Are the lower-income living in larger HDB flats, necessarily better off?

HDB Why no breakdown of the cost components (69)
Expenditure exceeds take-home pay by 32 to 76%?
Household expenditure of those who were in the 1st – 20th income percentile living in 1/2-room – $1,098 vs their income of $1,220
However, since the income is including employer CPF – the typical net take-home pay may be about $834 (less CPF)
So, their expenditure may actually exceed their take-home pay by about 32% ($1,098 divided by $834)
Similarly, for HDB 3-room – $1,598 expenditure vs $1,700 income =
expenditure may actually exceed their take-home pay by about 38% ($1,598 divided by $1,162)
For HDB 4-room – $2,667 expenditure vs $2,697 income =
expenditure may actually exceed their take-home pay by about 45% ($2,667 divided by $1,844)
For HDB 5-room and executive flats – $3,132 expenditure vs $2,601 income = expenditure may actually exceed their take-home pay by about 76% ($3,132 divided by $1,778)
The above may mean that most may not have much if any money left for savings
Does it mean that about 300,000 households or about 1 million people may be struggling to make ends meet, or have hardly any money left to save?
