What is the 50/30/20 budget rule?

It is a simple thumb rule for budgeting: spend 50% of your after-tax income on needs, 30% on wants, and 20% on savings or paying off debt.

What are fixed vs. variable expenses?

Fixed expenses remain the same every month (like rent or insurance), while variable expenses change based on usage or choice (like groceries or entertainment).
