The monthly growth rate is the annual growth rate divided by 12, because there are 12 months in a year.

monthly rate = 15% : 12

monthly rate = 15/100 : 12

monthly rate = 15/100 * 1/12

monthly rate = 15/1,200

monthly rate = 1.25/100

monthly rate = 1.25%

The monthly growth rate is 1.25% or approximately 1.3%
