Testing more than one loss assumption can show how sensitive property income is before expense underwriting begins.

Estimate effective gross income from gross potential rent minus vacancy and collection loss.
Why this page exists
Property income is easier to evaluate when vacancy and collection loss are pulled out of gross potential rent instead of being left as a vague risk factor. This calculator helps visitors estimate effective gross income from annual gross potential rent and a vacancy or collection-loss assumption so the result can be reviewed before operating expenses are applied.

Calculator
Estimate effective gross income from annual gross potential rent and vacancy or collection loss.
Result
Estimated effective gross income from annual gross potential rent minus vacancy and collection loss.
This is a simple property-income estimate only. It shows income after vacancy or collection loss, but before operating expenses, financing, and taxes.
Planning note
Last updated April 17, 2026. Use this tool to compare scenarios and plan ahead, then confirm important details with the lender, employer, insurer, contractor, or other qualified provider involved in the final decision.
How it works
Enter annual gross potential rent and choose whether vacancy and collection loss should be entered as a dollar amount or a percentage.
The calculator converts the loss assumption into a dollar amount when needed and subtracts it from gross potential rent.
It shows the effective gross income result together with the gross rent and loss inputs used in the estimate.
Understanding your result
This is a simple property-income estimate only. It helps show what income may remain after vacancy or collection loss, but before operating expenses, financing, reserves, and taxes.

Example scenarios help turn a quick estimate into a more useful comparison or planning step.
Testing more than one loss assumption can show how sensitive property income is before expense underwriting begins.
A percentage loss looks more practical once it is shown as a dollar reduction to annual income.
Effective gross income often makes more sense when reviewed beside operating expenses, reserves, and rental cash-flow tools.
When to use it
Use this when you want to see how much income may remain after vacancy and collection loss, before operating expenses are applied.
It is especially useful when comparing several vacancy assumptions during property screening or quick underwriting.
Assumptions and limitations
The estimate assumes the gross potential rent and loss assumption refer to the same property and the same annual time frame.
It does not model expenses, management fees, reserves, financing, taxes, or one-time income adjustments.
Common mistakes
Treating effective gross income as profit can be misleading because expenses and reserves have not been removed yet.
Using a vacancy or loss estimate that is inconsistent with the property type or market can make the EGI figure look cleaner than reality.
Practical tips
Run more than one loss assumption if you want to see how sensitive the property looks under tighter collection or occupancy conditions.
Pair the result with expense and cash-flow tools so the property is reviewed beyond the top-line income step.
Worked example
A worked example shows how the estimate behaves when the inputs resemble a real planning decision.
An investor expects $180,000 of annual gross potential rent and wants to test an 8% vacancy and collection loss assumption.
1. Enter annual gross potential rent.
2. Convert the loss rate into a dollar amount or enter a direct loss amount.
3. Subtract the loss from gross potential rent to estimate effective gross income.
Takeaway: The result gives a cleaner pre-expense income number than gross potential rent alone.
FAQ
The calculator subtracts vacancy and collection loss from annual gross potential rent to estimate effective gross income.
Because effective gross income is often used as an intermediate step between top-line rent potential and deeper expense or cash-flow analysis.
No. This calculator stops before operating expenses, so it is not the same as net operating income.
