About this gig
Have a pricing formula, ROI model, or spreadsheet that your customers struggle to use?
I will turn one approved formula into a clear, branded website calculator that runs entirely in the browser. It is delivered as one standalone HTML file with no database, subscription, or external API.
This package includes:
- Up to 8 inputs and 4 outputs
- Up to 10 conditions or pricing tiers
- Your colors, labels, units, defaults, and CTA
- Responsive layout from mobile to desktop
- Input validation and reset behavior
- Three buyer-approved acceptance test cases
- One standalone HTML file
- Desktop and mobile screenshots
- One revision within the original scope
Please provide an approved formula or spreadsheet and three expected results. I implement your business rules; I do not decide whether those rules are commercially, financially, or legally correct.
Hosting, backend features, accounts, saved results, email, PDF generation, payment, CRM, analytics, and website installation are not included unless agreed in a custom offer.
Some website builders restrict custom JavaScript. Send your website platform before ordering if you are unsure.
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.

I turn approved spreadsheets, formulas, and business rules into clear, responsive website calculators. I build quote, ROI, pricing, and profit tools that run directly in the browser and match your brand. Each project includes clean inputs, validation, tested outputs, mobile-ready layout, and a standalone HTML file. You provide the approved formula and expected results; I implement the logic carefully and verify it against your test cases. This service is ideal for businesses that need a focused calculator without a database, subscription, or full software project.
FAQ
Will you create the business formula for me?
I can organize a formula you provide, but the package requires buyer-approved rules and expected results. Business, financial, legal, and tax assumptions remain the buyer's responsibility.
Can it work on any website?
The calculator is delivered as a standalone HTML file. Many sites can embed or adapt it, but some builders restrict custom JavaScript. Share the platform before ordering if installation is important.
Does it store customer data?
No. The calculator runs locally in the visitor's browser and does not include a database, analytics, CRM, or form submission.
Is website installation included?
No. Installation can only be quoted after checking the website platform, access method, and technical restrictions.
What counts as one revision?
Corrections to the agreed formula, labels, colors, and layout are included. New inputs, rules, modes, integrations, or changed business logic require a new quote.
