FIRE stands for Financial Independence, Retire Early. The idea: build enough wealth to live on, and working becomes a choice rather than an obligation.
The best-known rule of thumb from the movement is that you need twenty-five times your annual spending. At €40,000 a year, that's a million euros.
That rule comes from the United States: a country without a state pension, without mandatory occupational pensions, and with healthcare costs you carry yourself until sixty-five. Anyone applying it directly in the Netherlands is signing up for years of unnecessary work.
What does FIRE actually mean?
The two halves of the acronym aren't equally important.
Financial Independence means your wealth can cover your spending without you having to work for it. That's the goal.
Retire Early is what you do with it afterwards, and plenty of people in the movement don't stop working at all. They work less, change fields, start something of their own, or carry on doing exactly what they did: just without having to.
The useful half is the first. Financial independence is a number you can calculate and work towards. Retiring early is a decision you only have to make afterwards.
Where the movement comes from
The thinking predates the term. Your Money or Your Life, published in 1992, laid the foundation: work out how many hours of your life a purchase costs, and most purchases look different.
The arithmetic arrived in 1998 with the Trinity study, in which three American professors examined what percentage you can withdraw annually from a portfolio without exhausting it over thirty years. That produced the 4% rule, and 4% inverted is exactly that factor of twenty-five.
Around 2010 it acquired a name and an audience, largely through American blogs. The Dutch version followed later, with a community that never quite adjusted the arithmetic to the country it's applied in.
The American formula
The standard calculation is short:
Target wealth = annual spending × 25
Behind that multiplication sits an assumption that's rarely stated: that your portfolio must cover your spending forever. Twenty-five times your spending at a 4% withdrawal rate is an amount designed to last indefinitely.
For a fifty-year-old American that's reasonable. There's no meaningful state pension, no accumulated employer pension pot, and health insurance comes out of your own pocket until Medicare begins at sixty-five.
For a fifty-year-old in the Netherlands, that assumption is simply wrong.
Why the formula doesn't apply here
There are three differences, and together they open a large gap.
You receive a state pension
From state pension age, currently 67 and rising with life expectancy, you receive a government payment regardless of what you've saved. That's a guaranteed floor under your spending which an American doesn't have in this calculation.
What you receive depends on whether you live alone or with a partner, and on how many years you were insured in the Netherlands. Each year abroad costs you 2% of the accrual. Your current amount and your personal date are with the SVB.
You've probably built up an occupational pension
If you're employed, chances are you're accruing pension through your employer. That money is there even if you stop working at fifty: accrual stops, but what's accumulated stays and becomes available at your pension date.
You probably don't know that figure offhand. It's on mijnpensioenoverzicht.nl, where all your accrued rights sit together.
You don't need the amount forever
This is the pivot. Because state and occupational pensions eventually switch on, your own wealth doesn't have to cover your full spending for the rest of your life. It has to do two things:
- Cover your full spending from your stop date until state pension age
- Fill the gap that remains after that date
The first is a bridge with an end date, not a perpetual provision. And bridging is substantially cheaper than providing forever.
The Dutch formula: the pension bridge
The calculation splits into two phases.
Phase 1: the bridge. From your stop date to state pension age you cover everything yourself. What you need is the present value of your annual spending across those years, accounting for the return on what's still invested.
Phase 2: after that. From state pension age, both pensions arrive. Whatever spending remains uncovered is your gap, and you need capital for it, but only from that date, so you can discount it back to today.
Worked through. Someone aged fifty who wants to stop, spends €40,000 a year, and calculates with a 4% real return. The bridge is seventeen years.
Phase 1: seventeen years of €40,000 a year costs €486,627 today.
Phase 2: say €18,000 of state pension and €12,000 of occupational pension will arrive, €30,000 together. The gap is then €10,000 a year. That requires €250,000 at age 67. Discounted back seventeen years at 4%, that's €128,343 today.
Together: €614,970.
Against the American figure of €1,000,000.
The pension amounts here are examples. Check your own figures with the SVB and on mijnpensioenoverzicht.nl, that's where the largest differences between people sit.
What that saves
The same person, the same spending, three situations:
| Situation | Target wealth | Difference vs 25× |
|---|---|---|
| American rule of thumb | €1,000,000 | - |
| Single, no occupational pension | €768,982 | €231,018 less (23%) |
| Single, with pension | €614,970 | €385,030 less (39%) |
| Couple, with pension | €525,130 | €474,870 less (47%) |
Even in the worst case, single, never accrued a pension, state pension only, it saves €231,000. With average pension accrual it saves nearly four hundred thousand.
As a check on the method: set both state and occupational pension to zero and the calculation returns exactly €1,000,000. The American rule isn't a different sum: it's the same sum for someone with no state pension and no occupational pension.
What that saves in years
Euros say less than time. Take someone with €150,000 who sets aside €25,000 a year at a 4% real return:
| Target | Years remaining |
|---|---|
| €1,000,000 (American) | 21.9 |
| €768,982 (single, no pension) | 17.5 |
| €614,970 (single, with pension) | 14.2 |
| €525,130 (couple, with pension) | 12.0 |
Nearly eight years between the rule of thumb and the realistic calculation. That isn't a detail in your planning, that's a different life.
The four flavours of FIRE
Variants exist within the movement, differing mainly in how completely you stop.
Lean FIRE: your target is low because your spending is low. Reachable sooner, less margin if something goes wrong.
Fat FIRE: your target is high because you want to keep your current lifestyle. Takes longer, more comfortable.
Coast FIRE: you've accumulated enough to reach your pension date without further contributions. You still need to work for current spending, but no longer for your future. For many people this is the first achievable milestone.
Barista FIRE: your wealth covers part of your spending, and you earn the rest doing work you want to do rather than have to.
In the Netherlands, Coast FIRE is particularly relevant precisely because of the pension bridge: part of your old age is already arranged before you begin. Each of these variants gets its own article in this series.
What the bridge approach doesn't solve
Three things don't get easier, and it's more honest to name them than to leave them out.
The order of your returns becomes more dangerous. While you're accumulating, it barely matters whether a bad year falls early or late. Once you're withdrawing, it matters a great deal. A sharp fall in the first years of your bridge means selling shares at the worst moment, and portfolios recover poorly from that. The bridge phase is precisely when you're most vulnerable.
You can't reach your pension pot. It becomes available at your pension date, which under most schemes isn't far ahead of state pension age. Early drawdown is sometimes possible, but at a permanently lower payment. Your pension pot lowers your target; it doesn't help you across the bridge.
The state pension is a political promise, not a contract. The age has shifted over recent decades and is tied to life expectancy. Anyone planning at thirty around a state pension at 67 is planning around a figure that can still move. The further off your stop date, the more margin you should build in here.
And one thing outside this article that belongs in your calculation: wealth above an exemption is taxed annually. That reduces your net return and should be reflected in your real percentage rather than forgotten.
Where do you start?
Three steps, in this order.
Know what you spend. This is the hardest and the most important. Your target is a multiple of your spending, so an estimate that's 20% out puts your target hundreds of thousands out. Use what you actually spent over the past twelve months, not what you think you spend.
Know what you have. Not just your investment account. Also your savings, your crypto, your home equity and your accrued pension: the last two together are larger than the rest for most Dutch households. Without that total, any calculation is a guess.
Calculate your bridge. Stop date, state pension date, the difference in years, and what arrives after that date. That produces one number and one date.
How Gylder fits in
The second step is usually where this falls apart. Almost nobody can state their total wealth from memory, because it's spread across a bank, a broker, an exchange and a house.
Gylder brings that together into one continuously updated figure: accounts, investments, crypto, precious metals, your property with the mortgage underneath it. That figure is the starting value of any FIRE calculation.
You can also set a target amount with a target date: precisely the two outputs of the bridge calculation. Gylder tracks your progress against it and projects from your own measured growth rather than an assumed percentage.
One thing it can't do yet: include your accrued employer pension as an item. That data sits with mijnpensioenoverzicht.nl and isn't connectable. For the bridge calculation that's no obstacle: your pension belongs there as a future income stream, not as wealth you currently hold. An annuity or pension investment account at a broker connects normally, because it's a securities account like any other.
What this doesn't tell you
Every figure in this article rests on assumptions that won't play out exactly over thirty years.
The 4% real return is a historical average, not a promise. State pension amounts move with policy and indexation. Your spending at seventy won't resemble your spending now: commuting disappears, healthcare costs arrive. And the largest unknown is your own life, which rarely conforms to a projection.
What the calculation does do: it gives you a target considerably closer to reality than twenty-five times your spending. And it makes the levers visible, your spending, your stop date, your savings rate, rather than handing you one number from above.
Frequently asked questions
How much do I need to stop working? It depends on your spending, your stopping age and what arrives after your state pension date. For someone stopping at fifty with €40,000 of annual spending and average pension accrual, it's around €615,000: not the million the rule of thumb suggests.
Does the 4% rule work in the Netherlands? As a withdrawal rate it's usable, with caveats that deserve their own article. As a target calculation, twenty-five times your spending, it overstates, because it ignores state and occupational pensions.
Does my house count towards my FIRE number? Only if you intend to realise it. Keep living there and the equity produces no income. What does help is that a repaid mortgage lowers your monthly costs, and that genuinely lowers your target.
Can I access my pension early? Many schemes allow it from a certain age, but at a permanently lower payment. For the bridge years it's usually not a solution.
Is FIRE realistic on an average salary? The arithmetic works at any income; what differs is the timeline. Your savings rate drives that timeline more than your return: at 20% set aside you're looking at over thirty years, at 40% at just over twenty.
