Frequently Asked Questions

What is the 50/30/20 budget rule?

The 50/30/20 rule is a simple budgeting framework: allocate 50% of after-tax income to needs (rent, food, bills), 30% to wants (entertainment, dining out), and 20% to savings and debt repayment.

Is 50/30/20 suitable for Vietnamese salaries?

Yes, but you may need to adjust. In major cities like Hanoi or Ho Chi Minh City, housing costs can push needs above 50%. Consider a 60/20/20 split if your rent is high relative to your income.

What counts as a 'need' vs a 'want'?

Needs are expenses you cannot avoid: rent, groceries, electricity, water, internet for work, and minimum debt payments. Wants are discretionary: coffee shops, streaming services, new clothes beyond basics, and dining out.
