Monthly expenses

The 50/30/20 budget rule

The 50/30/20 rule is a simple starting point for splitting your take-home pay:

Tag each expense above as a need, want or savings, and the calculator compares your actual split with those targets. It's a guideline, not a rule: in high-cost areas needs often take more than half, which is fine as long as you're still saving something every month.

Worked example

With $5,000 a month in take-home pay and the sample expenses above, needs come to $2,940 (58.8%), wants to $645 (12.9%) and savings to $700 (14%), leaving $715 unassigned. Needs are above the 50% target — common where housing is expensive — but there's room to fix the shortfall in savings: moving $300 of the unassigned money into savings would bring it to exactly 20%.

Frequently asked questions

Should I budget from gross or take-home pay?

Take-home pay — the amount that actually reaches your account after taxes and deductions. If retirement contributions come out of your paycheck before you see it, you can count them toward your 20% savings by adding them both to your income and as a savings line.

Is debt repayment a need or savings?

Minimum payments are needs, because you have to make them. Anything you pay above the minimum counts as savings, since it improves your net worth just as saving does.

How big should my emergency fund be?

The usual target is three to six months of essential expenses — your "needs" total. With the sample budget's $2,940 of needs, that's roughly $8,800 to $17,600. If that feels out of reach, a starter fund of $1,000 covers most small emergencies.

My income changes from month to month. How do I budget?

Budget on your lowest typical month so your essentials are always covered, and decide in advance what happens to extra income in good months — for example, half to savings and half to wants.

What if my needs are more than 50%?

Then adjust the split rather than abandoning the plan. A 60/20/20 or 70/20/10 budget is still a budget. The parts that matter most are spending less than you earn and saving something every month.
