Inflation calculator Hong Kong
Prices change over time, so $1,000 in one year doesn't buy the same as $1,000 years later.
This calculator uses the Composite CPI, the index the Census and Statistics Department uses to reflect inflation for households as a whole.
How it's calculated
- Find the Composite CPI for the month of the original amount and for the month you want to bring it to.
- Multiply the amount by the end index and divide by the start index.
- The latest index published is 111.2, for 1 September 2026. A later date stops at that month.
An example
$1,000 in August 2025 is worth $1,016.51 in August 2026, using a Composite CPI of 109.0 and 110.8.
