Rental Yield, Cap Rate & ROI Estimator

Commercial & Residential Income Property Valuation & Return Underwriter

Calculate Gross & Net Rental Yields, Capitalization Rate (Cap Rate), Net Operating Income (NOI), Cash-on-Cash ROI, and capital growth appreciation.

Input Specifications

Primary Planning Output
6.31%

Net Operating Income of $22,700 / Purchase Price of $360,000.

Detailed Bill of Quantities

  • Net Operating Income (NOI) $22,700
  • Gross Rental Yield 8.33%
  • Leveraged Cash-on-Cash Return (Proxy) 1.21%
  • Projected Annual Capital Growth $12,600
  • Annual Gross Rental Income $30,000

Calculation Formula Steps

Gross Annual Rent

$2,500 × 12 months = $30,000

Effective Gross Income

$30,000 - 5% Vacancy ($1,500) = $28,500

Net Operating Income (NOI)

$28,500 - $5,800 (Opex) = $22,700

Unleveraged Cap Rate

($22,700 ÷ $360,000) × 100 = 6.31%

Understanding the Rental Yield, Cap Rate & ROI Estimator

What This Calculator Does

Calculates Gross Rental Yield, Capitalization Rate (Cap Rate), Net Operating Income (NOI), and leveraged Cash-on-Cash Return for investment real estate.

When to Use This Tool

  • Screening buy-to-let residential properties, multifamily acquisitions, and commercial real estate investments.

Input Parameters and Measurement Guidelines

Accurate estimates require precise field measurements. Review each parameter purpose and measurement method below:

Parameter Engineering Purpose How to Measure on Site
Property Acquisition Price ($) Total purchase cost of the real estate asset. Contract purchase price including immediate capital improvements.
Gross Monthly Rent ($) Anticipated monthly rental income from tenants. Market rental comparables for equivalent neighborhood units.
Vacancy & Credit Loss (%) Allowance for tenant turnover and uncollected rent (typically 5-8%). Local submarket historical vacancy rate.
Annual Operating Expenses ($) Property management, repairs, insurance, taxes, and maintenance fees (excluding debt service). Sum of operating budget lines.

Worked Engineering or Planning Example

Scenario: Duplex Residential Rental ($350,000 Purchase)

Price = $350,000, Down Payment = $70,000, Rent = $2,600/mo, Vacancy = 5%, Opex = $6,200/yr

Step-by-Step Calculation:
  • Gross annual scheduled rent = $2,600 × 12 = $31,200.
  • Vacancy allowance (5%) = $31,200 × 0.05 = $1,560.
  • Effective gross income = $31,200 - $1,560 = $29,640.
  • Net Operating Income (NOI) = $29,640 - $6,200 = $23,440.
  • Gross Rental Yield = ($31,200 ÷ $350,000) × 100 = 8.91%.
  • Cap Rate = ($23,440 ÷ $350,000) × 100 = 6.70%.

Estimated Order Output: Gross Yield is 8.91%, Net Operating Income is $23,440/yr, and the unleveraged Cap Rate is 6.70%.

Plain-Language Formula

Gross Yield = (Annual Gross Rent ÷ Price) × 100. NOI = Effective Rent - Opex. Cap Rate = (NOI ÷ Price) × 100.

Rounding Rules and Units

Financial rates expressed in percentages (%) with two decimals; values in local currency.

Assumptions and Default Values

  • Cap rate reflects unleveraged asset yield independent of financing structure.
  • Opex excludes income taxes, depreciation, and mortgage debt service.

What the Result Does Not Include

  • • Tenant leasing commissions, major capital expenditure (CapEx) roof/HVAC replacements, and individual investor tax brackets.

Common Mistakes

  • ✕ Relying solely on Gross Yield while ignoring high local property taxes or special HOA assessments that devastate Net Operating Income.
  • ✕ Assuming zero vacancy throughout a multi-year hold period.

Frequently Asked Questions

What is the difference between Cap Rate and Cash-on-Cash Return? ▼
Cap Rate is an unleveraged metric (Net Operating Income divided by total Purchase Price). Cash-on-Cash Return measures net cash flow after debt service relative to your initial cash equity. In this calculator, Cash-on-Cash is provided as a proxy assuming standard 30-year 6.5% financing.
What is considered a good Cap Rate for rental real estate? ▼
Typical residential and commercial cap rates range from 4% to 6% in prime tier-1 metropolitan markets and 7% to 10%+ in secondary or emerging markets with higher risk profiles.
What expenses should be included in Annual Opex? ▼
Include property taxes, landlord hazard insurance, property management fees (typically 8-10%), maintenance/repairs, utilities paid by owner, and replacement reserve funds.
What is Gross Yield vs. Net Yield? ▼
Gross Yield is simply total annual rent divided by purchase price. Net Yield subtracts all operating expenses and vacancy losses first, providing a far more realistic measure of income.
