What Cloud Migration Actually Costs in 2026
Ask three vendors for a cloud migration cost estimate and you'll get three numbers off by an order of magnitude. The lift-and-shift quote from a managed service provider lands at $40k. A boutique cloud consultancy quotes $180k for the same workload. Your AWS account manager says it'll "depend on usage." None of them are lying. They're answering different questions.
We've run enough of these for SME clients across India, the US, and the UK to spot the pattern. The honest answer for a mid-sized SME moving 20 to 50 workloads off self-hosted or legacy hosting in 2026 sits somewhere between $35,000 and $250,000 for the project itself, plus a 12-to-18-month run rate that often surprises finance teams more than the migration line item does.
This guide breaks down where the money actually goes, what the 2026 pricing tables look like across AWS, Azure, and Google Cloud, and the line items most quotes quietly omit.
What's Driving Cloud Migration Pricing in 2026
Two forces have reshaped cloud migration cost since 2024. First, vendors finally raised egress and inter-AZ traffic prices after years of warnings, with AWS data transfer rates going up 11% last year and Azure following within a quarter. Second, a wave of cloud repatriation projects from companies that over-committed in 2020 has made buyers more skeptical and more knowledgeable. That's good news for SMEs. It means cloud sales teams negotiate harder, and discounts that used to require a $500k spend now appear at $150k.
The other shift is internal. Most SMEs we work with don't have a FinOps function. They have an engineer who also handles billing. That's fine for a first migration. By month nine, it's the reason their cloud bill is 40% higher than the original estimate. Right-sizing, reserved instances, and savings plans are not exotic levers, but they need an owner. Without one, the bill drifts.
Honestly, half of the "surprise" cloud bill stories we hear are not surprises at all. They're predictable line items that nobody wrote down in the original budget.
The Five Migration Patterns and What Each Costs
Gartner's 5 Rs framework for cloud migration (rehost, replatform, refactor, repurchase, retire) still maps cleanly to budget reality. Here's what each pattern typically costs for an SME workload bundle in 2026:
| Pattern | What you do | Per-workload cost | Timeline |
|---|---|---|---|
| Rehost (lift & shift) | Move VMs as-is to EC2 / Azure VM / Compute Engine | $1,500 to $4,000 | 2 to 4 weeks |
| Replatform | Swap database to RDS, containerize the app | $4,000 to $12,000 | 4 to 8 weeks |
| Refactor | Rewrite for cloud-native (serverless, managed services) | $15,000 to $60,000 | 3 to 6 months |
| Repurchase | Replace with SaaS (e.g., on-prem CRM moves to HubSpot) | License cost + 2 to 6 weeks integration | 1 to 3 months |
| Retire | Decommission unused systems | ~$500 audit per system | 1 to 2 weeks |
Most SME migrations are not one pattern. They're a mix. A typical project might rehost 12 workloads, replatform 4, refactor 2, and retire 8 (yes, you'll almost always find systems running that nobody remembers turning on).
The pattern most over-sold to SMEs is refactor. Hyperscale sales teams push it because cloud-native workloads consume more managed services, which means more revenue for them. For an SME with 30 workloads, refactoring all of them is rarely the right move. We typically recommend refactoring only the 2 or 3 workloads that are growth-critical, and rehosting the rest. The savings show up in year two, when you're not paying off a refactor mortgage for systems nobody touches.
The Hidden Line Items Vendors Don't Quote
Here's what almost every initial cloud migration cost estimate leaves out:
- Discovery and dependency mapping. Before you migrate anything, somebody has to figure out what talks to what. Budget $8,000 to $25,000 for a real discovery phase. Vendors who skip this are setting up a Q3 surprise.
- Data egress during migration. Moving a terabyte costs different things on different days depending on transfer service, region, and time. Snowball-style appliances can be cheaper than online transfer over 10 TB.
- Network re-architecture. VPC design, transit gateway charges, VPN tunnels back to on-prem — easily $5k to $20k of work nobody mentions.
- Staff training and certification. Your in-house ops team will need AWS Solutions Architect, Azure Administrator, or GCP equivalent training. Budget $2,000 per engineer per cert.
- Post-migration optimization. The first three months after cutover, your bills will be 20 to 40% higher than steady state. Right-sizing happens after you have real telemetry.
- Multi-cloud audit and security review. Especially for SMEs in regulated sectors (healthcare, fintech), a SOC 2 or HIPAA review of the new posture is non-negotiable. Add $10k to $30k.
When you stack these up, the real migration cost often runs 1.7x to 2.2x the headline quote. The honest vendor tells you this up front. The dishonest one wins the bid and bills you for it later.
How to Estimate Your Cloud Migration Cost Without a Vendor
You don't need a paid assessment to get a defensible first-pass number. Three inputs will get you within 25% of reality:
- Workload count and complexity. Walk the data center, list every server, database, and batch job. Tag each as simple, moderate, or complex.
- Data volume and egress profile. How much data moves in and out, where to, and how often. AWS, Azure, and GCP all publish calculators. Use them with real numbers, not vendor-supplied projections.
- Steady-state cloud spend estimate. Use the AWS Pricing Calculator or the equivalent for your target cloud, with right-sized instances, not your current on-prem-equivalent sizing.
Multiply your workload count by the per-pattern cost from the table above, add 40% for hidden items, and you'll be in the right zip code. We've used this back-of-envelope method for client scoping calls for three years; it lands within 20% of the final number more than nine times out of ten.
Our IT consulting team can run a structured discovery if you want a higher-confidence number, but for an initial board conversation, the back-of-envelope is enough.
How SMEs, Startups, and Decision-Makers Should Approach the Budget
The right approach to cloud migration cost depends on who's asking.
SME owners should treat cloud migration as a 24-month investment, not a one-time project. The migration line item is roughly 30% of total cost over two years; the run rate is the other 70%. Insist on a two-year TCO from any vendor, not a one-line migration quote.
Startup founders with under 20 workloads have a different problem. The cloud is rarely the cheapest option for early-stage compute, but it's almost always the right operational call. Don't over-optimize the migration cost. Optimize for engineering velocity instead. If you're picking a cloud as a first-time founder, our framework for in-house vs outsourced decisions applies to cloud staffing too.
IT decision-makers (CTOs, VPs of engineering) should focus on three risks: vendor lock-in (use abstraction layers where the trade-off makes sense — they often don't), security posture transition (your perimeter model changes), and skills transition (your ops team's job description is changing). Each of these has a budget impact bigger than the migration line.
Developers doing the work: build a migration runbook per workload before touching anything. The runbook is your insurance policy. We've watched two-engineer teams ship a 40-workload migration in 14 weeks with discipline, and we've watched eight-engineer teams burn 6 months on the same scope without it.
If you want help framing the budget, our cloud computing practice handles end-to-end migration planning and can give you a sober TCO before you commit. We also handle the post-cutover DevOps and FinOps work that determines whether you save money in year two or watch the bill drift up.
Frequently Asked Questions
Is cloud migration cost lower on AWS, Azure, or GCP?
For a clean rehost, the three are within 10% of each other. Where they diverge is in managed services. Azure has the best pricing for Microsoft-heavy stacks, GCP wins on data and ML workloads, and AWS has the broadest discount programs for committed spend. For an SME with mixed workloads, vendor choice rarely changes the migration cost by more than 8%.
What's a realistic timeline for migrating 30 workloads?
Four to seven months end-to-end, including discovery and a two-month stabilization period after cutover. Anyone who quotes you under three months for that scope is either skipping discovery or refactoring nothing.
Should we use a vendor's free migration program?
Sometimes. AWS, Azure, and Google all offer credits, professional services, and partner co-funding for committed migrations. The catch is that those programs come with multi-year usage commitments. They make sense if you've already decided on the cloud and committed to scale. They don't make sense as a free way to try cloud.
What's the biggest hidden cost we should plan for?
Data egress and post-migration right-sizing. Egress bills surprise people during cutover, when traffic patterns are temporarily abnormal. Right-sizing surprises them three months in, when the first month's bill arrives with all the "we'll optimize later" instances still running on m5.2xlarge instead of m5.large.
How do we know we're getting a fair cloud migration quote?
Ask the vendor to break the quote into discovery, migration execution, optimization, and run-rate. Then ask what their assumptions are about your workload count, data volume, and target patterns. A vendor who can't itemize that breakdown is selling you a number, not a project.
Final Take
Cloud migration cost in 2026 isn't mysterious. It's just unevenly disclosed. A defensible budget for an SME moving 20 to 50 workloads sits between $35k and $250k for the project, plus a two-year run rate that adds 1.5x to 2x on top. The number depends mostly on how much refactoring you take on, how much data you move, and how disciplined your post-migration FinOps practice is.
