## RATE Function

The RATE function in Google Sheets calculates the interest rate per period of an annuity, given the number of periods, payment per period, present value, and future value.

### Syntax

```
RATE(number_of_periods, payment_per_period, present_value, [future_value], [end_or_beginning], [rate_guess])
```

`number_of_periods`

: The total number of payment periods.`payment_per_period`

: The amount paid in each period.`present_value`

: The present value of the loan or investment.`future_value`

: (Optional) The desired future value of the loan or investment. Default is 0.`end_or_beginning`

: (Optional) Indicates when payments are due. 0 for end of the period, 1 for beginning.`rate_guess`

: (Optional) Your guess for what the rate will be. Default is 0.1 (10%).

### Examples

**Basic Interest Rate Calculation**

Calculate the interest rate for a loan with monthly payments:

```
=RATE(60, -200, 10000)
```

This will output 0.03 or 3%.

### Notes

- Useful for determining the interest rate when payments are fixed.
- The result is an interest rate per period.
