Examples of opportunity cost in different contexts

Opportunity cost is the value of the next best alternative you give up when you make a choice. It’s the “cost” of not choosing the best alternative that you could have taken.

In formula form: $C_{op} = \text{value of next best alternative}$

Imagine you have £50 to spend on a weekend:

• Option A: Buy a new video game for £30.
• Option B: Go to a cinema for £25.
• Option C: Save the money for a future trip.

If you choose the video game, the opportunity cost is the enjoyment you would have had at the cinema (and the future savings you would have made). In symbols: $C_{op} = \text{cinema experience} + \text{future savings}$

A factory can produce either:

1. 10 units of Product X at a cost of £5,000.
2. 8 units of Product Y at a cost of £4,000.

If the factory chooses Product X, the opportunity cost is the profit that could have been earned from producing Product Y. Calculated as: $C_{op} = \text{Profit from Y} - \text{Profit from X}$

A government can allocate its budget to:

• Education: £2 billion.
• Healthcare: £1.5 billion.
• Infrastructure: £1 billion.

Choosing to spend more on education means the opportunity cost is the reduced spending on healthcare and infrastructure. In economic terms: $C_{op} = \text{Healthcare + Infrastructure benefits lost}$

1. Define opportunity cost clearly. Use the formula $C_{op} = \text{value of next best alternative}$ in your answer.

2. Use real‑world examples. Relate the concept to personal, business, or government decisions to show understanding.

3. Show the trade‑off. Explain what is given up and why it matters.

4. Keep it concise. Aim for 3–4 sentences per example.

Good luck, and remember: every choice has a cost! 🚀
