Frequently asked questions
What is the Latte Factor? ▼
The Latte Factor is a concept popularized by David Bach suggesting that small, recurring daily expenses add up to a significant amount over time. If invested instead, they could compound into substantial wealth.
How much does a $5 daily coffee cost over 30 years? ▼
A $5 daily coffee costs about $1,825 per year, or $54,750 over 30 years in cash. If invested at 7% annual returns, it would grow to approximately $184,000 over 30 years.
Should I really cut my daily coffee? ▼
The latte factor is a thought experiment about opportunity cost, not a strict prescription. The goal is awareness — understanding that small recurring costs have a large long-term impact. What you choose to cut (if anything) is personal.
Does the latte factor mean I should never spend on enjoyment? ▼
No. Personal finance is about balance. The latte factor raises awareness about recurring costs and their compound effect — it doesn't advocate deprivation. Even redirecting 20–30% of a habit's cost into savings can make a meaningful difference over decades.
How much would $10/day grow to over 30 years? ▼
At 7% annual return, $10 invested every day for 30 years would grow to approximately $368,000. At $20/day, that's roughly $736,000. The compounding effect makes even small daily commitments transformative over time.
