Can anyone recommend a calculator plugin for product cost per use?

Topic summary

A merchant is seeking a Shopify app that allows customers to calculate cost-per-use for products. The desired functionality: customers input how many times per week they’ll use an item, and the calculator displays the annual cost per use to demonstrate value and make products more attractive.

Recommendations provided:

  • Appstle Subscriptions: Suggested by a user who needed similar functionality with subscription conversion. Features a ‘build a box’ option, though it may include more features than needed for basic cost-per-use calculation.

  • Weario: Recommended as a purpose-built solution for this exact use case. Key features include:

    • Customer input for usage frequency (weekly/monthly/yearly)
    • Automatic cost-per-use calculations
    • Adjustable sliders for personalized estimates
    • Works on product, collection, and cart pages
    • No coding required (app embed blocks)
    • 14-day free trial available

The discussion remains open as the original poster is evaluating the suggestions.

Hi, we are currently building a Shopify store for various products. We would like to include a calculator where the customer can enter a number of how many times they plan to use the item per week. The calculator should then work out how much the product costs per “use” for a year. Is there a plugin or app for this? This should help make the product more attractive when customers see that the per use price is relatively low

Thank you in advance for your help.

I had to create a similar feature and tested quite a few of these apps out. None would actually work for me because I had to convert the customer into a subscription model at the end of her selection.

The best on for me was this: https://apps.shopify.com/subscriptions-by-appstle

It has a ‘build a box’ feature as well. Maybe worth a look for you.

Let me know if I can be of any further help

Thanks for your quick response and help, I will have a look at this plugin.

Hi there!

This is exactly what our app Weario was built for! Customers can input how often they’ll use a product and it automatically calculates the cost per use over time.

Here’s how it works for your exact use case:

  • Customers can input how many times they’ll use an item per week/month/year
  • Automatically calculates cost per use (daily, weekly, or however you set it up)
  • Shows results like “$60 jacket = $0.16 per wear over a year”
  • Customers can adjust their estimates with sliders for personalized calculations

You’re absolutely right that showing the low per-use price makes products more attractive! We’ve seen merchants increase conversions because customers suddenly see value over time instead of just the upfront cost.

The app works on product, collection, and cart pages and integrates via app embed blocks so no coding required. Has a 14-day free trial if you want to test it out: https://apps.shopify.com/weario

Hope this helps solve exactly what you’re looking for!

Hi,

In case you haven’t seen Elfsight Calculator app, let me share a sample screenshot of what you can build. We have numerous templates for your scenarios, many price and cost calculators among them. All are compatible with Shopify.

Also, there is an AI feature to generate a calculator form based on your description.
