Inflation impact on 3-year CD rates

Inflation reduces the value of any savings or investment balance, including CDs. Your earnings have to exceed the inflation rate for there to be a real return on your money. While mid- and long-term CDs can lock in a high rate today, there’s still potential for inflation to lower your earnings.

For a more inflation-proof savings strategy, consider stock- and bond-based investment products. They can come in handy for long-term savings since their earnings have a better chance of exceeding the inflation rate.

Should I pay early withdrawal penalties if 3-year CD rates rise?

In today’s current rate climate, the odds don’t point to an increase in 3-year CD rates any time soon. That said, an early withdrawal can sometimes be worth paying the penalties, although you’ll want to do the math and check whether the gains are greater than the costs. Calculate the penalty you would end up paying and ensure it’s lower than the returns on the new CD. This early withdrawal penalty calculator from can run the numbers for you and tell you outright whether breaking your CD is worth it or not.
