Engineering

Local context: Singapore parameters

Singapore's rules are unusually flat and predictable, and Engineering reflects that structure directly.

Key local facts

• Currency: Singapore dollars, S$1,234.56. GST is currently 9% and shown inclusive on most consumer prices.
• Income tax: Progressive resident rates from 0% up to 24%, with no capital gains tax and no inheritance tax.
• CPF: Mandatory CPF contributions from both employer and employee, split across Ordinary, Special and MediSave accounts by age band.
• Units: Metric — km, kg, °C, litres — with residential space quoted in square feet despite the metric norm.
• Power: 230 V / 50 Hz with Type G plugs, and installations follow SS 638.

Local examples

• Example — CBD: An employee in the CBD uses Engineering to separate CPF from take-home pay before budgeting.
• Example — HDB resale: A buyer checks an HDB resale figure with Engineering, keeping stamp duty as a separate calculation.

Every figure above applies to Singapore specifically and is reviewed when the rules change.
