A bit cryptic on the question - I assume you are talking about well cost - or perhaps well water system cost ?

Generally it is recommended a normal house have a minimum 6-12 gpm flow capacity, preferably 10 gpm if feasible (because a shower or washer can pull 5 gpm alone) - which can come directly from the well itself or from a storage tank system with booster pump which is kept filled by pumping from a lower-yield well. Obviously, simpler and cheaper if the well itself can yield that but mother nature does not always cooperate.

Total daily well capacity (during dry season) should normally be around at least 100 gpd (gallons per day) per person PLUS anticipated irrigation/lawn watering demand, and even that can result in shortages or the well being pumped dry during periods of high use (which is a bad thing). Generally, sustained well yields under about 3 gpm (4000 gpd) are considered to be very iffy and less than desireable, and a common guideline is it should be able to yield a sustained 5 gpm for 2 hours - which may be achieved by using a storage tank system. (Federal guaranteed loans from HUD require 3 gpm well production for 4 continuous hours, for instance - 5 gpm for proposed new construction). Different areas and designers and lenders use different numbers but those are some ballparks. If a storage tank is required because of low well gpm capacity, minimum 500 gallons is a common number for a normal siae household.

How deep depends so much on whether you are in a natural aquifer or floodplain or up on a hill, so wells within a mile radius or less in normal hilly or rolling country can commonly vary from a few dozen feet or hundreds in depth, depending on the groundwater depth, aquifer permeability and porosity, any local water quality issues like oil or natural gas or coal or salt or such, etc. Asking the neighbors what their well capacity and depth is might give you not only a ballpark idea (taken with a grain of salt because most people do not really know those numbers) and also get some contractor word-of-mouth recommendations.

Cost can commonly run from bare minimum about $1000-2000 range for very shallow or artesian (water at the surface) well to more around $3000-5000 commonly for normal wells (say up to 50 feet) to as much as $100,000 or more for areas where very deep wells are needed. I have been involved in several cases in oilfield areas and also one in your area in a saltdome area near Detroit where it ran over $250,000 and required a well well over 3000 feet deep, though those are rare cases !

The equipment/piping/controls for the well water system commonly runs another $1000-2000 in most cases for wells fairly near the house - which of course can increase with long piping runs because of depth of burial needed (like in your deep frost penetration area, because water is not hit at reasonable depth near the house (say on a ridge or hilltop versus shallower water lower on the property or near a drainage), or because the well has to be located at a remote part of the lot because of nearby wells or septic systems or surface contamination from industrial activity or livestock runoff or pesticide/fertilizer contamination or such.

Plus in probably most well served areas you will need a water treatment system of around $1000-2000 for simple salt-based water softener, to sometimes as much as $2000-5000 range depending on the contaminants or minerals which need to be treated for. Rarely, but in areas of chemical or petroleum contamination can run as much as $5000-10,000 to get decent quality water, though in many such cases the owner chooses a cheaper system to get to acceptable washing/bathing quality water and using bottled water or a dedicated small capacity treatment system for drinking and cooking water.

Your best bet is to talk to several well-rated and reviewed local Wells and Pumps (your Search the List category) about typical costs in your area.
