Convert Expenses to Savings

This calculator shows what a small daily discretionary expense could grow to if you invested it instead, illustrating the long-run opportunity cost of everyday spending.

The latte-factor idea

Small, regular expenses feel trivial day to day, but invested over decades they compound into meaningful sums. Redirecting even a few dollars a day to investing can grow into tens of thousands, which is why habitual spending has a real long-term cost, and why automating savings pays off.

Balance, not deprivation

The point isn't to cut every small pleasure, it's to see the trade-off clearly and choose deliberately. Trimming a habit you don't value much and investing the difference can quietly build wealth without feeling like sacrifice. Use the figure as motivation to automate, not as a rule to never enjoy anything.

How to use it

  1. Enter a daily discretionary amount.
  2. Set an expected annual return.
  3. Set the number of years.
  4. See what investing it instead could grow to.

Frequently asked questions

How much can small daily spending add up to?

Invested over decades, a few dollars a day can grow into tens of thousands, because the contributions compound over time. Enter your numbers to see.

Should I cut all small expenses?

No, the goal is to spend deliberately. Trim habits you don't value much and invest the difference, rather than depriving yourself of everything.

What return should I assume?

For long-term investing, a diversified portfolio has historically returned in the mid-single digits to around 7% before inflation. A conservative figure avoids overestimating.
