Frequently Asked Questions

Use the frequency specified by the account or loan. More frequent compounding produces a slightly higher effective return when the nominal rate is unchanged.

Does this calculator include regular deposits or withdrawals?+

No. It models one starting principal with no additional contributions or withdrawals.

What is the difference between nominal and effective annual interest?+

The nominal rate is the stated annual rate. The effective annual rate includes the impact of compounding during the year.
