The cost of your siege bot factory is a fixed cost, the cost of producing siege bots is a variable cost. The total cost of your siege bot is the price of your siege bot in addition to the price of your siege bot factory divided by the number of siege bots produced. Therefore, the more siege bots you build, the less each siege bot costs.
siege bot cost = siege bot price + (price of factory / total siege bots produced)
For example: the price of a t3 land factory is equal to the price of nine siege bots; therefore, if you build nine siege bots, each siege bot’s cost is in fact twice it’s listed price. If you build eighteen siege bots, then the cost of each siege bot will be 25% lower than if you had only built nine.
The true cost of your siege bots will always be higher than the listed price.
The more siege bots you build, the less they all cost, including the ones that have already been built. Production capacity is very important, but keep total costs and variable costs in mind; the more factories you build, the more each siege bot costs. Review Psalm 30 to read more about production capacity.
