The infinitive ‘calculer’ is not used for a command; you need the imperative ‘calcule’.
Calcule ton revenus mensuels.
‘Revenus’ is plural; the adjective ‘mensuel’ would then need to be plural ‘mensuels’, which changes the meaning.

Mixing formal ‘votre’ with the informal imperative creates a register clash.

Cultural Tip
In informal conversation among peers, the ‘tu’ form (Calcule ton…) is natural. In a professional or formal setting you would switch to the ‘vous’ form: ‘Calculez votre revenu mensuel.’ Also, French speakers often distinguish between ‘revenu brut’ (gross) and ‘revenu net’ (net); be clear which figure you need.
