Start with money available this month
Use your expected take-home income after deductions. Then write down bills you need to cover, a realistic amount for flexible spending, and what you plan to set aside. If income varies, use a cautious estimate and adjust when the actual amount arrives.
A monthly budget is a plan for where income may go. It is not a record of what you have already spent, and it does not guarantee your account balance on any day.
A worked monthly example
Suppose your monthly take-home income is €3,000.00. This is a hypothetical plan, not a customer result or a recommended allocation for everyone. List essential costs first, then flexible choices and savings.
| Group | Category | Planned |
|---|---|---|
| Essential | Housing | €1,100.00 |
| Essential | Utilities | €180.00 |
| Essential | Groceries | €400.00 |
| Essential | Transport | €220.00 |
| Flexible | Leisure | €350.00 |
| Flexible | Dining out | €150.00 |
| Savings | Emergency savings | €400.00 |
| Total planned | €2,800.00 | |
| Unallocated buffer | €200.00 | |
The essential bills add up to €1,900, flexible spending to €500, and planned savings to €400. That is €2,800.00 allocated. Subtract it from €3,000.00 to leave a €200.00 buffer for costs you may have missed or choose to reserve. Do not count the same savings transfer again as an expense.
Revise the plan when it runs short
Imagine your grocery estimate rises from €400 to €650 while everything else stays the same. Planned expenses and savings become €3,050.00, which is €50.00 more than the income. The original €200 buffer absorbs most of the increase, but the plan still has a €50 shortfall.
In this illustration, reducing dining out from €150 to €100 brings the revised total to €3,000.00 and the remainder to €0.00. That balances the arithmetic, but leaves no buffer. If the higher grocery cost is likely to continue, review other flexible choices or the savings target to make room for uncertainty. Keep essential bills realistic rather than lowering a number just to make the table balance.
Make the plan your own
To reproduce the example, enter €3,000 as income and add the seven category amounts in the table. The free Monthly Budget Calculator lets you add expense and savings rows and shows the remainder as you edit. Then substitute your own amounts. Its result is a snapshot of the amounts you entered, so compare it with actual transactions during the month and update the plan when costs change.
There is no single percentage split that fits every household. Rent, debt payments, irregular income, family needs, and savings priorities all affect what is workable. For ongoing planning inside Spendly Budget, explore the monthly budget feature and check its plan availability. Calculator inputs are not transferred into an account.
Once the monthly amounts balance, check when the money actually moves. Our €3,000 salary timing example shows how bills can cause a shortfall before payday even when the month's totals look healthy.
