Work out interpretation hours cost instantly with clear inputs, formula shown and shareable results.
Simultaneous interpretation requires two interpreters per language pair working in twenty to thirty minute turns, because sustained concentration cannot be maintained alone. Six hours at 85 an hour for two interpreters is 1020, and the four hour minimum means short sessions cost the same as half-day ones.
Billable hours
billable = max(session hours, minimum hours)
Total cost
cost = billable hours x rate x interpreters
Simultaneous interpretation is cognitively exhausting, and quality degrades sharply after about thirty minutes. Professional standards require a partner for sessions over an hour.
Per hour often yes, and one interpreter may suffice - but it roughly doubles the meeting length, so total cost can be higher.
