What is Marginal Revenue?
Marginal Revenue (MR) is the additional income generated from selling one more unit of a product or service. It helps businesses determine optimal production levels and pricing strategies. By calculating marginal revenue, companies can make informed decisions about whether to increase or decrease output to maximize profits. Understanding MR is crucial for profit optimization, cost analysis, and efficient resource allocation in various business scenarios.

Marginal Revenue Formula
The formula to calculate marginal revenue is:
MR = ΔTR / ΔQ
Where:
MR = Marginal Revenue
ΔTR = Change in Total Revenue
ΔQ = Change in Quantity Sold
How to Use This Calculator
Enter the total revenue change (difference between new and old revenue) and quantity change (difference in units sold) in the input fields. Click "Calculate" to get instant results. Use "Clear" to reset inputs. The calculator automatically computes marginal revenue using the MR formula. Ensure both values are positive numbers for accurate calculations. This tool helps business owners, students, and economists quickly determine revenue per additional unit sold without manual calculations.
Calculation Process
1. Determine the change in total revenue (ΔTR) by subtracting previous revenue from new revenue
2. Calculate the change in quantity sold (ΔQ)
3. Divide ΔTR by ΔQ to get marginal revenue
4. Positive MR indicates profitable production expansion
5. Negative MR suggests reducing production quantity
6. Compare MR with marginal cost for optimal decisions
Frequently Asked Questions
What is marginal revenue used for?
Marginal revenue helps businesses determine the financial impact of producing additional units. It's essential for optimizing production levels, setting prices, and maximizing profits. By comparing MR with marginal cost, companies can make informed decisions about expanding or reducing output.
Can marginal revenue be negative?
Yes, marginal revenue can become negative when the cost of producing additional units exceeds the revenue generated from selling them. This typically occurs when market saturation forces price reductions to sell more units, leading to decreased overall revenue.
How does marginal revenue differ from average revenue?
While average revenue shows income per unit sold (total revenue divided by quantity), marginal revenue specifically measures the income from selling one additional unit. MR is more dynamic and changes with production levels, while average revenue tends to decrease as quantity increases.
What is the relationship between MR and price elasticity?
Marginal revenue directly relates to price elasticity of demand. In elastic markets, MR remains positive as price changes significantly affect quantity demanded. In inelastic markets, MR decreases faster and can turn negative more quickly with increased production.
Why is MR important in perfect competition?
In perfectly competitive markets, marginal revenue equals the market price because firms are price takers. This relationship helps determine the profit-maximizing quantity where MR equals marginal cost (MC), ensuring efficient market equilibrium.
How does MR affect pricing decisions?
Businesses use MR to set optimal prices by comparing it with marginal cost. When MR > MC, increasing production boosts profits. When MR < MC, reducing production maximizes profits. The ideal production level occurs where MR = MC.
What's the difference between MR and marginal profit?
Marginal revenue focuses solely on additional income from sales, while marginal profit considers both revenue and cost changes. Marginal profit = MR - Marginal Cost (MC). This distinction helps in comprehensive profit analysis and decision-making.
How do you calculate MR from a demand curve?
For linear demand curves, MR has twice the slope of the demand curve. If demand is P = a - bQ, then MR = a - 2bQ. This relationship helps predict how revenue changes with quantity in different market structures.
What factors influence marginal revenue?
Key factors include market structure, price elasticity, production costs, competition level, and consumer demand. Changes in any of these elements can significantly impact MR calculations and subsequent business decisions.
How often should businesses calculate MR?
Businesses should calculate MR regularly, especially when considering production changes, entering new markets, or adjusting prices. Frequent calculation helps maintain optimal pricing strategies and adapt to market fluctuations effectively.
