Latte Factor
The concept that small, habitual daily discretionary expenses compound over time into significant wealth-building opportunity costs.
What is Latte Factor?
The latte factor, coined by financial author David Bach, describes the cumulative financial impact of small recurring discretionary purchases — such as daily coffee, snacks, streaming subscriptions, or convenience fees — that individually seem trivial but collectively represent significant money that could alternatively be saved and compounded over time. The math is compelling: $5 per day invested at a 7% annual return grows to approximately $7,000 in 5 years and $95,000 in 30 years. Critics argue the concept oversimplifies wealth inequality and distracts from structural financial issues, while proponents say it illustrates the power of compound interest and conscious spending. The term has evolved into a broader shorthand for any category of small, habitual spending that accumulates unconsciously.
Example
A 25-year-old who buys a $6 coffee every weekday ($120/month) and redirects that money to a Roth IRA invested in a broad index fund instead, assuming 7% annual returns, would accumulate approximately $142,000 by age 65. The same person who also redirects a $15/month streaming subscription would add another $18,000. Total: $160,000 from two 'small' daily habits — illustrating how the latte factor combines dollar-cost averaging with compound interest.
