Many people are uncertain how to start saving for retirement. If you haven't made saving a major part of your financial life up until now, it's hard to take up a new habit. Plus, there are so many myths about the best ways to save, and they can make retirement planning more confusing than it needs to be. Here's a look at some of the most common misconceptions—and the truth behind how to start saving for retirement now.

Myth #1: Only save if your employer offers a retirement plan

If your employer offers a match on your retirement savings, it's almost always a good idea to opt in. By doing so, you're effectively taking advantage of free money being contributed into your retirement plan while you put away your own money.

But if you don't have this benefit, saving for retirement on your own is absolutely still worthwhile. Thanks to the power of compound interest, your money can grow over time. If you invest over several decades, you can end up with a significant nest egg.

To see how powerful compound returns are, take a look at an example using a compound interest calculator. Suppose you start saving for retirement at age 28 and invest $250 per month. If your money earns a return of 6% per year, and you keep saving steadily until age 65, you'll have more than $381,000 when you reach retirement age.

In addition to traditional retirement savings, it's also good to consider contributing some of your income to a Roth IRA if you're eligible to do so. A Roth IRA can provide several layers of benefits in saving toward your retirement goals, including potential tax benefits down the line and more flexibility when it comes to withdrawing funds.

Myth #2: Don't save until you're earning more

Sometimes when people aren't sure how to start saving for retirement, they put it off, assuming that they can just catch up later. Unfortunately, this can be a costly mistake. The longer you wait to start saving, the less you can harness the power of compound returns.

Consider another example. Maybe you don't start investing $250 per month at age 28. Instead, you wait until age 45 when you have higher earnings. You now start investing $600 per month and continue until age 65. In this case, you'll only have about $264,000 in retirement savings—a shortfall of more than $117,000 compared to what you would have accumulated if you'd started earlier with smaller monthly contributions.

Ultimately, it’s important to start with what you can. The key is to maintain a disciplined approach and to remain committed to increasing that amount whenever there are salary increases, holiday or special bonuses, payoffs of other obligations, or debts and household costs that go away. Over time you can look back and be proud of the sustained activity and the accumulation you fed throughout the years.

Myth #3: There's an ideal percentage of income for saving

It's understandable if you feel unsure about how much to save. It can take some time to learn about retirement planning and to figure out the best savings rate for you. You may find it helpful to use a retirement savings calculator to explore possible scenarios and get a feel for what level of monthly retirement contribution would make sense.

However, even if you're still coming up with a plan, it's important to begin saving to take advantage of compound returns. Starting early in order to save as much as you're currently able to is better than waiting until you've determined the perfect savings rate. Remember, you can always change the amount you set aside each month going forward—but you can't go back in time and make up for a year when you didn't save at all.

Myth #4: You'll get Social Security, so there's no need to save

It's reassuring to know that Social Security benefits can replace some of your income when you retire. But being eligible for Social Security doesn't mean you don't have to save. According to the Social Security Administration, people typically need about 70% of their pre-retirement income to live on in retirement. So if you're making $50,000 a year, you probably need about $35,000 a year when you're retired, or a bit more once you take into account factors like inflation. And some estimates suggest you might need 80% to 90% of pre-retirement income to cover expenses once you're no longer working.

Social Security benefits usually replace around 40% of pre-retirement income for the average person. So in general, you can't count on Social Security benefits to completely meet your needs in your golden years.

Myth #5: It's too late if you didn't start saving in your 20s or 30s

Building up savings early is ideal, but it's never too late to begin preparing for retirement. If you're close to retirement age, the Department of Labor recommends cutting your spending so you have more money available to save. You may also want to look into catch-up contributions, which allow people who are over age 50 and enrolled in certain eligible retirement plans to contribute more money than the usual limits. Those catch-up contributions for employer-sponsored plans can be up to 33.3% more than the usual limits, allowing you to be more aggressive with your saving strategy.

No time like the present

The truth is, there's no time like the present to start saving for retirement. Whether you've just embarked on your career or have been in the workforce for years, you might benefit from a tax-advantaged retirement account like a traditional or Roth IRA. Understanding your full options for retirement savings plans will help you decide which path is right for you as you look towards your future.
