Ecommerce Forecasting Tool, now with Cohorts

Today I released an update to the Ecommerce Forecasting Tool that adds an expanded approach to the Forecast sheet to forecast retention on a per-cohort basis and adds a new Historicals sheet to analyze past cohort performance. The Historicals sheet allows you to drop in historical retention data for your business and use it to automatically create an average retention curve for forecasting.

As always, you can download the updates through your original email receipt or by logging into Gumroad. The model is free; all donations, ratings and reviews are appreciated.
