How to calculate return on investment

  1. 1

    Enter the amount invested

    The total you put in: a purchase price, ad spend, equipment cost or project budget.

  2. 2

    Enter the amount returned

    What the investment is worth now or the revenue it brought in.

  3. 3

    Add other costs

    Include fees, maintenance or running costs so the ROI reflects everything you spent.

  4. 4

    Add the length for a fair comparison

    Enter how many years it took to see the annualised return, which lets you compare a 1-year and a 5-year investment.

Measure what your money earns

Return on investment answers a simple question: for every unit of money you put in, how much did you get back? Use it to judge equipment purchases, marketing campaigns, hires, stock, property or any project with a cost and a payoff. Adding the time period turns it into an annualised rate, so you can compare options fairly.

Frequently asked questions

What is the ROI formula?

ROI = (amount returned − total invested) ÷ total invested × 100. Investing 10,000 and getting back 15,000 is a profit of 5,000, so the ROI is 50%.

What is the difference between ROI and annualised return?

ROI is the total return over the whole period, however long it was. Annualised return (also called CAGR) spreads it into an equivalent yearly rate: a 50% ROI over 3 years is about 14.5% a year, while 50% in one year is 50% a year.

What is a good ROI?

It depends on the risk and the alternatives. Compare the annualised return with what the money could earn elsewhere, such as a savings account or an index fund. For marketing, many businesses aim for revenue of at least three to five times the ad spend.

How do I calculate marketing ROI?

Use the campaign cost as the amount invested and the gross profit it generated (revenue minus the cost of the goods sold) as the amount returned. Using revenue alone overstates the return.
