Budget Calculator: The 50/30/20 Rule

What counts as a need, a want and savings

• Needs (50%): rent or mortgage, utilities, groceries, insurance, transport to work, childcare, and minimum payments on debts.
• Wants (30%): eating out, streaming and subscriptions, travel, hobbies, upgrades beyond the basics, such as a bigger apartment or newer car.
• Savings and debt (20%): emergency fund, retirement, investing, and any debt payments above the minimum.

Example: $4,500 a month take-home

The rule suggests $2,250 for needs, $1,350 for wants and $900 for savings. If you currently spend $2,600 on needs, $1,300 on wants and save $600, needs are $350 over target and savings are $300 short. Moving $300 from wants to savings, and looking at the biggest need (usually housing or a car payment) when it comes up for renewal, gets you on track.

Making a budget stick

• Pay yourself first: automate the savings transfer on payday.
• Track spending for one month before changing anything, so you know your real numbers.
• Review subscriptions every few months; they add up quietly.
• Give every category a little slack. Budgets that are too tight get abandoned.

Frequently asked questions

What is the 50/30/20 rule?

Spend about 50% of after-tax income on needs (housing, food, utilities, insurance, minimum debt payments), 30% on wants, and put 20% toward savings and extra debt payments. It was popularized by Senator Elizabeth Warren in the book All Your Worth.

Is 50/30/20 realistic in an expensive city?

Often not: housing alone can take 40% of pay. Many people use 60/20/20 or 70/20/10 instead. The point is to set a savings amount first and keep needs from crowding it out.

Should I budget from gross or net pay?

Net pay, what lands in your bank account. If you already save through a 401(k) at work, count that toward the 20%.
