I will build a custom interactive financial calculator or simulator for any purpose
Claudio Dinis
Sobre este Serviço
Need an interactive tool for a specific financial calculation something that doesn't exist off-the-shelf because it's unique to your business?
I build custom web-based calculators and simulators (HTML/JavaScript), tailored to the exact problem you need solved. Not a generic template the calculation logic is designed around your specific case.
Examples of what I can build:
- Personal or business budget simulators
- Cash-flow and treasury projection tools
- Loan/credit amortization simulators
- ROI, margin, or break-even calculators
- Pricing tools for products or services
- Commission or bonus structure simulators
- Interactive financial dashboards with multiple KPIs
Have a different idea? Get in touch if it involves numbers, formulas, and financial decisions, I can probably turn it into an interactive tool.
As an accounting technician with hands-on ERP experience and years working with real financial data, I make sure the logic behind the tool is correct not just a nice interface, but math that actually makes sense for your business.
Delivered as a standalone file (works in any browser, no server needed) or adapted for direct embedding on your website.

Perguntas frequentes
Do I need any technical knowledge to use the tool once delivered?
No. The tool works like any regular webpage — you or your clients just open it in a browser and use it. No installation, no coding knowledge required.
Can the tool be embedded on my existing website?
Yes. I deliver a standalone file by default, but I can also adapt it for direct embedding into your site if needed — just let me know when placing your order.
What if my idea isn't listed in your examples?
That's fine — the examples are just a starting point. If it involves numbers, calculations, and financial logic, send me the details and I'll confirm if it's something I can build.
Will the calculations be accurate for my specific use case?
I design the calculation logic around your exact requirements before writing any code, and I test it with real numbers before delivery. If something doesn't add up, we fix it as part of the included revisions.
