CD calculator: Are your CDs losing value to inflation?

As inflation rises, it becomes more important that your investments keep pace. Use this simple tool to see if your CD investments are gaining or losing value.

Inflation can run at a higher rate than many CD interest rates -- and when it does, your investments can actually lose value. This CD calculator shows how well your certificate of deposit is performing against inflation and lets you compare other CD options at the same time.

Know your CD's inflation-adjusted value at maturity

Inflation eats into the return you receive on any investment. Knowing how much can help you recognize which CD performs best against inflation and might help protect your assets. Your inflation-adjusted value at maturity tells you how much your current CD rate is likely to gain or lose relative to inflation over the life of your CD.

The calculator's default inflation assumption is based on the Consumer Price Index increase over the past 12 months. However, if you prefer to use a different inflation assumption, you can enter one manually.

Compare interest rates on CDs

Besides comparing your current CD rate to inflation, this calculator can also help you weigh your options. You can enter the interest rate for a new CD you're considering or see if our featured banks are offering one of the best CD rates for the amount you want to invest. Click on the bank's logo, if it appears, to automatically populate their current CD rate into the calculator for comparison.

Protecting your investments against inflation

In general, do CDs keep up with inflation? Historically, this has been far from a sure thing, though shopping for the best CD rates might give you a fighting chance. The CD calculator is designed to let you experiment with different options so you can easily evaluate results and refine your investment plan.
