50/30/20 budget calculator, per month and per paycheck
The 50/30/20 rule splits your take-home pay three ways: 50% for needs, 30% for wants, 20% for savings and extra debt payments. Enter what lands in your bank below to get the three amounts for a month and for each paycheck, then compare them with what you spend now.
| Per month | Per check | |
|---|---|---|
| Needs 50% | – | – |
| Wants 30% | – | – |
| Savings and debt 20% | – | – |
| Take-home | – | – |

How the 50/30/20 calculation works
The rule was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth. It works on after-tax income, so the math is three multiplications:
- Monthly take-home = take-home per check × checks a year ÷ 12. Biweekly: × 26 ÷ 12. Weekly: × 52 ÷ 12. Twice a month: × 2.
- Needs = monthly take-home × 0.50
- Wants = monthly take-home × 0.30
- Savings and debt = monthly take-home × 0.20
Example: $1,600 every two weeks is $1,600 × 26 ÷ 12 = $3,467 a month. Needs $1,733, wants $1,040, savings and debt $693. Per check: $800, $480 and $320.
Why per check matters: on biweekly pay, two months a year have three paychecks. A monthly 50/30/20 built on $3,467 quietly assumes some of those third checks. Splitting each check instead keeps every check balanced, and makes the third check easy to aim at savings. Our guide to budgeting biweekly paychecks shows the full method.
The same split on every pay schedule
Here's one take-home of about $3,467 a month, paid four different ways. The monthly amounts match; what changes is how much each check has to carry, and how many "extra" checks the year has.
| Paid | Take-home per check | Needs | Wants | Savings | Extra checks |
|---|---|---|---|---|---|
| Weekly | $800 | $400 | $240 | $160 | 4 or 5 five-check months a year |
| Biweekly | $1,600 | $800 | $480 | $320 | 2 three-check months a year |
| Twice a month | $1,733 | $867 | $520 | $347 | None |
| Monthly | $3,467 | $1,733 | $1,040 | $693 | None |
Weekly: rent usually can't come from one $400 needs share, so set aside a quarter of rent from each check into a separate pot. Our guide to budgeting weekly paychecks shows how.
Biweekly: pay each month's bills from its first two checks. In the two months with a third check, the whole check can go to savings and debt; two checks are nearly 8% of a year's pay, on top of the 20%. The 2027 dates are in 3 paycheck months in 2027.
Twice a month: the closest to a plain monthly budget. Put rent on the check before it's due, and spread the other big bills so each check's needs share comes out close.
Monthly: simple math, but a long wait. Move the savings share the day you're paid, and set a weekly spending limit for wants so the month's 30% isn't gone in the first week.
Use take-home pay, not salary
The rule splits money that reaches you. If you only know your salary, take off taxes first. A rough 2026 guide for a single person in a state with no income tax:
| Salary | Take-home per biweekly check | Needs per check | Wants per check | Savings per check |
|---|---|---|---|---|
| $35,000 | $1,165 | $583 | $350 | $233 |
| $45,000 | $1,475 | $738 | $443 | $295 |
| $60,000 | $1,938 | $969 | $581 | $388 |
| $75,000 | $2,369 | $1,185 | $711 | $474 |
| $100,000 | $3,045 | $1,523 | $914 | $609 |
Take-home is an estimate after 2026 federal income tax, Social Security and Medicare, with no state tax or other deductions. Your pay stub's net pay is the real number. See salary to biweekly paycheck for the full table and the math.
What about my 401(k) and health insurance?
Two ways work; pick one and stick to it.
- Simple: use net pay as it is. Your 401(k) is already out, so the 20% is on top of it. This is what most calculators assume.
- Closer to the book: add your 401(k) and health insurance back to net pay, run the split, then count the 401(k) inside the 20% and the insurance inside the 50%.
Check the result against what you spend now
The three numbers are targets. The useful part is comparing them with last month:
- Open last month's bank and card statements.
- Mark each charge N (need), W (want) or S (savings or extra debt payment). Minimum debt payments are N; anything above the minimum is S.
- Total each letter and divide by monthly take-home.
| What you find | What it means | First move |
|---|---|---|
| Needs under 50%, savings under 20% | Wants are taking the room | Move savings to payday, before you spend |
| Needs 50–60% | Common with rent or childcare | Run 60/20/20 for now |
| Needs over 60% | Rent, car or debt is too big for the income | Cut the biggest need first (below) |
| Total over 100% | The gap is going on cards or overdrafts | Stop the gap before splitting anything |

When needs are more than 50%
For many households paid paycheck to paycheck, rent alone takes 35–45% of take-home, so needs at 50% isn't possible this month. That doesn't mean the rule is useless; it means you start with a different split and work toward it.
| Your needs | Split to use | On $3,467 a month |
|---|---|---|
| Up to 50% | 50/30/20 | $1,733 / $1,040 / $693 |
| Around 60% | 60/20/20 | $2,080 / $693 / $693 |
| Around 70% | 70/20/10 | $2,427 / $693 / $347 |
| Around 80% | 80/10/10 | $2,773 / $347 / $347 |
Then lower needs where the big money is, one item at a time:
- Housing: a roommate, a cheaper unit at renewal, or a rent split across two checks.
- Car: refinance, a cheaper insurance quote, or selling a car with a large payment.
- Phone and internet: a prepaid plan and a cheaper internet tier often save $40–$80 a month.
- Debt minimums: ask card issuers for a lower rate, or look at a nonprofit credit counseling plan. See how to pay off credit card debt.
- Groceries: a list built from the week's meals, and store brands.
Our guide to 50/30/20 budget alternatives compares nine other splits on the same income, including zero-based and paycheck budgets.
What goes in each bucket
| Needs (50%) | Wants (30%) | Savings and debt (20%) |
|---|---|---|
| Rent or mortgage | Eating out, takeout, coffee | Emergency fund |
| Utilities, phone, internet | Streaming, apps, subscriptions | Extra debt payments above minimums |
| Groceries | Shopping, clothes beyond basics | Retirement (IRA, 401(k) if not already taken out) |
| Insurance: health, car, renters | Hobbies, gym, travel | Sinking funds for known yearly costs |
| Car payment, gas, transit | Gifts, holidays | Saving for a goal (a move, a car) |
| Minimum debt payments, childcare | Upgrades: a bigger plan, premium versions |
The grey areas (phone plan, internet speed, a gym you need for health) are covered line by line in our 50/30/20 budget examples, with three full budgets at real incomes.
Where the 20% goes first
- A starter emergency fund of $500 to $1,000. See how much your emergency fund should be.
- Any employer 401(k) match you'd otherwise miss.
- High-interest debt: credit cards, payday loans.
- The full emergency fund: 3 to 6 months of needs.
- Retirement and other goals.
Build it in a spreadsheet
If you'd rather keep it in Google Sheets or Excel, the calculator above is six cells:
| Cell | Label | Formula |
|---|---|---|
| B1 | Take-home per check | (type it: 1600) |
| B2 | Checks a year | (type it: 26) |
| B3 | Monthly take-home | =B1*B2/12 |
| B4 | Needs per check | =B1*0.5 |
| B5 | Wants per check | =B1*0.3 |
| B6 | Savings per check | =B1*0.2 |
To use your own split, put the percentages in C4:C6 (50%, 30%, 20%) and change the formulas to =$B$1*C4. Then add a column D with what you actually spent, and =D4/$B$1 in column E to see each bucket as a share of the check. Format column E as a percent.

Mistakes with a 50/30/20 calculator
- Entering gross salary. The split is for take-home. On gross pay, every bucket is too big.
- Treating 50/30/20 as monthly on biweekly pay without planning the third checks.
- Calling every want a need. If it's a need, ask whether a cheaper version would do the same job.
- Giving up when needs are 65%. Use a split that fits now, and move toward 50 as rent or debt comes down.
- Never checking. The targets only help if you compare them with real spending each month.
50/30/20 calculator questions
How do I calculate the 50/30/20 rule?
Take your monthly take-home pay and multiply by 0.5 for needs, 0.3 for wants and 0.2 for savings and extra debt payments. On $3,000: $1,500, $900 and $600.
Is 50/30/20 based on gross or net income?
Net: after taxes. The book it comes from uses after-tax income.
What is 50/30/20 on $2,000 a month?
$1,000 for needs, $600 for wants, $400 for savings and debt. On biweekly pay of about $923 a check, that's $462, $277 and $185 per check.
How do I do 50/30/20 biweekly?
Split each check: half to needs, 30% to wants, 20% to savings. Pay each bill from the check before it's due, and send most of the two extra checks a year to savings.
Do minimum debt payments count as needs?
Yes. Minimums are needs; anything you pay above the minimum counts in the 20%.
Is 50/30/20 realistic on a low income?
Often not at first, because rent takes more than half. Start with 70/20/10 or 80/10/10 and move toward it. Even 5% saved each check builds a cushion.
