You might have learned about opportunity cost in GCSE business studies, and never thought of it again. This mundane term refers to the idea that when we choose to invest ourselves in something, there’s a natural flip side: the things we could have done instead, but now can’t. You spend your money on a holiday; the opportunity cost is that you can’t also afford that nice new shed you’d been looking at. If you choose crisps in your lunchtime supermarket meal deal, you can’t also have a KitKat.
