Pick a drink, size, milk and how many pumps of syrup, then see the calories and sugar in your cup. Based on Starbucks' published values, which may vary by store and customization.

A black brewed coffee is about five calories. Everything above that comes from two places: the milk and the syrup. Once you understand those two levers, you can guess the calories in almost any Starbucks order, and the calculator above will confirm it. Size matters because a bigger cup holds more milk and, by default, more pumps of syrup.
Milk is the quiet driver. The same grande latte swings from about 130 calories with nonfat milk to 220 with whole milk, and oat milk lands near the top because it carries its own sugars. Almond milk is the lightest of the alternatives. If you want a smaller number without giving up flavor, switching milk is usually a bigger win than dropping a single pump of syrup.
Whipped cream adds roughly 70 to 110 calories depending on size. Drinks built on white chocolate or caramel sauce, like the white mocha or caramel macchiato, start higher because the sauce itself is sweet and rich. Adjust the inputs to match exactly how you order and the totals follow.
Build a Chipotle bowl or add up a McDonald's meal the same way.
A grande caffe latte with 2% milk is about 190 calories. Switch to nonfat milk and it drops to around 130, or to whole milk and it climbs to about 220. Flavored syrups add roughly 20 calories per pump on top of that.
Nonfat milk and unsweetened almond milk are the lowest. Oat milk is creamier but higher in calories and sugar, and whole milk is the richest of the dairy options. Swapping milk is often the easiest way to cut a drink's calories.
Most of the sugar comes from the milk and the flavored syrups. Each pump of classic syrup adds about 5 grams of sugar, and a grande typically uses four pumps, so a sweetened drink can carry 30 to 50 grams before whipped cream.
They are estimates based on Starbucks' published nutrition values. Custom orders, extra pumps and whipped cream all change the total, so adjust the inputs above to match how you actually order.
