About The Singapore Calculator

The Singapore Calculator offers free calculators for the numbers Singapore residents deal with most: CPF, income tax, GST, stamp duty, housing loans, car loans, health measures, maths and unit conversions.

Each calculator shows its formula and a worked example, so you can see exactly how a result was reached. Figures are based on rates published by CPF Board, IRAS, HDB, MOM, LTA and MAS, and are reviewed when those rates change.
