What is the ROI Calculator?
Return on investment (ROI) compares what you earned with what you spent. This calculator takes your investment, any other costs and the total return, and shows ROI as a percentage along with net profit and a return multiple.
It is built for marketers, consultants and small business owners judging an ad campaign, a tool, a hire or a project, in rupees, dollars, euros or pounds.
How to use the free ROI Calculator
- Choose a currency: Pick INR, USD, EUR or GBP so the results use the right symbol and number format.
- Enter the investment and other costs: Add the amount invested and any other costs, such as fees or time you paid for.
- Enter the total return: Add the total money earned from the investment.
- Add the time period (optional): Enter the months to see annualised ROI.
- Set a target ROI: Enter the ROI you want, and the tool shows the return needed to reach it.
Example: input and output
A campaign with ₹1,00,000 invested, ₹20,000 other costs, ₹1,80,000 return over 3 months and a 100% target.

Compared on 22 October 2026 by opening each tool and reading its page. Features can change.
What the ROI Calculator cannot do
- ROI ignores timing, risk and the value of money over time.
- Annualised ROI assumes you could repeat the same return all year. On short periods it can look unrealistically high.
- You must work out the total return yourself. The tool does not attribute revenue to a campaign.
- It handles one investment at a time and does not compare channels.

ROI Calculator FAQ
How do I calculate ROI?
ROI equals net profit divided by total cost, times 100. Net profit is your return minus your total cost. For ₹1,20,000 cost and ₹1,80,000 return, ROI is 50%.
What is a good ROI?
It depends on the channel, the margin and the risk. A positive ROI means you earned more than you spent. Set a target that covers your other costs and time.
What is the difference between ROI and ROAS?
ROAS divides revenue by ad spend and ignores other costs. ROI uses profit after all costs. A campaign can have a good ROAS and a poor ROI.
What is annualised ROI?
It scales your return to a 12-month rate. It is a rough guide only and can mislead on short periods.
What is break-even return?
It is the return that equals your total cost, where ROI is zero.
Can I use it for SEO ROI?
Yes. Enter your SEO spend as the investment, the revenue it brought in as the return, and the months. Be careful to count only revenue you can link to SEO.
Is the ROI calculator free?
Yes, it is free and needs no signup.
