mate I do but in different formats
Where you deal with costings, budgeting etc... I deal with other matters
=IF(E101>180000,(+E101-180000)*0.45+54547,IF(E101>80000,(+E101-80000)*0.37+17547,IF(E101>37000,(+E101-37000)*0.325+3572,IF(E101>6000,(+E101-18200)*0.19,0))))
=IF(E101>17795,+E101*0.015,0)
=-IF(E101>67750,0,IF(E101>30000,(E101-30000)*0.04-1500,-1500))
and my formulas make more sense
