Statistical Analysis on Scope Pricing :
The other day while looking at scope prices I wondered what parts of the scopes in today's prices attribute to the scopes costs? I took my data from SWFA and Midway, I only included scopes that are out and that are FFP. I took data from 20 different scopes and came out with these variables: Zerostop (true mechanical zerostop), 30mm, 34mm, 35mm, Power ratios 1-3,1-4,1-5,1-6,1-6.5, Illumination, turrets with 10mils or more per rotation. Now my model is no way close to being truly accurate and only covers optics with FFP, mill turrets and from these manufactures: Premier, IOR, Nightforce, S&B, and Zeiss (USO and Leupold had to be thrown out).
Here is the mathematical model that I came up with that determines pricing:
Price = $746 + $433zerostop + $1186 (34mm) + $489 (1-4 power ratio)
+ $785 Turrets 10 mils or larger per turn

Note if a scope has one of the features 1 is yes and 0 is no. For example Premier 5-25 X 50 scope pricing would look like such: $3150=$746 + $433(1) + $1186 (1) + $489(0)
+ $785(1)
Or the new 3-15X50 weaver pricing would be:
$746= $746 + $433(0) + $1186(0)+ $489(0)
+ $785(0)

As you see the Premier pricing is somewhat close $3150 vs listed at $3199
and the weaver is $746 vs listed at $749

What I found was interesting was that just having a 34mm tube you can expect your scope to cost $1186 extra vs one that doesn't. Also turrets with 10 mil or greater will set you back an additional $785. I am going to make a larger data set that incorporates all tactical scopes which I should be done with at the end of the month. I am also going to add some more variables such as location of manufacture, max magnification, and some others. If you guys can think of other variables please tell me. I am still only going to look at FFP with Mil turrets.


For those who care here is the formula more in depth with R-sq values. Also set my Alpha level at .05


Predictor Coef SE Coef T P
Constant 746.0 206.0 3.62 0.011
zerostop 433.1 171.4 2.53 0.045
34mm 1186.4 219.8 5.40 0.002
1-4 489.5 171.4 2.86 0.029
Turrets 10 mils& or greater 785.3 245.0 3.20 0.018


S = 265.503 R-Sq = 95.5% R-Sq(adj) = 92.5%

Note: All other variables not listed proved to be insignificant in determining price.

Thanks for posting this! It is interesting to see the correlation between the cost vs model features broken down like this.
 
Re: Statistical Analysis on Scope Pricing

How do you apply this to a USO were the option to have a 34mm tube is $120US optional extra ?

I wish SB and Hendsoldt used USO's method of priceing a 34mm tube

Re: Statistical Analysis on Scope Pricing

That R-Sq is out of control, wow! Was it that high across the board? The high intercept is interesting as well--wonder if there is a way to get wholesale prices vs MSRP's and build it as a profit variable. That may reduce the intercept and allow the variables to explain more. Very interesting nonetheless! Thanks.

Off the top of my head, I would say that the 34mm variable might better be a "top-tier-manufacturer" variable since it is only really the top-tier-manufacturers that use 34mm tubes (thus the 34mm tube basically identifies scopes as made by top tier manufacturers).

If Bushnell suddenly started selling their 3-12x50 FFP illuminated scope with a 34mm tube instead of a 30mm it might be slightly more expensive, and if S&B started selling their 3-12x50 PMII scope with a 30mm tube instead of a 34mm tube, it might be slightly less expensive, but the change wouldn't be $1186 on either side.

The $1186 represents going from a lower end manufacturer using a 30mm tube to a higher end manufacturer using a 34mm tube rather than from any cost inherent in changing the tube size. I.e., S&B and Premier scopes are just more expensive than the other manufacturers you list. Not trying to say anything bad about Zeiss, they make fantastic optics, but they're not really focused on tactical optics, at least not to consumers in the US (or did you mean Hensoldt when you said Zeiss?).

Also were Leupold and USO thrown out because they messed up the fit of the model or for some other reason?
 
Re: Statistical Analysis on Scope Pricing

Yeah this is what happens when you can't sleep at night. The data is going to be revised in that it is only going to come from midwayusa. I will also add objective and ocular size, overall length, weight, and manufacture origin. I will then post the data on a webpage for you guys to look over to make sure I didn't screw anything up,(as some of these scopes I am not familiar with). I will try to add as many optics as possible and may narrow my data to max magnification of 20 power and lower. USO optics are hard to input data for as they can are a custom outfit and this throws the data off completely. Leupold's new line of optics also doesn't fit any "normal" pricing. So I may just disregard Leupold's entire new line and only include the older optics. I will not include any Chinese optics what so ever, and keep the optics selection to FFP, mil/mil, and perhaps under 20 max mag.

Story 1)
The Fluke corp was designing synthesizers ~1988, and the Fluke marketing department said that the Hewlett Packard name [the competition] on the front of a synthesizer added $1500 in value to the customer.

Story 2)
In 1993 at a medical company I had to work with a $50k HP4284 RLC meter.
HP had simply taken a Japanese instrument and put their name on it [OEM]. The manual was so bad I had to write an in house manual for it.

Story 3)
When Rolls-Royce split up and was sold off, the name was worth more than the companies.

What does it all mean?
When you are only paying for the name, you can get screwed.
I bought an Unertl scope for $14 becuase of the name.

You're either an 1) engineer, 2) actuarian, or 3) accountant. If you enjoy shooting, you're most likely #1.

Arguably, German optics clarity is best - but you'll find the same statistical trend if you factor German origin as your variable. Hence, the lower cost for 34mm tube from USO.
Thanks for posting something only a nerd can appreciate.

What's wrong with accountants? I break the old accountant stereotype (coke-bottle glasses, alergic to everything, high-pitched whiny voice, has loads of money, etc.) by also being a personal trainer, being in the army, and enjoying the rougher things in life (GUNS!).
