Lets compare an old person like me, to a youngster starting out.

Bond

Me: (almost paid up) R4000 (property value R1.8 million)

Youngster buying a property next door bond around R16000 for the next 25 years.

Then there is the R5000 utility bill and we will leave out the maintenance costs.

School fees:

Me: one kid with 1.5 years left to go, R4500 per month

Youngster: lets work on just 2, R9000 per month

Food bill:

Me: 3 people in the house (we splash out 1 or twice a month) R6000

Youngster: 4 people in the house around R7000

Vehicle:

Me: both vehicle are paid up.

Insurance: R1000... Cheaper because I am old.

Youngster: 2 vehicles (cheap) still being financed with a 50 residual, so they going to be paying for the next 6 years at least, R5000

Insurance R3000

Medical aid: R6000 for both
