How This Calculator Works

Potential gross income is what you'd collect if every unit were rented for the full year at full rent — the baseline vacancy loss is measured against.

Vacancy loss converts your vacant days into a dollar figure using a daily rent rate, then compares that to potential gross income to get a vacancy rate percentage — a useful metric to track over time and compare against local market averages.

Lowering vacancy days even modestly has an outsized effect on annual income, since every day a unit sits empty is 100% lost revenue for that day rather than a reduced amount — turning around a unit a week faster on average can meaningfully change your bottom line across a full year.
