Key Takeaways
- Gross yield is annual rental income divided by purchase price. It ignores all costs and is useful for comparing raw income only.
- Net yield is (annual rental income minus operating expenses) divided by purchase price. This is the real number for investment comparison.
- Operating expenses include property tax, insurance, maintenance, management fees, and any capital expenditure. Mortgage interest is not an operating expense but a financing cost.
- According to ACRA, rental income must be declared to the tax authority. Expenses are deductible against rental income, subject to arm's length valuation rules.
- Compare properties on net yield using the same assumptions about vacancy and expense rates. A 3.5% net yield at 80% occupancy is different from 3.5% at 95% occupancy.
Rental yield is the single most important number when evaluating whether a rental property makes sense as an investment. It is not the only number downside risk, capital appreciation, and tax treatment all matter. But yield tells you the cash return on your capital right now, and the math is straightforward. Most rental property investors in Singapore chase yield and get disappointed because they calculate it wrong, or use gross yield and ignore real operating costs.
Gross yield vs net yield: which matters?
Gross rental yield is income divided by property cost with no deductions. If you buy a property for SGD 1 million and collect SGD 40,000 per year in rent, your gross yield is 40,000 / 1,000,000 = 4%. This number is useless for decision making because it tells you nothing about whether the investment is actually profitable.
Net rental yield subtracts all operating expenses before calculating the return. For the same SGD 1 million property, if you spend SGD 12,000 per year on property tax, insurance, maintenance, and management fees, your net income is SGD 28,000, and your net yield is 28,000 / 1,000,000 = 2.8%. This is the number that matters because it is what you actually keep in your pocket.
Always compare properties on net yield. Always. Gross yield is a vanity metric that leads investors into properties with high gross yields but crushing expense burdens.
How to calculate gross rental yield
How to calculate net rental yield
Net yield requires itemising all operating expenses. For a typical private condo or landed property in Singapore, the main expense categories are:
- Property tax (ACRA annual valuation): Typically 5% to 12% of the property's annual valuation, depending on location and property type. A SGD 1 million property might be assessed at SGD 100,000 to 120,000 annually, translating to SGD 5,000 to 14,400 in property tax.
- Maintenance and repairs: Budget 0.5% to 1.5% of property value annually. For a SGD 1 million property, set aside SGD 5,000 to 15,000 per year.
- Insurance: Typically SGD 1,500 to SGD 4,000 per year for full comprehensive coverage on a SGD 1 million property.
- Property management fees: If hiring a professional agent, budget 4% to 6% of monthly rental income. For SGD 3,500 monthly rent, this is SGD 1,680 to 2,520 per year.
- Utilities (if owner paid): Varies widely, typically SGD 100 to 300 per month (SGD 1,200 to 3,600 annually).
Notice the dramatic difference: gross yield of 3.78% becomes a net yield of 1.26%. This is why many rental properties feel disappointing. The gross yield looks reasonable until you pay the bills.
Rental income tax treatment in Singapore
According to the Inland Revenue Authority of Singapore (IRAS), rental income is taxable income and must be declared annually. For residents of Singapore, rental income is taxed at the progressive income tax rates (up to 22% marginal rate for high earners).
The key insight: allowed deductions reduce your taxable rental income. If you earn SGD 37,800 in rental income but claim SGD 25,200 in expenses, your taxable rental income is only SGD 12,600. Tax is then calculated on this net figure, not the gross.
This makes the net yield calculation even more important: your tax obligations are calculated against your net income, so tracking actual expenses is essential both for investment analysis and tax compliance.
Common yield calculation pitfalls
- Ignoring vacancy: Assuming 100% occupancy when realistic occupancy is 85% to 95% inflates gross yield. Always model conservatively.
- Forgetting property tax: Property tax is often the single largest operating expense and many investors overlook it when calculating net yield.
- Confusing mortgage interest with operating expenses: Mortgage interest is a financing cost, not an operating cost. It reduces your net cash flow but is not deducted when calculating yield on the property itself (it is deducted against rental income for tax purposes, which is separate).
- Comparing gross yield across properties: A property with 5% gross yield and 3% net yield is not comparable to a property with 4% gross yield and 3% net yield. Always compare on net.
- Using purchase price when property has appreciated: If you bought a property for SGD 800,000 and it is now worth SGD 1.2 million, the relevant yield is annual income divided by current value (SGD 1.2 million), not purchase price. The purchase price is sunk cost.
Winfred's Take
Investors in Singapore often ask me which property has better yield without telling me the net rental income. My response is always the same: show me the net yield after all expenses, and then we can compare. Gross yield is marketing. Net yield is reality. I have seen investors chase a 4% gross yield property that, after property tax and maintenance, delivers 1.2% net yield. That is not investing, that is charity with a mortgage. Know your actual return.

Frequently asked questions
What is a good net rental yield in Singapore?
For private properties in Singapore, net rental yields typically range from 1.5% to 3.5%, with higher yields available in specific pockets or older buildings. Central locations like the city fringe command lower yields (1.5% to 2.5%) because purchase prices are high relative to rental demand. Emerging areas and older properties outside the CBD can achieve 2.5% to 4% net yields. Anything above 4% net is exceptional in Singapore and warrants investigation into why the property is yielding so much.
Should I include mortgage interest in my yield calculation?
No. Mortgage interest is a financing cost, not an operating cost. Yield is calculated on the property itself, not on your equity. However, mortgage interest is deductible against rental income for tax purposes, so it reduces your taxable rental income and your tax bill. For after tax cash flow analysis (which is different from yield), include mortgage interest.
How does SSD affect net rental yield?
The Seller's Stamp Duty (SSD) is a tax levied on the seller when property is sold within a holding period (4 years for non-residential, varies for residential under the Additional Buyer's Stamp Duty framework). SSD does not directly affect rental yield because it is a cost borne at sale, not during the rental period. However, if you are modelling a hold then sell strategy, include SSD as a transaction cost when calculating total return.
Can I include capital expenditure (like a new roof) in my operating expenses?
Capital expenditure is a large, infrequent cost that extends the property's useful life (roof replacement, major renovations). Operating expenses are recurring annual costs (maintenance, property tax, insurance). For yield calculation purposes, operating expenses are the recurring annual costs. For tax purposes, capital expenditure may be depreciable depending on the asset class. Consult a tax advisor on how to treat capital expenditure in your specific situation.
