Get ready to save more in 2018

You can save more for retirement next year using tax-advantaged accounts, thanks to a boost in the maximum 401(k) contribution rate by the IRS. The maximum rate increases by $500 to $18,500, which is the first increase in three years. Those aged 50 or older can still contribute an additional $6,000 on top of that amount.

This is good news, because a 401(k) is one of most potent tools in your retirement arsenal. It offers many benefits over other forms of saving, including:

* Tax-deferred growth. Pre-tax income of $18,500 invested over 30 years with 6 percent annual cumulative interest will grow to $111,901.92. That’s compared with $67,588.76 of the same amount of income invested after being taxed at the highest rate. While you’ll owe tax on 401(k) withdrawals after retirement, you may be able to manage your 401(k) withdrawals to fall into a lower income bracket.
