Hello-
I am in an industry that has a lot of calculations specific to the product size and I am wanting an interactive calculator app that allows me to make multiple calculators. I currently use Excel online and create the calculator and then share/embed it to my website. I find it doesn’t always work or has very slow response time at best.
The only real solution I see on the App store is Calconic Calculator Builder. Anyone have a calculator builder app they use with great success?
Thanks in advance.
The products are pumps and other pond industry-related calculations. I don’t need the calculations to link up to products necessarily at this time. I am really just looking for ways to calculate variables the customer would need for their pond, etc.
Thank you for your time!
Hi @CarA2021
You could try also looking at RFQ/RFQP, request for quote/proposal, type apps.
But most can be pretty byzantine because they are trying to be too broad for the most situations possible.
So can be really hard to setup if you needing excel level complexity.
But you probably need something custom; especially if there’s any visualization related aspects.
Either as a custom app.
Or just building this as a frontend theme customization using either product data, metafields, and or Metaobjects.
Mainly when it’s a series of inputs and not actually needing excel level formulas.
If you need this as a theme customization then contact me by my email for services or paid consultation.

Hi @CarA2021 
If Excel embeds are too slow, try Apippa – Custom Price Calculator. It lets you build multiple custom calculators, supports advanced formulas, and updates prices live on your product pages. Fast, flexible, and easy to use

Hi @CarA2021
You’re absolutely right — industries that require product-specific calculations (based on size, weight, dimensions, etc.) need something much more reliable and customizable than embedding Excel.
We’ve worked with similar cases at Mandasa Technologies, and based on our experience, here are a few solid options:
1. Calconic Calculator Builder
As you mentioned — it’s decent and user-friendly, but can be limiting for complex logic or when you need multiple calculators on different product pages.
- Custom Shopify Calculator App (Built via Shopify Functions or Liquid + JS)
For full control and speed, we’ve built custom calculators for many stores. They’re:
-
Fully embedded (no iframe issues like Excel)
-
Fast and responsive on both mobile/desktop
-
Can handle multiple formulas & product logics
-
Styled to match your theme perfectly
Example: A store selling flooring products had calculators for square footage, waste percentage, and price estimation — all handled dynamically per variant.
3. Easify Product Options (with math logic)
This is a newer app and supports conditional logic, quantity formulas, and field-based calculations — worth exploring if you don’t want custom coding.
Please note:
If your formulas are Excel-based, we can replicate them into JavaScript and fully integrate the calculator inside your product or landing pages.
Let me know if you have any questions!
Hi @CarA2021
If you’re looking for something more flexible than embedding Excel and want better performance, I’d recommend trying Easify Product Options. It supports custom pricing based on dimensions (like length x width), and you can set up interactive pricing formulas that update in real time as customers input their measurements.
You can also create multiple calculators across different products — all without needing to embed anything or worry about slow load times. Might be a smoother solution for what you’re trying to do! Here’s how it works:
You can add price based on dimension with your own calculation, and it will appear right on your product page.
This app is simple to set up, and I hope you check it out. Let me know or reach out to Easify if you need any support!
Hey,
Let me share one of the many templates from your Calculator app. You can certainly customize the templates or generate the entire thing with AI. Just feel free to play around and see if that dynamic calculator can fit your needs.

Great question. You’re totally right: relying on an embedded Excel sheet can be clunky and slow for customers, especially with complex size-based calculations.
I’d recommend checking out Shopify PC Price Calculator by Formula app instead.
