Survey Response Rate Calculator

Calculate survey response rate and the completed responses a target requires.

About Survey Response Rate Calculator

The response rate is the share of surveys sent that completed responses represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

Formula

Survey Response Rate

Response Rate = Completed responses ÷ Surveys sent × 100

Completed responses
The subset being measured
Surveys sent
The full population it is drawn from

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Survey Response Rate calculated?

Response Rate = Completed responses ÷ Surveys sent × 100 The response rate is the share of surveys sent that completed responses represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small.

Why does Survey Response Rate matter?

Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

What values do I need to enter?

This calculator takes 2 inputs: Completed responses, Surveys sent. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
