Cash On Cash Return

By Momin Ali Agha3/12/2026

What is Cash On Cash Return & Why Does It Matter?

Cash On Cash Return (COC) is a crucial metric for real estate investors, measuring the annual return on investment based on the property's cash inflows and outflows. It helps investors evaluate the profitability of a rental property, comparing it to other investment opportunities. A high COC indicates a better return on investment, while a low COC may signal a need to reassess the property's management or consider alternative investments.

How to Calculate Cash On Cash Return (The Formula)

The Cash On Cash Return formula is:

COC = (Annual Net Operating Income / Total Cash Invested) x 100

Where:

  • Annual Net Operating Income (NOI) = Gross Rental Income - Operating Expenses
  • Total Cash Invested = Down Payment + Closing Costs + Rehab/Renovation Costs

Step-by-Step Practical Example

Let's say you're considering purchasing a rental property with the following details:

Property DetailsValues
Purchase Price$200,000
Down Payment$40,000 (20%)
Closing Costs$8,000
Rehab/Renovation Costs$15,000
Gross Rental Income$30,000/year
Operating Expenses$10,000/year

Using the COC calculator, you input the values and get:

COC = (Annual Net Operating Income / Total Cash Invested) x 100 = (($30,000 - $10,000) / ($40,000 + $8,000 + $15,000)) x 100 = 12.5%

What is a "Good" Cash On Cash Return? (Industry Benchmarks)

A good COC varies depending on the location, property type, and market conditions. However, here are some general guidelines:

  • 8-12%: Average COC for single-family homes in stable markets
  • 10-15%: Average COC for apartments and multi-unit properties
  • 12-18%: Average COC for commercial properties or properties in high-growth areas

Keep in mind that these are general benchmarks, and a "good" COC ultimately depends on your investment goals and risk tolerance.

Common Mistakes to Avoid

When calculating COC, investors often make the following mistakes:

  • Ignoring closing costs and rehab expenses: Failing to account for these expenses can inflate the COC and lead to inaccurate investment decisions.
  • Not considering vacancy rates and rent fluctuations: Failing to account for potential vacancies and rent fluctuations can result in overly optimistic COC calculations.
  • Comparing COC across different property types: COC can vary significantly between property types, so it's essential to compare COC within the same property type or adjust for differences in property characteristics.
