How much caffeine content in an 8-ounce cup of coffee?

The caffeine contents vary according to the type of coffee you are drinking:

Brewed Coffee is also known as regular coffee:

Hot or boiling water is poured over ground coffee beans, usually contained in a filter.

An 8 oz cup of brewed coffee contains between 70–140 mg of caffeine or approximately 95 mg on average 

Espresso:
It is prepared by forcing a small amount of hot water, or steam, through finely-ground coffee beans.

Though espresso has more caffeine per volume than regular coffee, it usually contains less per serving, because of the smaller serving portion of one shot. 

One shot of espresso averaging 30–50 ml (1–1.75 oz) contains about 63 mg of caffeine and about 125 mg of caffeine for a double shot of espresso.

Espresso-Based Drinks:
Other popular coffee drinks made with espresso shots mixed with varying types and amounts of milk, such as lattes, cappuccinos, macchiatos, and Americanos.

Milk does not contain any caffeine, so these drinks have the same amount of caffeine as straight espresso.

About 63 mg of caffeine for a single and 125 mg for a double.

Instant Coffee
The coffee is freeze-dried or spray-dried made from brewed coffee and usually in large dry pieces which dissolve in water.

Instant coffee usually contains less caffeine than regular coffee, averaging 30–90 mg per cup.

Decaffeinated Coffee:
It is not entirely caffeine-free. It does contain some amounts of caffeine, ranging from 0–7 mg per cup, with the average cup containing 3 mg.

Depending on the method of decaffeination and cup size some varieties may contain even higher amounts of caffeine.

An 8-oz brewed cup of coffee averages 95 mg. An espresso or espresso-based drink has 63 mg and about 3 mg of caffeine for decaffeinated coffee.
