LawyerCostGuide publishes independently researched attorney fee data across 12 practice areas and 161 US cities. This page documents exactly how every price estimate on this site is calculated, which sources we used, and how we maintain data integrity over time.
Step 1 — National baseline. For each practice area we establish a national baseline cost from multiple published industry sources (listed below). We use the midpoint of published ranges as the baseline, not outlier estimates.
Step 2 — City adjustment. Each city price is calculated by multiplying the national baseline by that city's BLS Regional Price Parity index, divided by 100. For example, Los Angeles has a COL index of 127 — so an attorney fee with a national baseline of $10,000 becomes $12,700 in Los Angeles. The BLS RPP index is the same dataset used by the US federal government to measure purchasing power across metro areas.
Step 3 — Quarterly review. All estimates are reviewed quarterly against new survey data and updated where material changes are identified. The review date is displayed on every page.
Independence guarantee. No law firm, attorney, or commercial partner can pay to influence any cost estimate on this site. Our revenue comes from display advertising and lead generation — both of which are completely separate from our data research function.
Each practice area uses a minimum of three independent published sources as the basis for its national baseline estimate.

The Bureau of Labor Statistics publishes Regional Price Parity (RPP) indices annually for all US metropolitan areas. An RPP of 100 represents the national average cost of living. An RPP of 127 (Los Angeles) means goods and services in that city cost 27% more than the national average.
We use RPP indices because they are the most rigorous publicly available dataset for comparing purchasing power across US cities. They are the same indices used by the US federal government, academic researchers, and the Congressional Budget Office for cost-of-living comparisons.
Attorney fees track RPP indices closely because the primary cost inputs for legal practice — office space, staff salaries, malpractice insurance premiums — all correlate with local cost of living.
We make every effort to ensure price estimates are accurate and current. If you believe any estimate is materially incorrect, contact us and we will review within 5 business days. We update all data quarterly and display the review date on every page.
All estimates are ranges, not guarantees. Actual attorney fees depend on the specifics of your case, the attorney you retain, and local market conditions at the time of engagement. Always obtain at least three quotes from licensed attorneys before making any decision.
