FAQ
Do you use calculator plugins to build these?
No. I write custom code for every project. Plugins are often slow, limited in their mathematical capabilities, and difficult to style to match your brand. Custom code ensures the calculator looks exactly how you want it, runs lightning-fast, and scales with your business.
Will this calculator work on my WordPress or Shopify website?
Yes. Because I write custom code (HTML/CSS/JS or React) rather than relying on restrictive platform plugins, the calculators I build can be seamlessly embedded into any website platform, including WordPress, Shopify, Webflow, or custom-built sites.
I only have my logic in a messy Excel spreadsheet. Can you work with that?
Yes, absolutely. That is actually the most common starting point. You can send me your Excel or Google Sheet, and I will translate your complex formulas, VLOOKUPs, and conditional logic into clean, functional web code.
Can you send the calculated results to my email or CRM?
Yes. I can build lead-capture forms into the calculator and use API integrations or webhooks to send the user's data and their specific calculation results directly to your email, GoHighLevel, HubSpot, or any other CRM you use.
What if I need to update my prices or variables in the future?
I structure the code clearly so that variables (like base prices or interest rates) are easy to find and update. If you anticipate changing prices frequently, let me know, and we can discuss building a simple backend or connecting it to a database so you can manage the variables yourself without tou
Will the calculator be mobile-friendly?
Yes, 100%. A large portion of your traffic will be on mobile devices. I ensure every calculator is fully responsive, ensuring the inputs, sliders, and results look and function perfectly on any screen size.
Can the calculator generate a PDF quote for the user to download?
Yes. For advanced builds, I can integrate functionality that takes the user's inputs and calculation results and instantly generates a professionally styled, branded PDF report or quote for them to download or receive via email.
What exactly do you need from me to start?
To get started, I need the mathematical logic (a spreadsheet or clear list of formulas), a brief explanation of what the calculator should achieve, any brand guidelines or design inspirations you have, and details on where the calculator will be hosted.
