Simple, uncluttered


Simple. The only major inputs are loan amount, loan duration, interest rate, and extra payments.

Gives monthly payment and amortization schedule.

Initially, I thought that I wasn’t getting much for my money. Then I realized that I was using it for every real estate deal that I analyzed. So, it has been a very good value.

A simple suggestion would be to add purchase price and down payment %, which would be one frequent calculation that I do to get to the loan amount input. I can do that in my head but it is one more thing that I could mess up.

Appreciate the communication by the developer.

Developer Response

Edit: Thanks for the re-review! Glad it’s working for you. Great suggestion. I’ll see what I can do!

Thanks for the review! Just in case you’re not aware, you’re also able to calculate a weekly or bi-weekly payment. You’ll also see the total mortgage amount (including interest), total interest, and the number of payments made. Not to mention an amortization table and the ability to save and compare mortgages! Stay tuned for more features in the next update!

Best & simplest app I’ve seen


Finally a no-frills, no-advertisement app for calculating mortgages. Worth the price just not I have to see annoying ads.

Just one suggestion: add boxes where I can put in property tax and insurance so I can get a good estimate of what my payment would be.
