Juice Calculator: How Much Fruit and Veg per Litre
The juice calculator works two ways. Choose “How much fruit do I need?” to set a target volume and get the fruit, veg, and liquids to buy, or “How much juice will I get?” to enter the produce you already have and see how much juice it makes. Useful when:
- Buying for a batch: set the volume you want and get exact fruit and veg counts before you shop, so nothing goes to waste.
- Using up what you have: enter the fruit and veg in your bowl and see how much juice it makes, and how many glasses that fills.
- Scaling to any size: punch in anything from a single glass to a party jug and the amounts scale automatically.
- Mixing produce, liquids, and tasters: balance a strong beetroot or carrot base with water or coconut milk, and dial in ginger or mint to taste.

How the Juice Calculator Works
Each fruit and vegetable has a juice yield: the percentage of its whole weight that becomes liquid. Cucumber and celery sit at around 90%, meaning you need only about 111 g of whole cucumber to get 100 ml of juice. Apple and pear are around 55%, so you need roughly 182 g for the same 100 ml. Lemon and mango sit at the lower end at around 45%, requiring around 222 g per 100 ml. Leafy greens are lower still: spinach yields around 35% and kale around 30%, so a handful of leaves gives far less juice than its bulk suggests.
The calculator multiplies your target volume by each ingredient's ratio percentage, then divides by the yield to find the whole-fruit weight needed. It then uses the produce converter to turn that weight into whole-item counts, cups, or ounces, adjusted for the size you set. Liquids like water or coconut milk skip the yield step: their percentage maps straight to volume.
How Much Juice Will You Get From What You Have?
Switch to the “How much juice will I get?” tab when you have a pile of fruit and veg and want the yield before you start. Add each item, enter how many whole pieces, grams, or cups you have, and the calculator totals the juice as a single bar, split by ingredient, plus how many glasses it fills. It uses the same yields as the planner, so a 1 kg bag of carrots (50% yield) shows about 500 ml, while the same weight of cucumber (90%) gives closer to 900 ml.
Tips for Blending Ratios
A good starting point for a mixed green juice is around 40% cucumber or celery (high yield, light flavour), 30% apple or pear (sweetness and body), and 30% leafy greens such as spinach or kale. For a tropical blend, combine pineapple, mango, and orange in roughly equal thirds. Adjust the sliders until the total shows 100%, and use the taster controls to add ginger or mint.
Juice Yield Reference
These approximate yields are built into the calculator. The table below also shows how much juice to expect from one medium-sized item of each. They assume a centrifugal or cold-press juicer; a blender and strainer gives slightly lower yields.
| Produce | Juice yield | Juice per medium item |
|---|---|---|
| Apple | 55% | ≈100 ml |
| Beetroot | 50% | ≈41 ml per beetroot |
| Bell Pepper | 65% | ≈77 ml |
| Cantaloupe | 85% | ≈935 ml |
| Carrot | 50% | ≈31 ml |
| Celery | 90% | ≈36 ml per stalk |
| Cucumber | 90% | ≈270 ml |
| Grapefruit | 65% | ≈160 ml |
| Grapes | 65% | ≈3 ml per grape |
| Honeydew Melon | 85% | ≈1,105 ml |
| Kale | 30% | ≈105 ml per bunch |
| Kiwi | 65% | ≈59 ml |
| Lemon | 45% | ≈52 ml |
| Lime | 55% | ≈37 ml |
| Mango | 45% | ≈151 ml |
| Nectarine | 50% | ≈71 ml |
| Orange | 55% | ≈99 ml |
| Peach | 50% | ≈75 ml |
| Pear | 55% | ≈98 ml |
| Pineapple | 55% | ≈825 ml |
| Pomegranate | 55% | ≈154 ml |
| Radish | 55% | ≈8 ml |
| Spinach | 35% | ≈98 ml per bunch |
| Strawberry | 60% | ≈7 ml |
| Sweet Potato | 45% | ≈90 ml |
| Tomato | 65% | ≈80 ml |
| Watermelon | 65% | ≈2,925 ml |
Frequently Asked Questions
- How many oranges do I need to make 1 litre of juice?
- A medium orange weighs about 180 g whole, and oranges yield roughly 55% of their weight as juice. To make 1 litre you need about 1818 g of whole oranges, which works out to roughly 10 medium oranges. Use large oranges and you will need closer to 7. The juice calculator works this out for any volume and size. Open orange converter
- How much ginger should I add to a juice?
- A good starting point is about 17 g of fresh ginger per litre of juice at the default mid setting, which gives a noticeable but not sharp warmth. Slide the strength dial toward 'a little' for around 4.5 g per litre, or toward 'strong' for up to 30 g per litre. The calculator scales the amount automatically with your total juice volume, so you can dial it in without doing the sums. Open ginger converter
- What is juice yield and why does it matter?
- Juice yield is the percentage of a whole fruit or vegetable's weight that becomes liquid when juiced. Cucumber and celery yield around 90%, so you need very little of them. Lemon yields around 45%, so you need around 222 g to get 100 ml, close to twice the weight you would need from cucumber. Knowing the yield stops you from under- or over-buying ingredients before you start.
- How many apples does it take to make a litre of apple juice?
- Apples yield about 55% of their weight as juice. To get 1 litre of apple juice you need approximately 1818 g of whole apples. A medium apple is about 182 g, so that is roughly 10 medium apples. Smaller apples mean more pieces; the calculator adjusts the count when you change the size setting. Open apple converter
- Can I add liquids like coconut milk or water to a juice blend?
- Yes, liquids such as water, coconut milk, almond milk, and lemon juice can be added as main ingredients in the juice calculator. Their percentage maps directly to volume rather than juice yield, so 20% of a 1 litre blend adds 200 ml of that liquid. This lets you dilute a strong beetroot or ginger blend or add a creamy base to a tropical mix.
- How much juice will I get from 6 oranges?
- Switch the calculator to 'How much juice will I get?' and add oranges. Six medium oranges weigh about 1080 g together, and oranges yield roughly 55% of their weight as juice, so you get around 594 ml, close to two and a half 250 ml glasses. Use large oranges and the same six give about 825 ml. Change the size dropdown to match what you bought. Open orange converter
- How much juice will I get from a bag of carrots?
- Carrots yield about 50% of their weight as juice, so a one-kilogram bag makes roughly 500 ml, about two 250 ml glasses. In the 'How much juice will I get?' mode, add carrot, switch the unit to grams or kilograms, and enter the weight you have. Mixing in a high-yield vegetable like cucumber or celery stretches the total without needing more carrots. Open carrot converter
- Can I work out juice from strawberries measured in cups?
- Yes. Berries are easier to measure by the cup than to count, so the 'How much juice will I get?' mode lets you enter strawberries in cups. A metric cup of strawberries is about 166 g, and strawberries yield around 60%, so each cup gives roughly 100 ml of juice. Two cups make about 200 ml, a little under one 250 ml glass.
