Texas real estate exam property management calculator, from gross rent to net operating income.
Build the operating budget step by step: gross potential rent, vacancy and collection loss, effective gross income, operating expenses, NOI, and the management fee.
Net operating income is effective gross income minus operating expenses. Start with full-occupancy rent, take out vacancy, add other income, then subtract operating expenses. NOI stops there. It does not subtract the mortgage payment or income taxes.
Units times monthly rent times 12. This is the income if every unit is rented all year.
Subtract vacancy and collection loss from gross potential rent to get collected rent.
Add other income such as laundry, parking, or fees to collected rent.
NOI excludes the mortgage payment and income taxes. It stops at operating expenses.
Usually a percent of the rent actually collected, applied after vacancy.
Occupancy and vacancy are complements; together they total 100%.
Build the operating budget from rent to net operating income.
Vacancy and collection loss is subtracted from gross potential rent. Effective gross income is what you actually collect, plus other income.
Net operating income excludes debt service (the mortgage payment) and income taxes. It is effective gross income minus operating expenses only.
A management fee is usually a percent of collected rent, not gross potential rent. Apply it after vacancy unless the question says otherwise.
Net operating income stops at operating expenses. Do not subtract the mortgage payment, depreciation, or income taxes to find NOI. Those come after NOI in cash-flow analysis.

Where do property management questions go wrong?
The arithmetic is simple. The misses come from order of operations and from confusing NOI with cash flow.
Did you start from gross potential rent?
Gross potential rent is full-occupancy income: units times monthly rent times 12. Vacancy comes off this number.
Did you subtract vacancy before adding other income?
Subtract vacancy and collection loss from rent first, then add other income to reach effective gross income.
Are you stopping NOI at operating expenses?
Net operating income excludes debt service and income taxes. Do not subtract the mortgage payment to find NOI.
Is the management fee on collected rent or gross rent?
Most exam setups apply the management fee to collected rent. Read the stem; it occasionally uses gross scheduled rent.
Four property management patterns to know cold.
These cover the steps that cause most misses: gross potential rent, effective gross income, NOI, and the management fee.
10 units at $1,200 per month
Annualize the monthly rent before applying vacancy.
$144,000 GPR, 5% vacancy, $6,000 other income
Subtract vacancy first, then add other income.
$142,800 EGI, $48,000 operating expenses
Do not subtract the mortgage payment to find NOI.
$136,800 collected rent, 8% fee
Apply the fee to collected rent, not gross potential rent.
The property management mistakes that cost easy points.
Operating-budget math rewards a clean order of operations. Run these checkpoints before you trust the number.
Subtracting the mortgage payment
Net operating income excludes debt service. The mortgage payment comes after NOI in cash-flow analysis, not before.
Adding other income before vacancy
Subtract vacancy and collection loss from rent first, then add other income to reach effective gross income.
Applying the fee to gross rent
Management fees are usually a percent of collected rent. Read whether the stem says collected or scheduled rent.
Forgetting to multiply monthly rent by 12
Gross potential rent is an annual figure. Multiply units and monthly rent by 12 before applying percentages.
Putting income tax or depreciation in operating expenses
Operating expenses are the costs to run the property. Income taxes and depreciation are not operating expenses for NOI.
What to study next with property management math.
NOI flows into the income approach to value, and management fees sit beside commission and leasing math. Drill them together.
How do you calculate net operating income on the Texas real estate exam?+
Start with gross potential rent (units times monthly rent times 12). Subtract vacancy and collection loss, add other income to reach effective gross income, then subtract operating expenses. The result is net operating income. NOI excludes debt service and income taxes.
What is the difference between gross potential rent and effective gross income?+
Gross potential rent assumes 100% occupancy. Effective gross income is what you actually collect after vacancy and collection loss, plus other income such as laundry or parking.
Is the property management fee based on gross or collected rent?+
Most exam questions apply the management fee to collected rent, after vacancy. Some questions use gross scheduled rent, so read the stem before you multiply.
Does net operating income include the mortgage payment?+
No. NOI excludes debt service (the mortgage payment) and income taxes. The mortgage payment is subtracted after NOI to find pre-tax cash flow.
Is this property management calculator for a real portfolio?+
No. It is built for Texas real estate exam preparation. Real operating budgets use actual leases, expense histories, reserves, and management agreements.
A 10-unit building rents for $1,200 per unit per month with 5% vacancy and $48,000 in operating expenses. What is the NOI?
GPR: 10 x 1,200 x 12 = $144,000. Less 5% vacancy ($7,200) = $136,800 collected. Minus $48,000 expenses = $88,800 NOI before other income. Add other income if the question gives it.
