What is ROI (Return on Investment)?

Return on Investment (ROI) is the most fundamental metric to measure investment performance. It calculates the percentage gain or loss relative to your initial investment, helping you understand how efficiently your money is working.

Our ROI calculator provides both simple ROI (total return) and CAGR (annualized return), enabling fair comparison between investments held for different time periods.

ROI Calculation Formulas

Simple ROI

ROI = ((Final Value - Initial Investment) ÷ Initial Investment) × 100

CAGR (Compound Annual Growth Rate)

CAGR = ((Final Value ÷ Initial Investment)^(1/Years) - 1) × 100

ROI Calculation Example

Initial Investment₹5,00,000
Final Value (after 5 years)₹8,50,000
Absolute Profit₹3,50,000
Simple ROI70%
CAGR11.2% per year

Why CAGR Matters More Than Simple ROI

Simple ROI doesn't account for time. Consider these two investments:

InvestmentSimple ROIDurationCAGR
Stock A50%2 years22.5%
Stock B50%5 years8.5%
FD40%5 years7.0%

Stock A with 50% ROI in 2 years (22.5% CAGR) vastly outperforms Stock B with same 50% ROI in 5 years (8.5% CAGR). Always use CAGR for comparison.

ROI Benchmarks by Investment Type

InvestmentExpected CAGRRisk Level
Savings Account3-4%Very Low
Fixed Deposits6-7%Low
PPF7.1% (current)Very Low (govt. backed)
Debt Mutual Funds6-8%Low-Medium
Gold8-10%Medium
Large Cap Equity Funds10-12%Medium
Mid/Small Cap Funds12-15%High
Real Estate (Tier 1 cities)8-12%Medium
Direct StocksVaries widelyHigh

Rule of thumb: If an investment promises returns significantly higher than these benchmarks, scrutinize the risk carefully.

Real vs Nominal Returns

Always consider inflation when evaluating ROI:

Real Return ≈ Nominal Return - Inflation Rate

InvestmentNominal ReturnAfter 6% Inflation
Savings Account (3.5%)3.5%-2.5% (losing purchasing power)
FD (7%)7%+1% (barely beating inflation)
Equity Fund (12%)12%+6% (real wealth creation)

ROI for Business Investments

Business investments (equipment, marketing, expansion) need higher ROI to justify the risk and opportunity cost:

  • Marketing ROI - Target 3:1 to 5:1 (300-500% ROI)
  • Equipment purchase - Should pay back within 2-3 years (33-50% annual ROI)
  • New product development - Typically needs 5:1 return to justify R&D risk
  • Business expansion - Minimum 20-25% annual returns expected

Common ROI Mistakes

  1. Ignoring time value - Always convert to CAGR for fair comparison
  2. Forgetting costs - Include brokerage, taxes, maintenance in calculations
  3. Comparing apples to oranges - Don't compare FD ROI with equity ROI without considering risk
  4. Survivorship bias - Failed investments are often forgotten, skewing perception
  5. Not accounting for taxes - Post-tax ROI is what matters for your pocket

Frequently Asked Questions

Can ROI be negative?

Yes, negative ROI means you lost money. A -20% ROI means your ₹1,00,000 investment is now worth ₹80,000. Negative ROI is common in stocks, crypto, and business investments that don't work out.

How do I calculate ROI with dividends?

Include dividends in your final value. If you invested ₹1,00,000, received ₹5,000 dividends, and current value is ₹1,20,000, total return = ₹1,25,000 - ₹1,00,000 = ₹25,000. ROI = 25%.

What's the Rule of 72?

Quick way to estimate doubling time: Years to double = 72 ÷ CAGR%. At 12% CAGR, money doubles in 72÷12 = 6 years. At 8%, it takes 9 years. Useful for quick mental calculations.

Should I use ROI or IRR?

Use ROI/CAGR for single investment, single redemption. For multiple investments at different times (like SIP), use XIRR which accounts for timing of each cash flow and gives accurate annualized returns.
