Question 1

What is the Latte Factor?

Accepted Answer

Coined by author David Bach, the Latte Factor is the idea that small daily expenses (like a $5 latte) compound into massive amounts over time. A $5/day habit costs $1,825/year — invested at 10% for 30 years, that becomes over $330,000.

Question 2

Does the Latte Factor really work?

Accepted Answer

Mathematically, yes — compound interest makes small daily savings significant over decades. Critics argue that cutting small pleasures is psychologically difficult and that larger expenses (housing, cars) have more impact. The truth: both matter, but awareness of daily spending is the first step.

Question 3

How much does a daily coffee habit cost per year?

Accepted Answer

At $5.50/day (average specialty coffee), that's $2,008/year. Over 10 years: $20,075. If invested at 10% annual return instead, you'd have $34,800 after 10 years or $373,000 after 30 years.

Question 4

What's a good investment return rate to use?

Accepted Answer

The S&P 500 has averaged ~10% per year historically (before inflation). A more conservative estimate is 7% (after inflation). Use 7-10% for long-term projections. For savings accounts, use 4-5%.
