Royal Bank of Canada is a Canada-based bank providing various banking services to both individuals and businesses. The web site has a “Mortgage payment calculator” tool, which allows home buyers to calculate the regular payments for the mortgage loan, and a “Mortgage
affordability calculator” tool for home buyers to calculate how much home can they afford without affecting their life.

I also evaluated the “Mortgage affordability calculator” tool using the same Cognitive Walkthrough technique. Here is the evaluation report.
