Transfer General · Cost calculators

What cross-cloud data transfer actually costs — before and after you build it.

Four models. Your numbers. No product pitch — these calculators stand on their own. Adjust the inputs; the math is visible and the assumptions are documented.

Model 01

—

Initial build + 3-year TCO

Model 02

—

Maintenance labor / year

Model 03

—

Audit evidence labor / year

Model 04

—

Egress waste / year

Model 01 / 04

Build cost

Initial build cost — DIY transfer pipeline

Building a cross-cloud transfer pipeline with object-layer encryption, integrity verification, and audit evidence. This calculator estimates the engineering investment — including the things teams routinely de-scope.

Assumption

160 hr / eng-month

Scope

Build + annual maintenance + annual audit labor

Output

3-year TCO estimate

Complexity spike: Moving from 2 clouds to 3 triples the integration surface — 3 cloud pairs instead of 1. Three IAM models, three SDK integrations, three failure modes.

Your environmentBuild assumptions

Senior engineer hourly rate

$175/hr

Number of clouds

2 clouds

Regulated deployment

No

Adds FIPS-validation engineering overhead.

Cloud pairs

1

2 clouds = 1 pair · 3 clouds = 3 pairs.

Maintenance labor

Monthly maintenance — steady-state pipeline labor

Once the pipeline exists, teams still carry ongoing engineering cost: SDK drift, cert rotation, failure-handling upkeep, research across CSP changes, and recurring validation for regulated deployments.

Base monthly hours reflect steady-state operations on a working pipeline. Figures exclude initial build, incident response for production outages, and cross-team coordination overhead.

Model 03 / 04

Compliance cost

Audit evidence compliance cost labor

When an auditor asks for proof that a specific object moved intact between clouds, someone must reconstruct what happened — identifying object versions, reconciling partial transfers, validating integrity across disconnected CSP audit trails, and assembling it into evidence an auditor will accept.

Scope

Scheduled + ad hoc

This model covers labor only — the engineering time spent reconstructing transfer evidence. It does not include the cost of audit findings, remediation, delayed certifications, or regulatory penalties.

Model 04 / 04

Egress cost

Egress waste from failed transfers

When a cross-cloud transfer fails mid-stream, the data already moved is billed at egress rates — and must be re-transferred from scratch. This calculator estimates the annual cost of that wasted egress.
