Why Has My Finance Calculator Stopped Working?

Troubleshooting steps to follow if your website's interactive finance calculator is missing, blank, or displaying errors.

Your website's finance calculator is one of the most important tools on your digital showroom, allowing customers to explore quotes, adjust deposits, and check their eligibility. If it stops working, it can disrupt your digital leads and customer journeys.

In most cases, a calculator issue is caused by a simple detail, such as an error in a vehicle's data, a recent change to your website's template, or a minor setting in your finance configuration.

This troubleshooting guide will walk you through the most common checks to get your calculator back up and running.

Step 1: Is it just one vehicle, or is it widespread?

Narrowing down the scope of the problem is the quickest way to find the root cause:

  • One vehicle: If the calculator works fine on most of your website but fails on a specific vehicle, the issue is almost certainly a data error on that particular vehicle listing (such as missing pricing, a typo in the mileage, or an invalid registration date).
  • All vehicles: If the calculator is missing or broken across your entire website, this points to a wider website integration error, a recent website template update, or a central configuration setting on your iVendi account.

Step 2: Check the vehicle’s data

If you've identified that only one or a few vehicles are affected, double-check the listing details inside your DMS (Dealer Management System) or stock management system. Make sure the following fields are correct and complete:

  • Selling Price: Is the cash price entered correctly? (make sure it isn't set to £0 or left blank).
  • Mileage: Is the mileage realistic? Watch out for accidental extra zeros (e.g. entering "500000" instead of "50000") which can push the vehicle outside of all lender limits.
  • Vehicle Registration Number: Is the the vehicle's registration number entered correctly?
  • Registration Date: Is the vehicle's first registration date present and accurate?
  • Condition: Is the vehicle marked correctly as New or Used?
  • Vehicle Class: Is it categorised correctly as a Car, LCV (van), or Bike?

How to fix it: If you spot an error, correct it in your stock management system. If your stock is supplied to iVendi via an automated feed, the calculator will resume working once the updated feed has processed.

Step 3: Observe how the calculator is failing

Take a close look at what happens on the page where the calculator should be. This will help you identify the type of issue:

  1. The calculator is completely missing: There is a blank space where the calculator usually sits. This often happens if your website provider has recently updated your page templates or modified the site's underlying code, which may have accidentally removed or broken the iVendi embed code.
  2. The calculator box is visible but empty/spinning: The widget frame loads, but it remains blank or shows a loading spinner indefinitely. This usually indicates a temporary network block or a cached data mismatch.
  3. It loads but says "Finance Unavailable" or "Quotes Not Found": The calculator works, but it won't display any monthly payments. This means the vehicle's details (such as age, mileage, or price) fall outside the strict parameters configured for your active finance products.

Step 4: Refresh and retest in a clean window

Before escalating the issue, let's make sure you aren't viewing an older, cached version of your webpage:

  1. Hard Refresh: Force your browser to load the newest version of the page (Ctrl + F5 on Windows, or Cmd + Shift + R on Mac).
  2. Incognito Mode: Open a new private/incognito window in your browser and search for the affected vehicle. This bypasses any saved cookies or local browser cache.
  3. Try another device: Load the vehicle's page on your mobile phone or a different web browser (Chrome, Edge, Safari) to see if it works there.

Still not loading? Let’s get it fixed!

If you have verified the vehicle's information and refreshed your browser, but the calculator is still not working, our Product Support team is ready to investigate.

Please email Support@iVendi.com with the following details:

  • Dealership Name
  • The URL (link) of the affected vehicle page on your website
  • Affected Vehicle Registration (VRM)
  • Scope of the issue: Does it affect one, several, or all of your vehicles?
  • What you are seeing: (e.g., "The calculator box is completely blank," or "It loads but displays an error message")
  • Recent changes: Have you recently updated your website, switched website providers, or changed your stock feed?
  • Screenshots: If you can take a quick screenshot of the issue, that's incredibly helpful!

With this information, we will check your data feed, inspect your widget integration, and verify your finance configuration to get your calculator back on track.
