About ToolSG

What ToolSG is, where its Singapore figures come from, and what the site is not.

ToolSG publishes free calculators and utilities for people in Singapore.

An independent website

ToolSG is not HDB, the CPF Board, IRAS, MOM, LTA, MOE, MAS, or any other government agency. A result on this site does not come from those agencies and does not replace their letters, portals, or calculators.

Where the figures come from

When a tool uses a Singapore rule or rate, the page names the agency, links to the page that was checked, and shows when that rule took effect and when it was last checked here. Live tools say when the upstream feed was cached. If a figure could not be confirmed from an official page, it is left as it was or marked as an example.

Who operates it

ToolSG is operated independently. This site does not publish a company registration number or a personal name for the operator.
