Marginal Revenue Formula Explained

The calculator uses a simple but powerful economic formula:

Step 1: Total Revenue Calculation

Total Revenue = Price × Quantity

Old Revenue (R1) = Price × Old Quantity
New Revenue (R2) = Price × New Quantity

Step 2: Marginal Revenue Formula

$MR = \frac{R_2 – R_1}{Q_2 – Q_1}$ MR=Q2−Q1R2−R1

Where:

MR = Marginal Revenue
R2 = New Total Revenue
R1 = Old Total Revenue
Q2 = New Quantity Sold
Q1 = Old Quantity Sold

What This Formula Means

This formula calculates how much revenue changes per additional unit sold. It helps determine whether increasing production is profitable or not.

Positive MR → Increasing sales is profitable
Zero MR → No change in revenue
Negative MR → Increasing sales reduces profitability

Example of Marginal Revenue Calculation

Let’s understand with a real-life example.

Scenario:

A company sells a product at $20 per unit

Old Quantity Sold = 100 units
New Quantity Sold = 150 units

Step 1: Calculate Old Revenue

Old Revenue = 20 × 100 = $2000

Step 2: Calculate New Revenue

New Revenue = 20 × 150 = $3000

Step 3: Apply Marginal Revenue Formula

MR = (3000 − 2000) / (150 − 100)
MR = 1000 / 50
MR = $20

Final Result:

👉 Marginal Revenue = $20 per unit

This means each additional unit sold generates $20 in revenue.
