I have a deep and abiding annoyance with online loan calculators.

I blame them for being:

Clumsy
Restricted
Self-Interested

So when I found that Open/Libre Office has good support for calculating repayments it has come as a relief.

I will now be able generate my own payment guestimations without relying on a annoying sliding widget or a site that is preconfigured according to someone elses preferences.
