More clarity. Less guesswork.
Calorie Cup is an independent Starbucks calorie calculator for people who want to understand their usual order. We focus on a small, traceable US menu, and separate official default nutrition from estimated customizations. The calculator runs on your device without an account.
Our calculation method
Each size has its own official baseline and default recipe. We calculate changes relative to that recipe. Manufacturer ingredient labels inform our comparison model; serving amounts are assumptions. Milk replacements subtract the original milk before adding the replacement. Missing values remain missing. Results are rounded for reading, so totals may not match the sum of rounded parts.
Independent tool. Not affiliated with or endorsed by Starbucks Coffee Company.
How we estimate customizations
Milk volume is estimated from the default recipe, not the cup’s full capacity. Milk swaps use Horizon and Oatly nutrition labels as proxies, not verified Starbucks supplier labels. Syrups use a Torani vanilla proxy: 7.5 ml per full pump (20 kcal); Frappuccino uses a 3.75 ml half-pump model. Espresso adds an estimated 5 kcal and 75 mg caffeine per shot (65 mg for Flat White ristretto). Foam and whip use generic portion models; they do not account for displaced drink volume. Changes to pumps or shots keep the modelled milk amount constant.
Topping model: whip = 30 ml heavy cream + 7.5 ml syrup; cold foam adds 30 ml 2% milk. These are comparison assumptions, not Starbucks recipes. Powders, sauces, drizzle, decaf, and other toppings cannot be edited in this version.
Menu availability varies by café. Unsupported combinations are not offered. Missing nutrition stays unavailable.
