The first calculator is designed to compare a fixed rate and a variable rate over a 5 year term. You have the option to predict rate changes throughout the term of the variable rate mortgage and it will give you the equivalent fixed rate with these changes. It will also tell you which mortgage allows you to come out ahead and by how much.
In order to make this an accurate comparison the monthly payment will be the same for both rates, based on the fixed rate. This eliminates any time value of money issues.
This has been a my hobby site for a few years now but unfortunately I have not have time to continue to improve it. My hosting and domain name are expiring in June 2019 and if I do not get enough donations to pay for each I will not be renewing and the calculators on this page will no longer be available. If you find value in these calculators and would like this page to remain please consider donating by clicking the Donate Button on the right hand side of each page. Thank you for your support.
