Actually the link you provided in your question, gives you all the information you need.
The fund has an load fee "Ausgabeaufschlag" of 3,75% and a TER (Total Expense Ratio) of 1,43% per annum.
A somewhat similiar ETF, to compare your fund with, is iShares Dow Jones Global Titans 50 UCITS ETF (ISIN DE0006289382), which has a TER of 0,51% and no load fee.
In the end this means, your fund has to first outperform the ETF to offset the initial load of 3,75% of your investment once and additionally has to outperform the ETF by another 0,92% (1,43% − 0,51% TER) every year.
We have to keep in mind that past performance is no indicator of future performance, but if we look at the last 5 years this hasn't happened. Again using the fund comparison function of your link, we get the following returns:
Deka-GlobalChampions iShares Global Titans 50
1 year 11,91% 14,60%
3 year 39,60% 39,27%
5 year 71,95% 76,65%
You would have been slightly better off with the ETF given this 5 year timespan.
So will this specific ETF outperform your fund in the future?
We don't know, but given the load fee and higher TER, it is likely, that the ETF will outperform the active fund slightly every year and given a long investment horizont, this small difference in performance, may compound to a meaningfull difference over an investment life of 25 years or longer.
Does this mean that every active fund is bad?
No, there will always be some managed funds that outperform their ETF counterpart, but general wisdom in the moment is that managed funds (especially those with a high TER and a high load fee) have a hard time to match the performance of low cost ETFs.
And as you have no way to know which active fund will be one of the few who outperform their ETF counterpart, you'll in most cases be better off choosing the ETF from the start, instead of trying to pick the right active fund (which is akin to trying to guess the right numbers in tomorrows lottery).
