Getting Total Row Count For Complex Query Using CTE

I have a query that uses a CTE which looks similar to this

WITH cte_Products AS
(SELECT SELECT
ROW_NUMBER() OVER (ORDER BY ProductName ASC) AS RowNum,
RANK() OVER (ORDER BY id DESC) AS rank,
FROM Products
WHERE SomeColumn = @SomeVariable)
SELECT rownum,
columns,
(SELECT COUNT(*) FROM cte_Product) AS TotalRowCount
FROM cte_Product AS products
WHERE Rank <= @LastXItems
AND RowNum BETWEEN (@StartRowIndex + 1) and (@StartRowIndex + @MaximumRows)
ORDER BY RowNum

The (SELECT COUNT(*) FROM cte_Product) AS TotalRowCount is in there because I need the total row count that is queried by the CTE. But I feel like this is an inefficient way of doing this. I would just split out the query for the total row count, but then I have to do another sub query to get the rank again since rank is calculated using the Rank method. Does anyone have any ideas of how best to do this?
