Zero dependency · Works offlineOpportunity cost is the potential gain you give up by choosing one investment over another. For example: putting $50,000 in a 4% savings account instead of an 8% index fund — the 10-year opportunity cost is the difference between the two outcomes. After adjusting for inflation and taxes, the real-world impact can be even more significant.
