How Much Money Do I Need to Retire?
The 25x Rule of Thumb

For the vast majority of us who don’t have a defined benefit pension plan, one of the most important questions of your financial life is “how much money do I need to retire?”. This is a very important question to get right. If you save too little for retirement, you’ll need to work for longer than you planned, and your retirement will be cut short or you will need to spend a lot less in retirement (there goes that trip to Europe). On the other hand, if you overestimate how much you need to retire you will be “over-saving” during your working life which forces you to cut down on consumption during your working life (there goes that trip to Europe) and may mean you work for years longer than you need to.
It is critical to at least be in the ballpark when answering that important question “how much I need to retire?” Fortunately, you don’t have to be a finance guru to get an idea of how much you’ll need, enter the 25x rule.
The 25x Rule of Thumb
The 25x rule is quite simple, it states that you need to save 25 times your annual expenses to retire. Note that is not 25 times your annual income, but 25 times your annual spending. The key piece of information you will need to figure out is how much do you expect to spend in retirement? Keeping in mind some major expenditures such as your mortgage and saving for retirement could be gone, and that you may want to greatly increase your spending for things such as travel.
To better understand let’s look at an example. If I want to retire today, and I know my expenses moving forward will be about $30,000 per year, the 25x rule tells me that I will need approximately $750,000 ($30k x 25) to fund my retirement. The more frugal you are, the less you would need to have saved up for retirement if you want the “gold plated” retirement you best be ready to stash away some serious savings.
Assumptions & Limitations of the 25x Rule
Like with any rule of thumb, the 25x rule uses some assumptions and has limitations best we discuss them. The 25x rule has the following assumptions”
The 25x rule assumes you have no other sources of retirement income
This includes income from a defined benefit pension, social security, government-sponsored pensions or rental income. So if you have any of these things to fund part of your retirement your personal retirement savings could be smaller than 25 times your spending.
In my previous example I mentioned I would have $30,000 in annual expenses during retirement and that according to the 25x rule, I would need $750,000 to fund that retirement. What if I have a defined benefit pension plan that will pay me $16,000 per year? Since I have the first $16,000 of my retirement savings covered by my pension, I would only need to save around $350,000 (the remaining $14k times 25) to fund my retirement, a much more manageable amount.
The 25x rule also makes some assumptions that your retirement savings will generate at least a 4% annual rate of return, above inflation. If during your retirement the returns in your retirement savings are lower than you expected, or inflation is higher than you expected, the 25x rule may not be enough to fully fund your retirement. This is by no means a guarantee, that is why they call it a “Rule of thumb”.
While the 25x rule is not an exact formula, it is a useful indicator to get you started and give you a ballpark figure of how much you might need to save to fully fund the retirement you want.
