What is the mathematical formula for Return on Investment (ROI)?

The standard formula for simple ROI is: ROI (%) = [(Total Final Value − Initial Cost) ÷ Initial Cost] × 100. For example, if you invest $10,000 and receive $15,000, your net profit is $5,000, and your ROI is ($5,000 ÷ $10,000) × 100 = 50.0%.

What is the difference between simple ROI and Annualized ROI?

Simple ROI tells you the total percentage gain regardless of how long the investment was held. Annualized ROI (or Compound Annual Growth Rate - CAGR) measures the geometric annual growth rate per year: Annualized ROI = [(Ending Value ÷ Starting Value)^(1/t) − 1] × 100. A 50% simple return earned over 1 year is extraordinary (50% CAGR), whereas a 50% simple return earned over 10 years is modest (~4.14% CAGR).

What is considered a good ROI in business and investing?

Benchmark returns vary by risk profile: The stock market (S&P 500) has historically averaged ~10% annual nominal return (~7% inflation-adjusted); commercial real estate syndications target 12%–18% annual IRR; high-yield savings/CDs yield 4%–5%; and digital advertising campaigns aim for 200%–400% ROI (2x to 4x ROAS).

How to Calculate Return on Investment: Core Formulas & Dynamics

Return on Investment (ROI) evaluates the profitability and efficiency of capital allocation. While simple ROI measures total absolute return percentage, Annualized ROI (CAGR) normalizes for holding time to enable direct comparison across stocks, real estate syndications, venture equity, and marketing campaigns.

1. Simple ROI Formula

ROI (%) = [(Proceeds + Cashflow − Cost) ÷ Cost] × 100

Useful for short-term trades, marketing campaigns, and single-year assets.

2. Annualized ROI (CAGR) Formula

CAGR (%) = [(Final Value ÷ Cost Basis)^(1 ÷ Years) − 1] × 100

Compounds gains geometrically. Essential for multi-year investments.
