50/30/20 Budget Calculator: Split Your Take-Home Pay

The 50/30/20 rule splits your take-home pay three ways: half for needs, 30% for wants and 20% for savings and paying off debt. On $5,000 a month after tax, that means $2,500 for needs, $1,500 for wants and $1,000 for savings, or $12,000 saved a year. Change the percentages to fit your situation and see the amounts per month, per year and per paycheck.

What goes in each bucket

• Needs (50%): costs you can’t easily avoid, such as rent or mortgage, utilities, groceries, insurance, transportation to work, childcare and the minimum payments on your debts.
• Wants (30%): things that make life better but you could cut, such as eating out, streaming services, travel, hobbies, new clothes beyond the basics and upgrades like a nicer car or phone.
• Savings and debt (20%): an emergency fund, retirement savings, investing, saving for a goal, and any debt payments above the minimum.

The rule was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth. It works from take-home pay, the money that actually reaches your bank account, not your salary before tax.

Turning a paycheck into a monthly budget

If you’re paid every two weeks you get 26 paychecks a year, which averages 2.17 a month. A $2,400 paycheck every two weeks is $5,200 a month on average, so the 50/30/20 split is $2,600, $1,560 and $1,040, or $1,200, $720 and $480 from each paycheck. Two months a year bring a third paycheck; putting all of it into savings is an easy way to beat the 20% target. Weekly pay works the same way with 52 paychecks.

When to change the percentages

• High housing costs: in expensive areas rent alone can take 40% of pay. A 60/20/20 split keeps savings at 20% by cutting wants.
• Paying off debt fast: moving to 50/20/30 sends an extra 10% of pay to debt and savings.
• Low income: needs may take 70% or more at first. Start with whatever you can save, even 5% to 10%, and raise it as income grows.
• Saving through payroll: 401(k) contributions taken out before your pay arrives are already savings. Add them back to see your full savings rate.

Enter what you actually spend on needs each month, and the calculator shows how far it is from your target. On $5,000 of take-home pay, needs of $2,900 are 58.0% of pay, $400 over a 50% target.

FAQ

Is the 50/30/20 rule based on gross or net income?

Net income: what’s left after federal and state income tax, Social Security, Medicare and other payroll deductions. If your employer takes out health insurance or retirement contributions, your take-home pay is already lower by those amounts.

Do debt payments count as needs or savings?

The required minimum payments are needs. Anything you pay above the minimum to clear debt faster comes out of the 20% savings bucket.

What if my needs are more than 50%?

That’s common, especially with high rent or childcare costs. Take the extra from wants first so savings don’t suffer, and look at the biggest fixed costs, such as housing, car payments and insurance, for lasting savings.

Is 50/30/20 the best budget?

It’s a simple starting point rather than a strict rule. If you like more detail, a zero-based budget gives every dollar a job; if you prefer less, just automate the 20% to savings on payday and spend the rest freely.
