additional effort
Additional work, time, or costs required to complete a task beyond what was originally planned or usual.
Durch die unerwarteten Probleme entstand ein erheblicher Mehraufwand an Zeit und Geld.
The unexpected problems created a considerable additional effort in terms of time and money.
The word is a clear compound of 'mehr' (more) and 'der Aufwand' (effort/expense). It literally means 'more effort' and is therefore easy to understand if you know the two parts.
Die Reparatur des alten Dachs bedeutet einen großen Mehraufwand.
Repairing the old roof means a lot of additional effort.
To specify what the additional effort consists of, the preposition 'an' is often used followed by a noun in the dative. Typical phrases are 'ein Mehraufwand an Zeit' (additional time required), 'an Geld' (additional money required), or 'an Personal' (additional staff required).
Das Projekt erfordert einen Mehraufwand an Personal.
The project requires additional staff.
'Mehraufwand' (additional effort) is often used in formal or professional contexts. Typical verbs are 'entstehen' (to arise), 'bedeuten' (to mean), or 'verursachen' (to cause), and typical adjectives are 'erheblich' (considerable) or 'zusätzlich' (additional).
Durch die Planungsfehler ist ein erheblicher Mehraufwand entstanden.
The planning errors created considerable additional effort.
effort / expense
'der Aufwand' and 'der Mehraufwand' both refer to work, time, or costs for a task. 'Aufwand' means the total effort or expense that is needed. 'Mehraufwand' means only the additional effort that goes beyond what is normal or planned. The words can be confused when a task suddenly becomes more difficult. In that case, the whole amount of effort is the 'Aufwand', but the additional part is the 'Mehraufwand'. So 'Mehraufwand' only fits when there is a comparison: more than before, more than usual, or more than planned.
