How to sum values by month from Date column?

Hi,

What I want is to create a sum of sales by month. Those dates dates need to read and updated from a Date column.

Here is my table

For example, I want to see what is the TotalPrice for August, September etc.

How to achieve that?!

Make a new column with a formula that formats the date as a string containing just the year and month. Then create a summary table grouped by that new column.

By the way, there is a recipe for getting year + month from a date here: Recipe for getting Months and Quarters from dates
