McDonald's brewed coffee vs Monster: which has more caffeine?

Monster has more caffeine than McDonald's brewed coffee: 160mg vs 145mg in the same 16 oz can. That is a 15mg gap, and since the cans match, the per-serving number is the whole story.

These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.

McDonald's brewed coffee vs Monster: the numbers

McDonald's brewed coffee Monster
Caffeine per serving 145mg per 16 oz medium 160mg per 16 oz can
Caffeine per fl oz 9.1mg 10.0mg
Servings to reach 400mg (FDA context) 2.8 2.5

Sources: McDonald's brewed coffee's figure is verified in our McDonald's brewed coffee caffeine guide against Caffeine Informer (source); Monster's figure is verified in our Monster guide against Caffeine Informer (source).

Which one should you pick?

Pick McDonald's brewed coffee when you want the lighter dose or a slower ramp, and Monster when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
