A 401(k) rollover to an IRA offers a slew of benefits. With an IRA, you have a much wider range of investment options than you do with a 401(k). Most 401(k)s are limited to only a few mutual funds, while individual IRAs grant you the ability to choose between (but not limited to) various stocks, bonds, exchange-traded funds (ETFs) and mutual funds.
Opting for an IRA rollover also boosts your chances of saving more money in the long run. There are a number of hidden fees attached to a 401(k), such as administrative fees, investment fees and fund expense ratios. While your IRA won't be entirely free of fees, you can enjoy greater flexibility over how and where you invest. This allows you to save a considerable amount of money over time.
