See how a cost estimate is built.
CostClar is a Romanian platform for exploring costs before committing to a purchase or project. Its calculators cover questions such as energy use, home upgrades, and heating choices. Visitors can adjust inputs and inspect how the estimate is derived.
Each calculator exposes its inputs, method, assumptions, exclusions, and sources. Where a result depends on uncertainty, the platform presents scenarios rather than one guaranteed amount. The tools support exploration; they do not replace an invoice, supplier quote, or the visitor’s own research.
Application scope
- Custom web application and interactive cost calculators.
- Calculation models with documented assumptions and sources.
- Scenario-based estimates with visible limits and exclusions.
- Decision pages that connect calculation methods, evidence, and a specific question.
The application connects interface, calculation method, and supporting evidence: visitors can change their inputs, see how an estimate responds, and follow its sources and limitations. The public platform is live at costclar.ro.
