The billing cycle denotes the period during which you are charged for your subscription. It is the span between two successive billing statements.
The billing cycle may be either monthly or yearly, depending on the terms of your subscription.
For instance, if you've chosen a monthly subscription starting from May 5, 2021, your initial billing cycle will run from May 5, 2021, to June 4, 2021.
Likewise, if you've opted for an annual subscription, your billing cycle will extend from May 5, 2021, to June 4, 2021.
