I've been tracking my spending for two years with a simple spreadsheet, and I'm still not sure if the 50/30/20 rule makes sense for anyone who doesn't have a stable income. When my freelance checks vary from 2,000 to 6,000 a month, how do you budget for essentials when your 'fixed' costs change with the seasons? Maybe personal finance advice needs to stop pretending that any single formula works for every situation, but I also wonder if I'm just making excuses for poor discipline. What's your take — are percentage-based budgets actually useful, or do they fail most people in the gig economy?
