Key Takeaways
Gross rental yield in Singapore typically ranges from 2.5% to 4% for private condos.
Net yield drops significantly after factoring in vacancy, maintenance, property tax, and agent fees.
A positive monthly cash flow does not guarantee a good total ROI — capital appreciation matters too.
The expense ratio (vacancy + repairs + fees) typically runs 15-25% of gross rental income.

Why It Matters
Singapore is one of the most popular property investment markets in Asia, but that does not mean every condo is a good investment. Understanding real rental yield — not the headline gross yield agents promote — is the difference between a profitable portfolio and a money pit. This calculator matters because:

Review the results — The calculator updates instantly as you change any input. Key metrics include gross yield, net yield, total rental income, and future property value. Charts show your cash flow and cumulative return over time.
Run what-if scenarios — This is where the real power lies. Change one variable at a time to see its impact. For example, try increasing the interest rate by 1% or extending your holding period by 5 years. Note how the results shift.
Compare and decide — Run 2-3 different scenarios and note the results. This gives you a range of outcomes to base your decision on, rather than relying on a single projection.

How to read this:
The rental math: At $3,800/month, Raj earns $45,600/year gross. After deducting 15% for vacancy, repairs, and agent fees, his net rental income is $38,760/year. Over 5 years, that is $193,800 in net rental income. Capital appreciation: If the property appreciates at 3% per year, it will be worth $1,738,911 when Raj sells — a capital gain of $238,911 on top of his rental income.
Tips & Pitfalls
Expert Tips
Use realistic assumptions — Singapore condo appreciation has historically averaged 2-4% per year. Avoid overly optimistic projections. When in doubt, use 3% as a baseline.
Use 15-20% expense ratio — New investors often underestimate vacancy, repairs, and agent fees. A 15% expense ratio is conservative; 20% is safer for older properties.
Cross-check rents on ShiokNest — Before plugging in a rental figure, check recent rental transactions for similar units in the same development.
Common Pitfalls
Using gross rental yield as the measure of investment returns
Assuming 100% occupancy throughout the holding period
Ignoring the impact of interest rate changes on cash flow
Frequently Asked Questions
What is a good rental yield in Singapore?
Gross rental yields for private condos typically range from 2.5% to 4%. After accounting for expenses (vacancy, maintenance, property tax, agent fees), net yields are usually 1.5-3%. Yields above 3.5% gross are considered above average.
How is Buy-to-Rent ROI different from rental yield?
Rental yield only measures annual rent vs property price. Total ROI includes capital appreciation (or depreciation), mortgage interest savings, and all holding costs over the entire period. A property with low yield can still deliver high total ROI through price growth.
What expense ratio should I use?
A realistic expense ratio for Singapore condos is 15-25% of gross rent. This covers 1-2 months vacancy per tenancy cycle, maintenance repairs, condo management fees not covered by tenant, and agent commission (typically 1 month rent per 2-year lease).
Does the calculator account for rental income tax?
The calculator includes property tax as an input. Rental income itself is taxed at your personal income tax rate after deducting allowable expenses (mortgage interest, property tax, repairs, agent fees). Consult IRAS guidelines for detailed tax treatment.
