If Invested (compounding)
How this works: Each year you'd save your annual habit cost and invest it. The "If Invested" line shows the compounding future value using the annuity formula FV = PMT × ((1 + r)ⁿ − 1) / r, where PMT = annual spend, r = expected return, n = years to retirement. Assumes end-of-year contributions. Adjust the return rate in the Calculator tab.

Annual Cost Breakdown

HOW TO USE

01

Enter Your Habit

Name your habit, set the cost per instance and how many times per week you indulge. Use a preset for common habits like daily coffee or a weekly restaurant meal.

02

Set Your Timeline

Enter your current and retirement ages and an expected investment return (7% is the standard inflation-adjusted S&P 500 average). Your hourly wage unlocks the "work hours" stat.

03

Explore the Impact

See the full picture — weekly through lifetime costs, work hours spent earning that money, and the opportunity cost if you invested instead. Add more habits in the Multi-Habit Tracker.

FREQUENTLY ASKED QUESTIONS

What is the latte factor?

The latte factor is the idea that small, recurring daily expenses add up to surprising totals over time. A $6 coffee 5 days a week costs $1,560 per year — and over $54,000 in 35 years. Invested at 7%, that same money could become over $235,000.

How is the annual habit cost calculated?

Annual cost = cost per instance × times per week × 52 weeks. For example, a $6 coffee 5 times per week: $6 × 5 × 52 = $1,560 per year.

How is the "if invested" future value calculated?

Using the annuity future value formula: FV = PMT × ((1 + r)ⁿ − 1) / r, where PMT is your annual habit cost, r is the expected annual return rate, and n is years until retirement. This assumes end-of-year contributions that compound over time.

What investment return rate should I use?

The historical S&P 500 average is ~10% before inflation, or ~7% after. Use 7% as a realistic, inflation-adjusted estimate. Adjust it up or down based on your investment mix and risk tolerance.

Should I quit every daily habit to save money?

Not necessarily. The goal is awareness, not deprivation. Some habits bring genuine value — social connection, health, enjoyment. Understanding the true cost helps you make intentional choices rather than accidental ones.

What does "opportunity gain %" mean?

It shows how much more wealth you'd have from investing vs. simply spending. If your lifetime spend is $54K and the invested future value is $235K, the opportunity gain is +330% — meaning you'd end up with 4.3× more by investing instead.
