Habit Cost Calculator
The habit cost calculator helps you discover how much regular routines and small everyday purchases actually cost. Takeaway coffee, snacks, food delivery, smoking, and unused subscriptions seem cheap day-to-day, but accumulate into substantial sums over time.
How to use
- Enter the cost of a single purchase or action.
- Input the frequency (times per day or per week).
- Set an expected investment return rate if you invested that money.
- Review total expenses across monthly, 1-year, 5-year, and 10-year horizons.
- See how much wealth you could build using compound interest.
The Power of the Latte Factor
Popularized by financial author David Bach, the 'Latte Factor' highlights how small, mindless daily micro-expenses quietly drain significant investment capital over decades.
Sample Calculation: Daily Coffee
Buying a $4 coffee 5 days a week equals $20/week, ~$87/month, and $1,040/year. Invested at an 8% annual return over 10 years, that routine grows into roughly $16,000.
