Moving data between cloud regions — priced per GB, per region pair.
Inter-region transfer is $0.02–$0.14/GB by route, so replication and multi-region designs add up fast. Compare same-zone cost on the cross-AZ transfer calculator and public egress on the cloud egress calculator.
The Inter-Region Data Transfer Cost Calculator estimates what you pay to move data between cloud regions. It takes two inputs — the volume of data transferred per month (in GB) and the per-GB transfer rate charged by your provider — and multiplies them to produce your monthly bill, then scales that figure up to a yearly total. Inter-region transfer is billed separately from storage and compute, so the two drivers here are straightforward: how much data crosses regions and the rate applied to each gigabyte. Because the math is linear, doubling either input doubles the cost, which makes the calculator useful for quickly sizing the impact of replication, backups, or cross-region traffic.
The key trade-off to watch is that inter-region rates are often much higher than transfers within a single region, and small per-GB numbers add up fast at scale. A rate that looks trivial per gigabyte becomes a meaningful line item once monthly volume reaches hundreds or thousands of GB, and the yearly view makes that clear. Use the calculator before committing to a multi-region architecture: test how the total shifts as you adjust the GB moved, and consider whether some data can stay in one region or be transferred less frequently. Even a modest reduction in monthly GB compounds across twelve months into real savings.
Roughly $0.02 to $0.14 per GB, depending on the specific region pair. Transfers between nearby regions are cheap; cross-continent hops (e.g. US to Asia) are the expensive end. Providers price each pair differently, so check your exact route.
Keep chatty services in the same region, cache or replicate only what you truly need cross-region, compress payloads, and use a CDN for read-heavy content instead of serving cross-region. Multi-region active-active is powerful but bills every synchronized byte.
