Build a simple budget with the 50/30/20 rule
Not sure how much you should spend on rent, fun, or savings? The 50/30/20 rule is an easy place to start. It splits your take-home pay into three groups: 50% for needs, 30% for wants, and 20% for savings and debt payments. This free 50/30/20 budget calculator shows those targets in dollars based on your income, and if you add what you actually spend, it shows how close you are.
How to use the 50/30/20 calculator
This monthly budget calculator works from your take-home pay.
- Enter your Monthly take-home pay (what lands in your bank account after taxes and deductions).
- Read your targets in dollars for Needs, Wants, and Savings and debt payments. The calculator starts at 50/30/20.
- Want a different split? Change Needs %, Wants %, and Savings and debt payments %. The three must add up to 100. Click Reset to 50/30/20 to go back.
- Optional: under Actual spending (optional), enter what you actually spend each month on Needs, Wants, and Savings and debt payments.
- Compare your actual amounts and percentages to the targets. The calculator shows how far over or under target each group is, plus any money left unassigned.
Example: 50/30/20 budget on $5,000 a month
These are example numbers to show how the math works.
Your 50/30/20 targets:
- Needs (50%): $2,500. See how much rent you can afford.
- Wants (30%): $1,500
- Savings and debt payments (20%): $1,000
Now add actual spending. Say you spend $2,800 on needs, $1,200 on wants, and $700 on savings and debt payments:
- Needs: $2,800, or 56%. That is $300 over target.
- Wants: $1,200, or 24%. That is $300 under target.
- Savings and debt payments: $700, or 14%. That is $300 under target.
- Unassigned: $300 you haven't planned for yet.
In this example, moving the $300 that is left unassigned into savings would bring that group right to its $1,000 target.
Tips for using the 50/30/20 rule
- Start with your real numbers. Look at last month's spending before you pick targets.
- Plan for leftover money. Money without a plan tends to disappear.
- Trim wants before needs. Wants are usually the easiest place to find room.
- Treat the split as a guide. If you live somewhere with high rent, a 60/20/20 split can still work. Change the percentages above to try it.
- Count extra debt payments as savings. Paying down a credit card or loan faster helps your future self just like saving does.
Other budget rules to try
60/20/20: Put 60% toward needs, 20% toward wants, and 20% toward savings and debt payments. It works well when rent or other fixed costs take up more of your pay. To try it, set the calculator to 60, 20, and 20. On $5,000 a month, that's $3,000 for needs, $1,000 for wants, and $1,000 for savings and debt payments.
70/20/10: Put 70% toward living expenses (needs and wants together), 20% toward savings, and 10% toward extra debt payments or giving. It is simpler to follow, but it doesn't show how much goes to wants.
50/30/20 budget calculator FAQ
What is the 50/30/20 rule?
It is a simple budgeting guideline. You put 50% of your take-home pay toward needs, 30% toward wants, and 20% toward savings and paying down debt.
Is the 50/30/20 rule before or after taxes?
After taxes. Use your take-home pay, the amount that actually reaches your bank account after taxes and deductions.
What counts as a need and what counts as a want?
Needs are things you have to pay to live and work, like rent or mortgage, utilities, groceries, insurance, transportation, and minimum debt payments. Wants are things you choose, like dining out, streaming, shopping, hobbies, and travel. A basic phone plan is a need. The newest phone is a want.
Do debt payments go in the 20%?
Minimum payments usually count as needs, because you have to make them. Anything you pay above the minimum goes in the 20% for savings and debt payments.
How do I use the 50/30/20 rule if I get paid weekly or biweekly?
If you get paid biweekly, multiply one paycheck by 26, then divide by 12 to get your monthly take-home pay. If you get paid weekly, multiply one paycheck by 52, then divide by 12. Enter that number above. For example, $2,000 every two weeks is about $4,333 a month.
Where do retirement contributions go in the 50/30/20 rule?
They count toward the 20% for savings and debt payments. If retirement money comes out of your paycheck before you get paid, add that amount to your take-home pay and to your 20% so the math stays accurate.
What if my needs are more than 50%?
That is common, especially with high rent. Start by trimming wants to make up the difference, and look for needs you can lower over time, like insurance or phone bills. The goal is progress, not a perfect split on day one.
Is the 50/30/20 rule realistic on a low income?
It can be harder, because needs like rent and groceries take a bigger share of a smaller paycheck. Use the split as a starting point, not a test. Even saving 5% or 10% builds the habit, and you can move toward 20% as your income grows or your costs come down.
What is the difference between the 50/30/20 and 70/20/10 rules?
The 70/20/10 rule groups needs and wants together as 70% for living expenses, then puts 20% toward savings and 10% toward extra debt payments or giving. The 50/30/20 rule keeps needs and wants separate, which makes it easier to see where you can cut back.
Can I change the 50/30/20 percentages?
Yes. Enter your own split in the Needs %, Wants %, and Savings and debt payments % fields, as long as they add up to 100. Your targets update right away. Click Reset to 50/30/20 to start over.
