☕ Latte Factor Calculator

The Latte Factor is a financial principle showing that small daily expenses like coffee accumulate into huge sums over the years, especially considering the returns you could have earned if that money were invested in an index fund like the S&P 500.

Not necessarily. The goal is to understand the opportunity cost of daily expenses and make conscious decisions. You can find a balance between enjoyment and saving.

The calculator multiplies the daily cost by 365 days, then applies compound interest on the annual amount over the remaining years until retirement, based on the average annual return of your chosen investment index.

The S&P 500 (average ~10% annual return) is the most common benchmark for US investors. The Nasdaq tends to be more tech-heavy with higher volatility. Choose the index that best matches your investment strategy.

A $6 daily coffee is $2,160/year. Invested at 10% annual return for 30 years, that grows to over $400,000. That's the power of compound interest — your coffee habit could literally be costing you a retirement fund.

A pack-a-day habit at $10/day is $3,650/year. Over 25 years invested at 10%, that becomes over $360,000. Quitting smoking is one of the best financial and health decisions you can make.

Both matter, but cutting small expenses is something you can do today. $15/day on eating out is $5,475/year — which could grow to over $350,000 in 30 years if invested. Plus, saved money is tax-free, unlike additional income which gets taxed.

Compare your results to investing in a S&P 500 at ~10% annually. Use this as a baseline to evaluate your investment decision.
