About
Making a good smoothie is easy. Making the same good smoothie again — at the right size, with the macros you wanted, at a price you can predict — is where the guessing starts.
That’s the gap this site fills. Free calculators for the math that comes up over and over when you blend: ratios, scaling, nutrition, sugar, and cost. No account required. Nothing you type is stored on a server. Just a number and an explanation of where it came from.
Who runs it
Smoothie Calculator is built and run by its owners — a small operation, not a content farm. If something here is wrong, we’re the ones who fix it, and you can reach us directly.
The tools
- Ratio Calculator — liquid, frozen fruit, base and thickener for the texture you actually want
- Calorie & Nutrition Calculator — calories and macros for any blend, at any number of servings
- Substitution Calculator — swaps ranked by how well they hold the texture
- Sugar Calculator — how much of the sugar is fruit and how much you added
- Cost Calculator — what a glass actually costs to make
- Protein Powder Calculator — scoops against your bodyweight and your goal
- Smoothie Bowl Calorie Calculator — the bowl plus everything you put on top
- Freezer Pack Calculator — batching a week of packs from one shop
- Blender Capacity Calculator — whether the jar you own can hold the batch you planned
New tools get added when enough people ask for the same calculation. If you keep doing something by hand, let us know.
Where the numbers come from
Every ingredient carries nutrition per 100 g — standard published reference values, of the kind used for nutrition labeling — plus the weight of one everyday measure, so any serving size can be worked out rather than looked up. Every calculator and every recipe here uses those same values.
Two things worth knowing. The figures are estimates: brands vary, fruit varies, and how full you pack a cup of frozen fruit varies more than either. And where a chain publishes its own nutrition data, we quote it as theirs, with a link and the date we read it, rather than folding it in with ours.
Every calculation runs in your browser. Nothing you enter goes anywhere.
Who it’s for
Anyone who makes smoothies with intent — for training, health, budget, or just consistency — and would rather not redo the arithmetic every time. Beginners welcome. People who already track everything also welcome.
