Effort Estimator

How to use it?

  1. Have the wireframes or rough sketches ready for reference. Let’s call each wireframe or rough sketch a SCREEN.
  2. For each screen, input details in the form below based on the elements on your screen.
  3. Record the “Effort in Hours” & “Effort Coefficient” values.
  4. If you are confused about a big feature or a product, break it down into individual use stories or use cases before using the Effort Estimator.


Effort Coefficient is just a number and a function of story points and complexity. Story points are calculated for each functional unit in your feature. Total time is calculated in hours per developer based on their experience.
