Hi

I'm trying a matrix 2 way lookup where the the columns are for prices based on volume thresholds

I've ben trying to find 1 formula that will work with one set of threshold numbers (D6:H6 in the example below), but I can't seem to geteither Index & Match or Xlookup to do it with one of the match types that works for numbers above or below the smallest or largest volume number

150.029<--Xlookup mode 1 ("exact match or next smaller") - Correct
16Price of 78 of Test 2 is:#N/A<--Index & Match type 1 ("less than") - Not found because there isn't a value in D2:DH smaller than 78
170.04<--Xlookup mode 1 ("exact match or next smaller") : Correct
18Price of 153,000 of Test 2 is:0.01<--Index & Match type 1 ("less than") - Correct

D19D19=XLOOKUP(153000,D6:H6,XLOOKUP(D12,Table4[Test],Table4[[Price 1]:[Price 5]]),,1)


What formula would work for all permutations?

Select a hidden cell
Somehide hide payroll data in column G? Press F5. Type G1. Enter. Look in formula bar while you arrow down through G.
You're Xlookup is looking for an "exact match, or the next larger" not next smaller. Which should it be?

Ah, my mistake thanks. If I use mode -1 it works for volume 231 or 153k examples but not for 78

Actually I don't mind which way round it it is, but I trying to find one formula that will work any number (volume) that is higher, lower or between those values in D6:H6 - i.e >1 but I don't want to have a artificial price column for a volume of 1.


Does that make sense?

In that case if you change the value in H6 to 2,000,000 or any number greater than an expected order, you can then use your xlookup formula

Well...it did occur to me that I could create a spare column, at either end (either for a volume of 1, or a number higher than the largest possible order volume), but that seems a bit redundant. I was hoping that formula could manage with the existing thresholds: up to "n1", "up to n2" ,... "n5 and above"

It's possible to do that, but why jumps through hoops & make your formula more complex, when you can just set the upper limit far higher than any expected value?

I tried adding a column at either end, but still can't find a single formula that returns the expected result:

Then what should the formula if more than 100k units are ordered?
