The Latte Factor: Why Small Habits Have Massive Consequences

Financial author David Bach popularized the concept of the "Latte Factor" — the idea that small, recurring daily expenses quietly drain your wealth over a lifetime. The math is brutally simple: a $5 coffee every workday adds up to over $1,300 a year. Invested in an index fund at historical market returns, that money compounds into something extraordinary.

It's Not About Deprivation — It's About Awareness

The goal of this calculator isn't to guilt you into giving up your morning ritual. It's to make the invisible visible. Most people genuinely don't know what their daily habits cost them in terms of future wealth. Once you see the number, you can make a conscious choice — and that's true financial freedom.

🧠 The Psychology of Compound Interest: The human brain is notoriously bad at imagining exponential growth. We think linearly — "$5 a day is $150 a month." But compound interest doesn't think linearly. It snowballs. That's why the results of this calculator tend to shock people.

What the Numbers Mean in Real Life

Consider that the median American retirement savings is around $87,000. A single daily coffee habit, redirected into the market starting at age 25, can produce over $250,000 by retirement. That's not a financial plan — it's a mindset shift about the value of every dollar today versus tomorrow.
