The simple formula
We describe a general formula for predicting the time it takes Workers to complete survey studies on MTurk. The average Worker takes 10.3 seconds to answer a single question. This means that a study with 60 questions should take approximately 10 minutes. At $6 per hour the appropriate pay rate for a 60 question survey would be $1.

What is the completion rate and dropout rate?
Dropout rate is defined as the percentage of participants who start taking a study but do not complete it. Dropout rate is sometimes referred to as attrition rate, and is the opposite of completion rate (dropout rate = 100 – completion rate). On MTurk, completion rate is defined as the number of Workers who submit a HIT divided by the number of Workers who accept the HIT. Note that, for the definition of completion rate used here, Rejected Workers are counted as completes.
