When do we use each?

Both tenses are used to express that an action began in the past and is still going on or has just finished. In many cases, both forms are correct, but there is often a difference in meaning: 

• We use the Present Perfect Simple mainly to express that an action is completed or to emphasise the result. 
• We use the Present Perfect Progressive to emphasise the duration or continuous course of an action.

Result or duration?

Do you want to express what has happened so far or how long an action has been going on yet?

Present Perfect Simple	Present Perfect Progressive
Result (what / how much / how often) I have written 5 letters. / I have been to London twice.	Duration (how long) I have been writing for an hour.

Emphasis on completion or duration?

Do you want to emphasise the completion of an action or its continuous course (how has somebody spent his time)?

Present Perfect Simple	Present Perfect Progressive
Emphasis on completion I have done my homework. (Meaning: My homework is completed now.)	Emphasis on duration I have been doing my homework. (Meaning: That's how I have spent my time. It does not matter whether the homework is completed now.)
