Rent Shortfall Calculator
Calculate the rent shortfall or surplus by comparing contractual rent with what tenants can afford based on income. Uses the 2.5x affordability ratio (annual income should be 2.5x the annual rent).
Property owners and landlords often depend on rental income to cover mortgages, maintenance, and daily expenses. But what happens when the rent you receive is less than what you need? That gap is called a rent shortfall.
The Rent Shortfall Calculator helps you quickly figure out the difference between your expected rental income and your actual or required income, so you can plan ahead and avoid financial strain.
🔎 What is a Rent Shortfall?
A rent shortfall occurs when:
- Actual rent collected is less than expected.
- Rent doesn’t cover mortgage, utilities, or expenses.
- Tenants pay below-market rates.
- Vacancies or late payments reduce rental cash flow.
This calculator is a must-have for landlords, property investors, and tenants budgeting rental costs.
