Do you want to know how much money you need for (early) retirement? The rule of 25 is going to help you exactly how much you need to retire comfortably.
When you are striving for financial independence and early retirement, it is important to know how much money you need to retire. Preparing for retirement includes a definite savings plan and a retirement plan that everyone needs to follow. Retirement living will be so much easier because of this.
Having retirement goals in your savings plan will pay off handsomely when your expected retirement rears its head.
There are many things to consider when you’re planning for retirement and your retirement savings. To make things easier, let’s look at one widely used rule of thumb: the rule of 25. This is a retirement guide of sorts for those interested in having a good retirement.
Here’s what the rule of 25 is, how it works, and how you know how much you need to retire. Let’s take a journey to your financial future.
What Is FIRE?
FIRE stands for Financially Independence and Retire Early. Many people strive for financial independence, and some of them want to enjoy retirement early. Getting out ahead financially is mainly done by making extra money and living below your means. This is a sure-fire plan to meet your retirement plans.
Most people who want to reach financial independence do so by building passive income, saving money, and investing in mutual funds and the stock market.
While there are many reasons why people want to retire early, the most prominent reason for many is freedom. Do what they want to do, when they want to. For example, here’s what I plan to do when I am financially independent.
What Is The Rule Of 25?
The rule of 25 is a way to calculate how much money you need for (early) retirement. That amount is 25 times your expected expenses in retirement.
The multiply by 25 rule is a great way to know exactly how much money you need for early retirement or financial independence. This is your guideline on how to invest for retirement.
When you want to calculate your financial independence number, you must know approximately how much you want to spend in retirement. You won’t know exactly, but having a rough estimation will help when you’re working toward building that liquid net worth. This will help you in your income planning each month.

How Does The Rule Of 25 Work?
Let’s put the rule of 25 in practice. If you want to spend $3,000 per month in retirement, that is $36,000 per year. $36,000 multiplied by 25 is $900,000. That means you would need $900,000 to retire comfortably and spend $3,000 a month.

This number does not consider any other sources of income, like rental properties, side hustles, or social security.
While $900,000 is a lot of money, it’s often less than people expect. When I started my own financial independence journey, I expected to need millions to retire comfortably. Given that I can live on minimal expenses per month, I personally aim for $300,000.
The less money you can live on per month, the earlier you will be able to retire. Here are some tips to save money:
How do we know you can safely withdraw $3,000 per month from a $900,000 portfolio and not run out of money? That’s thanks to the 4% safe withdrawal rate!
Linking The Rule Of 25 To The 4% Rule
Another rule of thumb in personal finance is the 4% rule. The 4% rule states that if you withdraw 4% of your portfolio annually, you can live on that portfolio for an indefinite amount of time. The probability of your portfolio running out of money is there since compounding the amount makes it bigger as the years go by, but it’s low. Over 98% of portfolios haven’t run out of money after 30 years.
The rule of 25 determines how much money you need to save to retire. The 4% rule defines how much money you can take from your portfolio annually to prevent running out of money.
To prevent yourself from running out of money in retirement, your money must be invested. The average annual stock market return is 7%, which is corrected for inflation. If you withdraw 4% annually, there is enough money left in your portfolio to live off for a long time.
Does The Rule Of 25 Work?
While the rule of 25 is a great rule of thumb to aim at, it is not the end all be all. It mainly gives you a starting retirement number to work toward your retirement goals.
It’s crucial to know how much you need to retire. Implementing the rule of 25 can give you valuable insights into how you’ll allocate your money and a good chance of a successful retirement.

There are dozens of things that can change between the time you decide to retire and the time you start to plan for it. A couple of important things to ask yourself are:
- Where do I plan to live?
- What do I plan to do?
- What are my healthcare costs?
- Do I plan to have kids or pets?
Add all these plans up, and you will end up with a very rough estimation of what you will spend in retirement. Multiply that number by 25, and you get the amount that you need to retire.
The cost of retirement can vary significantly based on factors such as location, individual needs, health, and preferences. If you choose to retire at home, you’ll need to consider expenses like property taxes, utilities, upkeep, and modifications. Hiring in-home care might be necessary, adding to costs.
Conversely, assisted living facilities offer structured environments with services like meals, housekeeping, and assistance with daily tasks. Costs for assisted living depend on location, amenities, and care level. Generally, it’s pricier than staying home but includes convenient services.
When considering retirement options that align with your desire to travel, there are a few strategies to explore. One involves building substantial retirement savings through accounts like 401(k)s, IRAs, and other investments. This financial foundation can provide the funds needed to support your travel plans during retirement.
When it comes to pet ownership, you must consider the cost of grooming and feeding supplies. It’s a good idea to have an emergency fund set aside specifically for unexpected pet-related expenses, similar to an emergency fund for your own healthcare needs.
Improve Your Chance Of Successful Retirement
When you’re working toward 25 times your yearly expenses, be aware of the fact that you have two options:
- You never want to work again. In that case, it may be best to add a little safety margin to your financial freedom number.
- You are flexible. If you are flexible, saving 25x your annual expenses is great. You don’t work as long, but you know there’s an opportunity that you need to pick up some gigs at times. Here are some tips if you need money now.
Whether you’re flexible in retirement or you never want to work again, there are some things you can do to improve your chance of a successful retirement:
- Pay attention to the first 10 years. The early years of retirement are important. If things aren’t going well early on, it impacts the rest of your retirement. When you notice things aren’t going as planned, you can decide what decision fits you best at this moment.
- Extra income. If you get just a little bit of active income from work, this goes a long way in retirement. Every dollar that you get in extra income will help you down the line.
- Reduce your costs. If you notice that your retirement isn’t going as planned, you can decide to reduce your costs for a while. You can do that by cutting back on certain expenses or moving to a cheaper country. Correct allocation of your monthly income between your daily needs and retirement funds will help your plan to retire.
- Keep track of your finances. If your retirement plans are coming close, it is important to keep track of your finances. Know how your expenses have increased, what your buffer is, and how much you can spend per month in retirement. Budgeting has never hurt anyone. The amount of money you have earned, used, and saved is an important factor for the computation of your retirement calculator.
