Effective annual rate includes the effect of compounding within a year.
| Input | What it means |
|---|---|
| Annual interest rate | The quoted rate for the time basis shown in the form; an annual rate is not a monthly rate. |
| Compounding frequency | How often the event, payment or administration occurs; use the form’s stated schedule. |
A 12% nominal rate compounded monthly gives about 12.68% effective annual interest.
Compare the result with the underlying statement, budget or proposed transaction. It is most useful when every amount uses the same reporting period and the same accounting definition.
Use one consistent period for every amount and rate in the relationship. If a form specifies an annual rate or a monthly amount, follow that label rather than mixing time periods.
Only the costs and taxes represented by the inputs and formula are included. A real transaction can include other charges, so compare the estimate with the underlying agreement or statement.
