Latte Factor Calculator: The Shocking Truth About Your $5 Coffee
📅 Last Updated: January 23, 2026 | 📖 5 min read
📑 Quick Navigation:
That $5 coffee isn’t just $5. It is $5 plus 30 years of lost investment growth. This concept is famously known as the “Latte Factor,” and ignoring it is the number one reason most middle-class earners never reach financial freedom.
When you spend money on small daily habits—like a $5 latte, a $15 streaming subscription, or a $20 Uber Eats order—you aren’t just losing the cash. You are destroying the Compound Interest that cash would have earned if you had invested it instead. Our Latte Factor Calculator reveals the brutal math behind your spending habits.
💡 Key Takeaway
Your $5 daily coffee costs you $339,073 over 30 years. That’s not an exaggeration—it’s compound interest math. Every small expense you eliminate and invest instead becomes exponential wealth. The Latte Factor isn’t about deprivation; it’s about understanding the true cost of unconscious spending.
⚠️ The “Latte Factor” Math
Let’s run the numbers. If you spend $5/day on coffee, that is $150/month. If you invested that $150 into the S&P 500 (assuming a 10% average return) instead of drinking it, here is what happens:
- 10 Years: $30,727
- 20 Years: $113,905
- 30 Years: $339,073
You didn’t drink a $5 coffee. You effectively drank a Ferrari.

The “Rule of 752”: A Mental Shortcut
You don’t always need a Latte Factor Calculator handy. There is a famous mental math trick called the “Rule of 752,” popularized by the financial independence community.
To find the 10-year value of a weekly expense, multiply it by 752. For example, a $20 weekly pizza habit is worth $15,040 ($20 x 752) invested over a decade.
Understanding this math changes your psychology. Every time you buy a liability (something that loses value), you pay twice:
- The Purchase Price: The money leaves your pocket instantly.
- The Future Growth: That dollar can never work for you again.

How to Fix Your Finances
This calculator isn’t meant to make you miserable or stop you from enjoying life. It is meant to make you conscious. If the coffee brings you $300,000 worth of happiness, buy it. But if it’s just a mindless habit, cut it.
The solution is to automate your “Wealth Tax” first. Before you spend, send a fixed amount to your investment accounts. If you use a tool like our DCA Calculator, you can see how consistent investing protects your future better than saving pennies.

Latte Factor FAQ
What is the Latte Factor?
The “Latte Factor” is a concept popularized by author David Bach. It illustrates how small, daily discretionary spending (like a coffee) adds up to massive lost wealth over time due to the power of compound interest.
How does the Latte Factor Calculator work?
Our Latte Factor Calculator takes your daily spend, annualized it, and applies a compound interest formula (usually 7-10%) over a set timeframe. This shows you the “Opportunity Cost” of that spending.
Does small spending really matter?
Yes. Because of compound interest, small sums over long periods become massive. Investing just $10/day at 10% returns turns into over $600,000 in 30 years. Using a Latte Factor Calculator helps visualize this impact.
