How much do you all spend on living expenses?

I am in my early 50s and the sole breadwinner. I earn about 8 million KRW after tax. I have two daughters—one is a college student and the other is preparing for employment—but why does the budget always fall short? Even though my company provides a vehicle and fuel support, there is always a deficit at home. I don't receive an allowance separately, and we own our home, so how much do you all typically spend? Just venting for a moment. Hang in there with these high prices.
