Budget Planner
List every income source and every expense line, in any pay frequency. See monthly totals, your savings rate, your possible savings rate, how you compare with the 50/30/20 rule, and a flow chart of where each dollar goes.
Written by Suhaib Hassan. The 50/30/20 guide follows Warren and Tyagi. Our methodology.
Each line is turned into a monthly amount, then grouped into needs, wants and savings.
A single income box hides where money goes. Line items show it.

Where your money goes
Income flows into needs, wants and savings, then into each line.

Budget measures
Left over
income − (needs + wants + savings)Savings rate
savings lines ÷ incomePossible savings rate
(savings lines + left over) ÷ incomeChoosing the type for each line
Mark a line as a need if you must pay it to live and work, such as rent, groceries and minimum debt payments. Wants are what you could pause in a tight month. Saving covers emergency fund, retirement and extra debt payments.
For a quick split without line items, use the 50/30/20 Budget Calculator.
Worked example
The default budget: two income lines and thirteen expense lines. Yearly travel of $1,200 counts as $100 a month.
Totals
Income $4,200 + $300.
needs = 1,200 + 180 + 520 + 280 + 150 + 80 = $2,410
wants = 250 + 60 + 200 + 120 + 100 = $730
savings = 400 + 450 = $850
left over = 4,500 − 3,990 = $510
Savings rates
Savings and the money left over.
possible = (850 + 510) ÷ 4,500 = 30.2%
50/30/20 check
Shares of $4,500.
wants 730 ÷ 4,500 = 16.2% (guide 30%)
savings 850 ÷ 4,500 = 18.9% (guide 20%)
How to build a line-item budget
- List every source of income after tax, each with how often it arrives.
- List every expense, even small ones, and mark each as a need, a want or saving.
- Check what is left over. A negative number means spending is above income.
- Compare your shares with 50/30/20, then adjust the lines that are easiest to change.
Review the plan after a month against your bank statement and update the amounts that were off.

How pay frequency becomes a monthly amount
| Paid | Times a year | Monthly equivalent of $1,000 |
|---|---|---|
| Weekly | 52 | $4,333.33 |
| Every 2 weeks | 26 | $2,166.67 |
| Twice a month | 24 | $2,000.00 |
| Monthly | 12 | $1,000.00 |
| Quarterly | 4 | $333.33 |
| Yearly | 1 | $83.33 |
Savings rate vs possible savings rate
Your savings rate counts only the lines you marked as saving. Your possible savings rate adds the money left over, because that money could also be saved. In the example the two are 18.9% and 30.2%.
Frequently asked questions
What is the difference between a budget planner and a 50/30/20 budget calculator?
A 50/30/20 calculator splits one take-home figure into needs, wants and savings. A budget planner lists every income source and expense line so you see exactly where money goes, then compares the totals with the 50/30/20 guide.
How do I turn weekly or biweekly pay into a monthly budget amount?
Multiply weekly pay by 52 and divide by 12, or biweekly pay by 26 and divide by 12. A $1,000 weekly paycheck is $4,333.33 a month, and $1,000 every two weeks is $2,166.67. The planner does this for you when you pick the pay frequency.
What is a savings rate and how is it calculated?
Your savings rate is the money you save or invest divided by your income. Saving $850 from $4,500 a month is a savings rate of 18.9%.
What is the possible savings rate?
It adds the money left over after all planned spending to your planned savings, then divides by income. If you save $850 and have $510 unassigned from $4,500, the possible savings rate is (850 + 510) ÷ 4,500 = 30.2%.
Which expenses should I count as needs, wants or savings?
Needs are costs you must pay, such as rent, utilities, groceries, insurance and minimum debt payments. Wants are costs you could pause, such as dining out and subscriptions. Savings include your emergency fund, retirement contributions and extra debt payments.
What if my spending is higher than my income?
The planner shows a shortfall. Look at the wants first, since they are the easiest to cut, then review needs such as housing and transport. Even a small gap adds up over a year.
Should I enter income before or after tax?
Enter income after tax, the amount that reaches your bank account. Taxes taken out of your paycheck are not part of your spending budget.
How do I include irregular costs such as annual insurance or holidays?
Enter the full yearly cost and set the frequency to Yearly. The planner spreads it as one twelfth each month, so a $1,200 trip counts as $100 a month.
