💡 Key Metrics Explained

💰 Cash Flow

Cash flow is your monthly profit after all expenses.

👉 Formula:
Rental Income − Expenses = Cash Flow

Positive cash flow:
👉 You make money each month

Negative cash flow:
👉 You lose money each month

📈 ROI (Return on Investment)

ROI measures your total return relative to your investment.

👉 Formula:
ROI = (Annual Profit ÷ Total Investment) × 100

Higher ROI:
👉 Better investment performance

📊 Cap Rate

Cap rate measures income relative to property value.

👉 Formula:
Cap Rate = (Net Operating Income ÷ Property Value) × 100

Used to compare properties quickly.

📊 What is a Good Investment Property?

A good rental property typically has:

• Positive cash flow
• Strong ROI (7%–12%+)
• Cap rate between 5%–10%
• Low vacancy risk
• Growth potential

A rental property calculator helps identify these factors.

📊 Vacancy Rate Explained

Vacancy rate accounts for periods when the property is not rented.

Example:

• 5% vacancy
  👉 Property is empty ~18 days per year

Ignoring vacancy can lead to overestimating income.

📊 Expenses to Include

Always include all expenses:

• Maintenance
• Property taxes
• Insurance
• Property management fees
• Repairs
• Utilities (if applicable)

👉 Accurate inputs = accurate results

📊 Financing and Leverage

If you use a loan:

• Monthly payments reduce cash flow
• Leverage can increase ROI
• Interest affects profitability

A rental property calculator helps balance these factors.

📊 Property Appreciation

In addition to rental income, properties may increase in value over time.

This adds:

• Long-term profit
• Equity growth

👉 Appreciation can significantly boost total returns.

📊 Positive vs Negative Cash Flow

Positive Cash Flow

• Income exceeds expenses
• Generates monthly profit

Negative Cash Flow

• Expenses exceed income
• Relies on appreciation or strategy

👉 Both can work depending on your investment goals.

⚠️ Common Mistakes to Avoid

1. Ignoring Expenses

Always include all costs.

2. Overestimating Rent

Use realistic rental estimates.

3. Ignoring Vacancy

Vacancy reduces income.

4. Focusing Only on Appreciation

Cash flow is just as important.
