Quick Answer
A budget is your take-home pay minus your spending. The 50/30/20 rule suggests about 50% for needs, 30% for wants and 20% for savings and extra debt payments. On $5,000 a month, that is $2,500, $1,500 and $1,000.

How This Budget Calculator Works
Enter your monthly take-home pay, then what you spend in each group. The calculator shows what is left and how your spending splits between needs, wants and savings.
Quick explanation: left over = take-home pay − all spending and saving.
- Needs: housing, utilities, groceries, transport, insurance and minimum debt payments.
- Wants: dining out, fun, shopping and extras.
- Savings: saving, investing and extra debt payments.
How to Use the Budget Calculator
- Enter your monthly take-home pay, after tax and deductions.
- Enter what you spend each month in each group. Check bank statements for real numbers.
- Put savings and extra debt payments in the savings box.
- Press Calculate to see what is left over.
- Compare your needs, wants and savings with the 50/30/20 guide.
Core Formulas
- Total planned: needs + wants + savings
- Left over: take-home pay − total planned
- Share of pay: group total ÷ take-home pay × 100
- 50/30/20 guide: pay × 0.5, pay × 0.3 and pay × 0.2
Key Terms
- Take-home pay: what you receive after tax and other deductions.
- Needs: essential costs such as housing, food, transport and minimum debt payments.
- Wants: costs you could cut, such as dining out, hobbies and shopping.
- Sinking fund: money set aside each month for a known future cost, such as car insurance or holiday gifts.
- Emergency fund: savings kept for surprises such as job loss, medical bills or urgent repairs.
Worked Example
You take home $3,200 a month. Needs cost $1,900, wants $700 and you save $300.
- Total planned = 1,900 + 700 + 300 = $2,900
- Left over = 3,200 − 2,900 = $300
- Needs are 59.4% of pay, above the 50% guide
Real-Life Examples
- A tight month: take-home pay of $3,000 with $2,100 of needs leaves $900. Needs are 70% of pay, so wants and savings must fit in the rest.
- Finding money to save: cutting dining out from $400 to $250 and shopping from $300 to $200 frees $250 a month, or $3,000 a year.
- Paying off debt: putting $300 a month of savings toward a card at 20% APR can clear a $3,000 balance in under a year.
- Irregular income: if pay changes from month to month, budget with your lowest typical month and save any extra.
50/30/20 vs Zero-Based Budgeting
- 50/30/20: a simple split of take-home pay into needs, wants and savings. Easy to start with.
- Zero-based: every dollar gets a job until income minus spending and saving equals zero. More detailed and more effort.
- Envelope method: set cash or separate accounts for each category, and stop spending when one runs out.
- Pick one you will keep: the best budget is one you stick with month after month, not the most detailed one.

Budgeting Tips
- Use take-home pay: the amount after tax and deductions.
- Check yearly costs: divide them by 12, such as car repairs or gifts.
- Give every dollar a job: move any money left over to savings or debt.
- Build a buffer: an emergency fund stops surprises turning into debt.
Common Mistakes to Avoid
- Forgetting yearly costs. Divide insurance, car repairs, gifts and holidays by 12 and include them.
- Guessing spending. Check real statements from the last few months.
- Leaving no room for fun. Too strict a budget is hard to keep.
- Skipping an emergency fund. Without one, surprises go on a credit card.
- Not reviewing it. Update your budget when income or costs change.
Frequently Asked Questions
List your monthly take-home pay, then everything you spend and save. Subtract to see what is left.
A simple guide: about 50% of pay for needs, 30% for wants and 20% for savings and extra debt payments.
That is common where housing is expensive. Try to trim wants or raise income over time.
Use net (take-home) pay, as that is the money you can actually spend.
No. The numbers stay in your browser and are not stored.
The 50/30/20 rule suggests about 20% of take-home pay, but any regular amount is a good start.
A common guide is 3 to 6 months of essential costs. Our Emergency Fund Calculator can work out your target.
Minimum payments are needs. Anything you pay above the minimum counts toward the 20% for savings and debt payoff.
Start with wants, as they are easiest to cut. Then look at big needs such as housing, transport and insurance, and ways to raise income.
