Certificates of deposit (CDs) let you deposit your money for a predetermined amount of time at a fixed interest rate and collect your earnings when they mature. Historically jumbo CDs — which may have minimum deposit requirements in the realm of $100,000 — paid the best rates, but these days you don’t need to sink the big bucks into a jumbo CD to access great rates. “Jumbo CD rates tend to be slightly better than regular CD rates when you’re comparing options at the same bank, but they’re not the best deals out there,” Chanelle Bessette, banking specialist at NerdWallet, says, adding that “the best CD rates tend to have far lower minimums.”
