House Hacker’s FIRE Projector

Most FIRE calculators know exactly one asset: a stock portfolio. This one also understands rental property — monthly cash flow that grows with rents, a mortgage that eventually pays off, and the housing cost a house hack removes from your budget. It runs your numbers both ways, side by side: investing only, versus investing plus a house hack. Free, no account, and your scenarios save right in your browser.

You and your money

Your age

Annual spending you want covered in retirement ($)

Invested savings today ($)

Monthly amount you invest ($)

Expected return, after inflation (%)

Withdrawal rate (%)

The house hack (scenario B)

Monthly rental cash flow while you live there ($)

Housing cost the hack saves you, invested instead ($/mo)

Annual rent growth (%)

Years until the mortgage is paid off

Extra monthly cash flow once paid off ($)

Tip: get the cash-flow and effective-housing-cost figures from the House Hack Calculator — they drop straight in here.

When does work become optional

A — Investing only

—

B — Investing + house hack

—

Planning model, not financial advice. Uses real (inflation-adjusted) returns, so all dollars are today’s dollars. Rental income reduces the portfolio you need: at a 4% withdrawal rate, every $100/mo of durable rental cash flow replaces $30,000 of portfolio.

The two inputs that matter most come from the property itself: run a candidate through the House Hack Calculator for the cash flow and effective housing cost, then sanity-check the long hold with the Long-Term Projection. For the strategy behind the shortcut, read house hacking your way to FIRE.
