Help with IF Formula - New(ish) to Excel

[AllisonCorey]

See formula below, and what I am trying to accomplish:
=IF((D53>=1<=5),D53*0.5,IF((D53>=6<=44),D53*0.42,IF((D53>=45<=66),D53*0.4,IF((D53>=67<=132),D53*0.36,IF((D53>=133<=400),D53*0.3, IF((D53>400), Quote))))))

I am trying to create a formula to help calculate charges... essentially, what I need the formula to do is the following:

If the weight is between:
1-5 lbs, charge $0.50 per lb
6-44 lbs, charge $0.42 per lb
45-66 lbs, charge $0.40 per lb
67-132 lbs, charge $0.36 per lb
133-400 lbs, charge $0.30 per lb
Anything over 400 lbs, Quote.

D53 is the total weight of the order. I don't know what I am doing wrong, as it just keeps calculating as "False"

Any help would be greatly appreciated. Very new to Excel formulas!

I think it's: =IF(D53>400,"Quote",D53*LOOKUP(D53,{1;6;45;67;133},{0.5;0.42;0.4;0.36;0.3}))

If D53 is more than 400, return "Quote", otherwise look up the threshold value in {1;6;45;67;133} and multiply D53 by the equivalent multiplier from {0.5;0.42;0.4;0.36;0.3}.

That worked! Thank you so much for your help.

I'm pleased! And the formula should be easy enough to modify if you change your charging rates at any time in the future.

There are so many functions in Excel, sometimes it's difficult to find the exact right one.
