I'm still a little confused by your question, but this should work as I understand. Instead of all the IF statements, consider moving into a single CASE statement, defaulting the value to 0. Then add a check if the value isn't 0, to do something.

DECLARE @Level int
DECLARE @Total int
DECLARE @NewPoint int

SET @Level = 61
SET @Total = 100

SELECT 
  @NewPoint = CASE
                WHEN @Level = 61 AND @Total < 482 THEN 10
                WHEN @Level = 62 AND @Total < 487 THEN 15
                WHEN @Level = 63 AND @Total < 492 THEN 20
                WHEN @Level = 64 AND @Total < 497 THEN 25
                WHEN @Level = 65 AND @Total < 502 THEN 30
                ELSE 0
              END

IF @NewPoint <> 0 
BEGIN
  SELECT 'DO SOMETHING'
END
