Why CostRatio Exists

Cloud storage pricing is surprisingly hard to compare. Providers scatter their pricing across confusing plan tiers, hide renewal fees, and make it difficult to calculate how much you're actually paying per gigabyte.

CostRatio.com was built to cut through the noise. The goal is simple: calculate the exact price-to-capacity ratio ($/TB) and feature index across 18+ major providers — updated daily, with no spin or marketing fluff.

Our Methodology: Real-World Testing

We don't just aggregate data; we live it. Our team maintains active accounts with top providers to test real-world upload speeds, mobile app responsiveness, and zero-knowledge encryption claims. When we benchmark a provider, it's based on verified specs and active pricing audits.

Our automated systems check provider pricing pages daily to ensure accuracy. We track:

  • Monthly and annual subscription prices
  • Free tier offerings and storage limits
  • Price per terabyte ($/TB) for normalized value comparison
  • Key features: end-to-end encryption, file versioning, collaboration tools
  • Bandwidth and egress fees for object storage

When prices change, we update the database within 24 hours. The "last updated" timestamp shown throughout the site reflects the most recent data refresh.

Our Independence

CostRatio.com is an independent benchmark site. We are not affiliated with, sponsored by, or in a paid relationship with any of the cloud storage providers listed on this site. Provider links are provided purely as a convenience — we do not accept payment to artificially alter rankings or ratings.

This site is supported through standard Google AdSense display advertising. Advertisements shown on this site are served by Google and are clearly distinguishable from our editorial content. They do not influence our rankings, recommendations, or the data we display.

The CostRatio Index Methodology

Prices are sourced directly from each provider's official pricing page. Where a provider offers both monthly and annual billing, we display both. The "$/TB/month" value we calculate normalizes all plans to the same unit, making it easy to spot genuine value regardless of plan size.

Ratings are our editorial assessment based on publicly available reviews, feature sets, reliability track records, and pricing competitiveness — not paid placements.
