Karl's Mortgage Calculator Pro

About this app

This is the Pro version of Karl's Mortgage Calculator. The only change from the free version is that the adverts have been removed.

Calculate mortgage payments given principal, interest and term. Reverse calculate any one variable given the other three.

Enter a down payment amount or percentage and let the calculator show how large a mortgage you require.

See how the monthly payment changes when you factor in additional monthly or annual loan costs such as PMI, HOA, taxes and insurance.

The calculator supports Fixed and Adjustable Rate Mortgages (ARM) loans with up to five changes in interest rates. Interest-only mortgages loans are also supported.

You can pay off your mortgage early with extra payments. Add one-off, monthly and annual extra payments. Choose up to six additional extra payment amounts and payment periods and the calculator will show how much money you can save on the loan.

Choose from weekly to annual loan payments and adjust the compounding period from daily through annual periods. The calculator supports Canadian mortgages along with UK annual rest mortgages.

Multiple rounding options on loan calculations are also available. Choose between no rounding, round half up, half down, to even, to ceiling and to floor.

The calculator also supports the input and display of multiple currencies.

Ratings and reviews

App just became unusable. While working on my own mortgage calculations, the app suddenly quit allowing me to make ANY changes and started randomly entering figures that make ZERO sense. Cannot clear any fields. Cannot start over. Cannot start with a clean slate unless I uninstall the app???

Been using the free version for a while. Upgraded to pro to support the Dev. It's the only app I've found that allows extra payments, shows Int. saved over mort term & projected length of time to pay off. It closely aligns with my actual mort bal in my banking app. No slider bars (a huge Yay!) Manual inputs only. Many useful features. I've tried many others only to discard them immediately. None even come close to matching the features and functionality of this one. Best Mort/Loan app yet 👌

I don't write reviews, I had to for this app. There had to be a ton of work put into this calculator, it matches my bank perfectly and being able to select mortgage types for each country should make everyone who buys this very happy. I bought it primarily to see the impact of extra payments to pay down mortgage early. Thanks for this app, it was exactly what I needed.
