Cost of Living in Greenwich CT 2026
What Families Actually Spend

Short answer: yes, Greenwich is expensive, and nearly all of it is the house. The August 2026 single-family median was $3.95 million. Property taxes push the other way: the FY2026-27 mill rate of 10.125 is the lowest in Connecticut, about $14,175 a year on a $2 million home. Add $314.25 a month for a Metro-North pass and whatever childcare costs you, and you have the four lines that decide a Greenwich budget.

When we left the Upper West Side for Greenwich, the first spreadsheet I built skipped schools and the commute and asked one question: what does this town actually cost once you stop pretending rent is the whole story?

Greenwich is expensive. You get more space, strong public schools, and a fastest scheduled ride of 44 minutes to Grand Central. Below are the numbers I wish someone had handed me before we bought: housing, taxes, train, childcare, and the line items people forget.

Housing is the biggest expense in Greenwich. The Greenwich Association of REALTORS reported an August 2026 single-family median of $3,950,000, up 41% from August 2025, with homes lasting 17 days on market and selling at 103.6% of list. Inventory sat at 83 active single-family listings. August also had only 37 closings, the fewest in any August since 2009, so the monthly median swings. For price bands, neighborhood medians, and what to expect this fall, see the Greenwich housing market update.

Condos are where buyers priced out of houses are going. August condo/co-op median was $1,162,500, and new condo listings nearly doubled year over year. Cos Cob is still the least expensive of the in-town neighborhoods, but its median through July was $2.4 million, up 20%, according to Greenwich MLS data from the Greenwich Streets Team. On September 1 only four single-family homes in all of Greenwich were listed under $1 million. Walkable Riverside and Old Greenwich family houses typically start closer to $1.8 million. Belle Haven and Backcountry remain a different universe.

Renting is not a cheap workaround. Three-bedroom listings around $3,800 a month are what you see when a family is testing the town for a year, which a lot of NYC movers should do. If you're buying, underwrite the tax bill on the new assessed value, not last year's.

Property taxes in Greenwich are based on a mill rate. For fiscal year 2026-27, that rate is 10.125 mills, the lowest in Connecticut, down from 12.041 after the 2025 revaluation, per the Town of Greenwich FY2026-27 Final Budget (adopted May 18, 2026). You pay $10.125 for every $1,000 of assessed value. Assessments are 70% of market.

On a $2 million home assessed at $1.4 million, the tax is about $14,175. That is the math on today's mill rate. It is not a promise your bill went down. Average residential assessments rose about 27%. If your neighborhood ran hotter than that, especially Old Greenwich, Riverside, or Cos Cob, the July bill can still be higher than last year.

Most Greenwich homeowners still budget $15,000 to $40,000 a year depending on the house. Those taxes fund the public schools, which is why a lot of families skip $40,000-a-year private tuition.

Basic utilities (electric, heat/cool, water, trash) usually land around $200 to $300 a month for a typical family house. Bigger places, older systems, and oil heat push that up. Internet runs about $60 to $100 depending on the plan.

The surprise for city movers is the yard. Landscaping and snow removal are real monthly or seasonal bills once you leave a doorman building. Older Greenwich houses also need roof, HVAC, and paint money on a schedule. If you are not handy, price that labor into the mortgage math.

Groceries run higher than most of Connecticut, roughly 10 to 20% above the national average if you shop organic and local. Milk around $5 a gallon and eggs around $4 a dozen are normal stickers, not holiday spikes.

Mid-range dinner out is usually $20 to $30 a person before drinks; fine dining clears $100 a person fast. Plenty of families live on pizza and casual spots during the week and treat Avenue dinners as the splurge, not the baseline.

Metro-North is the main way Greenwich commuters get to New York City. A monthly ticket between Greenwich and Grand Central is $314.25 after the July 1, 2026 fare increase, up from $294.75, per the Coastal Connecticut Times. Cos Cob, Riverside, and Old Greenwich are in the same fare zone, so the price is the same from all four stations.

The fastest scheduled weekday ride from Greenwich station to Grand Central is 44 minutes; the median is 58 minutes. Cos Cob, Riverside and Old Greenwich have different schedules. Include station parking and your final trip from Grand Central in both your time and money budget.

Train times: scheduled weekday rides on Wednesday, Oct 14, 2026, from the MTA Metro-North GTFS feed. Road miles: OpenStreetMap driving route between town halls, October 2026. Drive times swing with I-95 and Merritt traffic, so check a live map at the hour you'd travel.

Gas in Greenwich costs more than the national average. Parking adds up, especially if you drive into the city. Insurance and routine maintenance also run higher here, in line with the high cost of living.

Many families have two cars. That means two car payments, two insurance bills, and two sets of maintenance costs. If you didn't own a car in the city, this whole line item is new.

Care access is strong here. Premiums, specialist visits, and prescriptions carry Fairfield County prices, which are high. Employer coverage softens it. Private or marketplace plans sit on the expensive end of Connecticut.

Check dental and vision before you move. Those often sit outside the medical plan, and a family that was used to NYC network density should confirm who is in-network in Greenwich, not assume the same doctors transfer.

Public school is free once you live here, and for a lot of families that is the whole point of the tax bill. Start with the Greenwich schools guide. Private tuition still runs about $30,000 to $50,000+ a year when families want smaller classes or a specific program.

Childcare is another big expense, and it is the line item NYC families underestimate. If both parents commute, you need a 12-hour nanny or an au pair, not a 9-to-5 daycare, because several elementary schools start around 9am and sick-day pickup can be under an hour. Nanny rates commonly run $17 to $25+ per hour. Daycare is roughly $1,200 to $2,000 a month. Au pairs are often $20,000 to $25,000 a year plus room and board.

Many families mix part-time care, grandparents, or a nanny share. If only one parent is in the city, the math gets easier. If both are on a 7:45 train, budget for coverage before you budget for granite.

Greenwich Point Park and the town beaches are the free weekend plan a lot of families actually use. See things to do in Greenwich for the low-cost list.

Golf and yacht club dues run into the thousands a year. Theater tickets and Avenue shopping are optional, and easy to undercount if you treat them as "sometimes" instead of a line item.

Taxes in Greenwich CT

Greenwich's property tax rate is low, but Connecticut's state taxes are not. Residents pay state income tax. For 2026 it ranges from 2% to 6.99%, depending on your income bracket, per the Connecticut Department of Revenue Services. The top rate applies above $1 million of taxable income for married couples filing jointly.

Sales tax is 6.35%, same as the rest of the state.

Connecticut is one of the few states that has both an estate tax and a gift tax. If you're a high-net-worth family planning to stay in Greenwich long-term and pass assets to future generations, plan for both.

Greenwich has no local income tax. Nonresidents of New York City do not pay its resident personal income tax, but moving to Connecticut does not automatically eliminate New York State tax on New York-source earnings. Residency and remote-work rules matter; use the New York Department of Taxation and Finance guidance when comparing take-home income. Coming from the West Coast instead?
