You’re looking at a real estate listing. You’re looking at a real estate listing. The agent’s description glows: “A cash-flowing machine!” The numbers show a 7% Cap Rate. But what does that really mean for your bank account after you pay the mortgage, taxes, and set aside money for a new roof in ten years?
The disconnect between impressive-sounding metrics and actual, spendable cash is where many new investors get lost. Free Cash Flow Yield (FCFY) is the one number that cuts through the noise. It answers the most critical question: “What is my property’s true take-home pay?”

What is Free Cash Flow Yield (FCFY)?
Free Cash Flow Yield is the annual percentage return on the actual cash you invested, after every single bill—both present and future—is accounted for. It’s the ultimate measure of an investment deal’s performance for you.
The power is in the word “free.” This isn’t theoretical profit tied up in the property; it’s cash that is free and clear for you to use. You can reinvest it, save for the next property, or pay yourself. FCFY is your “sleep-well-at-night” number because it forces you to plan for major future expenses, separating savvy investors from amateurs who get surprised by big bills.
Key Attributes
- Cash-Focused: It ignores non-cash deductions like depreciation and focuses only on the cash moving in and out of your bank account.
- Forward-Looking: Unlike other metrics, it forces you to account for Capital Expenditures (CapEx)—the money you must save for future big-ticket replacements like a roof or HVAC system.
- Personalized: It is calculated based on your specific financing (down payment and loan terms), making it a true reflection of the deal’s value to you as an individual investor.
The Free Cash Flow Yield (FCFY) Formula
To calculate Free Cash Flow Yield, you’ll use this formula:
FCFY (%) = [Annual Free Cash Flow / Total Cash Invested] * 100
Calculation Example: Let’s Analyze a Duplex
Theory is great, but let’s get our hands dirty. We’ll analyze a fictional duplex together to see how FCFY reveals the real story.
- Property: A $350,000 duplex.
- Your Deal: 20% down payment ($70,000) + $10,000 in closing costs.
- Total Cash Invested = $80,000
- Income: Each unit rents for $1,500/month.
- Gross Annual Rent = $36,000
Here’s a step-by-step guide to calculating FCFY:
Step 1: Calculate Net Operating Income (NOI)
This is your income after all operating expenses but before your mortgage.
- Gross Rent ($36,000) – Vacancy (5% = $1,800) – OpEx (Taxes, Insurance, Repairs = $8,000) = NOI of $26,200
Pro Tip: Where to Find These Numbers
Don’t guess! For any property you’re analyzing:
- Taxes: Look up the property’s tax history on the county assessor’s website.
- Insurance: Call a local insurance agent and ask for a landlord policy quote. It takes 10 minutes.
- Repairs/Vacancy: A conservative estimate is 5% of gross rent for each.
Step 2: Subtract Your Annual Mortgage Payment
This is your total principal and interest paid over the year.
- Assuming a $280,000 loan at 6%, $20,150.
- NOI (
26,200)−Mortgage(26,200)−Mortgage(20,150) = $6,050 cash flow before CapEx.
Step 3: Subtract Your Annual CapEx Savings
This is your “future-proofing fund.” We’ll set aside 8% of gross rent.
- CapEx Savings = $36,000 x 8% = $2,880 per year.
Step 4: Calculate Your FCFY
First, find your final Free Cash Flow (your true take-home pay).
- Cash Flow from Step 2 (
6,050)− CapExSavings(6,050) − CapExSavings(2,880) = $3,170 Annual Free Cash Flow.
Now, apply the formula:
- $3,170 (Free Cash Flow) / $80,000 (Total Cash Invested) = 0.0396
- 0.0396 * 100 = 4.0% Free Cash Flow Yield
Why is Free Cash Flow Yield Crucial for Investors?
FCFY provides significant benefits by painting the most realistic picture of an investment’s health.
- Cuts Through the Hype: It ignores misleading sales pitches and focuses on the only thing that matters: how much cash you actually get to keep.
- Forces Long-Term Thinking: By including CapEx, it prevents you from being blindsided by predictable, major expenses down the road. A property with great monthly cash flow but an ancient roof is a ticking time bomb that FCFY exposes.
- Enables True “Apples-to-Apples” Comparisons: It allows you to compare a real estate deal not only to another property but also to entirely different investments, like an S&P 500 index fund, to see where your cash is working hardest.
An Alternative to FCFY: Capitalization Rate (Cap Rate)
While FCFY is the ultimate metric for personal deal analysis, you will frequently encounter Cap Rate. It’s important to know the difference.
| Metric | Description | Best Used For | Key Advantage | Key Limitation |
| Cap Rate | Measures a property’s unleveraged potential return (NOI / Property Price). | Quickly comparing properties in a market, as if paying all cash. | Objective, market-level data for broad analysis. | Ignores your personal financing and crucial CapEx costs. |
| FCF Yield | Measures the actual return on your invested cash after all expenses. | Deciding if a specific deal is a good investment for you. | A complete, personalized, and realistic picture of your return. | Requires more inputs and is specific to your deal structure. |
In short: Cap Rate analyzes the property. Free Cash Flow Yield analyzes the deal for you.
Common Pitfalls and Limitations
When calculating FCFY, be aware of these common mistakes:
- Underestimating CapEx: This is the most common error. Being too optimistic about the lifespan of major systems will artificially inflate your FCFY and leave you unprepared for future costs.
- Forgetting Closing Costs: Your “Total Cash Invested” is not just your down payment. It must include all closing costs, inspection fees, and initial repair funds to be accurate.
- Using Unrealistic Projections: Do not rely solely on the seller’s provided numbers for rent or expenses. Do your own research to verify market rents and estimate costs.
