MYSQL Calculate ranking of row that is not yet inserted

I've got a table similar to this data:

|     id    | username | value |
|-----------|----------|-------|
| 1         | bob      | 46    |
| 483       | alice    | 90    |
| 176       | sue      | 3001  |
| 82        | harry    | 0     |
| 10493     | bill     | 327   |

I have this query that returns me the ranking of a user based on their id

SELECT 
    username, 
    value, 
    rank from 
    (
        SELECT 
        tp.username, 
        tp.value,
        tp.id, 
        @curRank := @curRank + 1 AS rank
        FROM table tp, 
        (SELECT @curRank := 0) r
        ORDER BY tp.value DESC
    )
as temp
WHERE id = 483;

So for the above query, I would get a ranking returned of 4 for the id 483.

Let's say I want to insert the following row into the table:

|   id   | username | value |
|---------------------------|
|    2   |  sally   | 2000  |

Is there any way to know what rank this row will have after it is inserted, without actually inserting it?

I.e. sally would have a rank of 2 from the above query if inserted.

The reason I am curious if this is possible is that I'm attempting to insert the row into the database and only have this one transaction, rather than having to insert the row, then re-run the rank query.

Thanks!
