ROI Calculator
Compute ROI — the simple ratio of net profit to investment cost. Accepts negative ROI for losses. Clearly shows gain/loss amount and percentage. The underlying formula is: ROI = ((Final Value − Initial Investment) / Initial Investment) × 100 — where ROI measures the net profit or loss relative to the original investment cost. A positive ROI indicates a gain; negative indicates a loss.
Whether you are facing an important financial decision or simply need a fast, reliable answer, this calculator eliminates manual mathematical errors and delivers instant, accurate results. It is designed around verified industry standards and mathematical best practices, making it suitable for students, professionals, and everyday users alike.
Use the inputs above to enter your values — results update in real time. Below the result, you will find a step-by-step formula breakdown, a worked numerical example, and common mistakes to avoid.

Practical Worked Example for ROI Calculator
Suppose you want to compute roi calculator with standard baseline inputs.
Example Baseline Inputs:
Step-by-Step Mathematical Solution:
- 1Initial Investment = ₹1,00,000
- 2Final Value = ₹1,20,000
- 3Net Profit = 120000 − 100000 = 20000.00
- 4ROI = (20000.00 / 100000) × 100 = 20.00%
