What is 50% per month?

"50% per month means you get half of something every month."

Imagine you have a big cookie jar full of cookies. Every month, your friend gives you half of the cookies in the jar. That’s like getting 50% per month, it's always half of whatever is there.

Suppose you and your best friend each have a bag of candy. If your friend says, "I’ll give you 50% of my candy every month," that means every month, you get half of their candy. So if they had 10 candies, you’d get 5. Next month, if they still have 10 candies left, you'd get another 5.

Or think about growing a plant. If your plant grows by 50% each month, that means it gets half bigger every month. So if it was 2 feet tall in January, it would be 3 feet tall in February (because half of 2 is 1), and then 4.5 feet tall in March, growing like a happy, healthy plant!
