Why a budget is worth it
Without a budget, money gets spent first and counted later. With a budget, the order flips: you decide in advance how much goes to each thing and, at the end of the month, you check whether you stuck to it. It has three clear benefits:
- You know how much you can spend without putting your bills at risk.
- You spot the small expenses that, added up, eat into your savings.
- You can plan specific goals, such as a holiday or a deposit for a home.
Step 1: work out your net income
Start with the money that actually lands in your account each month: take-home pay, self-employed income after tax, rental income, pensions or benefits. If your income varies, use the average of the last six months or, better still, your lowest month. It’s better to underestimate and have money left over than the other way round.
Step 2: list your expenses
Go through your bank and card transactions for the last three months and sort every expense. A simple set of categories works better than a very detailed one:
- Housing: rent or mortgage, service charges and home insurance.
- Utilities: electricity, water, gas, internet and phone.
- Groceries: supermarket and market shopping.
- Transport: fuel, public transport and car maintenance.
- Leisure and eating out: dinners, outings and subscriptions.
- Other: clothes, health, gifts and education.
Don’t forget annual or quarterly costs, such as insurance, taxes or the car service. Divide them by twelve and set aside that amount every month.
Step 3: split your money with the 50/30/20 rule
If you don’t know where to start, the 50/30/20 rule is a good starting point:
- 50% for needs: housing, food, utilities, transport and minimum debt repayments.
- 30% for wants: leisure, eating out, travel and treats.
- 20% for savings and debt: emergency fund, goals and extra repayments.
It isn’t a law: if you live in an expensive city, your needs may reach 60%. What matters is that savings get a fixed amount instead of being “whatever is left”, because usually nothing is left.
Step 4: set a limit for each category
Turn the percentages into real amounts. For example, with €2,000 net a month: €1,000 for needs, €600 for wants and €400 for savings. Within each block, give every category a limit (€300 for groceries, €150 for eating out…). The more specific the limits, the easier they are to stick to.
Step 5: review it every month
A budget only works if you compare it with reality. Spend ten minutes at the end of the month checking how much you spent in each category and adjust any limits that aren’t realistic. It’s normal to go off track in the first few months: that isn’t failure, it’s information to fine-tune the plan.
Common mistakes
- Making the budget too strict, with no room for surprises or fun.
- Forgetting annual costs and getting hit by them all at once.
- Not recording small cash or phone payments.
- Giving up the first month it doesn’t go to plan.
How Calers helps
In Calers you create a budget for each category, over any period you like (monthly, quarterly, yearly…), and always see how much you’ve spent and how much is left. Colours warn you when you’re close to the limit or over it. You can also create savings goals with an amount and a date, and link them to an account so your progress updates automatically.
