Mean calculation and compare in sql server 2019

Question

SQL SERVER 2019.

From the below data set how can i calculate :-

The Mean value of (MFR_price-DISTRIBUTOR_cost) than compare with each MFR_price-DISTRIBUTOR_cost and
if Mean value) > each MFR_price-DISTRIBUTOR_cost than 'Performing Good'
if Mean value < each MFR_price-DISTRIBUTOR_cost than 'Occur Loss'
else 'No Gain No Loss'
based on month of Created_date, basically i am trying to analyze whether profit is good or bad for specific month.

Profit = (MFR_price-DISTRIBUTOR_cost)

Data:

DECLARE @LOCAL_TABLEVARIABLE TABLE  
(  
TRACKID VARCHAR (50),  
distance INT,  
ChannelSource VARCHAR (50),  
created_date VARCHAR (50),  
delivered_date VARCHAR (50),  
actual_arrival VARCHAR (50),  
requested_arrival VARCHAR (50),  
MFR_price FLOAT,  
DISTRIBUTOR_cost FLOAT,  
A1_Country  VARCHAR (50),  
A2_Country VARCHAR (50)  
)  
  
INSERT @LOCAL_TABLEVARIABLE

Hi @Uma
Please check this query:

;WITH CTE AS  
(  
 SELECT *,MFR_price-DISTRIBUTOR_cost AS PROFIT_OR_LOSS  
         ,ROUND(AVG(MFR_price-DISTRIBUTOR_cost)OVER(PARTITION BY 1),2) AS MEAN_VALUE  
 FROM @LOCAL_TABLEVARIABLE  
)  
SELECT *,PROFIT_OR_LOSS-MEAN_VALUE AS [PROFIT_OR_LOSS-MEAN_VALUE]  
        ,CASE WHEN PROFIT_OR_LOSS > MEAN_VALUE THEN 'Performing Good'  
		      WHEN PROFIT_OR_LOSS < MEAN_VALUE THEN 'Occur Loss'  
			  ELSE 'No Gain No Loss' END AS REMARKS  
FROM CTE
