In the past few months, we have covered plenty of useful plugins and extensions for finance focused websites. Loan Comparison is also worth a look. It is a responsive plugin that lets you offer loan comparisons on your website with a professional look.
The plugin is highly customizatable. It lets you set the max, min, initial and step values on the sliders and use any currency. You can set interest rates and change labels. The premium version offers even more features. For instance, you can upload data with a CSV file and display up to 10 comparison tables.
