What Is This Tool?
This ROI Calculator helps you figure out how good (or bad) a result really was. You enter what you spent and what you got back, and the tool gives you your ROI percentage along with the profit. It’s a quick way to stop guessing and see the outcome clearly.
How This Tool Works (Simple Explanation)
It follows one standard formula:
- Profit = Return − Cost
- ROI % = (Profit ÷ Cost) × 100
- The tool shows both ROI and profit so you can understand the result fast.

Step-by-Step How to Use
- Enter the Investment Cost (what you spent).
- Enter the Total Return (what you received back).
- Choose your currency (optional, just for display).
- Click Calculate to see profit and ROI %.

FAQs
1) What does ROI tell me?
ROI shows how much you gained (or lost) compared to what you spent, as a percentage.
2) What if ROI is negative?
That means you got back less than you spent, so the result was a loss.
3) Should I enter revenue or profit in “Return”?
Enter the total amount you received back (revenue/return). The tool calculates profit automatically.
4) Why can’t cost be zero?
ROI requires dividing by cost. If cost is zero, the percentage doesn’t make sense — use profit instead.
5) Is ROI enough for long-term projects?
ROI is great for quick comparison, but for time-based projects, IRR/NPV gives deeper detail.
6) Can I use this for marketing?
Yes — use total spend as cost and total return as return. If you want ad-specific metrics, you can also track ROAS separately.
