Investment Property & Real Estate Calculator
Is an investment property worth buying? Rental income is only part of the equation. Mortgage payments, property taxes, maintenance costs, and appreciation all affect your potential return.
Use our free Investment Property Calculator to estimate rental cash flow, calculate your return on investment, and see how your property's value and equity could grow over time.
How does owning investment property affect your retirement plan?
Real estate can provide an additional source of retirement income, but it's important to understand how rental income, ongoing expenses, and a future property sale fit into your overall financial picture.

How this estimate works: Annual rent, vacancy, and operating expenses are held constant in the projections. Loan payments are calculated monthly. Appreciation compounds annually. The simplified first-year tax estimate subtracts mortgage interest and assumed depreciation from operating income, then applies the estimated tax rate; it does not model every deduction, passive loss restriction, tax bracket, depreciation convention, capital-gains tax, depreciation recapture, purchase/sale transaction costs, or financing fees. The cash-on-cash calculation excludes unentered closing costs. Negative taxable income creates no immediate tax benefit in this model. These results are illustrative, not a guarantee or tax advice.
Investment Property Calculator Definitions
Cash Invested
The total amount of your own money used to purchase the investment property. This generally includes your down payment, closing costs, and any initial improvements or expenses paid out of pocket.
Interest Rate
The annual interest rate charged on your mortgage or investment property loan. This rate determines how much interest you'll pay on the outstanding loan balance.
Land Value
The estimated portion of the property's purchase price attributable to the land. Land cannot be depreciated for tax purposes, so its value is separated from the building value when calculating depreciation.
Personal Property
Assets associated with the rental property that are separate from the building itself. Examples include appliances, furniture, and certain equipment used to operate or maintain the property.
Personal Property Depreciation Rate
The annual depreciation rate applied to eligible personal property. Different types of assets have different depreciation schedules under IRS rules.
For example, certain appliances and furniture used in a residential rental property may qualify for a five-year recovery period under the Modified Accelerated Cost Recovery System (MACRS).
Building Value Depreciation Rate
The rate used to calculate annual depreciation on the building portion of the investment property.
Residential rental buildings are generally depreciated over 27.5 years, while nonresidential buildings are generally depreciated over 39 years under federal tax rules. Land is excluded from depreciation.
Appreciation
The average annual percentage increase you expect in the property's market value.
For example, a property worth $300,000 that appreciates by 3% annually would have an estimated value of approximately $347,800 after five years.
Actual property values can increase or decrease depending on market conditions.
Loan Principal & Interest (P&I)
The two primary components of a mortgage payment.
Principal: The portion of your payment that reduces the outstanding loan balance.
Interest: The amount paid to the lender for borrowing the money.
Principal payments increase your equity in the property, while interest payments are a financing expense.
Total Depreciation
The combined annual depreciation expense associated with the building and eligible personal property.
Depreciation is a noncash expense that may reduce taxable rental income. The actual tax benefit depends on applicable tax rules and your individual circumstances.
Gross Operating Income
The income generated by the property after accounting for vacancy and any other adjustments included in the calculator.
For example, if a property generates $30,000 in potential annual rental income and has a 5% vacancy allowance, its effective rental income would be $28,500.
Total Annual Operating Expenses
The estimated annual costs of owning and operating the rental property, excluding mortgage principal and interest payments.
Typical expenses include property taxes, insurance, repairs, maintenance, property management fees, utilities, and other operating costs.
Operating Expense Ratio
The percentage of a property's effective operating income used to cover operating expenses.
For example, if a property generates $40,000 in annual operating income before expenses and has $12,000 in operating expenses, its operating expense ratio is 30%.
A lower operating expense ratio generally indicates that a greater portion of rental income remains available to cover financing costs and generate cash flow.
Net Operating Income (NOI)
The property's annual operating income after subtracting operating expenses, but before deducting mortgage payments, income taxes, and depreciation.
For example, a property generating $36,000 in annual rental income with $12,000 in operating expenses would have an NOI of $24,000.
NOI is a commonly used measure of a rental property's operating profitability.
Cash Flow Before Tax
The amount of money remaining from rental operations after paying operating expenses and mortgage principal and interest.
For example, if a property generates $24,000 in annual NOI and has $18,000 in annual mortgage payments, its cash flow before tax would be $6,000.
This represents the property's estimated annual cash flow before income taxes.
Annual Debt Service
The total amount paid toward property loans during the year, including principal and interest.
For example, a monthly mortgage payment of $1,500 results in annual debt service of $18,000.
Return on Investment With Appreciation
An estimated annual investment return that includes cash flow before taxes, mortgage principal reduction, estimated tax benefits or costs, and property appreciation, divided by the initial cash invested.
This calculation includes both cash returns and increases in property equity.
Keep in mind that appreciation is an unrealized gain until the property is sold.
Return on Investment Without Appreciation
An estimated annual investment return based on cash flow before taxes, mortgage principal reduction, and estimated tax benefits or costs, divided by the initial cash invested.
This measure excludes changes in the property's market value, making it useful for evaluating investment performance without relying on expected appreciation.
Capitalization Rate (Cap Rate)
A measure of a property's annual net operating income relative to its purchase price or current market value.
Cap Rate = Net Operating Income ÷ Property Value × 100
For example, a property worth $400,000 with an NOI of $24,000 has a cap rate of 6%.
Cap rate excludes mortgage financing and is commonly used to compare the operating returns of different investment properties.
Cash-on-Cash Return
The annual cash flow before taxes divided by the total cash invested in the property.
Cash-on-Cash Return = Annual Cash Flow Before Tax ÷ Cash Invested × 100
For example, if you invest $100,000 in a property and generate $8,000 in annual cash flow before taxes, your cash-on-cash return is 8%.
Unlike cap rate, cash-on-cash return accounts for mortgage financing and focuses on the cash income generated relative to your initial investment.
