How to use this calculator
- Income. Choose Take-home pay and enter what reaches your bank account each month, or choose Estimate it and enter your salary, state, filing status and 401(k) percentage.
- Retirement savings taken from your pay (take-home mode). If your employer deducts 401(k) or 403(b) contributions, enter the monthly amount. It counts toward savings and toward the income the 50/30/20 percentages are based on.
- Needs, wants and savings. Fill in each category as a monthly amount. Leave anything you don’t spend at $0. Convert yearly bills to monthly by dividing by 12.
The results show what’s left over (or how far over budget you are), your split between needs, wants and savings, how each compares with its 50/30/20 target, and a table of every category with its share of your income.
The 50/30/20 rule
The 50/30/20 rule was popularized by Elizabeth Warren and Amelia Warren Tyagi in All Your Worth (2005), and the Consumer Financial Protection Bureau uses it in its financial education lessons. It splits after-tax income three ways:
- Needs (50%): rent or mortgage, utilities, groceries, transportation, insurance, childcare and minimum payments on debts.
- Wants (30%): dining out, entertainment, subscriptions, shopping, travel and hobbies.
- Savings (20%): emergency fund, retirement and investing, and debt payments above the minimum.
After-tax income here means take-home pay plus any savings deducted from your paycheck. Health insurance premiums deducted from pay are a need you’ve already paid; if you want them counted, add them back to income and enter them under insurance.
Whatever isn’t assigned shows up as left over. Giving every dollar a job, often by sending the leftover to savings or debt, is what turns a budget into a plan.
Worked example
You take home $5,000 a month. Your plan:
| Bucket | Your plan | Share | 50/30/20 target | Difference |
|---|---|---|---|---|
| Needs | $2,850 | 57% | $2,500 | $350 over |
| Wants | $800 | 16% | $1,500 | $700 under |
| Savings & debt payoff | $500 | 10% | $1,000 | $500 under |
| Left over | $850 | 17% |
Needs run a bit high, mostly because rent is $1,500 (30% of take-home). But wants are well under target, which leaves $850 unassigned. Moving $500 of it into savings hits the 20% target; saving all of it raises your savings rate to 27%.
50/30/20 at different take-home pay levels
| Monthly take-home | Needs (50%) | Wants (30%) | Savings (20%) | Savings per year |
|---|---|---|---|---|
| $3,000 | $1,500 | $900 | $600 | $7,200 |
| $4,000 | $2,000 | $1,200 | $800 | $9,600 |
| $5,000 | $2,500 | $1,500 | $1,000 | $12,000 |
| $6,000 | $3,000 | $1,800 | $1,200 | $14,400 |
| $8,000 | $4,000 | $2,400 | $1,600 | $19,200 |
| $10,000 | $5,000 | $3,000 | $2,000 | $24,000 |
The savings calculator shows what those yearly amounts could grow to.
Estimating take-home pay from a salary
Choose Estimate it and the calculator runs the same 2026 engine as the paycheck calculator: federal withholding from IRS Publication 15-T, Social Security and Medicare, and state income tax. Estimated monthly take-home for a single filer with no 401(k) contributions:
| State | $50,000 salary | $75,000 salary | $100,000 salary |
|---|---|---|---|
| Texas or Florida | $3,530 | $5,133 | $6,598 |
| Pennsylvania | $3,399 | $4,936 | $6,337 |
| California | $3,394 | $4,829 | $6,081 |
| Illinois | $3,335 | $4,835 | $6,198 |
| New York | $3,334 | $4,815 | $6,156 |
Local income taxes, such as New York City’s or Pennsylvania’s local earned income taxes, are not included. With the default 5% 401(k) contribution, a $75,000 salary in Illinois takes home about $4,607 a month and saves $313 through payroll, so the 50/30/20 percentages are figured on about $4,920.
When your numbers don’t fit
- Needs over 50%. Look at housing first. The rent affordability calculator shows what rent fits your income, and transportation is often second. Small cuts across many needs rarely move the total as much as one big one.
- Wants over 30%. Check subscriptions and dining out, which tend to creep. Set a monthly amount for each and track against it for a couple of months.
- Savings under 20%. Automate a transfer on payday so saving happens before spending. Build an emergency fund first, then increase retirement contributions.
- Carrying high-interest debt. Payments above the minimum count toward the 20%. The debt payoff calculator shows how fast extra payments clear balances, and the debt-to-income ratio calculator shows how lenders see your debt load.
Track your net worth once or twice a year to see the budget working over time.
Assumptions & limitations
All amounts are monthly. The take-home estimate assumes a single earner paid monthly with no dependents, no pre-tax health premiums and no local income tax, using 2026 tax rules; your pay stub may differ. The 50/30/20 split is a guideline popularized for household budgeting, not an official standard, and your own priorities may call for a different split.

Frequently asked questions
What is the 50/30/20 rule?
It's a simple way to divide after-tax income into three buckets, with 50% for needs, 30% for wants and 20% for savings and extra debt payments. Elizabeth Warren and Amelia Warren Tyagi popularized it in their 2005 book All Your Worth. It's a starting point for a budget, not a strict rule.
Is the 50/30/20 rule based on gross or net income?
It's based on after-tax income. Start with your take-home pay and add back anything your employer deducts for savings, such as 401(k) contributions, since those count toward the 20%. The calculator does this when you enter retirement savings taken from your pay or estimate pay from a salary.
How much of a $5,000 monthly take-home should go to each category?
Under the 50/30/20 rule, $2,500 goes to needs, $1,500 to wants and $1,000 to savings and extra debt payments. If your rent and other essentials already take more than $2,500, the usual advice is to protect the savings share and spend less on wants.
What counts as a need versus a want?
Needs are costs you must pay to live and work, such as housing, utilities, groceries, transportation, insurance and minimum debt payments. Wants are things you choose, such as dining out, streaming services, travel and most shopping. A basic phone plan is a need; the newest phone is a want.
What if my needs are more than 50% of my income?
That's common, especially for renters in expensive cities and people early in their careers. Housing is usually the biggest lever, through a roommate, a cheaper unit or refinancing. In the meantime, keep saving something every month, even if it's less than 20%, and let wants absorb the difference.
How accurate is the take-home pay estimate?
It uses 2026 federal withholding tables, Social Security and Medicare, and state income tax for a single earner with no dependents, paid monthly. It doesn't include local income taxes, health insurance premiums or other paycheck deductions. For the most accurate budget, enter the amount that actually reaches your bank account.
