Retire Early With Kids: A 5-Step Guide To The Fastest Way

We’ve been on our journey towards FIRE (Financial Independence Retire Early) for over five years and can confidently say this: retiring early with kids is possible. Especially if you choose a simpler, more flexible path to financial independence that’s becoming increasingly popular in the FIRE community — yet it is still widely misunderstood. This way is also the fastest track to an early-retired lifestyle.

In this post, I share our family’s honest journey from chasing traditional early retirement, hitting our limits, and finally shifting toward semi-retirement. Today, we’re close to semi-retiring early with kids and enjoying real work-life balance (or rather work-kids balance) far sooner than we ever thought possible. It’s been a bumpy road and quite a rollercoaster of emotions for us, that I will share very honestly so you can avoid the same pitfalls we’ve been through.

This guide breaks down five simple steps to retire early with kids. Most people follow them in the wrong order — and that’s what makes FIRE feel hard and overwhelming. Swap two key steps, and early retirement becomes far more realistic, sustainable, and family-friendly — without that rollercoaster. Let’s start.

Step 1: Define What “Retire Early” Means for Your Family

When we started our FIRE journey, what’s now Step 1 was actually our Step 5. Years later, we realized it should have been the very first step all along.

Choose Your FIRE Path: Traditional vs Semi FIRE

What it means

Choosing your FIRE path means deciding whether you want to stop working entirely or keep some form of income while gaining more time freedom.

Take the time and study the different FIRE paths before you choose your personal FIRE path — the most prominent ones are the following:

• Traditional FIRE (stop working)
• Barista FIRE (part-time work + withdrawals / passive income)
• Coast FIRE (part-time work + no withdrawals yet)
• Flamingo FIRE (hybrid)

Why it matters for parents

For families with kids, this decision affects cash flow stability, healthcare, daily routines, and how much time you actually get with your children — before reaching FIRE and afterwards.

Common mistake

A common mistake is aiming for traditional FIRE by default — as we did — without realizing that semi-retirement paths like Barista or Flamingo FIRE may fit your family life much better.

What to do next

Compare traditional FIRE with semi-retirement options like Barista FIRE, Coast FIRE, and Flamingo FIRE to see which FIRE path fits your family best.

The Questions to Ask Before You Decide to Retire Early with Kids

Need some food for thoughts? Answer the following questions honestly to get clarity of your true life goals, retirement goals and find the retirement plan that is right for where you‘re at in your life right now.

1. What feelings arise when you think about the discomfort you‘re facing today in your work life?
2. Why is FIRE the answer and not just changing jobs?
3. Why does the idea of financial independence speak to you? What should that bring into your life?
4. What role should work play in your retirement life?
5. Do you want to get paid for the work you will continue doing?

Our Story: From Chasing Early Retirement to Seeking Semi-Retirement First

What does early retirement actually mean for you? How do you want your everyday life to look — and how do you want to get there?

Marc and I realized along the way that we wanted the time freedom financial independence offers much sooner — while our kids are still young — not a decade from now. Waiting and working like a maniac for a distant FIRE date simply didn’t match the family life we wanted.

We saw two obvious options: make drastic changes like geoarbitrage to save and invest even more, or earn significantly more money by working even longer hours — ideally both of us. But neither path felt desirable or sustainable for us as a family.

At the same time, we realized we don’t actually want to stop working entirely. Work gives us purpose, and we want it to remain part of our lives — just on our own terms.

What we truly want is full time flexibility, not full retirement.

We struggled for a long time because we hadn’t clearly defined what “retire early” meant for our family or how we wanted our daily life to look once we reached it. That missing clarity made everything else feel harder than it needed to be.

Step 2: Create a Strategic FIRE Plan (and Use the Right Tools)

Once you know what FIRE means to you and which FIRE path you want to go with your family, it’s time for financial planning, which didn’t exist for most of my adult life. More about my story later. But first, let’s look at how you do it.

Creating a Strategic FIRE Plan

What it means

Creating a strategic FIRE plan means turning your goals, income, expenses, and investments into a clear roadmap — not guesses or rough rules of thumb.

Why it matters for parents

Families deal with changing expenses, uneven income, and limited time. A clear plan reduces stress and helps you adapt without constantly second-guessing decisions.

Common mistake

Focusing only on a single FIRE number or investment strategy without seeing how everything works together — which often leads to unnecessary pressure or unrealistic goals.

What to do next

Use our free FIRE calculator and the Semi Retirement Calculators we offer to model different paths, including Barista FIRE, Coast FIRE, and Flamingo FIRE, and see which strategy fits your family best.

Tools to Create Your Financial Plan for FIRE

We struggled a lot at the beginning of our FIRE journey as we lacked having the right resources on hand. Despite tracking our expenses and budgeting our money for years, using online tools like Ynab, we had no clue how to create a financial plan for FIRE.

As we couldn’t find the right resources, we created our owns. We never intended to share those. But today, you can find the first ones in our Freebies Library (to get you started).

If you’re new to tracking your expenses and budgeting your money, I like to motivate you: It’s easier than you may think. There are a ton of free resources to help you out like The Budget Mom I can personally recommend as well as:

1. Ynab: an online app to track and review what you spend (like we do for > 10 years)

Our Story: From Financial Mess to Money Boss

For years, we did what most people do: saved a little, invested even less, and paid off debt — without a real plan. We tracked expenses and budgeted, but apparently for the wrong things. Our money just wasn’t working toward a clear goal.

That changed in 2020. Our first baby had just been born, we had bought a house, and the pandemic hit. Despite earning above-average incomes, we realized that losing a job could force us to sell our home. How could that happen? That wake-up call showed us something was fundamentally wrong with our financial setup.

At the same time, becoming parents made us want more time freedom as a family — not less work, but flexible work on our own terms. Then I discovered the concept of FIRE: investing intentionally so your portfolio can one day support your life. We then could enjoy decades of retirement instead of only 10+ years (if we would retire at traditional retirement age of almost 70 years). This was it! But could the dream of early retirement work out for us (as we were already in our mid 30s)?

Marc ran the numbers, and quickly found the simple math behind early retirement. Suddenly it was clear. Financial independence and early retirement with kids weren’t unrealistic — they were achievable through strategic planning, intentional frugal living, budgeting, and long-term investing. That realization changed everything.

Step 3: Calculate Your FIRE Number with Kids in Mind

What it means

Your FIRE number is the amount you need invested to support your lifestyle from your portfolio. Or in other words: so that the passive income it generates can pay for your bills. When you have kids, this number must reflect longer timelines, changing expenses, and forecast your future expenses which can be hard to predict.

Why it matters for parents

Children increase both current and future costs, from childcare to education and daily living. Planning for these realities upfront helps avoid unpleasant surprises later.

Common mistake

Calculating a FIRE number based only on today’s expenses and assuming kids’ costs will stay flat — which can lead to underestimating how much flexibility you actually need.

What to do next

Use a FIRE calculator that allows you to add buffers for rising family expenses and test different withdrawal strategies to see how they affect your timeline. Our free FIRE calculator offers a section called “Recurring Income or Expenses” which allows you to plan additional costs or income sources in the future from a start and end date.

The 4% Rule (and What’s Behind Your FIRE Number)

The 4% rule is a guideline for retirement withdrawals. It means you withdraw 4% of your investment portfolio per year to fund your retirement — which is why it’s also called the 4% withdrawal rate.

Why 4%? Historical data suggests that withdrawing 4% annually makes it very unlikely to run out of money over a retirement period of up to 30 years, assuming a US-focused stock portfolio. For longer retirements (30+ years) or more globally diversified portfolios, many people use a lower withdrawal rate of 3–3.5% to add extra safety.

Your chosen withdrawal rate directly determines your FIRE number. At 4%, you need roughly 25× your annual living expenses invested. For example, if you spend 40,000 per year, your FIRE number would be about 1,000,000. Not sure where that comes from? Let’s break it down step by step below.

If you want a deeper dive, check out one of the most well-known articles in the FIRE community: The 4% Rule: The Easy Answer to “How Much Do I Need for Retirement?”.

If you want a deeper breakdown by age and retirement length, I’ve written a detailed article: What Is a Safe Withdrawal Rate in Retirement? 4% Rule by Age.

Your FIRE Number Explained

Your FIRE number is the amount you need invested so your portfolio can cover your living expenses in retirement.

If you plan for up to 30 years of retirement, a common approach is the 4% rule (and withdrawal rate). In that case, you multiply your annual spending by 25. That result is your FIRE number.

For longer retirements (30+ years), many people use a more conservative 3.5% withdrawal rate. In practice, that means multiplying your annual spending by 29 to get your FIRE number.

Example:
If your expected annual spending in retirement is 30,000 (assuming you’re debt-free and healthcare is covered):

• 30,000 × 25 = 750,000
  → With a 4% withdrawal rate, you could withdraw 30,000 per year for about 30 years.
• 30,000 × 29 = 870,000
  → With a 3.5% withdrawal rate, you could withdraw 30,000 per year for 35–40 years.

This is why choosing the right withdrawal rate — and understanding your retirement timeline — is so important when calculating your FIRE number.

Accounting for Rising Costs as Kids Get Older

Here’s a checklist that parents can copy to account for rising kids-related expenses:

• childcare / school fees (ours doubled in 2 years just due to inflation)
• activities + hobbies
• food growth phase
• vacations / travel
• medical / orthodontics
• school trips
• “surprise” category (birthdays, class funds, etc.)

How can you account for increasing kids-related expenses if planning to retire early with kids?

Add 300-350/month buffer or round FIRE number up by 100,000. Those 100,000 more in your portfolio equates to a buffer of approximately €333 per month (according to the 4 % rule).

A Simple Family Example (How to Plan for Kids-Related Expenses)

Imagine a family of five with monthly expenses of 4,000. Adding a conservative buffer for growing kids brings this to around 4,300. Instead of aiming for full retirement immediately, they plan semi-retirement by covering part of their expenses with flexible work and the rest from investments — reducing pressure while gaining more time together as a family.

Our Story: How to Account for Rising Kids-Related Expenses

Even when you live a frugal lifestyle as a family — as we happily do — costs tend to rise as kids get older. I share more about mindful, family-friendly frugal living in the post How I Spend My Money On What Matters Most & Skip The Rest.

Some child-related expenses are hard to predict, but they still matter when planning to retire early with kids. School choices, activities, and the need for flexibility can quietly increase your long-term costs.

One thing we personally underestimated was school planning. We recently decided to send our oldest daughter to a private school because she’s thriving in the attached Montessori preschool. That choice wasn’t part of our original FIRE number — and it was a clear reminder of why building buffers into your plan is so important (which we didn’t).

Step 4: Build Your Savings Rate as a Family

Once you know your FIRE number and developed a financial plan for how to retire early with kids, you need to make those savings and investments happen.

What it means
Your savings rate is the portion of income you keep and invest instead of spending. It’s the single biggest driver of how fast you reach any form of FIRE.

Why it matters for parents
Families often have less flexibility with time and energy. A strong savings rate lets you make progress toward FIRE without relying on extreme work hours or constant side hustles.

Common mistake
Trying to optimize everything at once or focusing only on earning more instead of first controlling fixed family expenses.

What to do next
Review your largest expense categories and adjust them intentionally, then use a simple family budget or Bare Bones Budget Calculator to lock in a sustainable savings rate.

What Drives Your Family’s Savings Rate

Saving more money comes easy to some of us who are used to living frugally. But, everyone can learn it and will profit from intentional money choices. How about you? Are you a frugal person by nature for whatever reason? For me personally, this was my daily reality a long time ago. But things have changed and I slipped into (excessive) consumerism.

Our Story: Achieving a 50-60 % Savings Rate

Marc and I became very intentional about saving more so we could invest more. Within about a year, we reached a 50% savings rate, and shortly after even 60% — roughly 30% invested in the stock market and 30% in real estate through our home, which we plan to rent out in the future eventually. We’re not extreme high earners, just a normal middle-class family.

Of course, maintaining a high savings rate isn’t always easy with kids, parental leave, or part-time work — which is common in Germany where we live. There were months when our savings rate dropped below 50%, or we paused investing entirely, especially during my longer parental leave. But those decisions were intentional.

Outside of that period, we’ve consistently maintained a savings rate of at least 50% — and even with another (shorter) parental leave ahead, that remains our goal.

Step 5: Invest for Passive Income (Without Overcomplicating It)

Once you start saving more money, where do you invest? Actually, it matters more that you just start investing (more) money — time matters more than the amount invested, especially when you just start. You know the saying “Time in the market always beats trying to time the market”? That is very true and we’ve wrote about that in the blog post How Should I Invest To Achieve Financial Freedom?.

What it means
Investing for passive income means building a portfolio that can eventually support your lifestyle through long-term growth and withdrawals — not short-term speculation.

Why it matters for parents
Passive income reduces pressure on earned income and creates stability during unpredictable family years, such as parental leave, reduced hours, or career changes.

Common mistake
Overcomplicating investing or delaying entirely because it feels intimidating — which often costs families valuable time in the market.

What to do next
Start with a simple, diversified investment strategy and focus on consistency, then revisit your asset allocation as your FIRE timeline becomes clearer.

Our Story: Investing for Passive Income

Once Marc and I committed to FIRE, we started investing in the stock market right away. We moved most of our savings from our bank account into a brokerage account and focused on low-cost ETFs and Index Funds. We automated our investments and consistently invested our money into our ETFs of choice. Over time, this simple and disciplined approach paid off.

Today, more than five years later, our stock market portfolio has grown to almost 150,000 — and it continues to grow, even during periods when our savings rate temporarily dips below 50%.

Vicki Robin is seen as one of the founders of the FIRE movement. Her book Your Money or Your Life: 9 Steps to Transforming Your Relationship with Money and Achieving Financial Independence takes a radically new view on “your hourly wage”. As she wrote, when you stop working for an income, you may be out of a 9-to-5 job but you will never be out of work. The book quickly became a New York Times and international bestseller featured in the “The Oprah Winfrey Show” and many others. I really enjoyed reading it.

This book that saved my FIRE journey and is one of my TOP 5 must-read books ever: The Simple Path to Wealth: Your road map to financial independence and a rich, free life. The author J L Collins shares his insights of the investment world and explains how to create a fortune in such a pleasant way that I have read the book in a couple of days. The core idea: investing in the stock market will make everyone richer than before, if doing it right and automate it.

Meet the Frugalwoods: Achieving Financial Independence Through Simple Living is a very personal story about a couple from the US (today a family of 4) who ditched a normal lifestyle and started simple living. They share first hand what it means to retire early with kids and how that can look like. This is one of my favorite FIRE books as it’s amazingly written and truly a pleasure to read.

A great further resource for everyones FIRE journey is the blog Our Rich Journey and their YouTube Channel focusing on retire EARLY as well as MoneyFlamingo who is all about Semi FIRE. Both offer resources like financial calculators, workbooks or even courses on how to retire early with kids.

Retire Early With Kids FAQ

What’s the biggest mistake when pursuing FIRE with kids?

Planning only for today’s expenses and not building a buffer for how costs change as kids grow.

What savings rate do families need for FIRE?

It depends on timeline and income, but many families target a higher-than-average savings rate and optimize fixed costs first.

Is Barista FIRE better than traditional FIRE for families?

Not necessarily better, but easier—because part-time income reduces Fire number, pressure on withdrawals and gives flexibility during those precious years kids are at home.
