Legacy Software Modernization Cost Calculator

Modernization cost depends on what you keep, what you replace, and how clean the current data and integrations are.

About 5 minutes · Planning estimate, not a quotation

How the estimate is calculated

Uses the software cost engine with a modernization base. Rebuild and complex migration choices raise both cost and weeks.

Assumptions

Assumes a scoped product with one primary workflow set, a competent delivery team, and no unexplained legacy constraints. Discovery, change requests and third-party licence fees sit outside the range unless selected.

Limitations

The calculator cannot see your current systems, contracts or compliance evidence. Unusual integrations, regulated data and compressed timelines can move a project well outside this range.

Frequently asked questions

Is this a fixed project price?

No. It is a planning range for discussion. A quotation needs discovery, written scope and delivery constraints.

Why is there an MVP range and a full-platform range?

Most teams release a first useful version, then add secondary modules. The MVP range reflects that first release; the full range includes the wider selected scope.
