While Apple previously offered iCloud storage in 5GB, 20GB, 200GB, 500GB and 1TB tiers, the new tiers include only 50GB, 200GB, or 1TB of storage at lower prices. With the old pricing, 20GB of storage in the U.S. cost $0.99, but now users will get 50GB for the same price. 200GB was formerly priced at $3.99 and is now $2.99, and 1TB of storage, previously priced at $19.99, is now $9.99.
Pricing in 24 countries in the Middle East, Asia, and Europe are included in the support document. Countries where local currency isn't supported will have storage upgrades billed in dollars, and Eurozone countries will be charged in Euros. For countries with Value Added Tax, VAT is included in the iCloud pricing.
Customers who purchased monthly plans before September 16, 2015, will have their accounts upgraded automatically, presumably when iOS 9 launches tomorrow. Customers on an annual plan will continue to renew annually at that rate.
