How to calculate rental income

Rental income is more than the rent check. To know what a property really earns, work down from gross to cash flow:

  1. Gross scheduled income: monthly rent times 12, plus other income.
  2. Effective gross income: subtract a vacancy allowance for the weeks a unit sits empty.
  3. Net operating income: subtract operating expenses (taxes, insurance, repairs, management). Not the mortgage.
  4. Cash flow: subtract the mortgage from NOI. This is what lands in your pocket.

For return metrics on top of income, use the cap rate and cash-on-cash return calculators. For taxes, the Schedule E calculator.

Frequently asked questions

How do you calculate rental income?

Start with gross scheduled rent (monthly rent times 12, plus any other income like parking or laundry). Subtract a vacancy allowance to get effective gross income, then subtract operating expenses to get net operating income, and finally subtract the mortgage to get your pre-tax cash flow.

What is the difference between gross and net rental income?

Gross rental income is all the rent and other income a property collects. Net rental income (or net operating income) is what remains after vacancy and operating expenses, before financing. Lenders and the IRS care about different versions, so this calculator shows each step.

What counts as rental income for taxes?

Rent, advance rent, lease-cancellation payments, tenant-paid expenses, and the value of services received all count as rental income on Schedule E. This calculator estimates the cash picture; for the tax view use the Schedule E calculator.
