Making a personal budget is the first step to taking control of your money. No matter how much you earn or spend: having a budget lets you know exactly where your money goes each month, plan your expenses in advance and reach your savings goals in a realistic way.
What is a personal budget?
A personal budget is a plan that distributes your income between your expenses and your savings. Its goal is for the money that comes in each month to be assigned consciously, so it does not slip away without you knowing where it went.
A good personal budget does not mean depriving yourself of anything. It means deciding wisely what you spend on and making sure there is always something left for savings.
Step 1: Calculate your monthly net income
The starting point of any budget is knowing how much money comes in each month. Write down all your net income: after-tax salary, extra income, freelance work, rental income or any other regular source of money.
If your income varies each month, calculate the average over the last 3 or 6 months and use that figure as a reference. Working with a stable figure is more reliable than planning based on your best month.
Step 2: Track all your expenses
The second step is knowing exactly what you spend on. For at least one month, note down all your expenses however small: coffee, transport, groceries, subscriptions, leisure... Everything counts and everything adds up.
Group expenses into categories for a clear picture of the money going out each month. Some common categories are:
- Housing: rent or mortgage, utilities, maintenance fees
- Food: groceries, restaurants, food delivery
- Transport: fuel, public transport, parking
- Leisure: outings, subscriptions, hobbies
- Health: insurance, pharmacy, gym
- Savings and investment
Step 3: Distinguish between fixed and variable expenses
Not all expenses are the same or offer the same room to act. Understanding the difference between fixed and variable expenses is key to knowing where you can adjust when you need to rebalance your budget:
- Fixed expenses: repeat every month with the same amount. Rent, mortgage, insurance, subscriptions. Hard to eliminate in the short term, but you can renegotiate or find cheaper alternatives.
- Variable expenses: change from one month to the next. Food, leisure, clothing, transport. This is where you have the most immediate capacity to adjust.
Step 4: Compare income and expenses
Once you have your income and expenses noted down, it is time to compare them. There are three possible scenarios:
- Income greater than expenses: you have room to save. Assign that surplus to a specific savings goal before it disappears into unplanned spending.
- Income equal to expenses: you are at the limit. Review variable expenses to find where to cut back without affecting your quality of life.
- Expenses greater than income: you are spending more than you earn. It is necessary to identify and eliminate unnecessary expenses urgently.
Step 5: Set your savings goals
A budget without savings goals is just a list of expenses. For your budget to truly work you need to assign part of your income to specific objectives: an emergency fund, a holiday, a car, home improvements or simply having a financial cushion for unexpected costs.
Key tip: treat savings like any other expense. As soon as you receive your salary, set aside the amount earmarked for savings before spending on anything else. If you wait to save «whatever is left over», there will usually be nothing left over.
Step 6: Review and adjust your budget every month
A budget is not something you do once and forget. Every month your expenses change, unexpected costs arise and your goals evolve. Spend a few minutes at the end of each month reviewing how your finances went and adjust next month's budget if necessary.
Over time this monthly review becomes a habit that gives you a clear picture of your real financial situation and lets you make more conscious decisions.
Which budgeting method should you use?
There are several popular methods for structuring a personal budget. The simplest and most effective are:
- 50/30/20 method: allocate 50% of your income to needs, 30% to wants and 20% to savings. It is the most recommended method to start with due to its simplicity. You can read more about how to apply it in our guide on what the 50/30/20 rule is.
- Zero-based budget: you assign every euro of your income to a category until the result is zero. More detailed but also more precise for those who want total control.
- Envelope method: you divide money into physical or digital envelopes by category. When the envelope runs out, you cannot spend more in that category during that month.
How often should I review my budget?
Monthly review is the minimum recommended. But there are key life moments when a deeper review makes sense: when you change jobs, move home, have a child or when your income changes significantly. A budget that is not updated stops being useful.
