Mortgage Calculator

Providing home buyers an easy way to estimate their monthly payments.


Based on several surveys and user feedback sessions, there was an opportunity to enhance the Mortgage Calculator on the Coldwell Banker page. I conducted a competitive and heuristic analysis to identify areas of improvement. Our KPIs included the number of interactions and post-launch surveys.

Initial Launch

We developed a rough prototype to test with users on HotJar and had several useful responses. There was a priority on speedy delivery in order to get quick feedback. The initial prototype was finished in two sprints.

Initial User Testing


Knowing that 61% of our page views are on mobile devices, I needed to design a solution that was responsive to all device types. I wireframed a few solutions that would account for the feedback provided from the survey, including optimized number sliders and live mortgage rates.
