First, head to your Subscriptions Tab. You can view the renewal date under the 'Team Management' and the 'Billing' section.
You can then see exactly when your subscription will renew under the 'Renewal Date' column.
Scroll down to 'Upcoming Annual Subscription Renewals' or 'Upcoming Monthly Renewals' to view all subscription renewals at a glance.
Don't forget—you can always switch to Annual Billing on your subscription. The great news is that any unused time on the monthly subscription will be prorated to the annual subscription.
