How we estimate this
Every figure on this page is compiled from the public sources cited above and given as a low–typical–high range rather than a single false-precise number. Where costs vary by location we scale the national typical using published state price levels. We recheck figures on a set schedule and stamp each report with the date last verified. We are independent and are never paid to change a number — see how we price things.
