Real estate calculators
The tools agents and home buyers use most, calculated at the rates and criteria actually used in Thailand. Every tool is free, no sign-up needed. Figures you enter are calculated on your own device and are not sent or stored anywhere.
Home loan capacity calculator
At this income, how many million can you borrow?
Based on income, debts and age by the criteria Thai banks actually use. Shows the loan amount, installment and down payment to prepare, and tests whether you can keep up if interest rises.
Best for People who don't yet know what price of home they can buy
Mortgage schedule + extra payment calculator
Pay this much extra a month - how much do you save?
Installment, total interest over the term and a yearly reducing-balance schedule - and the answer banks rarely give: how many years sooner you finish with extra payments.
Best for People already paying off a home
Land, house & condo transfer fee calculator
How much cash to prepare on transfer day?
Transfer fee, specific business tax, stamp duty and withholding tax, split to show what buyer and seller each pay. Supports sales, inheritance and gifts.
Best for People who have agreed on a sale
Land & building tax calculator
How much to pay this year?
Rates by type of use - residential, agricultural, commercial and vacant land - with step-by-step working so you can see what is exempt and what is taxed.
Best for Everyone who owns land or a house
Which one should I use first?
The first three follow the order of a real home purchase. Start with the loan capacity calculator to know your budget, then look at the mortgage schedule to see whether the monthly installment is affordable, and before transfer day check the transfer fee in advance, because it is a lump of cash not included in the loan and must be prepared separately - a point first-time buyers often forget until they reach the Land Office. The land tax is a different matter from the first three, because it isn't paid once at purchase but every year for as long as you own the property.
