Buying property as an investment? You need to know whether it pays off. Rental yield is the key metric to answer that question. But gross rental yield and net rental yield tell very different stories — and looking only at the gross figure paints an overly rosy picture. This article explains both metrics, reveals common cost traps, and walks through realistic examples. Use our free rental yield calculator to calculate your own rental yield instantly.
What Is Rental Yield?
Rental yield measures the ratio between rental income and capital invested. It shows what percentage return a rental property delivers per year — comparable to the interest rate on any other investment.
Two variants matter:
- Gross rental yield: rental income relative to the purchase price — no deductions
- Net rental yield: rental income minus all running costs, relative to total investment cost
How to Calculate Gross Rental Yield
Gross rental yield is the simplest metric. It ignores all ancillary costs and ongoing expenses:
Gross Rental Yield (%) = (Annual Rent ÷ Purchase Price) × 100Example: Gross Rental Yield
Purchase price: $250,000 · Monthly rent: $1,050
Annual rent: 1,050 × 12 = $12,600
Gross rental yield: 12,600 ÷ 250,000 × 100 = 5.04%
Gross rental yield works for a quick first comparison between properties. For an actual purchase decision, it falls short — the real costs remain hidden.
How to Calculate Net Rental Yield
Net rental yield accounts for actual costs. It is the honest metric for property investors:
Net Rental Yield (%) = ((Annual Rent − Running Costs) ÷ Total Investment Cost) × 100Where:
- Total investment cost = purchase price + closing costs (transfer tax, legal fees, agent fees)
- Running costs = non-recoverable expenses + maintenance reserve + management + vacancy allowance
Example: Net Rental Yield
Purchase price: $250,000 · Closing costs (8%): $20,000 · Total investment: $270,000
Annual rent: $12,600
Running costs: maintenance $2,500 + management $600 + non-recoverable $400 = $3,500
Net rental yield: (12,600 − 3,500) ÷ 270,000 × 100 = 3.37%
From 5.04% gross down to 3.37% net — a drop of over 30%. Anyone who only looks at gross rental yield massively overestimates their return.

Open Rental Yield CalculatorClosing Costs: The Hidden Yield Killer
Closing costs vary by country and region but typically range from 5% to 12% of the purchase price:
| Cost Type | Typical Range | On $250,000 Purchase |
|---|---|---|
| Transfer tax / stamp duty | 1–7% | $2,500–$17,500 |
| Legal & registration fees | 1–2% | $2,500–$5,000 |
| Agent / broker fees | 2–6% | $5,000–$15,000 |
| Total | 4–12% | $10,000–$37,500 |
These costs increase your invested capital without increasing the property's value. Every dollar of closing costs permanently reduces your yield.
Maintenance Costs: How Much Reserve?
Every property incurs ongoing maintenance costs. A common rule of thumb is 1–2% of the property value per year. More precise estimates depend on building age:
| Building Age | Reserve per sq ft/year | For 750 sq ft Unit |
|---|---|---|
| New build (< 10 years) | $0.70–$1.00 | $525–$750 |
| 10–30 years | $1.00–$1.50 | $750–$1,125 |
| Older (> 30 years) | $1.50–$2.50 | $1,125–$1,875 |
Underestimating maintenance leads to nasty surprises: a new roof, HVAC replacement, or window upgrades can easily cost five figures. An honest calculation protects against negative returns.
Vacancy: The Often-Ignored Risk
No tenant means no rental income — but costs keep running. A realistic vacancy allowance belongs in every serious yield calculation:
- High-demand cities: 1–2% vacancy allowance
- Mid-sized cities with stable demand: 3–5%
- Weaker markets or rural areas: 5–10% or more
Example: Vacancy in the Calculation
Annual rent: $12,600 · Vacancy allowance: 4%
Effective rental income: 12,600 × 0.96 = $12,096
Lost rent: $504 per year
Especially with older properties or in less popular locations, vacancy is a real risk. The buy vs. rent calculator helps with the overall comparison.
Rental Yield in Practice: Three Examples
Example 1: New Apartment in a Major City
Purchase price: $450,000 · Closing costs (8%): $36,000 · Rent: $1,800/month
Gross rental yield: (21,600 ÷ 450,000) × 100 = 4.80%
Net (after $5,400 costs): (21,600 − 5,400) ÷ 486,000 × 100 = 3.33%
Example 2: Existing Apartment in a Mid-Sized City
Purchase price: $150,000 · Closing costs (10%): $15,000 · Rent: $850/month
Gross rental yield: (10,200 ÷ 150,000) × 100 = 6.80%
Net (after $3,200 costs): (10,200 − 3,200) ÷ 165,000 × 100 = 4.24%
Example 3: Older Apartment in a Budget Market
Purchase price: $80,000 · Closing costs (10%): $8,000 · Rent: $550/month
Gross rental yield: (6,600 ÷ 80,000) × 100 = 8.25%
Net (after $2,800 costs + 5% vacancy): (6,600 × 0.95 − 2,800) ÷ 88,000 × 100 = 3.94%
The examples show: high gross yields in cheaper locations often shrink to levels comparable to expensive markets once maintenance and vacancy are factored in.

Open Rental Yield CalculatorRental Yield vs. Return on Equity
Rental yield considers only rental income. Return on equity additionally accounts for the leverage effect of financing:
Return on Equity = (Net Rental Income − Interest) ÷ Equity × 100With low interest rates, return on equity can be significantly higher than rental yield. When rates rise, leverage works in reverse. Anyone financing with a mortgage should always stress-test a rate increase — the mortgage calculator helps with that.
Common Mistakes When Calculating Rental Yield
1. Only looking at gross rental yield
Agents and sellers almost always advertise the gross figure. It ignores closing costs, maintenance and vacancy. Net rental yield is typically 30–50% lower.
2. Forgetting closing costs
8% closing costs on a $250,000 property add $20,000 to your invested capital. That alone drops your yield by nearly 0.5 percentage points.
3. Underestimating maintenance
A special assessment for a new roof can cost $10,000–$20,000. Budgeting $500 per year is wishful thinking. Realistic estimates are 1–2% of property value per year.
4. Ignoring vacancy
Even in popular locations, tenant turnover causes vacancy months. An allowance of at least 2–3% belongs in every calculation.
5. Overestimating rent increases
Rent control laws and market conditions limit increases. Always base your calculation on current rent — not wishful thinking.
What Is a Good Rental Yield?
Rules of thumb for net rental yield:
| Net Rental Yield | Assessment |
|---|---|
| < 2% | Weak — barely better than a savings account, high concentration risk |
| 2–3% | Average in major cities — only worthwhile with capital appreciation |
| 3–4% | Good — solid yield with positive cash flow |
| > 4% | Very good — rare in prime locations, check vacancy risk |
A low rental yield can still make sense if the location promises stable appreciation. Conversely, a high gross yield is worthless if vacancy and maintenance consume the cash flow. The ROI calculator shows how different asset classes compare.
Conclusion
Rental yield is the most important metric for property investors — but only net rental yield paints an honest picture. Closing costs, maintenance, and vacancy typically consume 30–50% of gross rental yield. Anyone buying property as an investment must factor in all costs and compare the net rental yield with alternative investments.
