What is the Difference Between Surplus and Profit?

🆚 Go to Comparative Table 🆚

The difference between surplus and profit lies in the costs they consider. Surplus is the revenue from the sale of an item minus the marginal, direct cost of producing that item, while profit is the total revenue minus the total costs, including fixed or sunk costs that do not change regardless of the number of items produced.

Here are the key differences between surplus and profit:

  1. Cost Considerations: Surplus considers only the marginal, direct costs of production, while profit takes into account both fixed and variable costs.
  2. Calculation: Surplus is calculated as the sales price minus the minimum price a seller would accept (marginal cost of production), while profit is calculated by subtracting all expenses (including fixed costs) from the total income.
  3. Financial Implications: Profit is the return that business owners obtain for bearing the risks and costs of running their businesses, while surplus is the excess income made by a not-for-profit organization.

In summary, surplus focuses on the revenue generated from selling a product or service minus the marginal, direct costs of production, while profit considers the total revenue minus all costs, including fixed and variable costs. Surplus is more relevant for not-for-profit organizations, while profit is crucial for businesses to evaluate their financial performance and return on investment.

Comparative Table: Surplus vs Profit

The difference between surplus and profit can be understood through the following table:

Surplus Profit
Surplus refers to the amount remaining after all costs, both fixed and variable, have been deducted from the total revenue. It is the excess of supply over demand at a given price. Profit is the revenue earned after subtracting all costs, including fixed and variable costs, from the total revenue. Profit is an indicator of the efficiency and financial stability of a company.
There are two types of surplus: producer surplus and consumer surplus. Producer surplus is the difference between the price a product is sold for and the price at which it is produced, while consumer surplus is the difference between what a consumer is willing to pay and the actual price they paid. Profit can be calculated using accounting methods or economic methods, with accounting profit ignoring opportunity costs and economic profit considering opportunity costs, which include implicit costs.
A surplus can occur when there is more of a product than is needed, leading to a disconnect between supply and demand that can sometimes cause financial losses or wasted resources. A deficit occurs when expenses exceed revenues, resulting in a negative balance. When a company's profits consistently fall short of covering the costs of production and the opportunity costs associated with operating the business, the business will eventually fail for lack of revenue completion.

In summary, surplus is the remaining amount after all costs have been deducted from the total revenue, while profit is the revenue earned after considering all costs, including fixed and variable costs. Profit is an indicator of the efficiency and financial stability of a company, whereas surplus can be a temporary state that does not necessarily affect the overall financial health of a business.
