I had a creeping sense that I was leaking money on small purchases that did not bring me much value. The Amazon impulse buys. The "I deserve this" coffees. The books I would never read.
For 30 days I bought nothing optional. Tracked what I would have bought, what I missed, and what I learned. Here is the report.
The setup
Rules:
- For 30 days, $0 spent on non-essentials
- Essentials = food/groceries, gas, household necessities, pre-existing bills, medical needs
- Non-essentials = restaurants, coffee out, alcohol, entertainment, clothing, books, gadgets, anything optional
- Tracked every "I want to buy this" impulse, whether I actually would have, and what happened
Week 1: discovery
The first week was an education in how often I impulsively reach for purchases. I logged 23 "I want to buy this" moments in 7 days. About 3 per day.
What I would have bought:
- 4 coffees out
- 2 lunches out
- 1 dinner out
- 3 random Amazon items (chargers, organizing bins, "useful" gadgets)
- 2 books
- 2 apps/digital services
- 1 clothing item
- Various small "treats" (snacks, drinks, etc.)
Estimated dollar value: about $185 in week 1 alone.
I had to actively talk myself out of each purchase. The default reach for the wallet was constant.
Week 2: noticing patterns
By week 2, I started noticing what triggered the purchase impulses:
Boredom: The biggest trigger. When I was bored, my brain would suggest "let me look at Amazon" or "let me grab a coffee." This was about distraction, not actual want.
Stress: Stressful day → impulse to "treat" myself. The treats were mostly food and small purchases.
Social context: When friends suggested coffee or lunch out, I would reflexively say yes without actually wanting it.
Algorithm-served: Ads for things I had been thinking about, items recommended after browsing. These felt urgent in the moment but mostly were not.
Week 3-4: stabilizing
By week 3, the impulse frequency dropped from 3/day to maybe 1/day. Some of this was the "novelty wore off" effect — without ever buying anything, the impulses started feeling silly.
I started doing other things in moments where I would have bought something:
- Bored at home → read a book I already owned instead of buying a new one
- Wanted coffee → made coffee at home
- Wanted to "treat" myself → went for a walk instead
- Friends suggested lunch out → suggested cooking together instead
The substitutes were not always equal but they were rarely worse.
End-of-experiment numbers
- Total impulses logged: 67
- Impulses where I would have bought something: 52
- Estimated total avoided spending: $612
- Things I genuinely missed: 3 (a specific book, dinner out with a friend, a coffee with a coworker)
- Things I did not miss at all: the other 49
What surprised me
1. The amount. $612 in 30 days of "small" spending. That is over $7,000 per year on stuff I would not have missed.
2. How few things I actually missed. Of 52 avoided purchases, only 3 felt like genuine losses. The other 49 were impulses that the moment passed and I never thought about again.
3. The boredom revelation. A huge percentage of my spending was about killing time or treating moods rather than buying things I wanted.
4. The social spending. A large portion of "discretionary spending" was actually social spending I had not flagged. Coffee with friends. Lunches out. Drinks. Some of this is socially valuable; much of it was inertia.
What I added back
After the 30 days ended, I did NOT return to my previous spending pattern. I added things back selectively.
What I added back:
- One nice coffee out per week (was 4-5)
- One restaurant meal per week (was 3-4)
- Books I had specifically wanted, not impulse books (was lots of impulse books)
- The few digital services I actually used (was several I did not)
What I did not add back:
- Random Amazon impulse purchases
- "Treat" snacks and drinks at convenience stores
- The smaller "I deserve this" purchases that had been almost daily
- Most clothing purchases (still buying when actually needed, not impulsively)
The math one year later
I have been tracking discretionary spending for the year since the experiment. Estimated annual reduction in non-essential spending: about $4,800.
This was not from cutting things I valued. It was from cutting things I had been buying without valuing.
What I learned about money
1. Most "small" spending is invisible until tracked. $5 here, $15 there, adds up to thousands per year. Nobody decides to spend $7,000 on impulse items. It happens $5 at a time.
2. The thing you buy is rarely the thing you wanted. Most impulse purchases are about the moment you are in (bored, stressed, social pressure) rather than about the actual item.
3. Pausing changes outcomes. Even a 24-hour delay between "want to buy" and "buy" eliminates 70%+ of impulse purchases.
4. Substitutes work. The thing you would have bought rarely produces the satisfaction you expected. Other activities (reading, walking, calling someone) often do.
This is not advice
If you are not in a financial position where this kind of optimization matters, ignore me. Some people's discretionary spending is meaningful joy. Some is just leakage. The experiment helps you tell the difference for your specific situation.
The takeaway
The "I do not have money" feeling and the "I have lots of small leakage" reality are often the same situation. Most of us are spending substantial money on things we would not miss if they were gone.
Run the experiment for 30 days. Track every avoided purchase. You will be shocked by the total. You will be more shocked by how few things you genuinely missed.
Then add back only what you valued. Keep the savings.
