About our budget calculator
How are the results calculated?
The calculator subtracts the sum of all expenses from the household income to determine your balance. For the 50-30-20 check, the expenses are assigned to the three categories and its share of the total expenses is calculated.
How are the three categories defined?
To the necessary expenses we count the expenses from 'housing', 'insurances' and 'food & drugstore'.
To leisure spending we count spending from 'mobility', 'shopping', 'subscriptions', 'going out', 'experiences', 'donations' and 'other'.
Everything in the 'Saving' section we count to the 'Saving' category.
What do I do with annual expenses?
If you can, calculate expenses you make once a year down to the month. However, it is not a problem if you do not enter annual expenses here. This way you still get a good overview of your regular expenses.
