Stock Return / ROI Calculator
Return on invested capital for a completed or planned outcome.
How the calculation works
ROI compares profit to capital deployed: (returned − invested) ÷ invested × 100. Returned should be what you get back (sale proceeds, etc.); invested should be what you put in. The profit field is simply returned minus invested.
Formula & example
ROI % = (returned − invested) ÷ invested × 100
Invest $5,000, receive $5,750 → profit $750, ROI 15%.
Why use this calculator
A $500 win on $2,000 committed is different from a $500 win on $50,000. ROI normalizes outcomes so capital efficiency is visible.
When to use it
Use when comparing efficiency across trades or investments of different dollar sizes, after you know invested and returned amounts.
Background
Return on investment is a standard managerial and accounting performance ratio used since at least the early 20th century in business analysis; traders reuse the same simple form for a single completed capital commitment.
Tips for accurate results
- Include fees in invested or returned for net ROI.
- Time-weighted returns need a different model.
FAQ
Is ROI annualized?
No. This is a simple return on the capital figures you enter, not annualized.
