Rental House Calculator
A Rental House Calculator helps you determine how much income and profit you can make from renting out a house.
It factors in:
- Monthly rent
- Mortgage payments
- Maintenance costs
- Taxes and insurance
- Vacancy rates
With just a few numbers, it shows your cash flow, ROI, and net income — so you know exactly how profitable your rental house will be.
🧮 How the Rental House Calculator Works
This calculator uses three main formulas:
1️⃣ Gross Monthly Income
Rent × Number of Units
2️⃣ Net Operating Income (NOI)
Gross Income – Operating Expenses
3️⃣ Cash Flow
NOI – Mortgage Payments
Example:
- Rent: $1,800/month
- Expenses: $600/month
- Mortgage: $900/month
Calculation:
- NOI = $1,800 – $600 = $1,200
- Cash Flow = $1,200 – $900 = $300 profit/month
💰 Result: You earn $300 every month after expenses!
