🧾 Rental Return Formulas (Plain Text)
1. Net Operating Income (NOI):
NOI = Gross Rental Income – Operating Expenses
2. Cash Flow:
Cash Flow = NOI – Mortgage Payments
3. Total Return on Investment (ROI):
ROI = (Annual Profit ÷ Total Initial Investment) × 100
4. Cap Rate:
Cap Rate = (NOI ÷ Property Price) × 100
5. Cash-on-Cash Return:
Cash-on-Cash = (Annual Cash Flow ÷ Total Cash Invested) × 100
📊 Example: Return on Rental Property Investment
Let’s say you’re evaluating a $250,000 rental property.
| Item | Value |
|---|---|
| Purchase Price | $250,000 |
| Down Payment | $50,000 |
| Loan Amount | $200,000 |
| Interest Rate | 6% |
| Loan Term | 30 years |
| Monthly Rent | $2,000 |
| Monthly Expenses | $500 |
| Vacancy Rate | 5% |
Step-by-Step Calculation:
Monthly Mortgage Payment ≈ $1,199.10
Vacancy Loss = $2,000 × 5% = $100
Net Monthly Income = $2,000 – $500 – $100 – $1,199.10 = $200.90
Annual Profit = $200.90 × 12 = $2,410.80
ROI = ($2,410.80 ÷ $50,000) × 100 = 4.82%
NOI = ($2,000 – $500) × 12 = $18,000
Cap Rate = ($18,000 ÷ $250,000) × 100 = 7.2%
Cash-on-Cash Return = ($2,410.80 ÷ $50,000) × 100 = 4.82%

❓ 20 Frequently Asked Questions (FAQs)
1. What is a good ROI for rental property?
An ROI of 8–12% is generally considered solid, though it depends on location and risk profile.
2. How often should I calculate my returns?
At least annually, or whenever income or expenses change.
3. What if I buy the property in cash?
Just exclude loan details. Your ROI and cash-on-cash return will be the same.
4. Can I include appreciation in return calculation?
Appreciation is a separate form of return (equity gain), not included in operational ROI.
5. What’s the difference between ROI and Cap Rate?
ROI includes your total investment and financing. Cap rate uses property value and NOI only.

It measures your return based only on the cash you’ve invested (e.g., down payment).
7. Can I use this for multifamily or commercial properties?
Yes, just sum up income and expenses across all units.
8. Should I include depreciation?
No, depreciation is a tax consideration—not a cash expense—so it’s excluded from these returns.

Your ROI will be inflated, leading to bad investment decisions. Use conservative estimates.
10. What expenses should I include?
Taxes, insurance, utilities (if applicable), maintenance, repairs, and management fees.

You can skip management fees, but remember your time has value.
15. Can I use estimated numbers?
Yes, but try to be conservative to avoid underperformance.
16. What’s the Payback Period?
It’s how long it takes to recover your initial investment. = Initial Investment ÷ Annual Cash Flow.
17. Does the calculator support refinancing scenarios?
You can manually input new loan terms to see how refinancing affects returns.
18. What if I get a lower mortgage rate later?
Lower payments will increase cash flow and improve ROI.
19. Are utilities included in the expenses?
Yes, if paid by the landlord.
