Karl's Mortgage Calculator Positive Reviews

Easy to useThis app is simple enough to understand while giving you just the right amount of detail without overwhelming its user. I only wish that it could operate in landscape view to accommodate iPad technology. But that’s just a minor critique. Overall great app!👍🏾.Kj246Version: 2.2

This is superior!I wanted to determine what the short, mid and long term financial benefits would be in refinancing our current mortgage now that interest rates have dropped. I wanted detailed comparisons, and some key questions answered, not just a semi-useless summary. I tried several online calculators... very awkward to get the level of detail needed. Irritating ads. Needed pencil and paper - to answer some key questions - awkward. I could have done it manually on my business calculator sitting idle in the kitchen draw.... big pain in the neck to get the level of detail needed in usable form. Karl’s calculator was fantastically easy to use, user friendly, fast, and lays out all the amortization details on an easy to play with slider tool. The amortization tables, with loan balances, interest paid, etc. etc., charts, graphs, summary, and more are all there and intuitive to use. So, I entered the variables for my current mortgage and wallowed within the results. Did the same for other scenarios. I emailed the detailed reports to myself, compared the .csv spreadsheets (all on my IPad). Don’t bother to look elsewhere for a mortgage calculator. Even if your needs are totally basic, you can’t beat this one..Gt12fyi3Version: 2.2

The best mortgage calculator ever!!!I own a handful of properties and I’m always looking for ways to tweak my payments as rent goes up or as I come in to more income so that I can shorten my payoff dates. There are plenty of mortgage calculator apps or online calculators out there, but I always find some thing that they’re lacking or that’s annoying about their use. But Karl’s calculator is just about perfect. I love that I can easily create new scenarios and that they automatically save and that I can email them when I’m done and the recipient of the email does not need the app in order to see the summary. Simply click on the attachment and they have a tidy summary of the scenario that I’ve run. Like I said, perfect!.Props4chickyVersion: 2.2

This app is the truth!I am buying my first home and wanted to be able to play with some scenarios after speaking with my lender. I was able to arrive at the same numbers we’d discussed and then play with them by adjusting different amounts. You can include PMI, based on your credit, and other relevant factors - or not. I feel some empowered! I can’t wait until my next conversation with the lender. She won’t know what hit her! Thank you so much for this invaluable tool..NiccilynnwilliamsVersion: 2.2

Love itMy husband and I owner finance land. Our customers are always wanting to know notes, down pmt. and how the interest thing will work.... so we calculate it and snap them a picture of it and it answers all their questions. So east to use. Looked at several other and they didn’t always work correct and eventually want to charge you huge fee to do the same thing this app does for free. Thank you Karl... wherever you are..Sandy1486Version: 2.2

Incredible AND easyThis 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.Jay19671Version: 2.5.2

Simple yet powerful! An elegant app.This app has it all! Just get this and have the best mortgage calculator there is for a modest fee. I’ve been using it since inception and have saved lots of money by seeing the impact of extra payments on my principle balance. Get this app, you won’t be disappointed..CatendahatVersion: 2.2

Long time userI'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..Dragondrop1Version: 2.5.2

Great app! I need more slots for paymentsI’m trying to calculate how quickly I can pay off my house, but I ran out of slots for extra payments. There are only 30 as far as I can tell. Income varies month to month so it’s nice to have my payments I’ve already made in the calculator as well as plans for future payments..Google photo loverVersion: 2.2

So motivating!I paid off my mortgage in 4.5 years and this app has been so motivating for me all along the way. I really like all the visuals and also the option to add so many different extra payments one-time or recurring for a period. Thank you, Karl!!!.Now a TexanVersion: 2.2

I love this appI 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!.Network GodVersion: 2.2

Great appAwesome calculator to run different scenarios of increasing monthly payments vs. refinancing at the lower rates that are now. Wish I knew about it a few years ago. Definitely a robust app, I’m glad the developer took the time to do it and offer it for free (as of now)..GogosarVersion: 2.2

It's awesomeAlways loved the online version, the app is even better. All the features you'd want. Love the ability to see how potential extra principal payments effect loan timetable and how much interest would be saved..FixandflyVersion: 2.2

HelpI can’t figure out why when I populate the purchase amount, the loan amount auto populates to the same number. Even if I start with the loan amount the purchase price will change to that number. How do I make it so I can have separate values for each again?.TmineyVersion: 2.2

Love this app. I suggestMy broker told me of this app. Great app, suggestions to make better: when a loan is emailed it should include the name the loan was saved as. Also it'd be great if I could share the loan saved in the calculator with others who want to tweak the loan values as opposed to just emailing an HTML file..BruceS2Version: 2.2

10 years using it?I think I’ve been using this for a decade now. Awesome for letting you the affects of paying extra on your mortgage. Just wish it had iCloud or Dropbox sync.AsisonlascosasVersion: 2.2

Amazing!!!This is a clearly a thorough thought out and beautifully executed app, all around. I just wish I could adjust the property tax values like I can adjust the interest rate. Not a fan of the name, but if I wrote this app I’d probably ‘pull a TRUMP’ as well..Mr.InggoVersion: 2.2

365 and 360 Interest CompoundI 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..BoMTG555Version: 2.5.2

The BestI have reviewed several Real Estate mortgage calculators. I have found Karl's to be the best so far. Easy to use and allows you to add insurance and taxes to get as close as possible to a mortgage payment as possible..Two1253Version: 2.1

Love this appI 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..JensbranVersion: 2.2

Extra paymentsLove this app!!! Just please add more extra payment boxes!!! I only have one box left :(. I always have a different amount that I pay for my principal..:))))12Version: 2.2

Simple, powerful, everything is thereFINALLY FOUND ONE! This mortgage calculator is simple to use, provides a wealth of data that you can use or ignore the tab, and provides options to put in HOA fees, extra principal, etc. It is ad supported, but the ads are neither obnoxious nor do they slow down the functionality of the app! Deleting all other crappy apps and installing this on my phones and IPad. 5 stars!.Uncle Eddie99Version: 2.2

Great calculator but missing some featuresI've been using the web version Karl's calculator since many many years ago and love it. Unfortunately the iOS port of it is a very basic port of it and could use a cleaner look and feel. The biggest missing feature for me it's having the ability to have multiple saved calculations as I often compare scenarios. I'd also like to see a paid option that removes ads. Will definitely update review to 5 stars if the above are added. *Update* I changed rating from 3 to 4 because I found that there's a way to save mortgage setting. Not the most intuitive location but it works.Foosball_pVersion: 2.0

I’m 9 years inI’m 9 years into my loan and it only works for new loans. I can’t adjust the payment amount to reflect my payment and the payoff day before implementing an early payoff isn’t correct. My payoff is 2036 but the app says it’s 2041. Very confusing to use.MisteriosamistyVersion: 2.2

Works as describedDoes everything I need it to do. I really like the email feature!.Saber5130Version: 2.2

Very goodThe best calculator out there..Zee75Version: 2.1

Best Mortgage CalculatorI had this calculator for years on my Samsung and was waiting for it to come available on IPhone! This is by far the easiest, most accurate, most versatile calculator available for mortgage information. Put in property values and set your % down based on loans your looking at and bam! It puts up the down needed, and has adjustments for APR rates as well as many others. Your monthly total pops up and it's dead on. You can add extra monthly payments, annually, semi annual, taxes, rents collected, everything. But it's simple and easy! Soooo easy! Love Karl's Mortgage Calculator! Doing a happy dance now that it's available on IPhone.907investorVersion: 1.0

Just PerfectBetter than any other mortgage calculator app. Have tried Bankrate, Zillow, Quicken etc. This one gives you access to all the info you need in simple readable language. If the next version lets you email your data to input into excel it will be even more perfect!.YioryoVersion: 1.0

Finally!!!Finally!!! A mortgage app with the ability to calculate prepayments of different amounts at different times. After downloading and deleting over 30 "apps" this one is a keeper. The only one I'd ever need! Highly recommended!.FWS71Version: 2.0

Karl's Mortgage Calculator Negative Reviews

Doesn’t workI really like the web site calculator, but this app just doesn’t work properly. Every time I change a value in one field it arbitrarily changes values in another. For example, if I set the initial principal then set the interest rate, it will change the term length. If I then change the interest rate it will change the principal. Sometimes I can’t change a value at all. Very confusing and frustrating as it makes the app useless..A35DriverVersion: 2.2

Loved it at first but not no moreApp 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.Iowa5770Version: 2.5.2

BugApp was working great, until it wasn’t. Had to delete and re-download. And now it’s not working again. It quit letting me input the interest rate or the term length. Keeps saying to hit payment radio button, which I cannot find..MarkwhitelawVersion: 2.2

Steals your keyboard contentsAbsolutely no reason that this simple app should be reading, copying & pasting the contents of your keyboard. Notably the app hasn’t been updated subsequent to Apple’s App Store privacy transparency changes. Stop invading our privacy and stealing the contents of our keyboards. UNINSTALLED..PatFin927Version: 2.2

Program never loads on my iphone 7 plusI tried to run this app and it never loaded it just hangs on a blank screen. I tried reinstalling with the same problem.Chadw007Version: 2.2

FrustratingDeleted from my phone because it was too frustrating to use. Trying to enter a known amount for a loan and no matter what I do it insists on reverse calculation, and changes the loan amount..ZztrmVersion: 2.2
