Free Investment Property Calculator & Pro Forma Spreadsheet

Analyze Your Real Estate Investments Like a Pro - for Both Short-Term and Long-Term Rentals

Unlock the ultimate Investment Property Calculator Excel Spreadsheet, built to help investors, real estate professionals, and Airbnb/Vrbo hosts make smarter, data-driven decisions. Whether you’re evaluating a beachfront short-term rental or a long-term residential investment, this free, downloadable spreadsheet gives you everything you need to understand your property’s performance before you buy.

What’s Inside the Investment Property Calculator

✔ Dual Analysis: Short-Term & Long-Term Rental Pro Forma

Easily toggle between Short-Term Rental (STR) and Long-Term Rental (LTR) scenarios.

• Short-Term Rental Analysis: Perfect for Airbnb and Vrbo investors. Input your projected occupancy rate, nightly rate, cleaning fees, and management costs to instantly calculate your monthly cash flow, annual ROI, cash-on-cash return, and cap rate.

• Long-Term Rental Analysis: Evaluate your buy-and-hold investments with monthly rent, maintenance, and vacancy rate inputs. See how stable, predictable income compares to a vacation rental strategy.

The spreadsheet automatically provides a side-by-side comparison of both models, helping you decide which investment approach delivers stronger returns for your specific property.

✔ Built-In Mortgage Calculator

No need for separate tools — the mortgage calculator is integrated directly into the spreadsheet.

Just enter your:

• Purchase price

• Down payment percentage

• Interest rate

• Loan term

• Property taxes and insurance

And watch as your monthly mortgage payment, principal vs. interest breakdown, and net cash flow automatically update in real time.

✔ Instant Key Metrics You’ll Get

Your Investment Property Calculator automatically calculates all the numbers that matter most to real estate investors:

• ROI (Return on Investment) – Measures the total profit compared to your investment cost.
  
  Equation: ROI = (Annual Net Profit ÷ Total Investment) × 100

• Cap Rate (Capitalization Rate) – Evaluates a property’s profitability based on income vs. purchase price.
  
  Equation: Cap Rate = (Net Operating Income ÷ Purchase Price) × 100

• NOI (Net Operating Income) – Calculates total income after operating expenses (excluding mortgage).
  
  Equation: NOI = Gross Income – Operating Expenses

• Cash-on-Cash Return – Measures actual cash returns on your cash invested.
  
  Equation: Cash-on-Cash = (Annual Pre-Tax Cash Flow ÷ Cash Invested) × 100

• 1% Rule – Quickly determine if the property’s rent meets the minimum return threshold.
  
  Equation: Monthly Rent ÷ Purchase Price ≥ 1%

• 10% Rule for Short-Term Rentals – Common rule of thumb used by STR investors to ensure profitability.

Every formula is already embedded — you simply input your numbers and instantly see your property’s financial picture.
