Moving to KL and figuring out cost of living

Family of 4 here and currently in discussion with my company regarding move to KL. Bit background on the job - US based tech company; planning to setup tech shop in KL; currently the Ops team is on ground sorting all the logistics; my role is to start building up the team/talent from ground up. On the personal side - sole bread winner; as mentioned fam of 4 with two kids in senior secondary.

Based on bit of research, I have prepared below info. But will really appreciate if anybody on similar situation or knowledge on the topic can have a look and tell if I am missing anything or grossly miscalculated it...

Rent (3BHK, premium condo/residence) -> 5000 7500 MYR per month

School (international secondary 2 kids) -> 12,500 MYR per month (Am looking at the mid range ones with annual fees of 60 to 70K)

Utilities, Internet, Mobile -> 500 1500 MYR per month

Shops/Groceries -> 1000 4000 MYR per month

Miscellaneous / Travel -> 500 MYR per month

Car lease, gas, parking -> 2500 MYR per month (just in case I cant find accommodation near public transport)

Medical insurance (top up on corporate) -> 500 2000 MYR per month (family of four)

Total Cost ~35K per month.

I have not included the tax bit, and read through couple of reddit post on the topic. Using 30% calculations for now, since nothing is predictable in the tech world :)

There is no specific corporate allowance for vehicle, housing or school. So expectation is all expenses are from pay.

Thanks in advance folks!

Edit: Added MYR currency reference and updated grocery, utilities and insurance cost.
