How we estimate costs
Every figure on this site is an estimate built from published fee norms and government cost-of-living data. Here is exactly how we arrive at the numbers — and where the data comes from.
The formula
Each estimate is a national fee benchmark for the service, multiplied by the local cost-of-living index for your ZIP code. Every area carries an index where 100 equals the U.S. average: a ZIP at 130 sees figures about 30% higher than the national norm, and a ZIP at 90 sees figures roughly 10% lower. We publish a Low, Average, and High benchmark for each service and scale all three.
Where the cost benchmarks come from
National Low / Average / High figures reflect typical U.S. price ranges for each service — drawn from published industry cost guides, contractor pricing data, and prevailing market rates. The Low figure reflects a smaller or basic-finish job, the High a larger or premium one, and the Average the typical middle case, all before any local adjustment is applied.
Where the local adjustment comes from
The cost-of-living index is derived from the most precise source available for each ZIP code:
- Metro & state price levels — U.S. Bureau of Economic Analysis Regional Price Parities (RPP), which measure how local prices compare to the national average.
- ZIP → metro mapping — U.S. Census Bureau metropolitan/micropolitan geography, so each ZIP is matched to its correct metro area.
- ZIP geolocation — open postal data resolves a ZIP to its city, state, and metro before the index is applied.
When metro-level data isn't available for a ZIP, we fall back to the state index, then to the national average.
What the estimates are — and aren't
These figures are informational estimates, not quotes or legal advice. Your actual fee depends on the pro, the complexity and stage of your case, and the engagement terms you sign. For an exact price, speak with a licensed pro in your area.
