Might actually be even less than that:
The budget, which he says is after-tax money — meaning it’s $60,000 in take-home pay — is allocated like this: 50% on fixed expenses like mortgage and car payments; 30% on variable expenses like food and gas; 20% toward savings.
That sounds like $48,000/year. Or maybe the 20% savings means money he's saving up to enable bigger purchases on a less than monthly basis?
Either way, this seems like a very intelligent reaction to making an awful lot of money per year but with a short and unpredictable career length. Good for him.
