Every investment decision — whether buying a rental property in Australia, investing in an S&P 500 index fund in the USA, starting a business in the UK, or purchasing bonds in Canada — comes down to one question: what will my return on investment be? This guide shows you how to calculate investment ROI for any asset class accurately, using our free ROI Calculator.

How to Calculate ROI on Stock Investments
Stock ROI = [(Current Value + Dividends − Purchase Price − Fees) / Purchase Price] × 100
Example: You buy 200 shares of a US stock at $45 each ($9,000 total). 3 years later, they're worth $68/share ($13,600). You received $450 in dividends. Brokerage fees: $25.
- Total return: $13,600 + $450 − $9,000 − $25 = $5,025
- Total ROI: ($5,025 / $9,000) × 100 = 55.8%
- CAGR: ($14,050/$9,000)^(1/3) − 1 = 16.05% annually
How to Calculate ROI on Real Estate
Real estate ROI has two components: rental yield and capital appreciation.
Cash-on-Cash ROI = Annual Net Cash Flow / Cash Invested × 100
Example (Australian property):
- Property: AUD $600,000 | Down payment: $120,000 (20%) | Closing costs: $25,000
- Total cash invested: $145,000
- Annual rent: $28,800 ($2,400/month)
- Annual expenses (mortgage interest, tax, insurance, management, maintenance): $22,500
- Net cash flow: $28,800 − $22,500 = $6,300
- Cash-on-Cash ROI = ($6,300 / $145,000) × 100 = 4.34%
- Plus 3% annual appreciation on $600,000 = $18,000 additional equity/year
- Total annual return: ($6,300 + $18,000) / $145,000 = 16.8% on cash invested
The Power of Leverage in Real Estate ROI
Real estate is unique because you control a $600,000 asset with only $145,000 cash (80% leverage). If the property appreciates 5%, that's $30,000 in asset value on $145,000 cash = 20.7% return on cash invested, even though the asset only grew 5%. This amplification makes real estate one of the most powerful wealth-building tools for middle-income earners in the USA, Canada, UK, and Australia.
