The word diddordeb is not used for the kind of interest you earn on savings, or pay back when you borrow money. The correct word for that kind of interest is llog.
When the meaning of the English word interest is similar to welfare, as in the phrase the best interests of, the Welsh words lles or budd would usually be used:
Mae gyrru'n ofalus er lles pawb.
Driving carefully is in everyone's best interest.
budd y cenedl
the national interest
