How this calculator works

The three price levels are the lower quartile, median and upper quartile of 72 monthly figures UK SEO firms publish on their own pages, read from 64 sources' own pages on 2026-10-31, every row and its source here. (UK SEO Retainer Price Index)
Prices are as published, usually before VAT. Firms that publish no price are counted in the index as not published, never estimated.
