This little project has a simple calculator with two repayment options and uses the same code base as this Czech version. When you click to apply you have a choice about which one you want to use:
This is set up for a client so their interest rates may not be the same as yours. But it’s all easily editable of you want something different.
If you want a version like this please contact me.
Note that these plugins are not free. The cost depends on the complexity of the plugin and what changes you need doing.
