How an ROI Calculator Works
Basic ROI Formula
Where:
Net Profit = Final Value - Initial Investment
Investment Cost = Initial Amount Invested
Example Calculation
| Input | Value |
|---|---|
| Initial Investment | $10,000 |
| Final Value | $15,000 |
| ROI | 50% |
Calculation:
Key Inputs Required
Initial Investment – Amount originally invested.
Final Value – Current or sold value of the investment.
Holding Period (Optional) – Timeframe to calculate Annualized ROI.
Additional Costs (Optional) – Fees, taxes, or maintenance expenses.
Types of ROI Calculations
| Type | Formula | Use Case |
|---|---|---|
| Simple ROI | (Gain - Cost) / Cost | Quick profitability check |
| Annualized ROI | [(1 + ROI)^(1/n) - 1] × 100% | Compare investments over different time periods |
| Adjusted ROI | (Gain - Cost - Fees) / Cost | Accounts for extra expenses |
Why ROI Matters
✅ Compare Investments – Stocks vs. real estate vs. business ventures.
✅ Measure Success – Evaluate marketing campaigns, projects, or asset purchases.
✅ Decision-Making – Identify high-performing vs. underperforming assets.
Limitations of ROI
⚠ Ignores Time – A 50% ROI over 1 year is better than over 10 years.
⚠ No Risk Adjustment – Doesn’t account for volatility or risk level.
⚠ Excludes External Factors – Inflation, taxes, or opportunity costs.
