Rental Yield Calculator
Use this calculator to estimate gross rental yield, net rental yield, NOI, and cash flow after financing costs.
What Is Rental Yield?
Rental yield is a quick way to estimate how much income a rental property produces compared with its cost. Investors use it to compare deals, locations, and property types before doing deeper analysis.
In simple terms, yield answers this question: "For every dollar I put into this property, how much rental return do I get each year?"
Gross Rental Yield
Gross yield uses rental income only and ignores expenses.
Gross Yield (%) = (Annual Rent / Total Acquisition Cost) × 100
It is useful for quick screening, but it can overstate performance if operating costs are high.
Net Rental Yield
Net yield includes vacancy and annual operating expenses, giving a more realistic number.
Net Yield (%) = ((Effective Annual Rent − Annual Operating Expenses) / Total Acquisition Cost) × 100
For most investors, net yield is the metric that matters more.
How to Use This Rental Yield Calculator
- Property Purchase Price: The contract price of the property.
- Upfront Purchase/Closing Costs: Stamp duty, legal fees, inspections, renovation at purchase, etc.
- Monthly Rent and Other Income: Expected recurring income.
- Vacancy Rate: The percentage of time the unit may be empty.
- Annual Operating Expenses: Ongoing ownership costs, excluding mortgage unless you want pure cash flow analysis.
- Annual Mortgage Payments: Optional field to estimate post-finance cash flow.
- Cash Invested: Optional field for cash-on-cash return.
Worked Example
Suppose you buy a property for $300,000 and spend $10,000 on closing and initial fixes. Monthly rent is $2,200, other income is $50, vacancy is 5%, and annual operating expenses are $6,500.
- Gross annual income = ($2,200 + $50) × 12 = $27,000
- Effective annual income after vacancy = $27,000 × 95% = $25,650
- NOI = $25,650 − $6,500 = $19,150
- Total acquisition cost = $310,000
- Gross yield = $27,000 / $310,000 = 8.71%
- Net yield = $19,150 / $310,000 = 6.18%
That single calculation already tells you much more than rent alone.
What Is a Good Rental Yield?
There is no universal answer. Good yields depend on market risk, tenant demand, financing costs, and long-term appreciation potential.
- 3% to 5% net yield: Common in expensive, high-demand cities.
- 5% to 8% net yield: Often considered balanced for many markets.
- 8%+ net yield: Can be very attractive, but double-check risks, vacancy, and maintenance profile.
Common Mistakes When Estimating Yield
- Ignoring vacancy entirely.
- Underestimating repairs and maintenance.
- Forgetting management fees for hands-off ownership.
- Comparing gross yields while pretending net costs are similar.
- Using unrealistic rent assumptions based on best-case listings.
Ways to Improve Rental Yield
Increase Effective Income
Reduce vacancy with better tenant screening, smart pricing, and quick turnover. Small income streams like parking or storage can also help.
Control Operating Costs
Shop insurance annually, reduce utility waste, and use preventive maintenance to avoid expensive emergency repairs.
Buy Better, Not Just Cheaper
The best yield improvements usually happen at purchase. A slightly better location with stronger tenant demand may outperform a cheaper but unstable rental market.
Final Thoughts
A rental yield calculator is a first-pass decision tool, not the full investment case. Use it to quickly rank opportunities, then follow up with deeper due diligence on capex, market trends, financing terms, tax implications, and exit strategy.
If you evaluate every potential deal with consistent assumptions, you will make better and faster property decisions.
