Software Development Cost Calculator
The cost of software depends on scope, complexity, integrations, quality targets and team structure, not on a per-screen rate. This guide sets out what moves an estimate and what to prepare. An interactive calculator is being prepared and no figures are quoted here.

Why a quick calculator can mislead
Two projects that both look like a mobile app can differ by an order of magnitude in effort. One has three screens and a simple back end; the other needs offline sync, payments, device integration and an admin console. Any figure produced without understanding those differences is a guess.
An interactive calculator is being prepared and will explain its assumptions. Meanwhile, Renvric produces estimates through a short discovery.
The main cost drivers
Scope and feature depth
A login screen and a role-based permission model are very different pieces of work.
Integrations
Every external system adds design, testing and dependency risk; poorly documented ones cost more.
Platforms and devices
Native iOS and Android, web and desktop multiply design, build and test effort.
Data and migration
Moving, cleansing and reconciling legacy data is often a project inside the project.
Quality and security needs
Regulated data, high availability and performance targets add engineering and testing.
Team and duration
Seniority mix, team size and time all affect the total, and rarely in a straight line.
Costs that are easy to overlook
- Hosting, monitoring, licences and third-party service fees after launch.
- Ongoing maintenance, dependency updates and security patching.
- Your own staff time for requirements, review and testing.
- Change management, training and documentation.
- Content creation and data preparation.
- Support during the first weeks after release.
Share the outcome you need and Renvric will recommend the smallest useful next step.
How a defensible estimate is built
A credible figure breaks the work into components, estimates each as a range, states assumptions, and adds explicit contingency for the unknowns. It separates what is certain from what depends on decisions not yet taken. Estimates that arrive on day one with no questions are rarely worth much.
Fixed prices are possible when scope is stable and acceptance criteria are written; time-based models fit changing scope. The choice shifts risk, not the underlying cost of the work.
A portal dependency example
Consider two quotes for a customer portal, one far lower. On inspection, the cheaper quote excludes data migration, assumes a single browser, and treats security testing as optional. Comparing like with like means asking each supplier to list what is in, what is out and what they assumed.
What to prepare for an estimate

- The business outcome and the users involved.
- A feature list, even if rough, marked as essential or desirable.
- Systems to integrate, with access to their documentation.
- Regulatory, security and performance requirements.
- A target date and an indicative budget range if you have one.
Common questions
Why is no price shown here?
Because honest software pricing depends on details that a form cannot capture, and a number given without them would mislead. Renvric produces estimates after a short discovery that clarifies scope, integrations and quality needs, and presents them as ranges with stated assumptions.
What information gives the best estimate?
A clear outcome, the users and their main tasks, a prioritised feature list, the systems to connect to, regulatory or security requirements and your target dates. Prototypes, wireframes, existing code and process documents are valuable. Where details are missing, the discovery identifies them.
When will the interactive calculator be available?
An interactive version is being prepared. When released it will explain its assumptions and give indicative ranges only, not commitments. For a figure you can plan around, a discovery-based estimate remains the more reliable route, and you can request one at info@renvric.com.
Is a fixed price or time-based pricing cheaper?
Neither is inherently cheaper. A fixed price carries a premium for the risk the provider takes, and works best when scope is well defined. Time-based pricing can cost less if requirements are fluid, but needs good steering. The right choice depends on how settled your requirements are.
How can I compare quotes from different suppliers?
Ask each to list inclusions, exclusions and assumptions, to break down the estimate by component, to state how changes are handled and to describe what happens after launch. A lower figure with more exclusions is not cheaper. Comparison is meaningful only when the scope is the same.
