Free tool: Budget CalculatorThe 50/30/20 rule is one of the simplest ways to budget: instead of tracking dozens of categories, you split your take-home pay into three buckets. Half goes to things you need, 30% to things you want, and 20% to savings and paying off debt. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth. This guide explains what belongs in each bucket, works through an example and shows how to adapt the rule, using the free Budget Calculator.
How the 50/30/20 rule works
Start with your monthly take-home pay, the amount that reaches your bank account after taxes and deductions. Then aim for:
- 50% for needs: the bills you must pay to live and work.
- 30% for wants: everything that makes life enjoyable but you could cut back on.
- 20% for savings and debt payoff: building your future, including paying debts down faster than the minimum.
On a take-home pay of $5,000 a month, that means $2,500 for needs, $1,500 for wants and $1,000 for savings, or $12,000 saved a year.
What goes in each bucket
| Needs (50%) | Wants (30%) | Savings and debt (20%) |
|---|---|---|
| Rent or mortgage | Dining out and takeout | Emergency fund |
| Utilities and phone | Entertainment and streaming | Retirement contributions |
| Groceries | Shopping and hobbies | Other investing |
| Transportation to work | Travel and vacations | Extra debt payments, beyond the minimums |
| Insurance and healthcare | Gym memberships | Saving for a home or other goals |
| Minimum debt payments | Upgrades, such as a newer phone |
The line between needs and wants isn't always obvious. A simple test: would you still have to pay it if you lost your job tomorrow? Groceries are a need; restaurant meals are a want. A basic phone plan is a need; the latest phone is a want. Minimum loan payments are needs, because missing them has consequences, while anything you pay above the minimum counts as savings.
A worked example
Here's a sample monthly budget on $5,000 of take-home pay (it's also the example the Budget Calculator opens with):
| Bucket | Target | Actual budget | Difference |
|---|---|---|---|
| Needs | $2,500 (50%) | $2,900 (58%) | $400 over |
| Wants | $1,500 (30%) | $900 (18%) | $600 under |
| Savings and debt | $1,000 (20%) | $900 (18%) | $100 under |
| Not yet assigned | $300 (6%) |
The needs bucket is $400 over target, mostly because rent takes $1,500, which is common where housing is expensive. Spending on wants is well under target, which makes up for it. The $300 that hasn't been given a job yet is the easiest win: moving it to savings would bring that bucket to $1,200, or 24% of income.
This is how the rule is meant to be used: as a quick check that shows where your money goes and what to adjust, not as a strict law.
When 50/30/20 doesn't fit
The percentages are guidelines. Common variations:
- 60/20/20 when housing and other essentials cost more, as in many big cities, while keeping savings at 20%.
- 70/20/10 when you're starting out or your income is tight; the important thing is to save something.
- More than 20% savings if you're aiming for early retirement or a house deposit. The FIRE Calculator shows what higher savings rates can do.
If your needs take well over half of your income, the long-term fixes are usually the big costs: housing, transportation and debt.
How to use the Budget Calculator
- Open the Budget Calculator.
- Enter your monthly take-home pay, after taxes and deductions.
- Choose your targets: pick the 50/30/20, 60/20/20 or 70/20/10 preset, or type your own percentages for needs, wants and savings.
- Fill in your monthly spending in each bucket, from rent and groceries to dining out, subscriptions, retirement and extra debt payments. Set any line you don't have to zero.
- Read the results: how much is left to assign (or how far over budget you are), how each bucket compares with its target, and a table of the target, your budget and the difference for each bucket. The chart shows the targets next to your actual spending.
Tips for making it stick
- Track a month of spending first. Your bank statements show where the money really goes, which is often different from where you think it goes.
- Save first, automatically. Set up a transfer to savings on payday, so the 20% happens before you can spend it.
- Build an emergency fund early. Three to six months of essential expenses is a common goal; the Emergency Fund Calculator works out your number.
- Attack expensive debt. High-interest credit card balances are worth paying off before most investing; see Debt Snowball vs. Debt Avalanche.
- Revisit after a raise. Put at least part of every raise toward savings before your spending rises to match it.
Frequently asked questions
Is the 50/30/20 rule based on gross or take-home pay?
On take-home pay, the money you actually receive after taxes. If you already save through your paycheck, for example in a 401(k), you can count those contributions toward your 20%.
What if my needs are more than 50% of my income?
That's common, especially with high rent. Use a split that fits, such as 60/20/20, and look for savings in the largest costs. Try to keep saving something every month, even if it's less than 20%.
Where do debt payments go in the 50/30/20 rule?
Minimum payments on any debt are needs. Anything extra you pay to clear debt faster goes in the 20% savings bucket.
