About Rental Income Projection Calculator

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.

Formulas

Income = monthly rent x (1 + escalation)^(n-1) x occupied months

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Rental Income Projection figure worked out?

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.

Is a fixed escalation realistic?

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.

What values do I need to enter?

This calculator takes 4 inputs: Current monthly rent, Annual escalation, Projection period, Vacant months per year. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
