What is Opportunity Cost?
Opportunity cost refers to the potential benefit you miss out on when choosing one alternative over another. In simple terms, it's the value of what you’re giving up by making a particular financial decision.
Let’s say you're deciding whether to buy a car or invest the same amount of money. If you choose the car, the opportunity cost is the interest and returns you could have earned by investing. This calculator is designed to help you figure out that difference — the true cost of your choice.
How to Calculate Opportunity Cost
To estimate opportunity cost accurately, you need to provide the following details:
- Investment Amount: The amount of money you are considering to spend or invest.
- Expected Rate of Return: The annual percentage return you expect from the investment.
- Investment Duration: The number of years you plan to keep the investment.
- Capital Gains Tax Rate: The percentage of your earnings that will be taxed after the investment period.
- Annual Inflation Rate: The yearly rate at which the cost of living increases, reducing purchasing power.
Once you enter this information into the calculator, it will instantly display how much money you could potentially earn if you invest instead of spending — that’s your opportunity cost.
Example Scenario
Suppose you have $20,000 and you're torn between buying a new car or investing the amount at a 6% annual return over 5 years. After factoring in capital gains tax and inflation, the opportunity cost might be several thousand dollars — money that could grow your future savings or be used for a better purchase later on.

Formulas in Play
Basic Method
Opportunity Cost = FO – CO
PPC-based Method
Opportunity Cost (slope formula) = (Y₁ – Y₂) ÷ (X₂ – X₁)
Investment Method
Total Savings (After Tax) = (MoneyToSpend * (1 + AnnualReturn/100)^Period) * (1 - IncomeTax/100)
Inflation-Adjusted Opportunity Cost = TotalSavings - (MoneyToSpend * (1 + InflationRate/100)^Period)
Table-based Method
Opportunity Cost = Option2 – Option1
Sample Table & Example
| Scenario | Input Example | Result |
|---|---|---|
| Basic Method | FO = 10,000; CO = 7,500 | 2,500 |
| PPC Method | (X₁=5,Y₁=10), (X₂=3,Y₂=13) | 1.5 |
| Investment Method | Money = 1000, Return = 3%, Period = 1yr, Tax = 12%, Inflation = 2.5% | Savings: 911.36; Cost: 10.22 |
| Table Method | Option 1 = 2,000; Option 2 = 3,500 | 1,500 |
User Guide
This calculator is designed to make it easy to understand and calculate opportunity cost using three distinct methods. **Section A** is the most straightforward, using the classic formula of subtracting your chosen option's return from the best alternative's return. Simply enter the two numerical values and click "CALCULATE" to see the result displayed below. This method is ideal for quick financial decisions where you have a clear understanding of the returns on two specific options.
For a more visual and in-depth analysis, **Section B** uses a Production Possibility Curve (PPC). You can calculate the opportunity cost by entering two sets of coordinates (X₁, Y₁) and (X₂, Y₂) from your PPC graph. The calculator will determine the slope, which represents the opportunity cost, and plot these points on an interactive graph to help you visualize the trade-off. Finally, **Section D** is for situations where you simply need to find the difference between two options presented in a table or list format. Enter the two values, and the tool will calculate the difference, helping you quickly assess the cost of choosing one over the other.
FAQs
Q1: How do I calculate opportunity cost?
Use the formula FO – CO. If you know returns of two options, subtract the chosen option’s return from the best alternative’s return.
Q2: How to determine the opportunity cost using a PPC?
Calculate the slope between two points on the PPC using `(Y₁ – Y₂) ÷ (X₂ – X₁)`. This shows how much of one good must be forgone for additional units of another.
Q3: How to find opportunity cost from a table?
Simply input the two values in the table tool to get a clear numerical difference representing the opportunity cost.
Q4: How to compute for opportunity cost in decision-making?
Compare the returns or benefits of two options and subtract to know what you're giving up—critical for efficient choices.
Q5: How do you calculate opportunity cost using a PPC graph?
The slope of the PPC visually shows the trade-off rate—enter coordinate data into our PPC section to calculate it precisely.
