Inflation Calculator for Bangkok

Prices paid by households in Bangkok follow the national consumer price index for Thailand, because official inflation is measured country-wide rather than city by city. In the latest month available, September 2026, annual consumer price inflation was 2.82% according to the Bank for International Settlements (BIS) series compiled from the national statistics office.

Worked example for Bangkok

Enter THB 20,000 as today's cost, 2.82% as the inflation rate and 10 years. If prices in Bangkok kept rising at that pace, the same basket would cost THB 26,412 in 2036, and THB 20,000 left in cash would buy only what THB 15,144 buys now. The figure of THB 20,000 is just an example amount in Thai baht; type your own rent, school fee or grocery bill instead.

The average of the ten calendar-year rates from 2016 to 2025 for Thailand works out at 1.1%. Try that figure as well as the latest 2.82% reading: the gap between the two shows how sensitive a long-range plan in Bangkok is to which rate you pick. For a 20-year horizon the difference between 1.1% and 2.82% changes the future cost of THB 20,000 from THB 24,685 to THB 34,880.
