What Is a Property Rental Calculator?

A Property Rental Calculator is an online financial tool that helps you estimate your rental property’s potential profit and performance.

• Annual rental income
• Operating expenses
• Net operating income (NOI)
• Return on investment (ROI)
• Cap rate (capitalization rate)

Essentially, it shows you how much money you’ll earn or lose from renting out a property.

Example: Real-World Property Rental Calculation

Let’s see how the calculator works in practice.

Example Property:

• Purchase Price: $200,000
• Down Payment: $40,000
• Loan Amount: $160,000
• Interest Rate: 5%
• Loan Term: 25 years
• Monthly Rent: $1,800
• Monthly Expenses: $500
• Vacancy Rate: 5%

Step 1: Annual Rental Income

$1,800 × 12 = $21,600
Minus 5% vacancy = $20,520

Step 2: Annual Expenses

$500 × 12 = $6,000

Step 3: Net Operating Income (NOI)

$20,520 – $6,000 = $14,520

Step 4: ROI Calculation

ROI = (Net Income ÷ Total Investment) × 100
= ($14,520 ÷ $40,000) × 100 = 36.3% ROI

✅ Result: This property is a great investment with a solid return and healthy cash flow.
