User Reviews

Users highly value Karl's Mortgage Calculator Pro for its accuracy, powerful features including extra payment options, and ability to match real mortgage data. Many appreciate its detailed summaries and support for various mortgage types. Users commonly upgraded to pro to support the developer. However, some note usability issues like a dated UI, occasional buggy behavior that freezes inputs, missing features for miscellaneous fees, and errors in recalculating balances when interest rates change after extra payments.

Pros

Very powerful and accurate mortgage calculator that matches real bank figures.
Supports multiple mortgage types, including adjustable rate mortgages and country-specific options.
Allows for extra payments and shows impact on mortgage interest and payoff time.
User-friendly with useful summaries, tables, and charts that aid understanding and presentations.
Reliable and useful enough that many users upgraded from free to pro to support developer.

Cons

User interface is not highly praised and could be improved.
The app sometimes becomes unusable due to bugs, such as randomly entering incorrect figures and preventing changes or clearing fields.
Lacks a field for miscellaneous fees or separate fees when points are used, limiting amortization accuracy.
Incorrect recalculations when interest rates change after extra payments, causing totals to remain the same erroneously.

Recent reviews

Works very well predicting my mortgage payments and breaking down the total cost. Seems to have lots of functionality for arm mortgages as well

I never write reviews but made an exception here and purchased the pro version to support the developer. This is an incredibly powerful mortgage calculator and does exactly what you need without any of the nonsense. I'm not in love with the UI but that can be overlooked by how useful it is.
