Here's how to find marginal cost: divide the total change in production costs with additional production by the change in the overall quantity (that is, how many more things you are producing).

Marginal Cost Formula

The marginal cost formula described above is summed up as follows:
Marginal Cost = (Change in Cost) / (Change in Quantity)
What do we mean by "change in cost" and "change in quantity"?

Costs of production (which include fixed costs as well as variable costs) increase with more production because producing more units means buying more raw materials and/or hiring more workers. The change in cost is equal to production cost from levels of output prior to the increase in production subtracted from the cost from levels of output following the increase in production.

Meanwhile, change in quantity is simply the increase in levels of production by number of units. That is, subtract the quantity from before the increase in production from the quantity from after the increase in production-that will give you the change in quantity.

Example of Calculating Marginal Cost

Let's say there's a small company called ABC Wallets that produces 5,000 high-quality, artisanal leather wallets every year. Every year, this level of production costs them $250,000-these are their production costs.

At some point, though, the word gets out about how great their wallets are, and more people want to buy them, so there is very high demand for them. ABC Wallets' owners decide to produce more wallets every year, increasing their total annual production to 10,000 wallets.

Although they do have to hire more workers, and also purchase better and more efficient tools and machinery (the cost of which is not accounted for in this example, for the sake of simplicity, although in the real world it of course should be), they find that their production costs per unit decrease. At this point, they're producing twice as many wallets for just $375,000 that year.

To find the marginal cost of each additional wallet produced, let's plug this example into the formula above:
Marginal Cost = $125,000 / 5,000
This means that the marginal cost of each additional unit produced is $25.

One can calculate total revenue by multiplying the price per product by the total number of units of that product that were sold. Here's how that equation looks:
P x Q = TR
"P" refers to the price per unit of that product, while "Q" refers to the quantity sold during the period you're calculating for. "TR" means total revenue.

Finding your profit

Once you have the total revenue, as long as you know your total cost as well, you can find the profit. In order to find that number, subtract the total cost from your total revenue. The equation for that looks like this:
Profit = TR - TC
Relationship between "P" and "Q"

In a perfectly competitive market, P is a constant, and Q does not affect it. However, most markets are imperfectly competitive. In an imperfectly competitive market, P has an inverse relationship with Q.

In an imperfectly competitive market, too, price is controlled by the firm; in order to sell higher quantities of the product, its price must decrease. Additionally, whatever kind of market you're looking at, the total revenue is a function of Q.

In the field of economics, the term "average variable cost" describes the variable cost for each unit. Variable costs are those that vary with changes in output. Examples of variable costs, otherwise known as direct costs, include some forms of labor costs, raw materials, fuel, etc. This is in contrast to fixed costs, or overheads, which are not affected by output; examples of such costs include rent, insurance, and so forth. The average variable cost is equal to the total variable cost divided by the output.

Fixed costs and variable costs determine the total cost.

Marginal cost, average (fixed, variable, and total) cost, total cost, and total variable cost change as total output changes, but total fixed cost remains constant at all output levels, including zero output.

Production functions with diminishing marginal returns yield an upward-sloping marginal cost curve.

Specialization and the division of labor reduce marginal costs for firms.

Cost curves can shift in response to changes in input costs and productivity.
