When studying finance or economic, the cost of a decision is also known as an "opportunity cost".
Opportunity cost is a financial aspects term that alludes to the estimation of what you need to surrender with the end goal to pick something different. More or less, it's an estimation of the street not taken.
The idea behind opportunity cost is that, as an entrepreneur, your assets are constantly constrained. That is, you have a limited measure of time, cash, and skill, so you can't exploit each opportunity that goes along. On the off chance that you pick one, you fundamentally need to abandon others. They are totally unrelated. The estimation of those others is your opportunity cost.
