Overview
The ROI (Return on Investment) calculator measures the gain or loss on an investment relative to its cost, expressed as a percentage. It also calculates the annualised return (CAGR) for multi-year investments.
How to use this calculator
- Enter the initial investment amount (cost).
- Enter the final value of the investment (current or exit value).
- Enter the holding period in years (for annualised return).
- The calculator shows ROI %, total profit/loss, and annualised return (CAGR).
Understanding the inputs & results
Initial investment
The amount invested at the beginning — the cost basis.
Final value
The current or selling price of the investment.
ROI (%)
Return on Investment — net profit divided by cost, expressed as a percentage.
CAGR
Compound Annual Growth Rate — the annualised rate at which the investment grew, assuming compounding.
Net profit
Final value minus initial investment. Can be negative (a loss).
The formula
ROI and CAGR
ROI = (Final − Initial) / Initial × 100 | CAGR = (Final / Initial)^(1/years) − 1
ROI measures total percentage gain. CAGR normalises the return per year, making it comparable across investments of different durations.
Worked example
Invested ₹1,00,000; current value ₹1,80,000 after 4 years.
- ROI = (1,80,000 − 1,00,000) / 1,00,000 × 100 = 80%.
- CAGR = (1,80,000 / 1,00,000)^(1/4) − 1 = (1.8)^0.25 − 1 ≈ 15.83% p.a.
✓ Total ROI = 80%. Annualised return (CAGR) ≈ 15.83% p.a.
Frequently asked questions
ROI is a backward-looking metric. Past returns do not guarantee future performance. Consult a financial advisor for investment decisions.
