Below is roughly the expenses every month for the three of us (married with one newborn). Both of us are working, and we are still young (between 25 and 30). It's quite detailed because we keep track of our expenses every month for over a year already.

Rent: RM800 (single storey terrace house in Seri Kembangan; this will increase to RM900 next year)
Car Loan: RM700 (2014 Proton Preve Exec, which my wife bought before I even knew her, so don't judge me )
Eating Out: RM400 (quite low because we bring lunchbox almost everyday)
Groceries: RM400 (including non-food items like shampoo, tissue, etc.)
Petrol: RM400 (our car's average fuel efficiency is 9.3 l/100km, so this translates to roughly 2100km per month)
Toll: RM100
Clothing/Appliances/Furnitures: RM50 – RM100 (once every 2 – 3 months)
Parking: RM10 (mostly for parking in shopping malls)
Service charge: RM10 (misc charges, such as RM0.53 charged when doing instant transfer)
Giving/Gifts: RM100 – RM150 (occasional donations to charity, buying friends/relatives small gifts, etc.)
Movies: RM30 (we watch one movie every month, and we usually take advantage of promotion from CC)
TNB: RM50 – RM70
Internet: RM187 (Unifi 50mbps)
Phone bill: RM100 (Umobile P70 + Share 20)
Software subscriptions: RM37.99 (Office 365 for my whole family)
Parents: RM1,165 (We give RM250 to each parent, and help my wife's parents pay their Unifi 10mbps bill)
Siblings: RM200 (We give our non-working siblings RM50 each)
Health + Life insurance: RM484
Blow money: RM50 – RM100 (this is my wife's off-budget money)
PTPTN: RM400
Mortgage: RM450++ (partial payment for our undercon apartment)
Child: RM500 – RM700 (newborn; mostly for diapers and nursery)
IWK saving: RM8 (RM25.44 every 3 months)
Auto insurance + road tax saving: RM75 (roughly RM900 every year)
Car maintenance saving: RM170 (for minor service, major service, change battery, and change tyres)
Vacation saving: RM100 – RM150 (we go on a budget vacation every 3 – 4 months)

There are still areas for improvement which we will work on over time:

- Our health and life insurance is overpriced. I'm planning to switch to standalone health insurance + term life insurance, instead of the current whole life insurance with health insurance as riders. We can probably shave RM200 by doing so, and we will be investing the difference.
- Our car loan is quite expensive. Not much we can do but continue paying it. Still 6 years to go. After it is paid off, we will never purchase another new car. We will only purchase second hand car with cash.
- Petrol and toll can be reduced. Currently I travel 70km to and from work everyday. I probably can cut this down by renting near my workplace, or get a remote job.
- Phone bill can be reduced further by RM20 – RM30 by switching to Umobile P38/P48 + P28. Our current plan is overkill, as we usually end up using less than 50% of our quota. However, my wife requires a plan with unlimited call, so Umobile is the cheapest, hence why we're with Umobile.
- PTPTN will be paid off in 6 years. It's under my wife's name, and it's already in CCRIS because she did not pay for it before we got married. It's a good thing because that prevents her from asking me to bring her to vacation overseas.
- We are currently paying for both rent and mortgage partial payment, which sucks. Not much we can do other than suck it up until end of 2018.
