Use Cases
Compare investment options
Evaluate whether your current investment is performing better than the best alternative you could have chosen.
Example: If your stock returned 8% and the best alternative bond returned 5%, opportunity cost is -3% (you gained 3% more).
Assess business decisions
Use the calculator to weigh the financial return of a business project against the next best use of your capital.
Example: A project returns 12% while the best alternative is 10%, so opportunity cost is -2%.
Frequently Asked Questions
- What is opportunity cost?
- Opportunity cost is the value of the next best alternative you give up when making a decision. In finance, it's the return you could have earned from the best alternative investment compared to the one you chose.
- How is opportunity cost calculated?
- The calculator subtracts the return of your chosen option from the return of the best alternative. The result is the percentage of return you forgo by not choosing the alternative.
- Can opportunity cost be negative?
- Yes, if your chosen option's return is higher than the best alternative, the opportunity cost is negative, meaning you made a better choice than the alternative.
Tips & Common Mistakes
Tips
- Ensure you use the same time period for both returns to get an accurate comparison.
- Consider all potential alternatives, not just the most obvious one, to find the true best alternative.
- Use the calculator to quickly see if your chosen option is outperforming the alternative by a significant margin.
- Remember that opportunity cost is just one factor; consider risk and liquidity as well.
Common Mistakes to Avoid
- Using different time periods for the returns, which skews the comparison.
- Forgetting to include all relevant alternatives, leading to an inaccurate best alternative return.
- Confusing opportunity cost with actual loss; it's a measure of forgone potential, not a direct financial loss.
