Related verb
The adjective 'rentabel' (profitable/worthwhile) is closely connected with the reflexive verb 'sich rentieren' (to pay off / to be worthwhile). If something 'sich rentiert' (pays off), then it is 'rentabel' (profitable/worthwhile).

rentabel vs interessant
interesting
'interessant' and 'rentabel' can both mean that something is worthwhile. The difference is in the focus. 'rentabel' is used especially when something brings profit or makes economic sense. It sounds factual and fits well with companies, projects, or investments. 'interessant' is broader and a little more cautious: an offer can be 'interessant' because it has advantages, but it does not necessarily guarantee a profit. If you are clearly talking about money and profit, 'rentabel' is more precise.
rentabel
Für die kleine Firma war der Online-Verkauf nach einem Jahr rentabel.
For the small company, online sales became profitable after a year.
interessant
Das neue Jobangebot ist interessant, weil die Arbeitszeiten besser sind.
The new job offer is attractive because the working hours are better.
