Why this page matters

CD searchers usually want one clear answer: what will this deposit be worth at maturity under a given bank rate and term.

Compounding frequency matters because the same quoted annual rate can produce slightly different effective yield depending on how often interest is credited.

Frequently asked questions

Why does compounding frequency matter?

Because more frequent compounding credits interest sooner, which slightly increases the effective annual yield and maturity value.

Can I use this for brokered CDs too?

Yes, as long as the rate and compounding assumptions are clear and you are not trying to model call features or early sale pricing.

Does this include early withdrawal penalties?

No. This version estimates standard maturity value only and does not deduct early withdrawal penalties or taxes.
