# NOMINAL

Returns the nominal annual interest rate, given the effective rate and the number of compounding periods per year.

## Syntax

```
NOMINAL(<effect_rate>, <npery>)
```

### Parameters

Term | Definition |
---|---|

effect_rate | The effective interest rate. |

npery | The number of compounding periods per year. |

## Return Value

The nominal annual interest rate.

## Remarks

The relationship between NOMINAL and EFFECT is shown in the following equation:

$$\text{EFFECT} = \Big( 1 + \frac{\text{nominal_rate}}{\text{npery}} \Big)^{\text{npery}} - 1$$

npery is rounded to the nearest integer.

An error is returned if:

- effect_rate ≤ 0.
- npery < 1.

This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
