Read the fine print: Understand overdraft protection. “Some banks charge an upfront enrollment fee, and many customers are surprised to find there are additional fees when they overdraft.

Speak up: Adviser commission costs can be buried in your contract. “Request your adviser put in writing their fees and commissions,” says Scott Puritz, managing director of Rebalance IRA in Palo Alto, California.

Be suspicious: Even something like honeymoon and cash registries can be complicated. “The fees are varied and confusing. Many registry fees are passing along not just credit card fees but additional hidden fees, some as high as 11 percent, and couples do not realize it until they attempt to withdraw the money they’ve received,” says Nevin Shetty, CEO of BlueprintRegistry.com.

Says Dan Schneider, CEO of SIB Fixed Cost Reduction in Manhattan, “The advice is simple: Pay attention to the items in your bill. If you don’t know what the fees are for, ask. Make sure you are still using everything you are paying for, and have a professional look over your bills.”
