Every expat heading to Asia eventually faces the same question: Hong Kong or Singapore? Both cities sit at the top of every global cost-of-living ranking, both offer world-class infrastructure and career opportunities, and both are eye-wateringly expensive compared to most of the world. But the way each city costs you money is surprisingly different.
We have spent the past month pulling together the latest data, cross-referencing official government sources, and comparing the real-world numbers across the categories that matter most to expats. The short version: Hong Kong is slightly cheaper overall, but the gap is narrower than most people expect, and the real decider is tax.
Where Hong Kong and Singapore Rank Globally
According to the Mercer Cost of Living Survey 2024, Hong Kong is the most expensive city in the world for international employees, with Singapore in second place. Zurich, Geneva, and Basel fill out the top five. Both cities have held these positions consistently for the past several years.
Numbeo’s composite index, which aggregates user-reported data across rent, groceries, restaurants, and transport, puts Hong Kong at approximately 16 to 17 percent cheaper than Singapore overall. That figure is a useful baseline, but it obscures important differences between individual categories. Rent, for example, tells one story. Tax tells another entirely.
Housing and Rent
Rent is the largest single expense for expats in both cities, and it is where Singapore pulls ahead in cost.
| Category | Singapore (USD/month) | Hong Kong (USD/month) | Difference |
| 1-bedroom, city centre | 2,580 | 2,070 | HK 20% cheaper |
| 1-bedroom, outside centre | 1,980 | 1,580 | HK 20% cheaper |
| 3-bedroom, city centre | 5,310 | 4,650 | HK 12% cheaper |
| 3-bedroom, outside centre | 3,560 | 3,030 | HK 15% cheaper |
Figures converted from Numbeo SGD data at approximately 1 SGD = 0.75 USD, rounded. City centre in HK means Central/Admiralty/Mid-Levels; in SG means Orchard/River Valley/Tanjong Pagar.
Hong Kong has one practical advantage that the numbers do not capture: neighbourhood variety. Moving from Central to Sai Wan, Tseung Kwan O, or Tung Chung can cut rent by 30 to 40 percent while staying on a direct metro line to the business district. Singapore offers similar savings by moving to Jurong East or Tampines, but the rental spread between prime and suburban is narrower.

Food and Dining
Both cities are famous for affordable street-level eating, and this is where the comparison gets interesting.
Hong Kong’s cha chaan tengs serve a full set meal (rice, meat, soup, and a drink) for HK$45 to HK$65 (US$6 to $8). Dai pai dongs and cooked food centres offer similar value. Hong Kong’s food culture runs deep, and eating cheaply without sacrificing quality is genuinely easy.
Singapore’s hawker centres are arguably even cheaper. A plate of chicken rice or a bowl of laksa at a hawker stall costs S$4 to S$7 (US$3 to $5). The Singapore government actively subsidises and preserves hawker culture, and the variety is extraordinary.
At the mid-range restaurant level, the two cities are almost identical. A dinner for two at a mid-range restaurant costs around US$60 in both cities. Groceries are broadly comparable, with one notable exception: alcohol is dramatically cheaper in Hong Kong. A half-litre of domestic beer costs around US$1.70 in Hong Kong compared to US$4.50 in Singapore, a difference of more than 60 percent, driven by Singapore’s steep excise duties on alcohol.
| Category | Singapore (USD) | Hong Kong (USD) |
| Hawker/cha chaan teng meal | 3 to 5 | 6 to 8 |
| Mid-range dinner (2 people) | 60 | 61 |
| Milk (1 litre) | 2.90 | 2.80 |
| Dozen eggs | 3.40 | 3.15 |
| Domestic beer (0.5L store) | 4.50 | 1.70 |
Transport
Both cities have world-class metro systems that make car ownership unnecessary for most expats.
Hong Kong’s MTR and Singapore’s MRT are both clean, reliable, and extensive. A monthly transport pass in Hong Kong costs around HK$700 (US$90), while Singapore’s monthly pass runs about S$128 (US$96). The difference is modest. Taxis in Hong Kong are cheaper per kilometre, but Singapore’s Grab rides are reasonably priced and widely used.
The real divergence is in car ownership. In Singapore, buying a car requires a Certificate of Entitlement (COE) that currently costs upwards of S$100,000 (US$75,000) just for the right to own a vehicle for ten years, before you even buy the car itself. Hong Kong’s first registration tax is steep (up to 115 percent of the vehicle value), but the total cost of car ownership is still significantly lower than in Singapore. In practice, fewer than 10 percent of households in either city own a car, and most expats do not need one.
Tax: Hong Kong’s Biggest Advantage
This is where Hong Kong pulls decisively ahead, and for high-earning expats, the tax difference alone can offset higher costs in other categories.
Hong Kong operates a territorial tax system. Only income earned in or derived from Hong Kong is taxable. The progressive rates run from 2 to 17 percent, but most taxpayers pay the standard rate of 15 percent on the first HK$5 million of net income (16 percent above that). There is no capital gains tax, no GST, and no VAT.
Singapore’s progressive income tax runs from 0 to 24 percent. The top rate applies to income above S$1,000,000. On top of that, Singapore levies a 9 percent Goods and Services Tax (GST) on most purchases, which adds up significantly over a year of daily spending.
For an expat earning US$150,000 per year, the effective tax rate in Hong Kong is typically around 12 to 14 percent. The same income in Singapore would attract approximately 15 to 18 percent in income tax plus the ongoing impact of 9 percent GST on spending. On US$200,000, the gap widens further. Over a full year, Hong Kong typically leaves US$10,000 to US$15,000 more in your pocket than Singapore at the same gross salary.
Healthcare
Both cities offer excellent healthcare systems with a mix of public and private options.
Hong Kong’s public hospitals and clinics, run by the Hospital Authority, charge subsidised rates. An Accident and Emergency visit costs HK$400 (US$51), with critical and emergency cases exempt. A general outpatient appointment at a public clinic costs HK$150 (US$19). Wait times for non-urgent public care can be long, which is why most expats carry private insurance.
Singapore’s public polyclinics charge S$12 to S$20 (US$9 to $15) for subsidised citizens and permanent residents, but non-resident expats pay unsubsidised rates that are higher. Most expats in Singapore rely on employer-provided or private insurance.
Private healthcare costs are similar in both cities. A consultation with a general practitioner in private practice costs US$60 to US$120 in either city. Comprehensive expat health insurance runs US$200 to US$400 per month for an individual, depending on coverage level and provider.
Education and International Schools
International school fees are a major expense for expat families in both cities, and neither offers a clear advantage.
In Hong Kong, annual tuition at international schools ranges from approximately HK$100,000 to HK$290,000 (US$13,000 to US$37,000), with an average across all private international schools of around HK$178,000 (US$23,000). Many Hong Kong schools also require a debenture, a one-time payment of HK$50,000 to HK$500,000 that may or may not be refundable depending on the school.
In Singapore, international school fees range from approximately S$20,000 to S$50,000 (US$15,000 to US$38,000) per year. Debentures are less common in Singapore, though some schools charge registration and development fees.
Both cities have long waitlists for the most popular international schools. Applying early, ideally 12 to 18 months before entry, is standard advice in both Hong Kong and Singapore.
The Bottom Line: Side-by-Side Summary
| Category | Cheaper City | Typical Saving |
| Rent (1-bed, centre) | Hong Kong | 15 to 20% |
| Street food | Singapore | 30 to 40% |
| Mid-range dining | Tied | ~0% |
| Groceries | Tied | ~0% |
| Alcohol | Hong Kong | 60%+ |
| Monthly transport | Hong Kong | 5 to 10% |
| Income tax | Hong Kong | Significant (esp. >US$150K) |
| GST/VAT | Hong Kong (none) | 9% saved on all spending |
| Healthcare (private) | Tied | ~0% |
| International schools | Tied | ~0% |
For most expats, Hong Kong is the slightly cheaper city overall. The combination of lower rent, lower tax, and zero GST gives Hong Kong a meaningful cost advantage, especially for higher earners. Singapore’s edge in hawker centre dining and its slightly lower utility costs do not fully offset the tax and rent differences.
The deciding factor is usually salary and tax. An expat earning US$150,000 or more in Hong Kong will almost certainly retain more after-tax income than in Singapore. For lower earners, the gap narrows and lifestyle preferences (food culture, climate, proximity to Southeast Asia vs mainland China) become more important than pure cost.
Frequently Asked Questions
Which city is cheaper for a single expat?
Hong Kong is generally cheaper for a single expat, primarily due to lower rent and lower income tax. A single professional earning US$100,000 to US$200,000 can expect to save 10 to 15 percent more of their salary in Hong Kong than in Singapore, assuming similar lifestyles.
Is Singapore or Hong Kong better for expat families?
Both cities are excellent for families. Singapore is often cited as having a slightly more family-friendly environment (green spaces, lower density, less air pollution), but Hong Kong offers more affordable domestic helper arrangements (minimum wage HK$5,100/month vs S$600+/month in Singapore, though Singapore helpers live in and the comparison is complex). Education costs are similar.
Does the tax difference really matter?
Yes, significantly. On a gross salary of US$200,000, the difference in take-home pay between Hong Kong and Singapore can reach US$10,000 to US$15,000 per year. Over a three to five year posting, that difference compounds to a meaningful sum. Hong Kong’s zero GST amplifies the effect further.
What about the cost of domestic helpers?
Hong Kong’s statutory minimum wage for foreign domestic helpers is HK$5,100 per month (approximately US$654), plus accommodation, food, and return airfare. The total cost is typically HK$6,000 to HK$8,000 per month including food allowance. In Singapore, the minimum salary is S$600 per month, but employers also pay a monthly foreign worker levy of S$300 to S$450 and other costs. The total cost is broadly similar in both cities.
