If you’ve ever looked at a FIRE calculator and thought, “My net worth looks fine - why does FI still feel far away?” you’re not confused. You’re noticing something real: net worth measures wealth on paper; FI progress measures what can sustainably fund your life under the assumptions you choose (spending, withdrawal rate, returns, timeline).
That difference matters most when a large share of your wealth lives in a home, a business, or other assets you don’t plan to spend like a portfolio.
What net worth shows
Net worth is your balance sheet in one line: what you own, minus what you owe. It’s useful for tracking overall wealth, comparing year over year, and understanding leverage. It can include your house, cars, collectibles, and every account - liquid or not.
For many households, housing is a big part of the “own” column. That’s legitimate wealth. It’s also different from money you’re treating as the engine for retirement withdrawals, because living in the home doesn’t automatically convert equity into spendable cash flow.
What FI progress shows
“FI progress” (or “FI percentage”) usually answers a narrower question: How close are my investable assets to the portfolio size I’d need to support my target spending?
In practice, that means things like brokerage accounts, cash you’d actually deploy, pensions or retirement balances you’re counting toward independence - not necessarily every dollar on your net worth statement. The exact definition is yours to align with your plan; the important part is being consistent about what you’re measuring.
On FI Runway, we keep that distinction visible so you’re not accidentally cheering a headline net worth number while your FI bar moves on a different track.
Why housing can make net worth look stronger than FI progress
Home equity can be a wonderful thing. It can also make net worth climb while FI progress lags - especially if your investable pile is still small relative to your FI target.
Imagine high home equity and a mortgage you’re paying down: net worth may look impressive because the asset is large and debt is shrinking. Meanwhile, FI progress might still depend heavily on how fast you’re building the portfolio you’ll actually draw from. Same life, two different lenses - and both are useful if you know which is which.

What usually counts toward FI progress
Everyone’s plan differs, but a sensible default is to treat FI progress as driven by assets you’re willing to model as part of your independence stack - typically investable accounts and cash you’d use, plus retirement balances you’re counting on - measured against a target derived from spending and withdrawal rate.
What doesn’t automatically move the FI bar
Home value and debt still belong in your picture: they affect net worth, monthly cash flow, and long-term projections. They just don’t always belong in the same numerator as “progress to FI” unless you’ve made a deliberate choice about how you’ll use that equity.
That’s not a moral statement about homeownership. It’s a modeling choice that prevents a common mistake: confusing illiquid or non-withdrawal wealth with portfolio readiness.
Why this matters when planning for financial independence
When net worth and FI progress are blurred, people tend to optimize for the wrong scoreboard - chasing a headline number, or feeling behind when the headline is fine. Clear separation helps you ask better questions: Am I building investable assets fast enough? Is my spending target realistic? Does my withdrawal assumption match how I’ll actually live?
It also makes conversations with partners or advisors sharper: you can point to which metric moved and why, instead of debating a single ambiguous total.
Our How it works page walks through how FI Runway structures inputs, projections, and what-if checks around that idea - without turning your life into a spreadsheet.
