Plain ice cubes made from water have zero calories, but many ices are actually frozen flavored drinks, juice pops, milk cubes, or homemade sorbet bases. If you freeze a sweet liquid, the calories do not disappear; they become more concentrated per 100 g when you compare frozen cubes with the original liquid volume. This calculator lets you enter the total weight and total calories of a full batch, then instantly see the real calorie count per 100 g, per gram, and per serving.
Use it for homemade ice pops, fruit-juice ice cubes, frozen coffee, sweet tea cubes, or any frozen dessert you want to track. The optional macro fields also give you sugar, carbohydrate, protein, and fat per 100 g from your batch totals. Pair the result with the serving-size input to plan portions for clean snacking, meal prep, or a refreshing low-calorie treat.

How to Use This Tool
Start by weighing the full batch of frozen ice in grams, or enter the volume in milliliters, fluid ounces, or cups. If you use a volume unit, choose the closest density for the base liquid: plain water and most fruit juices are close to 1.00 g/mL, milk is about 1.03 g/mL, and creamy milkshake bases run closer to 1.05 g/mL. Next enter the total calories for the whole batch and, optionally, the grams of sugar, carbs, protein, and fat for the entire tray. The calculator converts everything to a per-100 g figure, then scales it to any serving size you request.
Tip: To get the most accurate batch calories, add up the calories printed on each ingredient label before freezing. This works for store-bought juice, homemade sweet tea, flavored coffee, or any blend you pour into molds.
Formula Explained
The calculation is simple proportion math. Once the batch weight is converted to grams, the formula is:
Calories per 100 g = (Total batch calories ÷ Total batch weight in g) × 100
Per serving = Calories per 100 g × serving size in g ÷ 100
Macros per 100 g = (Total macro grams ÷ Total batch weight in g) × 100
Freezing a liquid does not create or destroy calories. It only changes the volume and texture, so the calorie count of the original drink is simply carried into the frozen cube or pop.
Sample Results
Imagine you freeze 400 mL of orange juice that contains 180 kcal for the whole batch. Since juice density is near 1 g/mL, the batch is about 400 g. The calculator returns 45 kcal per 100 g, 0.45 kcal per gram, and 90 kcal for a 200 g pop. If you freeze 300 g of whole milk at 61 kcal per 100 g, that batch adds up to 183 kcal, and a small 75 g ice cube holds about 46 kcal.
Reference: Calories in Common Frozen Bases
| Frozen base | Approx. kcal per 100 g | Serving note |
|---|---|---|
| Plain water ice | 0 | No calories |
| Black coffee ice | 0–2 | Great for iced coffee |
| Unsweetened tea | 0–3 | Refreshing and light |
| Coconut water | 19 | Light tropical pop |
| Lemonade | 35–50 | Sweet flavor, low calories |
| Orange juice | 45 | Natural fruit sugars |
| Whole milk | 61 | Creamier cube |
| Mango juice | 55–65 | Higher natural sugar |
| Sweetened sorbet | 90–120 | Denser dessert |
| Ice cream base | 150–210 | Treat, small portions |

Tips & Best Practices
- If your batch is mostly air or whipped, weigh it instead of measuring by volume for the most reliable per-100 g numbers.
- For very sweet drinks, remember that the sugar calories stay in the ice and become more noticeable per 100 g once you compare frozen and liquid servings.
- Enter macros only when you actually know the batch totals; leaving a macro field blank keeps that result as a dash instead of a guessed zero.
- Use the serving-size field to plan snack portions for kids or for a low-calorie dessert plate.
Frequently Asked Questions
Does freezing water change its calories? No. Plain water ice contains zero calories before and after freezing. The only way ice has calories is if the liquid you froze contained sugar, fat, protein, or other calorie-bearing ingredients.
Why does my juice pop seem higher in calories than the original juice? The calories per 100 g do not change when you freeze juice; only the serving math can appear different because people often eat a whole pop or cube, whereas they might pour a smaller glass of liquid.
Can I use this for ice cubes made from leftover smoothie? Yes, that is exactly what this calculator is for. Just weigh a small sample of the cube batch if you did not weigh the full tray before freezing.
