |
| Bills & Subscriptions | ₹3,200 | 7% |
| Shopping | ₹5,600 | 12% |
| Other | ₹6,800 | 14% |
Total: ₹48,000
Versus my vague mental estimate of "around ₹30,000 a month."
The gap between what I thought I spent and what I actually spent was ₹18,000. Every month. That's ₹2.16 lakh a year disappearing without me noticing.
What I learned
1. Awareness is the intervention. I didn't need a budget. I didn't need willpower. I just needed to see the numbers. Seeing them changed my behaviour automatically.
2. Small expenses are the real leak. My big expenses (rent, EMIs) were always in my head. The money I was losing was in the ₹50-500 range — too small to remember individually, massive in aggregate.
3. The habit only forms if logging is frictionless. Previous attempts failed because the app was too slow or complex. With Justlog I could log in 5 seconds, which meant I actually did it.
4. Categories matter less than consistency. I didn't obsess over whether something was "Food" or "Groceries." I just logged it. The insights came from the total picture, not perfect categorisation.
Should you try it?
Yes. One month is enough to see patterns that will genuinely surprise you.
The rules are simple:
- Log every expense within 5 minutes of spending
- Don't change anything for the first two weeks — just observe
- After two weeks, make one small change based on what you see
