The rejected option is part of the decision
Every commitment of money, time or attention spends something that could have gone elsewhere. The value of the best alternative you give up is the opportunity cost of your choice. It never appears on an invoice, which is exactly why it is so often left out.
What is seen and what is not seen
In 1850 the French economist Frédéric Bastiat wrote an essay built on a broken shop window. Everyone could see the glazier being paid for the repair. Nobody saw the pair of shoes the shopkeeper would have bought with the same money, because that purchase never happened.
Business decisions carry the same blind spot. The project you fund stays visible for years. The project you starved of the same people and budget leaves no trace, so it never gets a chance to argue its case.
Name an alternative you could really take
Opportunity cost is measured against the best option actually available, never against a dream. If the alternative to a new product line is a business you have neither the people nor the cash to build, it is no real rival, and comparing against it flatters whatever you choose.
A good test is whether the alternative could start next month with the resources this choice would consume. Very often the strongest rival is plain: improve what already sells, pay down expensive debt, or wait and keep the cash.
Price time and attention, not only money
Capital is the easiest cost to count and often not the scarcest. A founder's attention, a key engineer's next six months, or a sales team's focus for a quarter may be the true limit. A choice that looks cheap in cash can be the most expensive one on the table once those are counted.
Write each option's draw on the scarce resource next to its cash cost. The comparison often changes when the missing column appears.
Keeping the alternative in the room
Argumont gives each option its own Champion, so the path you are leaning away from still has someone making its strongest case. The Strategist looks for a materially different path, which is often where the overlooked alternative sits. The Grandfather asks what cannot be undone and what the cheapest way back would be. The Verdict names which option leads and what it would take to change that, and the Human Decision, recorded separately, is yours.
A second product or a better first one
A software firm has $400,000 and two engineers for six months. Option one builds a second product, forecast to earn $150,000 in its first year. Option two spends the same team improving the checkout of the existing product, where a 2 percent lift in sales on $3 million a year adds about $60,000, starting within weeks and repeating every year after. Counted against each other, the second product's lead is real but narrower than the pitch suggested, and it depends on a forecast, while the checkout gain rests on traffic the firm already has.
Questions
- Is opportunity cost the same as sunk cost?
- They point in opposite directions. Sunk cost is money already spent, which should not sway the choice ahead. Opportunity cost is value you are about to give up, which should.
- How do I estimate the value of an option I will not take?
- With the same care you give the one you will take. Use its realistic cost, its realistic return and its realistic timing. A rough honest figure is far more useful than leaving the line blank.
- Is doing nothing ever the best alternative?
- Often. Keeping cash, waiting for information or holding a team steady has real value, and a new commitment should beat it clearly before you give it up.
