Keto drink calculator

Estimate net carbs for coffee, tea, soda, milk drinks, juice, alcohol, and custom keto beverages with clear status labels and practical limits.

When to use

In short: one mode calculates a ready drink from the database, the other helps you build your own recipe by ingredients.

•If you want to check whether a ready drink still fits your carb budget.
•If you are comparing coffee shop drinks, zero-sugar sodas, juices, or alcohol.
•If you want to build your own drink from milk, cream, syrup, sweetener, and add-ins.
•If you need a quick estimate of how much of a drink fits inside your daily carb limit.

How the calculator works

A quick overview of how the result is formed and how to apply it in practice.

Ready Drink mode uses the formula: value = per 100 ml x (volume / 100).

Net carbs are calculated as total carbs minus fiber and sugar alcohols.

Builder mode scales every ingredient to the entered amount, then sums calories and macros across the whole recipe.

The status is simple by design: up to 2 g net carbs is keto, 2-5 g is moderate, and above 5 g is not keto for that serving or recipe.

Practical tips

Small practical steps to help you apply the result day to day.

Unsweetened coffee, tea, water, and many spirits are usually the safest low-carb options.

Milk, syrups, juice, and coffee shop add-ons often raise carbs much faster than the base drink itself.

For custom drinks, keep sweeteners and syrups small, then recheck the total before saving the recipe elsewhere.

If a drink sits close to your limit, use the quick volume buttons to compare 100, 250, 330, and 500 ml portions.

Treat database values as practical estimates, because brands and recipes can vary.

FAQ

Short answers to common questions about calculations and interpretation.

Why can a latte stop being keto so quickly?

Most of the carbs come from milk, not coffee. A larger latte can add several grams of net carbs even without sugar syrup.

Do sugar alcohols always make a drink keto friendly?

Not always. Some drinks still contain milk sugar, juice, or regular syrup, so the total net carbs can remain moderate or high.

Why does Builder mode show recipe servings and volume?

A custom drink can include both grams and milliliters. The calculator sums the whole recipe and estimates drinkable liquid volume from the liquid ingredients.

Can I rely on this for every brand?

Use it as a strong estimate, then compare it with the nutrition label when the exact product matters.

Drink values are general estimates for educational use. Recipes, serving sizes, and brand formulations vary, so always check the label when accuracy matters.
