SQL-Server-2008R2

I have a member database.
field: familyname, firstname, middlename, paymentDate, validity(months).

SQL

DECLARE @Currendate as date
DECLARE @ACTIVEDATE AS DATE
DECLARE @INACTIVEDATE AS DATE
SET @Currendate= GETDATE()
SET @INACTIVEDATE = DATEADD(MONTH, -24, @Currendate)
SET @ACTIVEDATE = DATEADD(DAY, +1, @INACTIVEDATE)

for active

SQL

SELECT COUNT (*) AS TOTAL
from Member
WHERE DATEADD(MONTH, +validity ,paymentDate) >= @ACTIVEDATE

for inactive

SQL

SELECT COUNT (*) AS TOTAL
from Member
WHERE DATEADD(MONTH, +validity,paymentDate) <= @INACTIVEDATE

i want to add this condition:
if validity >= 24 then validity =24
if validity <= 12 then validity = 12
if validity between 12 and 24 then validity = validity(ex: validity=18)

SQL

--active
SELECT COUNT (*) AS TOTAL
FROM Member
WHERE DATDIFF(MONTH, GETDATE(), paymentDate) <= 12 
--inactive
SELECT COUNT (*) AS TOTAL
FROM Member
WHERE DATDIFF(MONTH, GETDATE(), paymentDate) >= 24
