Price (THB)฿10M

Interior area

sqm

Common-area fee (THB per sqm a month)

Your building's figure, charged on the interior area whether the home is let or empty. A villa estate may charge a monthly fee instead: enter it as THB per sqm.

Land and building tax

How you hold it

A second home is taxed from the first baht, from 0.02% of appraised value. Monthly lets stay residential; nightly paid stays fall outside residential use and may be assessed at higher rates.

Advanced: appraised value

Appraised value, share of price฿8M

The tax is charged on the official appraised value, usually below the price paid. Your assessment notice gives the figure. 80% is a working assumption, not a rule.

Your own yearly costs

Insurance (THB a year)

Contents and liability cover. The building's policy covers the structure, not your belongings.

Utilities and internet (THB a year)

Including what runs while you are away: a fridge, dehumidifiers, internet.

Care and repairs (THB a year)

Inspections, cleaning, air-conditioning service, small repairs.

Reserve for replacements (THB a year)

Furniture and appliances wear out faster by the sea, and co-owners can vote further sinking fund calls.

Budget ฿59,900 a year to keep the home, before any rent. Add your own insurance, utilities and upkeep for the full figure.

Land and building tax is charged on each slice of appraised value at its own rate. The local authority sends the assessment by the end of February and payment is normally due by the end of April. Common-area fees paid late carry interest of 10% a year, and 20% more once six months overdue, under the Condominium Act. An estimate from your figures, not tax advice: see running costs explained.

The method

How the running cost calculator works

The common-area fee is the building's rate per square metre a month on the interior area, charged whether the home is let or empty. Start from a development's published fee or enter your building's.
Land and building tax is worked out band by band on the appraised value: from 0.02% for a second home, with the first THB 10 million exempt on a registered main home held without the land.
Insurance, utilities, care and a reserve for replacements are your own figures.
If you let the home, the rent is reduced by the management share and by tax: 15% withholding for a non-resident, or a resident's own rate after a 30% deduction.

Questions

Running cost calculator: questions it answers

How much does it cost to own a condo in Thailand each year?

The common-area fee is usually the largest line: the building's rate per square metre a month on the interior area. Add land and building tax, which is small on most homes, then insurance, utilities and upkeep. The calculator adds them on your figures.

How much is land and building tax on a Thai condominium?

A home that is not your registered main home is taxed from 0.02% of the appraised value up to THB 50 million, rising in bands to 0.1% above THB 100 million. On an appraised value of THB 8 million that is THB 1,600 a year.

What happens if I pay the common-area fee late?

Under the Condominium Act, overdue common charges carry interest of 10% a year, a further 20% once more than six months overdue, and the building's regulations may restrict utilities or facilities. A sale cannot be registered until the building certifies that nothing is owed.
