The price of a cup of lemonade varies, but it generally would not be smart to sell lemonade at a stand for more than $5. Even on a sweltering hot day, customers are unlikely to pay more than $5 for a regular sized cup of lemonade. $2-4 is the best price to sell a regular cup of lemonade for, but you could possibly sell a larger cup of lemonade for $6-8. There are a variety of other factors that should be considered when opening a lemonade stand and how much you can charge once you are set up.
One factor is location. A lemonade stand can be on a busy commercial street or a quiet neighborhood street. For either location, it is important that there is foot traffic – people driving vehicles are a lot less likely to stop for lemonade, especially if they have to park and get out of the car. Pedestrians on a commercial street might want to buy lemonade because they need something in a hurry, but customers in a residential area might be willing to pay more because you are close to their house. While there are more potential customers in a commercial area, you will be competing with retail businesses that might charge less or ask you to go somewhere else. Therefore, a reasonably busy residential area is the best place for a lemonade stand. You can charge more for a cup of lemonade in this type of location.
You can also charge a higher price, like $5, if your lemonade is fresh squeezed and home-made. Most people feel like home-made lemonade that is made from lemons and other fresh ingredients that day tastes a lot better than store-bought lemonade, which they can easily buy themselves. Customers will also respect the work that you put into making the lemonade yourself and be more willing to pay for it.
