Upgrade your iCloud storage
You can purchase additional iCloud storage from your iOS device, Mac, or Windows computer. For information about storage plan pricing and accepted payment methods, see the Apple Support article Storage upgrade pricing.
On your iOS device
Go to Settings > iCloud > Storage & Backup, then tap Buy More Storage or Change Storage Plan (whichever you see).
Choose the amount of storage you want, tap Buy (in the upper-right corner), then follow the instructions that appear.
On your Mac
Open iCloud preferences, then click Manage.
Click Change Storage Plan (in the upper right).
Choose the amount of storage you want, then follow the instructions that appear.
On your Windows computer
Open the iCloud Control Panel, then click Manage.
Click Buy More Storage or Change Storage Plan (whichever you see).
Select the amount of storage you want, then follow the instructions that appear.
If you purchase a higher-tier storage plan to replace your existing storage plan (for example, 20 GB to replace 10 GB), the existing storage plan will be canceled, and you’ll be charged the prorated cost for the upgrade (the cost of the higher-tier plan minus the prorated cost of the previous plan). The new storage plan is applied to your iCloud account and the renewal date is updated to reflect the purchase date for the new plan.
You are notified via email before you are billed each year for the renewal of your current storage plan.
