In short
- Use take-home pay, not your salary before taxes.
- Fixed bills and savings first, flexible spending after.
- For shared costs, only your share counts, and money paid back to you is not income.
- Check it every month against what you really spent.
Five steps to make a monthly budget
- Your monthly income: what actually hits your account after taxes and deductions. If your pay varies, plan around a slow month.
- Fixed bills: rent, utilities, phone, car or transit, loan payments. Check your statements so nothing slips.
- Savings, off the top: move it as soon as you get paid, not from whatever is left over.
- Flexible spending: groceries, eating out, delivery. Give each one a limit, and see what small repeat purchases add up to with the small spending calculator.
- A buffer: a small amount for what you did not plan.
The 50/30/20 rule (50% for needs, 30% for wants and 20% for savings and debt) works as a starting point, not a law.
An example with $3,400
Emma takes home $3,400 a month and shares an apartment with a roommate.
| Category | Amount |
|---|---|
| Fixed: her share of rent, utilities, phone and transit | $1,695 |
| Savings | $600 |
| Groceries | $420 |
| Eating out | $200 |
| Coffee and delivery | $85 |
| Other | $100 |
| Buffer | $300 |
| Total | $3,400 |
The fixed bills are $1,400 for rent, $90 for utilities, $45 for her phone and $160 for transit. Every dollar has a job.
How to budget for shared expenses
If Emma pays a $96 dinner for four and her friends pay her back $72, her expense for the month is $24, her share. The $72 she gets back is not income: it just settles what they owed. Count it as income and the month looks better than it is.

Frequently asked questions
How much should I save each month?
What you can keep up every month. Starting small and staying consistent beats a big number you drop after a month.
How do I budget with irregular income?
Build the budget around a slow month. When you earn more, send the extra to savings or to a buffer for the lean months.
