Peet’s Coffee Caffeine Calculator Peet’s is unusually candid about not knowing its own exact numbers. Its official FAQ states caffeine “falls within a range” for nearly everything it serves — and that range is often wide enough that the smallest and largest ends aren’t close. This calculator uses Peet’s own official figures where they exist, … Read more

Black Rock Coffee Bar Caffeine Calculator: Complete Menu Every figure below is transcribed directly from Black Rock Coffee Bar’s own official nutrition guide, which lists an exact caffeine value for essentially every drink.

BIGGBY Coffee Caffeine Calculator: Complete Menu Every figure here comes directly from BIGGBY’s own official nutrition guide, which — unusually for a coffee chain — lists an exact caffeine value for essentially every drink on the menu. That completeness reveals something most charts miss: BIGGBY’s sizes don’t all scale the same way, and one everyday … Read more

Costa Coffee Caffeine Calculator Every figure here comes directly from Costa’s own official UK caffeine guide, not a compiled estimate. Costa is unusually transparent — it publishes exact milligrams per shot count — which also means it’s the rare chain where you can see an actual quirk in the published numbers rather than a marketing … Read more

Energy Drink Caffeine Database Twenty-four brands, ranked and cross-checked against official can data.

Dose is what really drives the number, not how it tastes or how long the pull runs. Pick a shot type and a bean, and … Read more

K-Cup Caffeine Calculator A K-Cup holds a fixed amount of coffee, and a fixed amount of caffeine comes with it. Choosing a bigger cup size on your Keurig doesn’t add caffeine — it just spreads the same dose through more water. Pick a brand and a brew size below to see both numbers at once: … Read more

Scooter’s Coffee Caffeine Calculator Scooter’s is unusual among coffee chains: its own FAQ officially discloses exactly how many espresso shots go into each size, but never converts that into milligrams. This calculator uses Scooter’s real shot counts and a well-tested per-shot caffeine range to give you an honest estimate — clearly labeled as one, not … Read more

Pre-Workout Caffeine Calculator Pre-workout caffeine spans a much wider range than coffee — from 150 mg in an entry-level scoop to 400 mg in the most aggressive formulas, which is the FDA’s entire daily reference point in a single serving. Pick your product and scoop size, add whatever else you’ve had today, and see exactly … Read more
