Response Rate Estimator

How many questions should your review contain to optimize response rate?

We're often asked, "what is the right number of items for a 360-degree feedback survey to contain?" While in general, we believe shorter is almost always better, you can use the estimator below to calculate the amount of time and expected completion rate of your review based on the number of items you expect it to contain.

You can use this calculator to adjust the number of items in your review for a desired completion rate and amount of time you want raters spending on each response.
