How the lemonade calculator works

This planner has four modes. Recipe mode scales a classic lemon to sugar to water ratio to the servings you want. Party serving mode turns a guest count into total lemonade, lemons, ice, and a container suggestion. Concentrate mode tells you how much water to add to a concentrate. Commercial batch mode sizes a large batch and estimates its cost. Pick a sweetness, choose your lemon source, and it lays out exactly what to buy.

Fresh lemon conversion and sugar tips

One medium lemon yields roughly 2 to 3 tablespoons, about 45 ml, of juice, so a cup of juice takes around five to six lemons. Roll them firmly and bring them to room temperature for the most juice. To cut sugar, drop to the light sweet ratio, replace part of the sugar with a touch of honey or a sugar substitute, or add more water and a little extra lemon for brightness. Dissolving sugar in warm water as a simple syrup first avoids grit.

Frequently asked questions

How much lemonade for 50 people? About 6 gallons for a couple of servings each, more in hot weather or for a long event.

How many lemons do I need? Roughly five to six lemons per cup of juice; a gallon of classic lemonade uses about 3 cups of juice, so 15 to 18 lemons.

What is the lemonade ratio? A classic ratio is 1 part lemon juice to 1 part sugar to 4 parts water, adjusted to taste.
