Detailed Overview
Return on Investment Calculator measures whether a marketing or capital campaign earned more than it cost. From your investment and your returns it works out the ROI percentage, the annualized ROI for multi-year projects, the net profit gain and the benefit-to-cost ratio, so you can compare campaigns on the same footing.
To use it, enter the total amount invested and the total return, along with the time period if you want an annualized figure. Compare campaigns by annualized ROI rather than raw ROI when they ran for different lengths of time, since a campaign that took three years to earn a return is not the same as one that earned it in three months.
Check that your cost figure is complete. Ad spend alone is rarely the whole investment: staff time, agency fees, tool subscriptions and discounts given to win the sale all belong in the cost, and leaving them out inflates the ROI. Be equally careful with the return, and count only revenue that the campaign actually caused.
One honest limitation: the result is only as honest as its inputs. Attribution is often uncertain, especially when several campaigns run at once, and the tool cannot prove that a campaign caused a sale, so treat ROI as a comparison aid, not as financial advice or proof of what to invest in next.
