How does this budget calculator work?

A budget is a plan for your money. Type in your take-home pay, then what you spend on needs, wants and savings. The calculator adds it up. It shows what is left each month and your split by percent. It also sets you next to the 50/30/20 rule and the average US household.

  1. Enter your pay and how often you get it.
  2. Fill in what you spend on each line. Add or remove lines to fit your life.
  3. Pick a rule, like 50/30/20, or set your own split.
  4. Read the result. It shows what is left and how far each group is from its target.

The math is one subtraction.

L=M−(N+W+S)L = M - (N + W + S)

In words: Start with your pay. Take away needs, wants and savings. What is left is yours to plan.

LL
what is left over
MM
your take-home pay for one month
NN
needs for one month
WW
wants for one month
SS
savings and debt payoff for one month

To turn a group into a percent, divide it by your pay.

share=BM×100\text{share} = \frac{B}{M} \times 100

In words: Divide a group by your pay. Multiply by 100 to get a percent.

BB
one group’s total (needs, wants or savings)
MM
your take-home pay for one month

Here is the example the page opens with. The numbers are made up.

GroupA monthShare of pay50/30/20 targetGap

Wants$90018%$1,500$600 under
Savings and debt payoff$70014%$1,000$300 short
Left over$3006%

Take-home pay is the money that lands in your bank account. Taxes and other paycheck deductions are already gone. Some guides call it net income. One guide is from the Consumer Financial Protection Bureau, which we will call the CFPB.

Three things this page does not do:

  • It does not work out your taxes. You type your own pay.
  • Nothing earns interest here. It is plain adding and taking away.
  • It is not advice. It shows your numbers next to common guides.

A budget tracks money coming in and going out each month. Net worth is a different number. It is what you own minus what you owe.

Add up what you own and owe with the net worth calculator →

How do I make a budget?

To make a budget, add up the money you bring home each month. Then list what you spend. Take the spending away from the pay. If the answer is above zero, you have money left to save. If it is below zero, you spend more than you make.

  1. Find your take-home pay for a month. Look at your pay stubs or bank deposits.
  2. List your bills and the day each one is due.
  3. Track what you spend for one month. Small buys count too.
  4. Sort each cost into needs, wants or savings.
  5. Check what is left. Then move money between lines until the plan fits.

The CFPB gives away tools for these steps in its Your Money, Your Goals toolkit:

  • An income and benefits tracker
  • A spending tracker
  • A bill calendar
  • A cash flow budget

Some costs stay the same each month, like rent. These are fixed costs. Others change, like food and gas. Many people use the average of the last few months for those.

Some bills come once a year, like car insurance. Divide the bill by 12 and set that much aside each month. In the calculator, switch the line to a year and it divides for you.

What is the 50/30/20 rule?

The 50/30/20 rule splits your take-home pay three ways. Half goes to needs, like rent and food. Thirty percent goes to wants, like eating out. Twenty percent goes to savings and paying down debt. On $5,000 a month, that is $2,500, $1,500 and $1,000. It is a guide, not a law.

N=0.50×M,W=0.30×M,S=0.20×MN = 0.50 \times M, \quad W = 0.30 \times M, \quad S = 0.20 \times M

In words: Half of your pay for needs. Three tenths for wants. Two tenths for savings.

NN
needs for one month
WW
wants for one month
SS
savings and debt payoff for one month
MM
your take-home pay for one month

The CFPB teaches this rule in its lessons on budgets. Its guide uses net income, which is your take-home pay. It also calls the rule only one rule to live by. Not everyone can follow it.

The table shows the split at seven pay levels. The pay amounts are examples.

Take-home pay a monthNeeds 50%Wants 30%Savings 20%
$2,000$1,000$600$400
$3,000$1,500$900$600

$8,000$4,000$2,400$1,600
$10,000$5,000$3,000$2,000

To see how far you are from a target, take the target away from what you spend.

gap=B−r×M\text{gap} = B - r \times M

In words: Take the group’s target away from what you spend on it. Above zero means over.

BB
one group’s total (needs, wants or savings)
rr
the rule’s share for that group, as a decimal
MM
your take-home pay for one month

Is it a need or a want?

A need is something you must pay to live and work. Rent, food, power and a ride to work are needs. So is the smallest payment on each debt. A want is anything you could skip, like eating out or a trip. Some things are both. You choose the group.

The CFPB guide lists rent, food, power and rides as needs. It lists dining out, trips and fun as wants. It puts emergency savings and paying down debt with savings.

In the calculator, each line has a group switch. Move a line and the split updates at once.

Budget percentages by category: what the average US household spends

There is no one right set of budget percentages. Here is what US households really spent in 2025. Housing took 33.9% of spending, transportation 16.5% and food 13.0%. The numbers come from the Bureau of Labor Statistics (BLS). They are averages, not targets. Your own split can look very different.

CategoryA yearA monthShare
Housing$27,790$2,31633.9%
Transportation$13,492$1,12416.5%
Food$10,633$88613.0%
Personal insurance and pensions$10,175$84812.4%
Healthcare$6,470$5397.9%
Entertainment$4,084$3405.0%
Cash contributions$2,237$1862.7%
Apparel and services$2,010$1682.5%
Education$1,583$1321.9%
Miscellaneous$1,335$1111.6%
Personal care$986$821.2%
Alcoholic beverages$630$530.8%
Tobacco$365$300.4%
Reading$114$100.1%
All spending$81,905$6,825100%

Housing and transportation are the top two rows. Together they took 50.4% of spending. Add groceries and health, and the four took 66.2%. That was 48.9% of the average income before taxes.

BLS counts consumer units. A consumer unit is close to a household. It can be a family, one person living alone, or people who share their main costs.

One BLS line holds Social Security and pension money. That money often leaves your pay before you see it. So the calculator skips that line when it sets you next to the average.

BLS also leaves out the part of a home loan payment that pays down the loan. So a home owner may see a higher housing share here than the average shows.

Does the 50/30/20 rule work at every income?

No. The rule fits some incomes better than others. In 2025, the lowest-earning fifth of US households spent $37,935 on average. Their average income before taxes was $18,125. The top fifth spent $159,512 and earned $286,188. When pay is low, needs can take far more than half of it.

HouseholdsIncome before taxesSpendingSpending as a share of income
Lowest fifth$18,125$37,935209%
Second fifth (from $32,623)$46,080$51,405112%

Highest fifth (from $160,635)$286,188$159,51256%
All$110,847$81,90574%
  • These are averages. They do not show a typical family.
  • Income here is before taxes.
  • Spending can pass income when people use savings, borrow or get help.

Is your needs share above the rule? This formula shows the pay at which your needs would fit.

M∗=NrNM^{*} = \frac{N}{r_N}

In words: Divide your needs by the rule’s share for needs. That is the pay at which they fit.

M∗M^{*}
the take-home pay needed
NN
needs for one month
rNr_N
the rule’s share for needs (0.50 in the 50/30/20 rule)

In the example at the top, needs are $3,100. They would be half of a take-home pay of $6,200. The calculator also has a 60/30/10 rule and a custom split.

50/30/20 vs 70/20/10, 60/30/10, 80/20 and zero-based budgets

Other budget rules change the three numbers. The 60/30/10 rule gives needs more room and saves 10%. The 70/20/10 rule puts 70% to all spending, 20% to savings and 10% to debt or giving. The 80/20 rule saves 20% first. In a zero-based budget, each dollar gets a line. None is left over.

Here is each rule on $5,000 of take-home pay a month.

RuleSplitOn $5,000 a month
50/30/20needs, wants, savings$2,500 · $1,500 · $1,000

Zero-basedevery line, until $0 is leftpay − all lines = $0

Envelope budgeting is a hands-on way to keep to a plan. You put the cash for each group in its own envelope. When one is empty, you stop spending from it.

Pay yourself first means you move money to savings on payday, before you spend. No one rule is right for everyone.

How much should I spend on rent?

A common guide is to keep rent at or under 30% of your pay before taxes. On $60,000 a year, that is $1,500 a month. The number comes from housing policy. The US government calls a household cost-burdened when housing takes more than 30% of its income.

R=0.30×A12R = 0.30 \times \frac{A}{12}

In words: Divide your yearly pay before taxes by 12. Then take three tenths.

RR
monthly rent at the 30% line
AA
yearly pay before taxes
Pay before taxes, a yearA month30% line50% line
$40,000$3,333$1,000$1,667
$50,000$4,167$1,250$2,083
$60,000$5,000$1,500$2,500
$75,000$6,250$1,875$3,125
$100,000$8,333$2,500$4,167
$150,000$12,500$3,750$6,250

The 50% line is a second marker. Past that line, the term used is severely cost-burdened.

Some landlords ask for yearly pay of 40 times the rent. That is the same 30% line, since 12 ÷ 40 = 0.30. Others ask for monthly pay of 3 times the rent, which is 33.3%.

In 2023, 49.7% of US renter households paid more than 30% of their income for housing. That was over 21 million households, the Census Bureau found.

Mind the base. The 30% line uses pay before taxes. The 50/30/20 rule uses take-home pay.

How much should I spend on groceries?

It depends on how many people you feed. In September 2026, the USDA’s Thrifty Food Plan cost $1,024 a month for a family of four. It is the cheapest of four USDA plans for healthy meals made at home. The average US household spent about $541 a month on groceries in 2025.

The USDA is the US Department of Agriculture. Its plans price a healthy diet at four cost levels.

HouseholdA month
One woman, 20 to 50$304.68
One man, 20 to 50$382.80
Two adults, 20 to 50$630.19
Family of four (children 6 to 8 and 9 to 11)$1,024.00

USDA prices each person as part of a family of four. For a smaller home it adds a bit. That is 20% for one person, 10% for two and 5% for three.

F=a×∑jcjF = a \times \sum_{j} c_j

In words: Add each person’s food cost. Then apply the USDA factor for your household size.

FF
the food cost for the household
cjc_j
one person’s monthly cost
aa
1.20 for one person, 1.10 for two, 1.05 for three, 1.00 for four

The Thrifty plan matters because it sets the top amount of SNAP. SNAP is the US program that helps people buy food.

The average household also spent $345 a month on eating out in 2025. So 39.0% of its food money went to meals out. These are averages from BLS, not targets.

How much should I save each month?

One common guide is to save 20% of your take-home pay. On $5,000 a month, that is $1,000. The country as a whole saves less. In September 2026, the US personal saving rate was 3.8%. Any amount helps. Saving 20% for one year sets aside enough to cover three months of spending.

That rate is from the Bureau of Economic Analysis, which adds up what all of us save. It is all personal saving as a share of all income after taxes.

s=SMs = \frac{S}{M}

In words: Divide what you save by your pay. That is your savings rate.

ss
your savings rate, as a decimal
SS
savings and debt payoff for one month
MM
your take-home pay for one month
m=12×s1−sm = \frac{12 \times s}{1 - s}

In words: This is how many months of spending one year of saving sets aside.

mm
months of spending
ss
savings rate as a decimal; the rest of your pay is spent

The table shows what one year of saving sets aside. It has no interest in it.

At the national 3.8% rate, a year of saving covers about 14 days of spending.

To see how long a cushion takes, use this formula.

t=k×ESt = \frac{k \times E}{S}

In words: Multiply your must-pay costs by the months you want covered. Divide by what you save a month.

The Federal Reserve asks adults about a surprise $400 bill. In 2025, 63% said they would pay it with cash or its equivalent.

Money set aside for surprise costs is called an emergency fund. This page stops at how much you set aside. Other pages pick up from there.

How do I budget when I am paid weekly or every two weeks?

Turn each paycheck into a monthly number. If you are paid every two weeks, multiply one check by 26 and divide by 12. A $2,000 check is $4,333 a month, not $4,000. In most years, two months bring a third check. Plan for those extra checks before they come.

M=P×n12M = P \times \frac{n}{12}

In words: Multiply one paycheck by how many you get in a year. Then divide by 12.

MM
your take-home pay for one month
PP

nn

Weekly524.33347.7%
Every two weeks262.16727.7%
Twice a month24200%
Monthly12100%

Say you get $2,000 every two weeks. That is $52,000 a year. A budget built on two checks a month plans for $48,000. The other $4,000 has no plan.

The calculator shows what to set aside from each check for every line.

Do you only know your pay before taxes? Take away the share that goes to taxes and deductions.

M=G×(1−t)M = G \times (1 - t)

In words: Take your pay before taxes. Take away the part that goes to taxes and deductions.

MM
your take-home pay for one month
GG

tt
the share taken out, as a decimal

The calculator does not work out that share. The box starts at a made-up 20%, so type your own. Your pay stub shows it. The IRS also has a free Tax Withholding Estimator.

Pay that changes from month to month is covered in the questions below.

What if I spend more than I make?

First, find the gap. Take your spending away from your take-home pay. Then look at wants, since they are the fastest to change. Next, check the big needs, like housing and your car. Small costs add up too. Five dollars a day is $1,825 a year.

Y=d×365Y = d \times 365

In words: Multiply a daily cost by 365 to see a year of it. For a weekly cost, use 52. For a monthly cost, use 12.

YY
the cost for one year
dd
the cost for one day
Repeat costA yearShare of $60,000 take-home pay
$3 a day$1,0951.8%
$5 a day$1,8253.0%
$10 a day$3,6506.1%
$25 a week$1,3002.2%
$50 a week$2,6004.3%
$15 a month$1800.3%
$50 a month$6001.0%

The what-if buttons under the result try three changes. They are rent up 5%, pay up 3% and wants down 10%.

Card debt can make the gap wider, since interest is added to what you owe. Investor.gov is a US government site for people who invest. It says no plan to invest pays off as well as clearing debt with a high rate.

See what a card balance costs with the APR calculator →

Prices move too. Take a budget of $4,000 a month at the end of 2020. It needed $4,976 at the end of 2025 to buy the same things.

Bnow=Bthen×∏y(1+iy)B_{\text{now}} = B_{\text{then}} \times \prod_{y}(1 + i_y)

In words: Raise the old budget by each year’s price change, one year after another.

These are past price changes from the Consumer Price Index. They are not a forecast.

Money you free up can go to savings. How it grows with interest is its own topic.

Questions people ask

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

Net income. That means your take-home pay, after taxes and other paycheck deductions. A teaching guide from the CFPB, a US consumer agency, says to make a budget with net income. Do you only know your pay before taxes? Switch the calculator to that mode and type the share taken out.

Does my 401(k) count toward the 20%?

Yes. In this tool, money you save to retire counts as savings. A 401(k) is a retirement plan at work. Its money often leaves your paycheck before you see it. If you budget from take-home pay, add that amount back to your pay first. Then list it under savings.

Are debt payments a need or savings?

Both. The smallest payment you must make on each debt is a need, because skipping it has a cost. Anything you pay on top of that goes with savings. That is the usual way to sort it. The CFPB’s guide lists paying down debt in the 20% group.

Can I use this as a budget template or spreadsheet?

Yes. Press Download CSV to save every line as a file. It opens in Excel, Google Sheets or any spreadsheet program. You can keep it as your own budget template. Press Print for a paper copy. Your pay, each line and the totals are all in it.

What is a zero-based budget?

It is a budget where pay minus planned spending and saving equals zero. Every dollar gets a line before the month starts. Nothing is left without a plan. Zero does not mean you spend it all. Savings is one of the lines. Pick Zero-based in the calculator to try it.

How often should I update my budget?

Check it each month, and redo it when your pay, rent or family changes. Prices move too. From the end of 2020 to the end of 2025, US consumer prices (CPI) rose about 24%. A $4,000 monthly budget from 2020 needed about $4,976 by then to buy the same things. That is past data, not a forecast.

How do I budget if my income changes every month?

Add up your take-home pay for the last 12 months and divide by 12. That is your average month. Some people plan their needs around their lowest month and save the extra in good months. The calculator’s Yearly pay option does the dividing for you.

Is this budget calculator free, and is my data saved?

Yes, it is free, with no sign-up. Your numbers stay in this page. We do not save them, and they never go into the link. Close the tab and they are gone. Print or download your budget if you want to keep it.
