How we rank. We normalise every plan to a cost per terabyte per month at the size you pick, so a 2TB plan and a 5TB plan compare fairly. Annual billing is usually cheaper than the monthly figures shown, and bundles (Office 365, a phone plan) can change the value. Prices are indicative USD, checked periodically, confirm on the provider's site.

Lifetime plans, do they pay off?

A lifetime plan is one payment instead of a forever bill. Here's how long until it beats the equivalent subscription, after that, it's effectively free storage.

PlanStorageOne-timevs subscriptionBreaks even
Most people keep cloud storage far longer than the break-even point, so if you're sure of the provider a lifetime plan usually wins, and there's no annual renewal to forget. pCloud, Internxt and Icedrive are the main providers still offering them.
