Yeah that number is really high. I think 5-8k is what most people would spend.
You are viewing this as a parent of small children. I have an adult daughter, a teenager and a tweenager.
The teenager expenses:
Pocket money: R1K
2022 Schooling: R4K (public school)
Medical: R1K extra
Food: R1500 (they eat a lot)
Clothes: R1K per month (we pay cash and he is cheap)
Entertainment: R500 is what he adds to our monthly bill.
Sport: R500
That's R9500 every month but I still need to add:
* Extra life insurance I had to take out to cover his schooling if something happens to me.
* Educational incidentals as I like to call it, all the hey-dad-I-need-this-for-a-project expenses.
* Family entertainment, even camping can add R1K per child for a long weekend.
* Petrol for random driving around.
* Presents
* etc etc
That surplus R2500 get's consumed very quickly.
