📐 Rental Property Profit Formulas (Plain Text)
Here are the main formulas used in the calculator:
1. Net Operating Income (NOI)
NOI = Rental Income – Operating Expenses
2. Cash Flow (Profit)
Cash Flow = Rental Income – (Operating Expenses + Mortgage Payment + Vacancy Loss)
3. Return on Investment (ROI)
ROI = (Annual Profit ÷ Total Investment) × 100
4. Capitalization Rate (Cap Rate)
Cap Rate = (NOI ÷ Property Value) × 100
🧾 Example: Rental Property Profit Calculation
Let’s walk through an example:
| Item | Monthly Amount |
|---|---|
| Rental Income | $2,000 |
| Property Taxes | $150 |
| Insurance | $100 |
| Maintenance | $100 |
| Property Management | $160 |
| Mortgage Payment | $900 |
| Vacancy Rate | 5% |
| Property Value | $250,000 |
| Down Payment (Investment) | $50,000 |
Step 1: Calculate Operating Expenses
Total Expenses = $150 + $100 + $100 + $160 = $510
Step 2: Vacancy Loss
Vacancy = $2,000 × 5% = $100
Step 3: Cash Flow
Net Cash Flow = $2,000 – ($510 + $900 + $100) = $490/month
Step 4: Annual Profit
Annual Profit = $490 × 12 = $5,880
Step 5: ROI
ROI = ($5,880 ÷ $50,000) × 100 = 11.76%
Step 6: Cap Rate
NOI = $2,000 – $510 = $1,490/month = $17,880/year
Cap Rate = ($17,880 ÷ $250,000) × 100 = 7.15%

1. What is a good ROI for a rental property?
Generally, an ROI of 8–12% is considered good, but it depends on your market and goals.
2. What’s the difference between NOI and cash flow?
NOI excludes mortgage payments; cash flow includes them.
3. Should I include property appreciation in profit?

Depreciation impacts taxes, not cash flow. It’s not included in this calculator.
7. What’s the difference between gross and net profit?
Gross profit is rent minus direct expenses. Net profit subtracts mortgage and vacancy costs.
8. Does the calculator factor in taxes?
Only property taxes. Income tax should be calculated separately.

Increase rent, reduce expenses, or refinance at a lower rate.
18. How do I calculate profit if the property is paid off?
Your profit = rent – operating expenses and vacancy loss (no mortgage payment).
19. Is positive cash flow the same as profit?
Yes, in most cases. But be sure to factor in all costs for true profitability.
20. What’s the risk of ignoring this calculation?
You could buy a property that drains money instead of making it. Always know your numbers.
