I will develop a widget for calculating vehicle leasing costs

I design and develop turnkey leasing cost calculation widgets for commercial vehicles — for trucks, minibuses, special equipment and other commercial transport. A leasing company website visitor specifies the transport type, cost, lease term and down payment amount, and the widget immediately shows the approximate monthly payment. This saves the customer from waiting for a lengthy manager calculation and increases inquiry conversion on the site.

I handle both the calculation logic and the widget presentation. The formula accounts for residual value, interest rates by transport category and down payment size, so the figure on screen comes close to a real commercial offer, not a rough estimate. I adapt the appearance to match your site's design, the layout works correctly on mobile devices, and the widget doesn't slow down page loading. If desired, I add a contact capture form right after calculation so an interested visitor can submit an inquiry without leaving the page.

Before delivery I verify calculations across different transport categories and boundary values — minimum and maximum lease terms, different down payment percentages, zero and incorrect input values. I provide source code, brief documentation and remain available for improvements after launch.

What is included in the work:
— calculation logic for trucks, minibuses and special equipment;
— adaptive layout matching site design;
— configurable rates, terms and down payment ranges;
— optional inquiry capture form;
— source code and documentation.
