Download our Excel template below. Fill in your actual monthly volume figures in the Volume column — one row per month. Do not modify the Month or Year columns.
Upload the completed Excel file. The tool requires a minimum of 24 months of data; 36 months (3 full years) is recommended for the best forecast accuracy.
