I'm trying to write a formula that will adjust price per tier based on adjusted tier level recommendations.

For instance:
Tier List 1:
Tier 1: 0-10M = $1
Tier 2: 10M-15M = $0.85
Tier 3: 15M-20M = $0.65
Tier 4: 20M-MM = $0.5

But let's say I didn't want to stick with those tiers but I wanted the weighted average for each incremental tax bracket:

Tier List 2:
Tier 1: 0-8M
Tier 2: 8M-17M
Tier 3: 17M-25M
Tier4: 25M-MM

Formula to calculate weighted average price for each new range at Tier List 2:

Tier 1= $1 as 8M fits within Tier List 1 (0-10M)
Tier 2= $0.88 ((2M * $1) + (7M * $0.85)) / (17M-8M)
and so on for tier 3 & 4

It needs to be dynamic so the overlaps +/- are captured at their respective tiers. Unfortunately, I don't use macros so I was hoping a formula would be able to do what I want.

What result do you require for say 20,000,000?

A formula can provide the calculation for you.

Well, I'm looking to have my total opportunity (sumproduct) equal between the two tiers.

So, under Tier List 1 20M would equal:
Tier1: 0-10M: $1 +
Tier2: (15M-10M) * $0.85 +
Tier3: (5M remaining) * $0.65 =
$17.5M or average price of $0.875

Tier List 2 should equal the same but different structure:
Tier1: 0-8M: $1 +
Tier2: (17M-8M) * 0.88 +
Tier3: (1M remaining) * $0.56 =
$17.6M or average price of $0.88

And now that I did that calculation, I think I'm realizing there is no way to get my total opportunity value to match exactly because an input volume can vary in the final tier.

Unless, I could automatically run a solver for a volume input for the Tier 3 to be equal to $0.5267 instead of $0.56 so that total calculated value equals $17.5M

But sorry, I don't follow what you're saying subsequently. It doesn't help that some of the numbers you're quoting don't appear to be correct, or to add up?

Sorry for the multiple messages, as I'm still learning how to work everything. My formulas in cell I4 - I7 are incorrect and therefor my list 2 TOV is incorrect as I wanted them to match. I know that if it were calculating correctly, my cell I5, I think would equal (2M * $1 + 5M * $0.85)

Thank you all for your help!

I am not clear on your requirement; a clear example would help.

The post below shows calculations with SumProduct and Sum.
I have clearer examples if this information helps.

Sorry, not sure that my previous mini-sheet made it's way through but perhaps if I described as a tax bracket system. I'm trying to have 2 different brackets (Tier List 1 and Tier List 2) that yield the same value.

So for example if using Tier List 1 for 20M volumes:
10M units x $1
5M units x $0.85
5M units x $0.65
=$17.5M
