DataCamp has both monthly and yearly individual subscriptions. Assuming that you end up using DataCamp for an entire year, the month-to-month breakdown of a yearly subscription is more cost-effective than a monthly subscription. The main difference is that with the yearly subscription, you are charged for the entire year of service with one transaction.

Before signing up for a subscription, it is important to closely review all options. If you would like to sign up for a monthly subscription, be sure that you did not select Pay Annually.
