Too Many Arguments

I need help with this IF statement for cell L12.

I have it correct until i add in the tiers below for what would be imput into I3


IF(I3<8500.01, IF(L3<0.81, 0.22, IF(L3<0.86, 0.24, IF(L3<0.91, 0.26, IF(L3<0.96, 0.28, IF(L3<1.01, 0.3, IF(L3<1.06, 0.32, IF(L3<1.11, 0.34, IF(L3<1.21, 0.36, 0.38)))))))), IF(I3<1750.01, IF(L3<0.81, 0.2, IF(L3<0.86, 0.22, IF(L3<0.91, 0.24, IF(L3<0.96, 0.26, IF(L3<1.01, 0.28, IF(L3<1.06, 0.3, IF(L3<1.11, 0.32, IF(L3<1.21, 0.34, 0.36))))))))), IF(I3<2850.01, IF(L3<0.81, 0.16, IF(L3<0.86, 0.18, IF(L3<0.91, 0.2, IF(L3<0.96, 0.22, IF(L3<1.01, 0.24, IF(L3<1.06, 0.26, IF(L3<1.11, 0.28, IF(L3<1.21, 0.3, 0.32))))))))), IF(L3<0.81, 0.14, IF(L3<0.86, 0.16, IF(L3<0.91, 0.18, IF(L3<0.96, 0.2, IF(L3<1.01, 0.22, IF(L3<1.06, 0.24, IF(L3<1.11, 0.26, IF(L3<1.21, 0.28, 0.3)))))))))

This is added on sheet 2, but i dont want to keep this formula there, i want to remove it from the workbook.

Tier 1 Tier 2 Tier 3 Tier 4

111% 120% 36% 34% 30% 28%
121% 38% 36% 32% 30%

This kinda sounds like you could use a 2D table, and then use index/match?

But we would need to see a small (clean) sample of what you are working with, and what your expected outcome would look like.
