The cabinets, countertops, and floor in one house can cost more or less than the same items in another. The difference may be based on a number of factors from difficulty of demolition to region of the country see Regional Cost Adjustments, p. 86. For these reasons, I often use the following charts to project the initial cost of a kitchen remodel at the first meeting with new clients see The Checklist How to Use It, p. 80.
When I arrive at an estimated cost for the potential remodel, we compare it with the client's budget. If we're over budget and the client can't or doesn't want to spend more money, we take a look at each item and try to cut costs. If the estimate is less than anticipated, we may consider upgrades, or the client simply may appreciate the savings.
