Cream is one of the most calorie-dense dairy products because its calories come almost entirely from milk fat. A heavy cream can pack 340 kcal per 100 g, while lighter options like half-and-half deliver closer to 133 kcal. This calculator lets you quickly see how the cream type and portion size affect your totals — whether you're tracking calories, macros, or keto-friendly fat intake.
Choose your cream type, enter the amount in grams, tablespoons, or cups, and the tool will calculate total calories, calories per 100 g, fat, carbohydrates, protein, and the share of calories coming from fat. Quick presets for common serving sizes make logging even faster.
This is a practical companion for meal prep, coffee drinks, sauces, desserts, and any recipe where cream makes a significant calorie contribution. Use it alongside nutrition labels to keep your daily targets on track.

How to Use This Calculator
Start by selecting the cream type that matches your product. The default is heavy cream, but you can switch to whipping cream, light cream, sour cream, or half-and-half. Enter the amount and choose the matching unit: grams, tablespoons, or cups. Recipe-ready preset buttons fill in 1 tbsp, ¼ cup, ½ cup, or 1 cup and switch the unit to grams automatically. After you click Calculate, the results panel shows total calories, calories per 100 g, fat, carbs, protein, and the share of calories from fat, plus a formula line so you can verify the math against your nutrition label.
Tip: For the most reliable numbers, weigh the cream rather than measuring by volume. A digital kitchen scale removes the guesswork that comes with viscous liquids.
Calorie Reference by Cream Type
The values below are typical per 100 g figures based on standard US nutrition data. Fat content varies by brand and by country, so always check the label on the product you actually use.
| Cream type | Fat | Calories | Fat (g) | Carbs (g) | Protein (g) |
|---|---|---|---|---|---|
| Heavy cream | 36% | 340 | 36 | 2.8 | 2.8 |
| Whipping cream | 30% | 292 | 30 | 3.0 | 2.0 |
| Light cream | 20% | 196 | 20 | 3.0 | 3.0 |
| Sour cream | 20% | 198 | 19.3 | 4.7 | 2.4 |
| Half-and-half | 12% | 133 | 12 | 4.4 | 3.1 |
For brand-level data, consult USDA FoodData Central. Many cartons also list “per 100 ml” on the nutrition facts; for cream this is close to 100 g because the density of cream is near 1 g/ml.
How the Calculation Works
The core formula is simple:
Total calories = (calories per 100 g ÷ 100) × amount in grams
For example, suppose you add 80 g of whipping cream to a sauce. Whipping cream has about 292 kcal per 100 g, so the calculation is 2.92 × 80 = 233.6 kcal. The same portion supplies about 24 g of fat, 2.4 g of carbohydrates, and 1.6 g of protein.
Fat drives almost all of cream's calories. Fat provides 9 kcal per gram, so the calculator estimates calories from fat by multiplying fat grams by 9. In heavy cream roughly 95% of calories come from fat; in half-and-half the share is still about 80%.
Why Fat Content Drives Cream Calories
Cream is essentially milk fat suspended in water. As fat content rises, calorie density rises with it, which is why 100 g of heavy cream has about two and a half times the calories of 100 g of half-and-half. Fat percentage also affects cooking behavior: higher-fat creams whip more easily, resist curdling in acidic dishes, and add richer mouthfeel, while lower-fat options are better for lighter sauces and coffee.
Note: Sour cream is a fermented product rather than a pouring cream, but it appears here because it is often used in similar portions. Its calorie and fat values are close to light cream because both commonly sit around 20% fat.
Tips for Accurate Tracking
- Weigh cream in grams when you want exact numbers; volume measurements are convenient but less precise.
- Use the nutrition label on your specific carton. Organic, grass-fed, and imported creams can vary by a few grams of fat per 100 g.
- If the label gives per 100 ml, remember that 100 ml of cream weighs roughly 99–100 g, so the calorie total is effectively the same for practical purposes.
- Be careful with “light” products: light cream and light sour cream use different formulations, and some contain thickeners that change the carb count.
- When adding cream to coffee or tea, count it as a separate ingredient. If your drink also contains milk, the latte calorie calculator can help you estimate the combined total.
Frequently Asked Questions
Is heavy cream keto-friendly? Yes. With roughly 2.8 g of carbs per 100 g and a high fat content, heavy cream fits easily into low-carb, ketogenic, and carnivore meal plans when portions are kept reasonable. Half-and-half is also low in carbs but supplies less fat and fewer calories.
How many calories are in a tablespoon of heavy cream? One level tablespoon weighs about 15 g and contains roughly 51 kcal and about 5.4 g of fat. Whipping cream is close at around 44 kcal per tablespoon, while half-and-half drops to about 20 kcal per tablespoon.
Can I use this calculator for whipped cream? The calculator assumes liquid cream before whipping. Whipped cream contains the same cream with air incorporated, so calories per 100 g by weight are close to liquid cream; however, a volume scoop of whipped cream has far fewer calories because of air. Weigh it whenever possible.
Why does my label show slightly different numbers? Food labels use approved rounding rules, and fat content can vary slightly between batches. This calculator uses standard per 100 g figures to give a reliable estimate rather than a legally exact value.
