Budget calculator
Enter one normal month of after-tax income and spending. The calculator shows what is left, where pressure is building, and which next steps are worth checking first.
Use take-home pay after tax and payroll deductions.
Optional. Use this to compare your goal with the cash actually left.
How to use your result
If money is left over
Give it a job before it disappears: emergency buffer, upcoming bills, high-interest debt, or planned savings.
If the result is negative
Do not guess. Write down due dates, protect food, housing, utilities, and work transport first, then cut flexible costs.
If the target is too high
Lower the target temporarily or pick one spending category to reduce. A smaller repeatable amount beats a goal you cannot keep.
What to cut first when money is tight
Start with flexible spending
Cancel unused subscriptions, delivery fees, impulse buys, duplicate apps, and paid tools you rarely use.
Then review food and transport habits
Plan cheaper meals, reduce waste, pack lunch, combine errands, carpool, walk, cycle, or use public transport where practical.
Be careful cutting essentials
Do not cancel insurance, ignore rent, miss required payments, or skip medical needs without understanding the risk.
When cutting is not enough
Look for extra income, due-date changes, hardship options, local help, or qualified advice before using expensive short-term borrowing.
Common budget ranges are rough guideposts, not rules. A classic target is around 50% needs, 30% wants, and 20% savings or extra debt payoff.
Housing below 30% of take-home pay is easier to manage. Above that, the rest of the budget usually needs tighter limits.
Debt payments above 10% of take-home pay can slow progress. Above 20%, consider getting qualified local help before taking on more debt.
If your income is low or rent is high, these ranges may be impossible right now. Use them to spot pressure, not to judge yourself.
How this estimate is calculated
Monthly income and spending are added separately
The calculator treats monthly net income as the money available after tax and payroll deductions, then adds every spending category you enter.
Remaining cash is income minus expenses
Money left after expenses is the amount that may be available for savings, an emergency buffer, irregular bills, or extra debt payments.
Pressure ratios are based on income
Savings rate, rent percentage, debt percentage, needs percentage, and wants percentage are calculated against monthly net income.
Warnings compare your result with practical thresholds
The page flags negative cash flow, missed savings targets, high rent, high debt payments, and the largest spending category so you know what to review first.
Inputs
- $3,000 monthly net income
- $1,050 rent, $180 utilities, $420 groceries, and $180 transport
- $220 debt payments and $260 in subscriptions or other spending
- $200 monthly savings target
Result and next decision
- $2,310 total monthly expenses
- $690 left after expenses, or $490 after the savings target
- Rent is 35% of income and debt payments are about 7% of income
The budget is not negative, but rent is a pressure point. The next review should focus on flexible spending, transport, food habits, or a cheaper rent plan before adding new commitments.
Calculator FAQ
Should I use gross income or take-home income?
Use take-home income when possible. Gross income can make the budget look safer than it is because tax and payroll deductions are not available for spending.
How do I include annual or irregular bills?
Divide annual bills by 12 and enter the monthly amount. For example, a $600 yearly insurance bill becomes $50 per month.
What if the result is negative?
Protect food, housing, utilities, required transport, and minimum debt payments first. Then review flexible costs, provider hardship options, and realistic income changes.
Do I have to follow the 50/30/20 rule?
No. Budget ranges are guideposts. High rent, low income, debt, medical needs, family costs, or location can make common rules unrealistic for a while.
Can this calculator tell me what I should do?
It shows the math and pressure points, but it cannot know your local rules, contracts, taxes, family needs, health needs, or professional advice needs.
Budget calculator results are planning estimates based only on the numbers you enter. They are not financial, legal, tax, debt, or professional advice. Read how Earnio calculators work.
