You can always upgrade or downgrade your plan anytime that suits your needs. Changing a subscription will result in a proration, not only for upgrading, but also for downgrading. Once you click on the Upgrade or Change Plan, you can preview the prorated changes or the credit amount according to your current billing period before you make the change. To be specific, we use 30 days a month to calculate the remaining days of existing and upgraded/downgraded plan in the proration system.
For example, you want to upgrade from Fresher to Rising Star, which is $9.79 /month and $15.32 /month respectively. Assuming the change occurred halfway through the billing period, you will be billed an additional $2.77 for the upgrade:
[$7.66 for half month of Rising Star plan] – [$3.395 for the unutilized fee charged for Fresher plan]
If you want to downgrade from High Achiever to Fresher, which is $43.56 /month and $9.79 /month respectively. Assuming you make the change halfway through the billing period, you will have a credit amount of $16.89 for the downgrade:
[$21.78 for half month of utilized High Achiever plan] – [$4.895 for half month of Fresher plan]
This credit amount of $16.89 will be used in your next billing. In this example, you will not be charged $9.79 again for your Fresher plan for your next renewal as you still have $16.89 of credit amount to be utilized.
