Karl's Mortgage Calculator

Great app that really helps you understand your mortgage. Where I'm from its common to allow an annual payment of up to 5% of the then-principal of a fixed mortgage to be repaid. Be good to have this as an option in the app.

I used to love this app but now it doesn’t seem to calculate the extra payment no matter how I input it

This calculator is invaluable for comparing different scenarios and payment schedules for any variety of mortgage products. The extra payments feature and ability to add in taxes is super useful as well. I can’t speak highly enough about how easy to use it is as well. Strongly recommend for any financial planning for a loan or mortgage product

I've been using this app for years. To me, it's a perfect as I could hope for. Simple interface but still plenty of options. You won't find a better mortgage calculator.

App was working fine at first but now I can’t even calculate a normal payment. It keeps defaulting to 100 years and it says to change to payment radio button. It’s getting annoying so I stopped using. Please fix

I was excited about it have 365 interest compound selection, I don’t have to open my excel worksheet. But it won’t calculate as 365. I think it’s not working.

First, thank you to the developer of this calculator. Everyone has been coming to me for their mortgage advice because of this simple tool! It’s still getting 5 stars however, now maybe with the newer iPhones, I can’t see the entire table to the right. It seems to be cutoff. I can still get the first few numbers ie: “400,” instead of “400,000.00”.

I would give 5 stars if it had updated the FHA MI rules. It’s running off the old numbers. But I use this app all the time! Love it. The ability to add in a temp buy down scenario would be an awesome add too.

I just want to let Karl and the world know that I use this app ALL THE TIME. It works so well when I am calculating not only mortgages and commercial loans but also auto loans or really anything. I appreciate you building this!
