In today's lean times, some companies are trimming expenses by halting the employer match on their employees' 401(k) contributions. In a recent survey by benefits consultant Watson Wyatt, 2% of 248 U.S. companies have already cut back on matching contributions and another 4% plan on doing so. If you start looking to trim your own expenses when money gets tight, don't take the same approach.Long considered "free money" by many financial advisers, employer matches are a great motivator to get people to save for retirement. But the bulk of retirement savings still come from employee contributions. While dropping the match can help a company's bottom line, stopping your own contributions will hurt yours. Here's why: Missing out on even a couple of years of contributions now can leave you paying the price in retirement. To see just how much a hiatus from retirement contributions will cost you in retirement dollars, check out the online Delayed Savings calculator from BankingMyWay.com. To use the calculator, enter your current 401(k) balance, the number of years before you retire and your annual contribution amount. (You can also enter monthly or quarterly contribution amounts.) Next, enter the number of years you plan on suspending contributions and an estimate for a rate of return on your account.
