Consumer Surplus Calculator


Consumer surplus can be explained as the situation where consumer expects a product to be at certain price point but the product is priced lower than he/she expected. For example, James approaches his nearby car dealer to purchase his new car. He plans to finish the purchase within $25,000. But due to new year's eve and promotional offer, the car dealer sells the consumer's new car at an offer price of $22,000. Hence, James have earned a consumer surplus of $3,000.
