Work out rental income projection instantly with clear inputs, formula shown and shareable results.
Rental projection compounds the current rent by the annual escalation and multiplies by the months actually let. Allowing even half a vacant month a year removes about four percent of gross income, which is a larger effect than most escalation clauses deliver in their first year.

Sum across the projection period
Income = monthly rent x (1 + escalation)^(n-1) x occupied months. Rental projection compounds the current rent by the annual escalation and multiplies by the months actually let.
It reflects what the lease says, not what the market does. On renewal the rent resets to market, which can be above or below the escalated figure.
