The capitalisation rate (cap rate) equals Net Operating Income divided by property value, expressed as a percentage. Unlike gross yield, it deducts operating costs before the calculation, giving you a true, unlevered picture of what a property earns relative to its price — an essential benchmark for comparing investments across locations and asset classes in Singapore (as of 2026-06).
You have found a condo in District 15 asking $1.8 million, and the agent quotes a 3.8% gross yield. It sounds reasonable — until you realise gross yield ignores property tax, maintenance fees, insurance, and vacancy. Strip those out and the actual return can be a full percentage point lower. That gap is exactly what the cap rate closes. Cap rate forces every cost onto the table before you divide by price, letting you compare any two properties on equal footing regardless of how they are financed — because leverage is deliberately excluded. Investors who skip the cap rate calculation routinely overpay or underprice risk; those who use it consistently make faster, more defensible buy and hold decisions.
What the Cap Rate Measures
The capitalisation rate answers one question: if you paid cash for this property and operated it for a year, what percentage of your purchase price would you earn back as net income? The formula is:
Cap Rate (%) = Net Operating Income (NOI) ÷ Property Value × 100
NOI is annual gross rent collected, minus all operating expenses: IRAS property tax at non-owner-occupier rates, MCST or maintenance fees, building insurance, budgeted repairs and management, plus a vacancy allowance (typically 5–8% of gross rent for Singapore private residential). Critically, NOI excludes mortgage interest payments and income tax — both are financing or ownership decisions, not property-level costs. This exclusion is intentional: by stripping out debt, cap rate becomes a property-level metric you can compare across all-cash or leveraged deals, across districts, and across asset types without distortion.
Cap Rate vs Gross Yield vs Cash-on-Cash Return
These three metrics answer three different questions. Gross yield (annual rent ÷ price) is the simplest benchmark but the least accurate: it ignores every operating cost, so it always flatters. Cap rate adds operating discipline — you see the unlevered net return. Cash-on-cash return goes further by factoring in your actual mortgage payments, giving the return on the equity you personally deployed. The three can diverge sharply: a property with 4.5% gross yield might have a 3.2% cap rate and a 5.8% cash-on-cash return if purchased with 75% debt at a low interest rate. Treating them as interchangeable is a common and costly error.
Key Inputs You Need Before You Calculate
To compute a reliable cap rate you need: (1) realistic annual gross rent based on current market comparables (use URA's Rental Statistics for verified transaction rents, as of 2026-06); (2) IRAS non-owner-occupier property tax (10% on Annual Value for the first $60,000 AV, 12% on the next $30,000, and progressive rates above that — budget conservatively); (3) MCST or condo maintenance fees; (4) building insurance; (5) repair and management allowance (1–2% of property value annually is a standard buffer); and (6) a vacancy allowance. Once you have all six, you are ready to calculate. You can also use the ShiokNest cap rate calculator to run scenarios quickly.

A Worked Example (as of 2026-06)
Take a two-bedroom condo in District 15 purchased at $1,800,000. Based on URA rental transaction data, comparable two-bedders in the area transact at roughly $4,200 per month (as of 2026-06), giving a gross annual rent of $50,400.
Now itemise operating expenses:
- IRAS property tax (non-owner-occupier): Annual Value (AV) for a $50,400-rent unit is typically assessed at $40,000–$44,000 by IRAS. At 10% on the first $30,000 AV and 12% on the next $12,000 AV, the annual bill is approximately $4,440. Budget $4,500.
- MCST maintenance fees: mid-range condo at ~$400/month = $4,800/year.
- Building insurance: contents and landlord liability, approximately $600/year.
- Repairs and management allowance: 1.5% of property value = $2,700/year.
- Vacancy allowance: 6% of gross rent ($50,400 × 0.06) = $3,024/year.
Total operating expenses: $4,500 + $4,800 + $600 + $2,700 + $3,024 = $15,624.
NOI = $50,400 − $15,624 = $34,776
Cap Rate = $34,776 ÷ $1,800,000 × 100 = 1.93%
Compare that to the gross yield: $50,400 ÷ $1,800,000 × 100 = 2.80%. The gap of nearly 0.9 percentage points is entirely made up of operating costs the gross yield figure hides.
Why Singapore Residential Cap Rates Are Typically Compressed
Across prime Singapore private residential, cap rates regularly sit in the 1.5–2.5% range, well below commercial real estate benchmarks globally and even below Singapore's own commercial-grade assets. The reason is straightforward: property prices are high relative to achievable rents. Buyers are paying a premium for capital preservation, scarcity, and currency stability, accepting a lower income yield in exchange for lower perceived risk and potential long-term appreciation. According to MAS economic commentary, Singapore's residential real estate has historically attracted capital seeking stability rather than yield maximisation. The practical implication: a cap rate below 2% signals a premium, lower-risk asset; a cap rate above 3% in Singapore private residential may indicate either a higher-yielding segment (such as older developments with lower prices) or higher embedded risk. Neither is inherently better — it depends on your investment objective.
Using Cap Rate to Compare Properties
Because cap rate strips out financing, you can apply it consistently across properties with different purchase structures. A $900,000 one-bedroom bought with 25% down and a $1,800,000 two-bedroom bought outright can be ranked by cap rate without worrying that one's return looks better simply because of lower equity deployed. This makes cap rate the standard for portfolio-level comparisons. Browse the rental yield map to see how different districts and segments compare, then cross-reference with ROI projections once you have settled on a shortlist.
Step-by-step: How to Calculate Your Cap Rate
- Confirm the purchase price or current market value. Use a recent comparable sale in the same development or district. The cap rate calculator accepts any price you input.
- Look up realistic gross annual rent. Search URA Rental Statistics for actual transacted rents in the development or nearby comparable projects (as of 2026-06). Avoid relying solely on asking rents in listings — transacted data is more reliable.
- Calculate IRAS non-owner-occupier property tax. Estimate the Annual Value (AV) — IRAS uses a comparable-rent benchmark, not your actual contracted rent. Apply the progressive non-owner-occupier tax table. When in doubt, budget 10–11% of your estimated AV as a conservative figure.
- Add maintenance, insurance, and repair costs. Obtain the actual MCST fee from the managing agent or the sales memorandum. Add building/landlord insurance (call for a quote; typically $400–$800/year for a condo unit). Budget 1–2% of property value annually for repairs and any managing-agent fee.
- Apply a vacancy allowance. Use 5% of gross annual rent as a minimum; 8% if the submarket shows softer demand. Do not assume 100% occupancy — even top-performing rentals experience changeover periods.
- Sum all operating expenses, then subtract from gross annual rent to get NOI. Double-check that you have excluded mortgage repayments and personal income tax — these go into cash-on-cash return, not cap rate.
- Divide NOI by property value and multiply by 100. This is your cap rate percentage.
- Benchmark against the district. Check the rental yield map to see whether your cap rate is above or below the district average. A materially lower cap rate may indicate you are paying a premium; a materially higher one may flag higher risk or a below-market rent assumption.
- Stress-test with the ROI calculator. Once you have a cap rate, run a full ROI projection factoring in financing costs, holding period, and expected capital appreciation to see total return.
Frequently asked questions
Is a higher cap rate always better for a Singapore investor?
Not necessarily. A higher cap rate in Singapore residential often reflects lower asset quality, an older development, or a less desirable location — factors that may compress long-term capital appreciation. Investors who prioritise stable capital preservation typically accept compressed cap rates (1.5–2%) in prime districts. Those seeking income-focused returns may target secondary-market units at 2.5–3%+, accepting higher management risk and potentially slower price growth. Match the cap rate target to your investment objective rather than chasing the highest number in isolation.
What is the difference between cap rate and gross rental yield?
Gross rental yield divides annual gross rent by the purchase price without deducting any costs, so it always overstates the real return. Cap rate deducts all operating expenses — property tax, maintenance, insurance, repairs, and vacancy — before dividing by value. In Singapore, the gap between gross yield and cap rate is typically 0.7–1.2 percentage points depending on the property type and age. Always use cap rate (or at minimum net yield) when making final investment decisions; gross yield is useful only for quick initial screening.
Should I use purchase price or current market value in the cap rate formula?
Use the figure relevant to your decision. If you are evaluating a purchase, use the asking or negotiated purchase price — this tells you the yield you are buying at. If you already own the property and want to assess its current performance or decide whether to sell, use current market value — this is the "opportunity cost" cap rate, showing what you would earn if you redeployed the capital today. The two can differ significantly for properties held for several years in an appreciating market, and comparing them highlights whether holding or selling makes more financial sense.
How does IRAS property tax affect my cap rate calculation?
Property tax is one of the largest operating costs for a Singapore rental property and must be included in NOI. Non-owner-occupier rates are progressive: 10% on Annual Value up to $30,000, 12% on the next $30,000 AV, and higher for very high-value properties. Because IRAS uses its own AV assessment (based on comparable market rents, not your actual contracted rent), your actual tax bill can differ slightly from a simple percentage of rent. Always obtain an IRAS AV estimate for the specific unit or use recent AV notices as a reference before finalising your cap rate calculation.
Can I use cap rate to evaluate HDB flats or only private condos?
Cap rate is applicable to any income-producing property, including HDB flats eligible for subletting. However, there are practical differences: HDB lease decay is a material long-term risk (the property reverts to HDB at lease end), and HDB properties cannot be owned by corporations. Lease decay significantly affects resale value, which must be factored into any investment thesis. For a comprehensive picture on HDB, pair the cap rate calculation with the lease decay calculator to model how declining remaining lease affects future resale value and total return.
