Family budget planner

A month ago I bought an apartment by taking a mortgage loan. From now on I will have to plan my finances more precisely to pay my mortgage on time. I decided to automate the planning process.
The idea was to make a budget plan for the years ahead once, then regularly enter the actual cache flow and track the difference between the planned and real income and expenses. As result I've created the calculator below. It can take considerable time to create a budget plan and enter your transactions, so you can evaluate the calculator performance using:

The calculator is not finished at the moment. Now it only reflects my initial vision of the family budget problem.
If you, like me, are interested in convenient and free software for managing the family budget, please write your ideas in the comments, I will take them into account in future updates of the calculator.
