What is the 50/30/20 rule?
It's a simple way to start a budget. Fifty percent of what you take home covers the things you must pay, thirty percent the things you choose, and twenty percent goes to savings and paying down debt.
When to change the numbers
If rent alone takes half of your income, the rule is a starting point, not a verdict. Move the split to fit your life, and pay off high-interest debt first.
Make it automatic
