There are lots of different ways to save for retirement, but none is more important to working Americans than a company's 401(k), 403(b), or 457 plan. While just about anyone can open up an IRA, funds in IRAs only accounted for 26.5% of all retirement savings in 2010, according to the Employee Benefits Research Institute.

That means that most Americans are relying on their workplace retirement program to help them fund their golden years. Figuring out where you stand among your peers can be a difficult task.

First, let's look at overall trends, then see what kind of differences exist when we break the average 401(k) balance out by one's age and salary.

Things are getting better, but there's still a long way to go
According to Vanguard's 2014 report, How America Saves (link opens a PDF), our 401(k) balances are healthier than they've ever been before. By the end of last year, the average (mean) 401(k) account registered with Vanguard clocked in at $101,650. That's up an astounding 80% since the end of 2008.

Even more impressive is the fact that -- for those who maintained their account between 2008 and 2013 -- the average balance was up 182%. The stock market helped juice gains, but folks are contributing more to their retirement plans than before.

But these numbers need to be put into perspective. Using the 4% rule for safe withdrawals, a balance of $101,650 will provide just over $4,000 per year in retirement -- a number far below what some might expect.

Even more disconcerting is the fact that the mean 401(k) is much higher than the median 401(k) -- thanks to high earning/saving outliers. If we are looking at median 401(k) balances, the number clocks in at $31,396.

But even this data is somewhat misleading. Simply looking at the "average" 401(k) balance doesn't help you find out where you stand -- there are huge differences when we account for age and salary.

Average 401(k) balance by age
As you might expect, the number of years you've had to work and save has a huge effect on the amount in your 401(k). To see where you start, check out your cohort below, and remember that the median is usually more indicative of where you stand than the mean.

It's again worth pointing out that even $200,000 might not be enough for many retirees. Although Social Security, pensions, and any IRAs will help augment this figure, $200,000 in your 401(k) translates to just $8,000 per year in retirement.

Average 401(k) balance by income
Next, let's investigate the role that your income plays in your 401(k) balance.

Again, the general trend plays out as expected -- the more you earn, the more you are able to put away in your 401(k). That being said, the main point of interest for many is seeing where they lie compared to others in their cohort.

Don't pat yourself on the back too quickly
While you might be feeling pretty good about where you stand against your peers, even the mean 401(k) balance will likely provide less than some retirees realize. That doesn't mean you should throw your hands up in the air or panic about your retirement savings.

Instead, you should focus on what you have control over. Fellow Fool Selena Maranjian recently outlined six steps you can take right now to shore up your retirement savings.

And I've long been a proponent of finding out your "enough" level. In essence, this means tuning out the commercialism that encourages rampant consumption, and finding out what you really need to lead a fulfilling life.

Almost always, such introspection creates a double-win in terms of retirement savings. First, it reduces your spending and -- therefore -- the amount of money you'll need for retirement. And secondly, it gives you more cash to invest in your 401(k) -- making it far easier to meet your needs in your Golden Years.

How one Seattle couple secured a $60K Social Security bonus -- and you can too
A Seattle couple recently discovered some little-known Social Security secrets that can boost many retirees' income by as much as $60,000. They were shocked by how easy it was to actually take advantage of these loopholes. And although it may seem too good to be true, it's 100% real.

In fact, one MarketWatch reporter argues that if more Americans used them, the government would have to shell out an extra $10 billion... every year! So once you learn how to take advantage of these loopholes, you could retire confidently with the peace of mind we're all after, even if you're woefully unprepared.
