How do I calculate my budget?

Start with your monthly take-home pay (after taxes and deductions). Allocate 50% to needs (housing, food, insurance, transportation, minimum debt payments), 30% to wants (dining out, entertainment, shopping), and 20% to savings and extra debt payments. Adjust based on your cost of living — in expensive cities, needs may take 60%, while in affordable areas, you can save 30%+.

What percentage of income should go to housing?

The standard guideline is no more than 28-30% of gross income (or 35% of take-home pay) on housing. However, in high-cost cities, many Americans spend 40-50%. If your housing exceeds 35% of take-home, you'll need to cut other categories to maintain savings. If it exceeds 50%, consider downsizing, getting a roommate, or relocating.
