Marginal Revenue Calculator
Marginal revenue is a fundamental concept in economics and business, representing the additional revenue generated from selling one more unit of a good or service. It helps businesses determine the optimal production level to maximize profits.
Understanding Marginal Revenue
Marginal revenue (MR) is the change in total revenue that results from selling one additional unit of output. It is a crucial metric for businesses when making decisions about production levels and pricing strategies. For instance, if a company sells 100 units for a total revenue of $1000, and then sells 101 units for a total revenue of $1005, the marginal revenue from the 101st unit is $5.
Formula for Marginal Revenue
The general formula for marginal revenue is:
MR = (Change in Total Revenue) / (Change in Quantity)
Or, more specifically:
MR = (Total Revenue at New Quantity - Total Revenue at Previous Quantity) / (New Quantity - Previous Quantity)
When the change in quantity is exactly one unit, the formula simplifies to:
MR = Total Revenue at New Quantity - Total Revenue at Previous Quantity
Why is Marginal Revenue Important?
- Profit Maximization: Businesses aim to produce at a level where marginal revenue equals marginal cost (MR = MC). Producing beyond this point would mean the cost of producing an additional unit exceeds the revenue it generates, leading to reduced profits.
- Pricing Decisions: Understanding how changes in quantity affect total revenue helps in setting optimal prices. In perfectly competitive markets, marginal revenue often equals the market price. In monopolistic or oligopolistic markets, marginal revenue is typically less than the price because to sell more units, the firm must lower the price for all units.
- Production Planning: It guides production managers on whether to increase or decrease output. If MR is greater than MC, increasing production will add to profits. If MR is less than MC, reducing production will save costs and increase profits.
Example Calculation
Let's say a company sells:
- Previous Quantity (Q1): 50 units
- Total Revenue at Q1 (TR1): $2,500
- New Quantity (Q2): 55 units
- Total Revenue at Q2 (TR2): $2,650
Using the formula:
MR = (TR2 - TR1) / (Q2 - Q1)
MR = ($2,650 - $2,500) / (55 - 50)
MR = $150 / 5
MR = $30 per unit
This means, on average, each of the additional 5 units sold generated $30 in revenue.
