The Latte Factor: Small Expenses, Massive Impact

Small daily expenses can cost you hundreds of thousands over time.

The Latte Factor refers to the idea that seemingly insignificant daily purchases, when compounded over decades, can significantly reduce your long-term wealth.

The Math

A $5 daily coffee habit over 30 years, assuming 7% average annual returns, can cost you over $175,000 in opportunity cost.

This is why tracking and optimizing small recurring expenses is one of the highest-leverage habits in early retirement planning.
