Does Home Equity Count Toward Your FIRE Number?

You have $600,000 of equity in your house. Your FIRE number is $2 million. Are you $600,000 closer, or exactly where you were?

Both answers are defensible, which is the problem. Left unresolved, it produces a plan that is either badly over-optimistic or needlessly pessimistic — and the difference between those is measured in years of working.

The test: does it fund withdrawals?

A FIRE number is not a wealth target. It is a target for assets that can produce spendable cash indefinitely. That is a narrower thing than net worth.

Run the test on your house: over the next twelve months, how many dollars of your grocery bill, insurance premiums, and travel will your home equity pay for?

Zero. Unless you sell it, borrow against it, or rent part of it out, equity in a primary residence is wealth that produces no income. It is often called dead equity — not a judgment on the decision to own, just a description of its cash-flow behaviour.

Worse, a house is cash-flow negative. Property taxes, insurance, and maintenance all leave your account every year. So an owned home simultaneously inflates your net worth and increases the spending your portfolio has to fund.

The three honest treatments

The correct treatment depends entirely on what you actually intend to do.

1. Living there indefinitely: count zero

If you plan to stay, your equity funds nothing. Exclude it.

The compensation is on the spending side: owning outright means no rent and no mortgage payment, which makes your annual spending — and therefore your FIRE number — dramatically lower than a renter's. A paid-off house does not add to your assets in this model. It subtracts from your target, by removing housing costs from your budget. That is a large benefit, correctly counted once instead of twice.

The trap is double-counting: adding $600,000 of equity to your assets and using a low, no-rent spending figure. That claims the same benefit twice.

Do remember to keep the carrying costs in your spending figure. Property tax, insurance, and a maintenance allowance — a common rule of thumb is 1% of home value annually — are real retirement expenses. On a $900,000 house that can run $18,000 a year, which at a 4% withdrawal rate requires $450,000 of portfolio to sustain.

2. Downsizing on a specific date: count the difference, after costs

If you intend to sell a $900,000 house and buy a $500,000 one, the FIRE-ready portion is not $900,000 and not the full equity. It is the difference, net of the cost of moving.

Selling costs are substantial and consistently underestimated. Agent commission, transfer taxes, and repairs commonly total 6-10% of sale price. Then add moving costs and the near-certainty that the cheaper house needs something.

This is why a liquidation haircut belongs in the model. In the Can I FIRE Yet? Calculator, redeployed real-estate equity is multiplied by 0.9 — a flat 10% haircut — before it counts. On $400,000 of released equity that is $360,000 of FIRE-ready assets. Conservative, but closer than $400,000.

A caution on timing: "we will downsize eventually" is not a plan you can put in a spreadsheet. If the move is genuinely ten years out, the equity is not funding your first ten years of retirement — which are precisely the years that decide whether an early retirement works.

3. Renting it out: count the income, not the equity

If the property becomes a rental, it stops being dead equity and starts being an income asset. Now the correct move is the one from the passive-income playbook: subtract the net cash flow from your spending rather than adding the equity to your assets.

portfolio_funded_spend = annual_spending − net_rental_cash_flow
required = portfolio_funded_spend / withdrawal_rate

Net is doing real work in that formula. Net rental cash flow is rent minus mortgage, taxes, insurance, management, maintenance, and a vacancy allowance. Gross rent is not income; it is revenue.

The tradeoff nobody frames explicitly

Here is where landlords get stuck, and it is worth stating as an actual tradeoff rather than a preference.

You own a rental with $500,000 of equity throwing off $20,000 a year of net cash flow. Two options:

Keep it. Assets unchanged. Spending target drops by $20,000. Against $80,000 of spending at a 4% rate, you need $60,000 / 0.04 = $1,500,000 in the portfolio.

Sell and redeploy. Assets rise by $450,000 after the haircut. The $20,000 of income disappears, so the target returns to $80,000 / 0.04 = $2,000,000 — but you now have $450,000 more toward it.

Which wins depends on the rental's yield relative to your withdrawal rate. That $20,000 on $500,000 of equity is a 4% yield — almost exactly a 4% withdrawal rate, so the two options are close to a wash on the arithmetic, and the decision comes down to things arithmetic does not capture: concentration risk, whether you want to be a landlord in retirement, transaction costs, and capital-gains tax on the sale.

If the same equity threw off $35,000 (7%), keeping it is clearly stronger. At $10,000 (2%), the property is underperforming a portfolio and the equity is better deployed elsewhere.

This is exactly why the calculator lets you set redeployment to 0%, 50%, or 100% and shows the effect on the gap as a swing factor — and why redeploying equity also removes the matching share of rental cash flow. Move the two together, or the model lies to you.

What about a HELOC or a reverse mortgage?

Both convert equity to cash without selling, and neither is a clean substitute for FIRE-ready assets.

A HELOC is debt. Borrowing to fund living expenses means paying interest on your own consumption, and lenders can reduce or freeze lines exactly when markets are stressed — which is when you would want it. It is a legitimate emergency backstop. It is not a retirement income plan.

A reverse mortgage genuinely converts equity to income, but is generally restricted to 62+, carries substantial fees, and reduces what passes to heirs. If you are planning to retire at 45, it does nothing for the two decades that matter most.

The practical answer

For most people the honest treatment is:

Exclude primary-residence equity from FIRE-ready assets by default.
Keep property taxes, insurance, and maintenance in your spending figure.
If you have a specific downsizing plan with a date, count the difference less 10%.
If a property will produce income, subtract that income from spending instead of adding equity to assets.
Sanity-check the answer both ways. If your plan only works when home equity counts, you have a plan that depends on selling your house.

That last point is the one worth sitting with. There is nothing wrong with a plan that involves selling — plenty of good plans do. There is a great deal wrong with a plan that requires selling and has never said so out loud.

The Can I FIRE Yet? Calculator shows the exclude / 50% / 100% scenarios side by side, so you can see how much of your progress depends on the house. For a two-person household with different retirement dates, the Couples FI Planner handles the timing separately. And if selling means realising a large gain, the Roth Conversion & Capital Gains Headroom Planner shows what that does to your income thresholds in the year you sell.
