Definition of Marginal Profit
Marginal Profit is the profit gained by a firm or individual from producing and selling one additional unit of a product or service. It takes into account the marginal revenue (additional revenue from selling one more unit) minus the marginal cost (the additional cost incurred to produce that unit). In simpler terms, it explains whether that extra burger will make you richer or leave you with a side of regret 👀.
\[
\text{Marginal Profit} = \text{Marginal Revenue} - \text{Marginal Cost}
\]

Examples
-
Example 1: A lemonade stand sells one more cup of lemonade for $2 (Marginal Revenue) while incurring an additional cost of $1 for the cup and lemons (Marginal Cost). The Marginal Profit would thus be:
\[
\text{Marginal Profit} = 2 - 1 = 1 \text{ dollar}
\]
-
Example 2: If producing a toy costs $10 (Marginal Cost) but sells for $8 (Marginal Revenue), the outcome is:
\[
\text{Marginal Profit} = 8 - 10 = -2 \text{ dollars (Marginal Loss)}
\]
- Marginal Revenue: The additional revenue generated from the sale of one more unit.
- Marginal Cost: The additional expense incurred from the production of one more unit.
- Total Profit: The overall earnings minus the total expenses for all units produced.
