Stop
paying for egress.
Drag two sliders, pick a source and a destination, and the calculator returns the twelve-month savings plus the migration payback period.
Egress fees on AWS, Azure, and GCP add up to real money — typically $0.09 to $0.12 per GB read from storage every month. Wasabi, Backblaze B2, Cloudflare R2, and Filebase charge zero egress within fair-use limits. The math underneath is below.
Egress Savings
See your twelve-month savings.
Move from a paid-egress provider to one with free egress and your monthly invoice shrinks. Plug in your data size and how much you read from storage each month — the calculator does the rest, including the one-time Mover migration cost.

Numbers use published standard-tier rates from each provider as of May 2026. Actual invoice varies by region, committed-use discounts, and your specific contract. Mover migration cost uses the cheapest combination of prepaid usage packs that covers the data size — packs stack, so a 2 TB migration is two 1 TB packs, not one 5 TB pack. The dry run prices the migration against your actual data and shows the exact one-time Mover cost before you commit.
Reads cost you, every month, on every byte.
Hot data with active read patterns — analytics workloads, media delivery, distributed teams pulling from storage — generates monthly egress that often exceeds the storage bill itself. AWS's $0.09 per GB, Azure's $0.0875, and GCP's $0.12 are the standard-tier rates; committed-use discounts reduce them but rarely eliminate them.
Zero egress flips the unit economics.
Wasabi, Backblaze B2, Cloudflare R2, and Filebase all charge zero egress (within fair-use thresholds), and their per-TB storage rates run a fifth to a third of the hyperscalers. The migration is the one-time cost; the savings recur every month for as long as the workload runs.
One-time fee, paid once, never again.
Mover charges per GB on a prepaid usage pack — $0.15 at 10 TB, $0.20 at 1 TB. That's the one-time line on your invoice for the migration itself. The calculator picks the pack that fits your data size and subtracts it from the twelve-month savings so the net number is honest.
