Both business owners and employees over age 70 1/2 must take required minimum distributions from a SEP-IRA or SIMPLE-IRA. 

The link above has all the information you need to calculate and plan.

Required minimum distributions (RMDs). For distributions required to be made after December 31, 2019, the age for beginning mandatory distributions is changed to age 72 for IRA owners reaching age 70 ½ after December 31, 2019. The required beginning date for IRA owners who haven't reached age 70 1/2 by the end of 2019 is April 1st of the year following the year of the owner’s 72nd birthday.

The amount is the prior years ending account value divided by the age factor in the table III.
