The option to set an Interest rate on your child’s Pots is a feature included in our Rooster PLUS subscription.
To set an 'Interest Rate' on a Pot:
Go to the Pot you want to add interest to on your child's dashboard
Tap on the edit icon in the top right corner
Tap ‘Interest Rate’
From there you can add the interest rate % to be awarded for the money your child keeps in their Pot
Interest accrues over time with each deposit your child puts into their account, and gets rewarded on the first of each month.
