Key Real Estate Formulas
1. Return on Investment (ROI)
Return on Investment (ROI) is a crucial metric used to evaluate the profitability of an investment. It measures how much profit an investment generates relative to its cost.
Formula:
\[ \text{ROI} = \left( \frac{\text{Net Profit}}{\text{Total Investment}} \right) \times 100 \]
Example:
- Total Investment: $200,000
- Net Profit: $50,000
\[ \text{ROI} = \left( \frac{50,000}{200,000} \right) \times 100 = 25\% \]
2. Capitalization Rate (Cap Rate)
The Capitalization Rate helps investors assess the potential return on an investment property based on its income-generating ability.
Formula:
\[ \text{Cap Rate} = \left( \frac{\text{Net Operating Income (NOI)}}{\text{Current Market Value}} \right) \times 100 \]
Example:
- NOI: $30,000
- Market Value: $400,000
\[ \text{Cap Rate} = \left( \frac{30,000}{400,000} \right) \times 100 = 7.5\% \]
3. Gross Rent Multiplier (GRM)
The Gross Rent Multiplier is a simple tool for estimating the value of a rental property based on its gross rental income.
Formula:
\[ \text{GRM} = \frac{\text{Property Price}}{\text{Gross Annual Rent}} \]
Example:
- Property Price: $300,000
- Gross Annual Rent: $30,000
\[ \text{GRM} = \frac{300,000}{30,000} = 10 \]
Financing Formulas
4. Monthly Mortgage Payment
Understanding how to calculate monthly mortgage payments is vital for both home buyers and investors.
Formula:
\[ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} \]
Where:
- \( M \) = monthly payment
- \( P \) = principal loan amount
- \( r \) = monthly interest rate (annual rate / 12)
- \( n \) = number of payments (loan term in months)
Example:
- Principal: $200,000
- Annual Interest Rate: 5%
- Loan Term: 30 years
Convert the interest to a monthly rate:
\[ r = \frac{5\%}{100} \div 12 = 0.004167 \]
Calculate:
\[ n = 30 \times 12 = 360 \]
\[ M = 200,000 \times \frac{0.004167(1 + 0.004167)^{360}}{(1 + 0.004167)^{360} - 1} \approx 1,073.64 \]
5. Debt Service Coverage Ratio (DSCR)
The Debt Service Coverage Ratio measures a property's ability to generate enough income to cover its debt obligations.
Formula:
\[ \text{DSCR} = \frac{\text{Net Operating Income (NOI)}}{\text{Debt Service}} \]
Example:
- NOI: $50,000
- Debt Service: $30,000
\[ \text{DSCR} = \frac{50,000}{30,000} \approx 1.67 \]
Investment Analysis Formulas
6. Cash Flow
Cash flow is the net amount of cash being transferred into and out of a property investment, indicating its profitability.
Formula:
\[ \text{Cash Flow} = \text{Total Income} - \text{Total Expenses} \]
Example:
- Total Income: $60,000
- Total Expenses: $40,000
\[ \text{Cash Flow} = 60,000 - 40,000 = 20,000 \]
7. Net Operating Income (NOI)
NOI is a key figure in real estate that reflects the income generated from a property after operating expenses are deducted.
Formula:
\[ \text{NOI} = \text{Gross Income} - \text{Operating Expenses} \]
Example:
- Gross Income: $100,000
- Operating Expenses: $30,000
\[ \text{NOI} = 100,000 - 30,000 = 70,000 \]
8. Property Appreciation
Property appreciation is the increase in the value of a property over time, an important factor for long-term investors.
Formula:
\[ \text{Appreciation Rate} = \left( \frac{\text{Current Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100 \]
Example:
- Current Value: $350,000
- Original Value: $300,000
\[ \text{Appreciation Rate} = \left( \frac{350,000 - 300,000}{300,000} \right) \times 100 \approx 16.67\% \]
Understanding Real Estate Metrics
9. Price Per Square Foot
This metric helps buyers and sellers understand property value in relation to its size.
Formula:
\[ \text{Price Per Square Foot} = \frac{\text{Property Price}}{\text{Total Square Feet}} \]
Example:
- Property Price: $400,000
- Total Square Feet: 2,000
\[ \text{Price Per Square Foot} = \frac{400,000}{2,000} = 200 \]
10. Equity
Equity represents the ownership value in a property, which can be crucial for refinancing or selling.
Formula:
\[ \text{Equity} = \text{Current Market Value} - \text{Remaining Mortgage Balance} \]
Example:
- Current Market Value: $500,000
- Remaining Mortgage Balance: $300,000
\[ \text{Equity} = 500,000 - 300,000 = 200,000 \]
