Each line’s change in price is SingStat’s index for it, September 2025 to September 2026 (the table under “Your spending, line by line”). What your spending would have cost a year ago is each amount × the index then ÷ the index now, added up: $4,230. Your inflation: $4,321 ÷ $4,230 − 1 = 2.15%. The headline rate, worked out the same way from SingStat’s basket, is 2.20%; the points beside each reason add up to the difference. Your home’s rent value (imputed rent) is left out, as SingStat leaves it out of its “all items less imputed rentals” index.
Put in what your household spends in a month on each. They start at the average for your kind of household, so the closer they are to your own, the closer the rate. Leave out savings, loan repayments, CPF and income tax: they are not prices of things you buy.
