Formula for figuring a multiplier in a range

[Doc_H]

Hi all, I'm new to the forum and I'm thankful for it as it is a great source of knowledge.

Here's my dilemma:
I am in need of a formula that will figure out a multiplier number from a range of numbers. Here's the example I'm working with. This will be used in a worksheet to measure performance and incentive pay for my group and below is a sample of one of the many goals for the group. Incentive will be calculated on a point system. The multiplier is based on the "Actual Result" or performance of the individual. With that said, if the value falls between a range within say, the threshold rate of 1.75% and the target rate of 1.25%, what formula can assist in figuring out the actual multiplier?

Available Points		(Multiplier)	Targets			ACTUAL RESULT		POINTS EARNED
15		50%	Threshold	1.75%		1.36%		=Multiplier X Available Points
		100%	Target	1.25%		Multiplier
		200%	Maximum	0.75%

Any assistance is greatly appreciated!

Thank you!

Thanks for the response, HOTPEPPER. After inputting the formula into my spreadsheet, it is calculating the multiplier as 1500.00%. I'm probably missing something but can't figure out what it is.

Thanks again!

My formula is not returning the multiplier, it is returning the Points Earned, per your example (Multiplier x Available Points)

 

[Doc_H]

Thanks for clearing that up. I entered it into the Points Earned field and it assumed a multiplier of 1x or 100% based on a result of 1.36%.

Is there a way to get a more accurate multiplier or "points earned" result based on the actual result percentage? For instance, if the actual result were 1.70%, which is closer to threshold, the multiplier in that case would be closer to 50% or 7.5 points but if the multiplier were 56% then the points would increase to 8.4. In essence, I'd like to multiplier to be anywhere in the range of 50% and 200% and not necessarily 50%, 100%, and 200%. I hope i'm not convoluting this response too much.

Thanks, shg. This is really good stuff. Do I need to input the code using VBA or can I use the formula directly?

 

[shg]

It's just a formula.

 

[Doc_H]

I tried the formula but didn't have much luck. =PERCENTRANK(ARRAY,X,SIGNIFICANCE) gives the right idea but the formula assumes that 1.75% is 100%, 1.25% is 50%, and 0.75% is 0%. Any thoughts?

Thx

That's the table in A1:B3.
