The 50/30/20 Budget

The idea

The 50/30/20 rule, popularised by a 2005 personal finance book, is a quick way to give every dollar a job without tracking every coffee. You take your after-tax income and aim to spend about half on needs, about 30 percent on wants and about 20 percent on savings and extra debt payments.

Needs are things you must pay to live and work: rent or mortgage, utilities, groceries, insurance, minimum loan payments and basic transport. Wants are everything else you enjoy: eating out, streaming, travel, new gadgets. Savings include an emergency fund, retirement contributions and paying debts down faster than the minimum.

A worked example

Say you take home 3,000 dollars a month. The rule suggests about 1,500 dollars for needs, 900 dollars for wants and 600 dollars for savings and debt. If your rent alone is 1,400 dollars, needs will run over 50 percent, and that is normal in high-cost cities. In that case you might use 60/20/20 or 60/30/10 for a while, and look for ways to bring fixed costs down over time.

Making it stick

Automate the savings part. Many people set up a transfer to a separate savings account on payday, so the 20 percent leaves before it can be spent. Use your bank app or a simple spreadsheet to check the split once a month rather than every day. Review subscriptions twice a year; small recurring charges are the easiest wants to forget.

When to use something else

If you are paying off high-interest credit cards, you may want to push more than 20 percent toward debt until it is gone; see our debt payoff guide. If your income changes a lot month to month, a zero-based budget, where you plan every dollar each month, can work better. The best budget is the one you will actually follow.
