What does the Total at the bottom of the list count?

Short answer: The Total adds up every order matching the current filters, not just the ones on the page shown. Canceled orders are left out, and refunds are deducted.

What goes into it


Every page	The total does not stop at the 25 or 50 rows on screen: it covers the whole result.
The current filters	A search or an active Status filter shrinks the total by as much. Clear them to get the general total back.
No cancelled orders	A Canceled order does not count; its amount shows as a dash in the list anyway.
Refunds deducted	A partially refunded order counts for what was actually kept.

So it is a total collected on the shop.
