Assuming years of service is in A1, use this in B1
=IF(A1<1,0,IF(A1<2,7,IF(A1<11,7+(A1-1)*4,IF(A1<16,43+(A1-10)*3,IF(A1<25,59+(A1-16)*2,79)))))




for year 1 you receive 7 weeks pay

Between Year 2 an 10 you receive 4 weeks pay

Between year 11 and 16 year 3 weeks pay

from yr 17 to 25 2 weeks pay, capped at 25 years service.
