Saving 10% of your income has long been considered a solid benchmark when planning for retirement. But is it really enough to retire comfortably?
For years, financial experts have urged employees to save 10% of their income and put it toward retirement. While 10% may be a simple and straightforward goal to pursue, in reality it may not be enough to fund a comfortable retirement.
While it’s impossible to predict exactly how much you’ll need during retirement, there are some simple rules of thumb that could help you get a ballpark estimate:
- The rule of 25: For every dollar you need now to maintain your lifestyle, you’ll need 25 times that amount saved by retirement, according to this guideline. For example, if your yearly expenses amount to about $50,000 now and you want to maintain that same lifestyle during retirement, you’ll need to have roughly $1,250,000 saved by the time you retire.
- The 4% rule: Another general rule of thumb is that you should withdraw about 4% of your total retirement savings during the first year of retirement. After that, you withdraw the same amount adjusted for inflation. So if you have $1 million saved, you’ll withdraw $40,000 the first year. Assuming an inflation rate of 3%, you’ll then withdraw $41,200 (that’s $40,000 x 0.03) the next year, and so on. In theory, following this rule will allow your retirement savings to last at least 30 years.
Now let’s see how saving 10% of your salary each year holds up to these guidelines once you reach retirement age.
What 10% really looks like
The average income for Americans under the age of 65 is $46,409 per year. For those aged 25 to 34, it’s just under $40,000 per year, and for 55- to 64-year-olds it’s just under $50,000 per year.
So let’s say, for example, you started saving 10% of your income at age 25 while earning a yearly salary of $40,000 and continued saving 10% per year until age 65, at which point you’re earning $50,000 per year. Assuming a yearly rate of return of 7% on your investments, here’s what your nest egg would look like by the time you retire at age 65:
So if you save 10% of your income each year and earn a 7% rate of return each year, you’ll end up with about $912,500 by age 65. Now let’s look at the rule of 25 and the 4% rule to see how that nest egg stacks up.
The rule of 25 considers your yearly living expenses (not your salary), so for this example, let’s say you need about $40,000 per year to cover all of your expenses. According to the rule of 25, that means you’ll need a nest egg of about $1 million to maintain your standard of living during retirement. In this example, you’d be a bit shy of that target, but not drastically so.
Now let’s see how your $912,500 in savings would hold up to the 4% rule. You’d withdraw roughly $36,500 your first year. Assuming a 3% inflation rate, that number becomes $37,595 your second year, $38,723 your third year, and so on. Assuming your yearly living expenses amount to $40,000 per year, you may have to tighten your budget somewhat.
These calculations also assume you’ve started saving for retirement at age 25 and have consistently earned a higher salary while continuing to contribute 10% of your income every year. (In other words, it’s essentially the best-case scenario.) If you started saving later in life, took a pay cut at some point in your career (or were unemployed for a significant period of time), or had to contribute less than 10% of your pay for a few years, you’ll have to save even more to catch up.
