Rental Investment Calculator

A Rental Investment Calculator helps you determine whether a rental property is a good investment by estimating cash flow, ROI (Return on Investment), cap rate, and overall profit.

It combines all the key financial factors — income, expenses, mortgage, and taxes — so you can see your true returns before making a purchase or refinancing decision.

Perfect for landlords, real estate investors, and anyone exploring passive income through property.

🧮 How the Rental Investment Calculator Works

This calculator turns your property numbers into clear financial insights.

Formula #1 – Cash Flow:

Cash Flow = Rental Income – (Operating Expenses + Loan Payments)

Formula #2 – ROI (Return on Investment):

ROI = (Annual Cash Flow ÷ Total Investment) × 100

Formula #3 – Cap Rate:

Cap Rate = (Net Operating Income ÷ Property Value) × 100

Formula #4 – Cash-on-Cash Return:

Cash-on-Cash = (Annual Cash Flow ÷ Cash Invested) × 100

📊 Example: Calculating ROI

Let’s say:

• Purchase price: $300,000
• Down payment: $60,000 (20%)
• Monthly rent: $2,200
• Monthly expenses: $400
• Mortgage payment: $1,200

Monthly cash flow: $2,200 – ($1,200 + $400) = $600
Annual cash flow: $600 × 12 = $7,200

ROI = ($7,200 ÷ $60,000) × 100 = 12%

✅ Your investment earns 12% ROI per year — a strong return!
