Legacy cost calculator
Every month that passes, your legacy system costs more to keep alive.
Find out how much you are spending to prop up a system that no longer keeps pace with your business — maintenance, lost productivity and missed opportunities, in a single number.
62%
of companies still run on legacy systems
Most of them have no idea what it is really costing.
The cost of your legacy system is not only on the maintenance invoice. It is in the hours your team burns on workarounds, in the initiatives that never leave the slide deck because the system can't support them, and in a security risk that keeps growing while nobody can put a number on it.
The data is clear: maintaining a legacy system gets 10 to 15% more expensive every year. Within two to three years, the cost of not modernizing overtakes the cost of modernizing.
Use the calculator below to see the real number for your case.

That number never stops growing.
Every year without modernization adds another layer of cost. And not only a financial one.
Maintenance that only gets pricier
IT budget spent keeping what already exists alive. What's left for innovation shrinks every year.
Security with no updates
Systems with no patches and no vendor support. A single breach can cost millions in fines, compromised data and a ruined reputation.
AI and automation blocked
Data locked in silos, with no modern APIs. Every artificial intelligence initiative hits the same wall: the foundation can't support it.
The knowledge is walking out the door
The people who know how to run your system are retiring. Fewer than 2,000 new developers specialized in legacy languages enter the market worldwide each year. When one of them leaves, the risk leaves with them.
Results in production
Companies that modernized stopped paying for the past.
Modernization is not a cost. It is the end of a cost you already pay — one that grows every month.
Maintenance cost drops
Companies that modernized report a 30 to 40% reduction in IT operating costs within the first year. The budget that propped up the legacy system starts funding innovation instead.
The team finally starts building
Developers who spent 42% of the week on workarounds and legacy fixes start shipping real features. The same team delivers more.
New technologies become possible
With a modern architecture, AI, automation and third-party API integrations stop being impossible projects and become natural next steps.
The Devmania method
From legacy to modern, without pausing your operations.
A phased, auditable process — from the first assessment to production delivery.
Assessment
We map your systems, dependencies and risks, and deliver a full report before any proposal.
Roadmap
We define the target architecture, the migration phases and the risk plan. You know exactly what will happen and in what order.
Development
Specialized teams work in parallel, with incremental deliveries and validation at every sprint.
Review
Two independent review stages before every delivery. Robust, documented, production-ready code.
Maintenance and scale
The system evolves alongside the business, with continuous support and new deliveries whenever needed.
15 years of real projects
We build systems that stay in production, not in presentations.
We work with complex systems across many industries. What we bring is a method proven in production.
Fixed scope before we start
User journey, business rules, flows and acceptance criteria defined before the first line of code. The project has a beginning, a middle and an end.
Architecture built for your stage
Every project starts with the right structure for your situation and growth. Modular, scalable and documented.
Phased migration, operation preserved
We modernize module by module. Your business keeps running while the transition happens.
Review before any deploy
No code reaches production without review. Separate environments and a controlled pipeline in every sprint.
ROI estimate before the proposal
You get the savings projection before any commitment. The decision is yours, with the numbers in hand.
Industries we serve
