Rental Yield Calculator - Gross & Net Yield

Formula

Gross Yield = (Annual Rent / Property Price) × 100

Gross yield divides annual rent by purchase price. Net yield subtracts operating expenses. Cap rate uses NOI (before mortgage). Cash-on-cash divides cash flow by your invested capital.

Worked Examples

Example 1: Positive Cash Flow Analysis

Problem: $250K property, $1,800/mo rent, 25% down, 6.5% interest rate. Is it cash flow positive?

Solution: Property Price: $250,000\nDown Payment: 25% = $62,500\nLoan Amount: $187,500\n\nMortgage Payment (30-year): $1,185/mo\n\nMonthly Income:\nRent: $1,800\nVacancy (5%): -$90\nEffective rent: $1,710\n\nMonthly Expenses:\nProperty tax: $260 (~1.25%/year)\nInsurance: $100\nMaintenance: $180 (10% of rent)\nTotal: $540\n\nCash Flow = $1,710 - $540 - $1,185 = -$15/mo\n\nAlmost break-even! Small rent increase or lower expenses makes it positive.

Result: -$15/mo cash flow | 8.6% gross yield | 5.2% cap rate

Example 2: Comparing Two Investment Properties

Problem: Property A: $400K, $2,500/mo rent, expensive area. Property B: $200K, $1,600/mo rent, growing suburb. Which is better?

Solution: Property A:\nGross Yield: ($2,500 × 12) / $400,000 = 7.5%\nEstimated expenses: 35% = $10,500\nNOI: $30,000 - $10,500 = $19,500\nCap Rate: 4.9%\n\nProperty B:\nGross Yield: ($1,600 × 12) / $200,000 = 9.6%\nEstimated expenses: 35% = $6,720\nNOI: $19,200 - $6,720 = $12,480\nCap Rate: 6.2%\n\nProperty B: Higher yield, better cap rate\nProperty A: Better appreciation potential?\n\nWith 20% down and similar rates:\nA: Cash flow ~$200/mo on $80K invested\nB: Cash flow ~$350/mo on $40K invested\n\nProperty B offers better immediate returns.

Result: Property B: 9.6% yield, 6.2% cap vs A: 7.5% yield, 4.9% cap

Example 3: Impact of Different Down Payments

Problem: $300K property, $2,000/mo rent. Compare 10%, 20%, and 25% down payment scenarios.

Solution: Gross rent: $24,000/yr, Expenses: $7,200/yr\nNOI: $16,800, Cap Rate: 5.6%\n\n10% Down ($30K invested):\nLoan: $270K, Payment: $1,707/mo = $20,484/yr\nCash Flow: $24K - $7.2K - $20.5K = -$3,684/yr\nCash-on-Cash: -12.3% (negative!)\n\n20% Down ($60K invested):\nLoan: $240K, Payment: $1,517/mo = $18,204/yr\nCash Flow: $24K - $7.2K - $18.2K = -$1,404/yr\nCash-on-Cash: -2.3%\n\n25% Down ($75K invested):\nLoan: $225K, Payment: $1,422/mo = $17,064/yr\nCash Flow: $24K - $7.2K - $17.1K = -$264/yr\nCash-on-Cash: -0.4% (almost break-even)\n\nHigher down payment = better cash flow but lower leverage.

Result: 10% down: -$307/mo | 20% down: -$117/mo | 25% down: -$22/mo

Frequently Asked Questions

What is rental yield and how is it calculated?

Rental yield measures annual rental income as a percentage of property value. Gross Yield = (Annual Rent ÷ Property Price) × 100. Net Yield = (Annual Rent - Operating Expenses) ÷ Property Price × 100. Example: $300K property with $24K annual rent = 8% gross yield. Net yield after $6K expenses = 6% yield. Good benchmarks: 7-10% gross yield for residential, 5%+ net yield.

What is a good rental yield for investment property?

Depends on market and property type. General benchmarks: Gross yield 7-12% is good for residential. Below 5% may not cover costs. Above 12% rare (often signals higher risk area or hidden issues). Higher-priced markets (coastal cities) often have 3-5% yields but better appreciation. Lower-priced markets offer 8-12% yields but less growth. Balance yield with appreciation potential.

How does vacancy rate affect my rental income?

Vacancy rate reduces effective rental income. Common assumption: 5-8% vacancy (roughly 1 month vacant per year). Calculate: Effective Rent = Gross Rent × (1 - Vacancy Rate). $2,000/mo rent with 5% vacancy = $22,800 effective annual rent (not $24,000). Account for tenant turnover, renovation periods, and local market conditions. Hot markets: 3-5%. Soft markets: 10-15% or higher.

What expenses should I include in rental property calculations?

Operating expenses (for NOI/cap rate): Property taxes (1-3% of value annually), Insurance ($800-2,000/year), Maintenance/repairs (1% of value or 10% of rent), Property management (8-12% of rent if hired), Vacancy allowance (5-10%), HOA fees if applicable. Exclude from NOI but include for cash flow: Mortgage principal and interest. Budget 30-40% of gross rent for total expenses.

What is Net Operating Income (NOI) and why does it matter?

NOI = Gross Rental Income - Operating Expenses (excluding mortgage). It measures property's earning power independent of financing. Used for: calculating cap rate, comparing properties fairly, determining property value (Value = NOI ÷ Cap Rate), qualifying for commercial loans. Example: $24K rent - $8K expenses = $16K NOI. At 5% cap rate, property worth $320K. NOI is the most important metric for property valuation.

How do I calculate if a rental property is cash flow positive?

Cash Flow = Gross Rent - Vacancy - Operating Expenses - Mortgage Payment. Example: $2,000/mo rent, 5% vacancy ($100), $400 expenses, $1,500 mortgage. Cash flow = $2,000 - $100 - $400 - $1,500 = $0 (break-even). Many investors target $100-200+ positive monthly cash flow per door. Negative cash flow requires appreciation or tax benefits to justify.

Background & Theory

The Rental Yield Calculator applies the following established principles and formulas. Real estate investment analysis relies on a set of income-based metrics that translate property performance into comparable figures. Net Operating Income (NOI) is the annual income generated by a property after operating expenses but before debt service and taxes: NOI = Gross Rental Income - Vacancy Allowance - Operating Expenses. The capitalization rate (cap rate) expresses the relationship between NOI and property value: Cap Rate = NOI / Property Value. A higher cap rate signals greater income relative to price — and typically greater perceived risk or a weaker market — while lower cap rates characterize prime assets in supply-constrained markets. The Gross Rent Multiplier (GRM) offers a quicker, rougher valuation: GRM = Purchase Price / Annual Gross Rent. Investors use it to filter properties before conducting full underwriting. The Loan-to-Value (LTV) ratio, calculated as the mortgage balance divided by appraised value, determines a borrower's leverage and is a primary driver of both mortgage rate and lender approval. Conventional lenders in the US typically require LTV below 80 percent to avoid private mortgage insurance. Cash-on-cash return measures annual pre-tax cash flow as a percentage of total cash invested: CoC = Annual Cash Flow / Total Cash Invested. This metric is distinct from overall return because it isolates the performance of the equity component after servicing debt. Mortgage amortization creates a second wealth-building channel alongside appreciation: each monthly payment reduces the outstanding principal, transferring ownership from the lender to the borrower over the loan term. Standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is the monthly rate, and n is the number of payments. In early years, most of each payment is interest; in later years, principal repayment accelerates. Appreciation and income return together constitute total return, and the optimal mix between them varies by market cycle, property type, and investor tax situation.

History

The history behind the Rental Yield Calculator traces back through the following developments. Formal systems of property rights trace their roots to ancient civilizations. Roman law developed sophisticated concepts of ownership, usufruct, and easements that influenced Western legal systems for two millennia. English common law codified property rights through statutes of mortmain and the Statute of Uses, laying groundwork for the modern mortgage — derived from the Old French meaning dead pledge, because the debt died either when repaid or when the creditor foreclosed. In the United States, the Homestead Act of 1862 granted 160 acres to settlers who improved the land, catalyzing westward expansion and creating a culture of owner-occupied housing. The federal government's role expanded dramatically in the twentieth century. The Great Depression devastated real estate values; the Federal Home Loan Bank System was created in 1932 and the Federal Housing Administration in 1934 to restore mortgage credit and standardize the long-term amortizing mortgage. The GI Bill of 1944 subsidized home loans for veterans, fueling the suburban boom of the 1950s and 1960s. Rising homeownership rates transformed real estate into the primary store of wealth for American middle-class households. The Savings and Loan crisis of the 1980s exposed the dangers of maturity mismatch — funding long-term mortgages with short-term deposits — combined with deregulation and fraud. Approximately 1,000 thrift institutions failed, costing taxpayers an estimated 160 billion dollars. The Resolution Trust Corporation was created in 1989 to manage and sell off failed institutions' assets. The 2008 global financial crisis stemmed from the originate-to-distribute model in which mortgage originators sold loans into securitization vehicles with little regard for borrower creditworthiness. The collapse of the subprime market triggered a cascade of writedowns at global financial institutions and led to the deepest recession since the 1930s. The Dodd-Frank Act of 2010 introduced qualified mortgage standards and risk-retention requirements. Post-pandemic monetary easing drove US home prices to record highs between 2020 and 2022, followed by a sharp slowdown as the Federal Reserve raised rates aggressively from 2022 onward.
