| Well, the linked calculator seems bogus (at least for me here in Germany). It assumes that the income is AFTER taxes. Let put some numbers in: Given I am a programmer in Germany And I earn 4000€ (above avg.) before taxes [1] That means I will have around 29000€ after taxes and other social charges [2] Now if I only spend the bare minimum (9000€) [3], I can save 20000€ per year. Now I am able to retire after 9.5 Years according to calculator. This seems right, as if I still want to live off 9000€, but guess what: The living costs (even if I do stay single, live in the same small flat and never do any vacation) rise with the years. Now you could argue, that a saving rate of 68% might be too much, but even if you decrease the saving to 10000€ per year, you are working around 25.2 years which is plenty of time to burn out...

The calculation in the link takes into account inflation, so that (massive) aspect of increased expenses is included in the prediction.
Edit - If indeed you are planning to increase your living expenses after retiring (bigger living quarters, more expensive travel, etc) that would certainly lengthen the amount of time of work needed to achieve financial independence.
