Free ROI Calculator: How To Calculate Return On Investment
ROI — or Return on Investment — tells you how much value you gained compared to what you spent. It’s typically expressed as a percentage, and it helps you figure out whether a decision was worthwhile, and how different options stack up.
How ROI Works
The formula is simple:
Net profit is just the difference between what you earned and what you spent. For example, if you invest $5,000 in something and it returns $6,000, your net profit is $1,000. Divide that by the cost ($5,000), and you get 0.2 — or 20% ROI.
Why It’s So Widely Used
- ✅ It’s easy to understand and communicate
- ✅ It works across departments and industries
- ✅ It lets you compare very different projects side by side
- ✅ It highlights whether something is worth doing at all

What’s a Good ROI?
| ROI Range | Interpretation |
|---|---|
| 100% and above | Excellent — strongly profitable |
| 50% to 99% | Solid return — likely exceeds inflation |
| 0% to 50% | Minimal return — maybe just breaking even |
| Below 0% | Loss — time to reassess |

Final word: If it uses AI, how do I know I can trust it?
Trust doesn't come from hiding the AI. It comes from showing exactly what it's doing. That's why Reschematic reveals every assumption, lets you trace how each number was calculated, and gives you full control to make changes. It works like a spreadsheet in terms of transparency, but without the complexity. You get speed and credibility, together.
