50/30/20 Budget Calculator
Split your take-home pay into needs, wants and savings — or set your own percentages

1. Enter Your Take-Home Pay
Gross vs. take-home pay: which number do I use?
Gross pay is your salary before anything is withheld. Take-home (net) pay is what is left after income taxes, Social Security and Medicare, and payroll deductions such as health insurance. The 50/30/20 rule uses take-home pay, because that is the money you can actually budget.
For example, if your pay stub shows $4,000 gross but $3,100 is deposited, enter $3,100. If you have retirement contributions taken out of your paycheck, you can add them back to your take-home figure and count them as part of your savings share.

How to Use This 50/30/20 Calculator
- Enter your take-home pay. Use your monthly after-tax income, or your annual after-tax income and the calculator divides it by 12.
- Pick a split. Keep the standard 50/30/20, choose a preset such as 60/20/20 or 70/20/10, or type your own percentages. The three numbers must add up to exactly 100%.
- Click Calculate Budget. You get monthly, weekly and daily amounts for needs, wants and savings. Change the percentages afterwards and the results update automatically.
- Compare with what you actually spend. Add up last month's essentials, extras and savings and see which category is over or under its target.

Frequently Asked Questions
The 50/30/20 rule is a simple budgeting method that divides your after-tax income into three categories: 50% for needs (essentials like housing and food), 30% for wants (entertainment and extras), and 20% for savings and debt repayment. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book "All Your Worth."
After-tax (take-home) income. Gross pay includes money you never receive, such as income tax and payroll taxes, so splitting it would overstate what you can spend. Use the amount deposited into your account. If retirement contributions or other savings come out of your paycheck, you can add them back and count them toward the savings share.
Yes. Choose a preset from the split menu or select "Custom percentages" and type your own numbers. A 60/20/20 split is common where rent is high, and 70/20/10 can work as a temporary plan when essentials take up most of your income. The rule is a starting point, not a strict law.
A budget split has to total exactly 100% of your take-home pay, otherwise you are planning to spend money you don't have. A 50/30/32 split adds up to 112%, so you would need to take 12 points away from one or more categories, for example 50/18/32 or 46/22/32. The calculator shows a warning and won't calculate until the total is 100%.
Minimum required payments on loans and credit cards count as needs, because you have to make them. Any extra payment above the minimum counts toward the 20% savings and debt category. If your loan payments push needs well over 50%, a 60/20/20 or 70/20/10 split may be more realistic while you pay them down.
Needs are expenses you can't skip without hurting your basic quality of life: rent or mortgage, utilities, groceries, insurance, minimum debt payments, transportation to work and basic clothing. Wants are everything optional: dining out, entertainment, hobbies, streaming services, travel and upgrades beyond the basics.
20% is a solid starting point, but you may need to adjust based on your goals. If you're behind on retirement savings or have high-interest debt, consider increasing this percentage. If you live in a high-cost area, you might need to shift some of the wants share to needs instead.
How to Use the 50/30/20 Rule Effectively
Step 1: Calculate Your After-Tax Income
Start with your take-home pay: what's left after taxes, health insurance and other payroll deductions.
Step 2: Track Your Current Spending
Before implementing the rule, track your spending for a month to see where your money currently goes.
Step 3: Categorize Your Expenses
Sort all your expenses into needs, wants, or savings/debt categories. Be honest about what's truly necessary.
Step 4: Make Adjustments
If your spending doesn't match your target split, identify areas where you can cut back or reallocate funds. Changing the percentages is fine too, as long as they add up to 100%.
Step 5: Automate Your Budget
Set up automatic transfers to savings and automatic bill payments to stick to your budget. A savings goal tracker or an emergency fund calculator can help you decide where your savings share should go first.
