Opportunity Cost Calculator
Every choice has a cost — the best alternative you didn't take. See what your daily habits could become if invested instead. The math will surprise you.
Where this fits
This tool lives inside Cash Flow and is most useful for households.
The core idea: Every financial choice has an opportunity cost �� the value of the best alternative you didn't take. That daily coffee isn't just $5. It's whatever that $5 could have grown to over decades. This calculator makes that trade-off visible.
