I will build custom web calculators


About this gig
I build custom web calculators using HTML, CSS and JavaScript for business, finance and health purposes.
Interactive calculators are a great way to improve user experience, increase engagement and provide real value to your visitors.
I can create tools such as ROI calculators, BMI calculators, percentage and discount calculators, or any custom logic you need.
All calculators are:
- Fully responsive (mobile-friendly)
- Clean and user-friendly
- Fast and lightweight
- Easy to integrate into your website
Depending on the package, I also offer custom design, validation, copy/reset features and advanced UI improvements.
Each order includes one calculator. You can add more using gig extras or request a custom offer for multiple calculators.
If you are not sure about the formula or structure, I can help you define it.
