Who This Calculator Helps
This tool is useful for marketers and founders who need to prove a spend was worth it, plus consultants reporting hard results to clients.
How to measure your return
- Enter the total revenue the investment generated.
- Add the full cost, including fees, labor, and overhead.
- Read your ROI percentage, net return, and return multiple.
- Adjust the figures to test scenarios before you commit.
Planning NoteYour results reflect only the revenue and cost figures you type in, so their accuracy hinges on capturing every expense and correctly crediting revenue to this specific investment. Real outcomes shift with timing, refunds, taxes, indirect overhead, and sales you might have won anyway without the spend, so use the numbers as a guide rather than a guarantee.

Frequently Asked Questions
What does the Investment Return Calculator measure?
It shows how much value a campaign, project, or purchase returned relative to what it cost. You get an ROI percentage, the net dollars gained or lost, and a multiple revealing how many times over the original spend came back.
Who is this calculator built for?
It suits founders sizing up a bet, marketers grading channels, freelancers proving their impact, and agencies reporting outcomes. Anyone deciding whether money was well spent will get a quick, honest read.
How is the ROI figure worked out?
The tool subtracts your total cost from the revenue generated to find the net return, then divides that net return by the cost and shows it as a percentage. The return multiple simply divides revenue by cost, so both outputs move directly with the two numbers you enter.
How far can I trust the ROI figure?
They are only as reliable as what you feed in. Omit hidden costs like your own time, or count revenue the investment did not truly cause, and the percentage will flatter or understate reality, so treat the output as a decision aid rather than an audited number.
Can I use it to compare several investments?
Yes. Run each option through on its own, jot down the ROI and multiple for each, and the choice with the highest return per dollar usually signals where your next budget belongs. It is a fast way to rank competing campaigns or projects.
