What is the formula for rental property?

The formula used is: ROI = (Net Income + Appreciation) / Investment

Does this include property management fees?

Include property management costs (typically 8-12% of rent) in the monthly expenses field. For a hands-off investment, budget 10% of gross rent for management.

What about vacancy costs?

Vacancy is typically factored into monthly expenses. A conservative estimate budgets 5-8% of annual rent for vacancy costs. You can include this in your monthly expenses input.

How does leverage affect my ROI?

Leverage (using a mortgage) amplifies returns. With 20% down and 3% annual appreciation, your ROI on the down payment is much higher than if you paid cash — because you control the full property value with a fraction of the capital.

How Rental Property ROI Works

Your total return has two components: net cash flow from rent minus expenses, and property appreciation. The ROI divides your total return by your initial down payment. A positive cash flow property with strong appreciation can significantly accelerate your path to FIRE by providing both income and asset growth.
