Investment Calculator of 800+
We all want to give our children the best financial start in life when they become adults. One way to do this is to invest money for them while they are still young. In Poland, the government gives parents 800+ PLN per month for every child.
Calculator has some assumptions and default values that you can change and play with it.
In the 8 years of 800+ program there was at one revalue of 500+ PLN to 800+ PLN. There maybe in the future another valorization of this money so I gave option to change the amount of money that you would like to invest.
Also I’ve added ability to change the interest rate on savings accounts as every banks has different offerings. For bonds I’ve took 12 years bonds PLN from Poland which have 6.8% interest rate in first year.
If you enable adjust for inflation option, it will show real value of money based on starting point adjusted. It’s based on last 18 years historically mainly:
