About SG Calculators

SG Calculators is a small, independent collection of free calculators for everyday Singapore money, property, car, renovation and Pokemon card questions. It needs no sign-up and does not collect what you type.

How we check the numbers

• Every rate comes from an official source (CPF Board, IRAS, HDB, MAS, LTA) or, for card fees, the platform's or grader's own published page, linked on each calculator with the date it was checked.
• Each formula is written twice (the in-page calculator and a separate reference implementation) and the two are tested against each other and against the worked examples published by the agencies, such as IRAS's stamp duty and tax tables and CPF Board's contribution tables.
• We never invent prices, statistics or reviews. Where a figure is yours to decide (renovation quotes, card values, pull rates), the calculator says so and starts at zero or with a clearly labelled illustration.

How the site is funded

The calculators are free. Some pages link to related services connected to the site's owner, and the site may show advertising in future. See the disclosure page for details.

Corrections

Rates change. Pages are reviewed when agencies announce changes; the "rates as of" date on each page tells you when it was last checked. Official sources always take priority over this site.
