Do you know how much you need to save to stay where you are?

That would be good. But I am heating the house with gas. And the price of the gas can change a lot. The price of the electricity can also change a lot. And the buying power of the money can also change a lot. Even in a single month. For example the consumer prices increased by 7.40% in 2021 december. This value is very similar to the USA, where the consumer prices increased by 7%.
