I will build a custom web calculator, estimator or configurator
Eldar
About this gig
Need more than a static landing page? I will build a responsive custom calculator, estimator, or configurator that helps visitors understand a price, compare options, or reach a useful result.
Your interactive experience can include:
custom formulas and business rules
dynamic pricing, totals, ranges, or recommendations
multi-step inputs and option selectors
clear result breakdowns or visual feedback
mobile-responsive design
validation and helpful empty/error states
a mock/local lead form, or one agreed integration when scoped in advance
I build focused interfaces with React and TypeScript where they are a good fit, and provide the source code included in your package.
This service is ideal for cost estimators, pricing calculators, quote planners, product configurators, eligibility tools, and guided selection experiences.
Please contact me on Fiverr before ordering if your project needs an API, webhook, CRM, existing-site integration, authentication, backend work, or complex third-party logic. I will review the rules and constraints before confirming scope.
CAD, 3D/WebGL, AI recognition, full ecommerce, and large backends are not included in the fixed packages.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

FAQ
Can you build the logic from Excel or Google Sheets?
Yes. A clear spreadsheet can be an excellent reference for formulas, pricing tiers, and sample results. Please provide it before I confirm the scope.
Will the calculator work on mobile devices?
Yes. Every package includes a responsive interface designed for common desktop, tablet, and mobile layouts.
Can you add it to my existing website?
Often yes, depending on the platform, code access, and integration method. Please contact me on Fiverr before ordering so I can review the setup.
Can you connect an API, webhook, or CRM?
A simple agreed webhook or form integration can be included in Standard when scoped first. APIs, CRMs, authentication, and complex integrations require technical review and may need a custom offer.
Do the packages include CAD, 3D, or AI recognition?
No. Fixed packages do not include CAD, 3D/WebGL, AI image or floor-plan recognition, or other specialist processing.
Will I receive the source code?
Yes. Source code for the agreed deliverable is included in all three packages.
Should I contact you before ordering?
Please do if the rules are complex or the project needs an existing-site integration, backend, API, CRM, authentication, hosting, or third-party service.
