Entering the percentage of fixed costs

We have set the percentage of those classic costs (electricity, fire insurance, etc.) within Dexxter at 20% for professional purposes as a kind of standard value. This is mainly because we also want to protect student entrepreneurs and secondary occupations to some extent, as with this 20% limit, you will not be miles from reality as a student entrepreneur or secondary occupation.But that percentage can of course be adjusted to your own reality. As you rightly point out, if your professional space (the space of your home office, for example) is actually only 17%, you can simply adjust that percentage from 20% (the standard value in Dexxter) to 17%.

You can do this in the cost categories screen. Next to each cost category, you will see a pencil icon (on the far right of the cost categories module). Click on it and you can easily adjust the percentage to 17%.

To give a very concrete example. Suppose you have an invoice in the future from 100 euro (the total amount stated on the invoice). When you enter this in Dexxter, you can simply enter 100 euros under amounts (step 3 when entering expenses). In the next step (step 4, cost categories), the restriction is applied based on the professional percentage.

The 17% restriction is more than sufficient if that percentage is an accurate estimate of your professional use. In other words, if you take 17% from only 20%, you will end up with a restriction that is far too high, leaving you with hardly anything to enter in your accounts as expenses.
