Tools 50/30/20 Budget Calculator
How should you split your take-home pay?
The 50/30/20 rule gives half of your take-home pay to needs, 30% to wants and 20% to savings and extra debt payments. Enter your pay to see your targets in dollars, then add what you actually spend to see how close you are.

How this calculator works
Needs = pay × 50% · Wants = pay × 30% · Savings = pay × 20%
Everything starts from your monthly take-home pay, the money you can actually spend. On $4,000 a month, the rule sets aside $2,000 for needs, $1,200 for wants and $800 for savings and extra debt payments.
Needs are the bills you’d still have to pay if you lost your job tomorrow: housing, utilities, groceries, insurance, getting to work, childcare, and the minimum payment on every debt. Wants are everything you choose to spend on: eating out, entertainment, subscriptions, travel, and the upgrade portion of a need (a pricier phone plan or a bigger car than you need). Savings is money that raises your net worth: an emergency fund, retirement and other investing, and any debt payment above the minimum.
If you add what you spend now, each bucket is compared with its target. The verdict looks at your shares: spending past your pay is Over budget; saving 20% or more is Saving well; needs above 55% are Needs-heavy; wants above 35% are Wants-heavy; savings of 15% or more is Balanced; anything less is Room to save more. Treat 50/30/20 as a starting target. Where housing is expensive, needs often run higher, and the rule bends to fit your life rather than the other way round.
Words you’ll see
- Take-home pay
- Your pay after taxes: what reaches your bank account. The 50/30/20 rule uses this, not your gross salary.
- Needs
- Essential costs you must pay to live and work, including minimum payments on your debts.
- Wants
- Spending you choose and could cut without missing a bill, including the extra cost of upgrading a need.
- Savings and extra debt payments
- Money that builds your net worth: saving, investing, and paying debt down faster than the minimum.
- Unassigned money
- Take-home pay you haven’t given a job. It tends to drift into wants unless you send it somewhere on purpose.
Common questions
What is the 50/30/20 rule?
The 50/30/20 rule is a simple budget that splits your take-home pay three ways: 50% for needs, 30% for wants, and 20% for savings and extra debt payments. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth.
How do I calculate 50/30/20 on my salary?
Start with your monthly take-home pay, then multiply it by 0.5 for needs, 0.3 for wants and 0.2 for savings. On $4,000 a month, that is $2,000 for needs, $1,200 for wants and $800 for savings. If you're paid a yearly salary, use what actually reaches your account each month after taxes.
Is the 50/30/20 rule realistic?
For many households it's a useful starting target rather than a strict law. In high-cost areas or on a lower income, needs can take 60% or more, so some people start closer to 60/20/20 and move toward 50/30/20 as their income grows. What matters most is that savings get a fixed share before spending does.
Do debt payments count as needs or savings?
Minimum payments on loans and credit cards are needs, because you have to make them. Anything you pay above the minimum counts toward the 20% savings share, since paying debt off early raises your net worth just as saving does.
Is 50/30/20 based on gross or net income?
It's based on net income: your take-home pay after taxes. If retirement contributions or health insurance premiums come out of your paycheck first, add them back in, then count the retirement contributions as savings and the premiums as needs.
