About SEO ROI Calculator

Return on investment restates profit as a percentage of the money put in, so a small campaign and a large one can be ranked on the same scale. The return multiple is the gross figure (revenue ÷ cost) that marketing teams usually call ROAS. A SEO programme can grow revenue and still destroy value; ROI is what tells you which side of the line you are on before you scale the spend.

Formula
