How to calculate marginal revenue?


Remember that frustrating time you dropped your product price to attract more customers, only to see profits stagnate? Understanding marginal revenue could have helped you make a different, more profitable decision.

Marginal revenue isn’t just another financial term; it’s a powerful tool for businesses aiming to optimize pricing, manage production, and ultimately, maximize profits. But what exactly is it, and how can you calculate and utilize it for your business? Buckle up, entrepreneurs, because we’re diving deep into the world of marginal revenue!

How to calculate marginal revenue?

  • The Money-Making Magic

Simply put, marginal revenue is the additional revenue you earn by selling one more unit of your product or service. It’s a measure of the impact each additional sale has on your bottom line. Why is this crucial? Because unlike total revenue, which tells you your overall sales, marginal revenue reveals the profit potential of each incremental sale.

  • Unlocking the Formula

Calculating marginal revenue is straightforward. Just grab your trusty calculator and use this formula:

  • Marginal Revenue = Change in Total Revenue / Change in Quantity Sold

Let’s say you initially sell 10 widgets for $10 each, earning $100 in total revenue. If you manage to sell 11 widgets at the same price, your total revenue becomes $110. The change in total revenue is $10 (110 – 100). Now, since you sold one more widget (11 – 10), the change in quantity sold is 1. Divide the change in revenue by the change in quantity, and voila! Your marginal revenue is $10.

  • Beyond the Numbers

That $10 marginal revenue tells you that selling one more widget adds $10 directly to your profits (assuming your variable costs per widget are less than $10). Understanding this metric empowers you to make informed decisions on:

  • Pricing: Set optimal prices that balance maximizing revenue with market demand, based on your marginal revenue analysis.
  • Production: Decide when to increase or decrease production, considering the profit potential of each additional unit.
  • Promotions: Evaluate the effectiveness of discounts and promotions by analyzing their impact on marginal revenue.


While marginal revenue is a powerful tool, it’s not a magic bullet. Here are some key points to keep in mind:

  • Fixed costs: Don’t forget to factor in fixed costs like rent and salaries when evaluating profitability.
  • External factors: Market trends, competitor actions, and economic conditions can influence your marginal revenue.
  • Monitoring matters: Regularly track and analyze your marginal revenue to adjust pricing and production strategies as needed.
  • Empowering Your Business

Ready to unlock the growth potential of your business? Start incorporating marginal revenue analysis into your decision-making process. Here are some actionable tips:

  • Track your sales data: Log total revenue and quantity sold for each product or service period.
  • Calculate your marginal revenue: Use the formula and track it over time to identify trends.
  • Analyze and adapt: Use your findings to adjust pricing, production, and marketing strategies for maximized profitability.

Remember, every sale matters. By harnessing the power of marginal revenue, you can make informed decisions that fuel your business success. So, go forth, calculate, and watch your profits soar!
