Present Perfect Simple vs. Present Perfect Continuous

• We use both of these tenses to connect the past to the present. Present perfect continuous focuses on the ongoing duration of an activity. Present perfect simple focuses on the completed result, amount, or state.
• Aspect
• Present Perfect Continuous (ongoing/duration)
• Present Perfect Simple (result/completed/how many)
• Focus
• How long an action has been happening
• How much or how many times an action has happened
• Form
• has/have + been + -ing verb
• has/have + past participle
• Example
• He has been waiting at the dock for four hours.
• He has called the broker three times today.
• State Verbs
• Not used (State verbs cannot be continuous)
• Used for state verbs (e.g., 'We have known him since 2021')
• Remember
• Use the present perfect continuous to stress the duration of an activity that started in the past and continues now.
• Use the present perfect simple to focus on the completed result or to state how many times something occurred.
• Never use the continuous form with state verbs like know, need, belong, or seem.
• Examples
• Thomas has been driving since 6:00 AM.
• The carrier has submitted four detention invoices this week.
• We have known about this delay for two hours.
• Common mistakes
• He has been knowing the shipper since last year.
• He has known the shipper since last year.
• I have been calling them five times this morning.
• I have called them five times this morning.
