About this gig
Most websites lose customers because they don't clearly show value.
I build custom ROI and pricing calculators that turn your Excel sheets, pricing logic, or ideas into interactive tools that help visitors instantly understand your value and take action.
These calculators are designed for one purpose: to increase conversions and generate leads.
Whether you run a SaaS product, service business, or agency, I can create a tool that fits directly into your landing page and helps you convert more visitors into customers.
You can collect leads, display dynamic pricing, show ROI results, and improve user engagement - all with a clean, responsive design that works on any device.
Just send me your idea, spreadsheet, or pricing model, and I will turn it into a fully functional web calculator tailored to your business.

FAQ
How long does it take to convert my Excel into a web calculator?
Most projects are done within 3-5 days, but complex calculators might need a week. I'll give you an exact timeline once I see your spreadsheet!
What if my Excel has tons of formulas and complex calculations?
Perfect! The more complex your formulas, the more impressive your final calculator will be. I love a good challenge!
Can visitors use my calculator without creating accounts or downloading anything?
Yes! Your calculator works instantly in any browser. No downloads, no signups required; unless you want to capture leads, which I can set up too.
What happens if I want changes after you deliver the calculator?
Minor tweaks and bug fixes are always free. Bigger changes like new features or design overhauls would be a small additional cost, but I'm flexible!
Do I need to know coding to manage my calculator after it's built?
Not at all! I'll show you how to make simple updates, and most changes happen automatically. If something breaks, just ping me; I've got your back!

Milan absolutely smashed it. The “useful life calculator” was my very first project with him, and I honestly never expected it to turn out this good — it’s an absolute game-changer. Super professional, lightning-fast, and the end result is a total knockout. Highly recommended! Please have a Look: https://estimado.de/nutzungsdauer-gutachten-fuer-immobilien/
