How to use the budget calculator
- Enter your monthly take-home pay: what reaches your bank account after taxes and deductions.
- Pick a split, such as 50/30/20, 60/30/10 or 70/20/10, or set your own percentages with the sliders.
- Enter what you actually spend on needs, wants and savings and debt to see where you’re over or under plan.
The 50/30/20 rule
The rule splits take-home pay into three buckets:
- 50% for needs: housing, utilities, groceries, insurance, transportation and minimum debt payments.
- 30% for wants: eating out, entertainment, travel, subscriptions and shopping beyond the basics.
- 20% for savings and debt: an emergency fund, retirement, other goals and extra payments on debt.
Our 50/30/20 rule guide explains how to sort your expenses into each bucket.
Example: $4,800 a month take-home pay
| Bucket | Plan (50/30/20) | Actual | Difference |
|---|---|---|---|
| Needs | $2,400 | $2,650 | $250 over |
| Wants | $1,440 | $1,350 | $90 under |
| Savings & debt | $960 | $600 | $360 under |
Here, needs run $250 over plan, savings $360 under, and $200 a month isn’t assigned to anything. Moving that $200 to savings and trimming wants would close most of the gap. If high rent makes 50% for needs unrealistic, a 60/30/10 split ($2,880 / $1,440 / $480) can be a starting point while you work toward saving more.
How to find your take-home pay
Use your net pay: what lands in your account after income tax, Social Security and Medicare, and deductions such as health insurance. If you contribute to a 401(k) through payroll, you’re already saving; some people add those contributions back to their income and count them in the savings bucket. Our guide to reading a pay stub shows where to find each number. If your income varies, budget with a cautious figure, such as your lowest recent month.
Tips for sticking to a budget
- Pay yourself first: set up an automatic transfer to savings on payday.
- Track your spending for a month to see where the money really goes.
- Cut the big costs first. Housing, transportation and food usually matter most.
- Build an emergency fund; our savings calculator works out the monthly amount.
- Clear high-interest debt with a plan from our credit card payoff calculator.
Frequently asked questions
What is the 50/30/20 budget rule?
A simple guideline: spend about 50% of take-home pay on needs and 30% on wants, and put 20% toward savings and paying down debt.
How much should I spend on rent?
Under the 50/30/20 rule, rent is part of the 50% for needs. A common guideline is to keep rent to about 30% of gross income, but in high-cost areas many people need a different split.
Is the 50/30/20 rule realistic?
Not for everyone. If needs take more than half your pay, start with 60/30/10 or 70/20/10 and adjust as your income or costs change. What matters most is saving something every month.
Do debt payments count as needs or savings?
Minimum payments are usually counted as needs. Anything extra you pay toward debt counts in the 20% for savings and debt.
Should I budget with gross or net income?
The 50/30/20 rule uses take-home (net) pay: the money you actually have to spend each month.
