The numbers driving this calculator come from years of working with and auditing law firm advertising accounts across Google Ads, Meta, and Local Service Ads — with deep specialization on the injury side. If your real numbers are tracking 30%+ below this projection, the gap is almost always fixable: intake response time, ad-to-landing-page match, untracked phone calls, or CPL benchmarks borrowed from non-legal industries.
