How the FIRE Retirement Calculator with Real Estate Works
The FIRE (Financial Independence, Retire Early) movement traditionally relies on a portfolio withdrawal rate. Adding real estate transforms the equation: rental income reduces the amount you need to withdraw from your investments. This calculator computes your Adjusted FIRE Number as:
FIRE Number = (Annual Living Expenses − Net Rental Income) / Safe Withdrawal Rate
where Net Rental Income = Annual Rental Income − Annual Property Expenses.
Example: $60k expenses, $25k rent, $5k property expenses, 4% SWR → net rental $20k → needed portfolio = ($60k-$20k)/0.04 = $1,000,000.
We also project your current portfolio growth (adjusted for inflation) to the target age using FV = PV × (1 + r - inflation)^n and show the income contribution.
FIRE & real estate — why it matters
Real estate provides diversification, potential appreciation, and passive income that can lower the required nest egg. Our calculator uses your inputs to show both the reduced FIRE target and the blended passive income (4% from portfolio + net rent).
