5 Ways to Audit Monthly Expenses to Prevent Going Broke
Auditing doesn’t have to be as complex as a corporate financial report. You can start with practical steps that are relatable to your daily life. Here is a step-by-step guide to ensure your finances stay on track.
1. Collect Your Transaction History (E-wallets, Banks, & Cash)
The first step in how to audit monthly expenses is gathering all the data. Nowadays, our money is spread out: from main bank accounts to various e-wallet balances (GoPay, OVO, ShopeePay), and cash in our wallets. Don’t let anything slip through the cracks. You need to pull your transaction history for the entire past month.
Don’t forget to record cash transactions that are often hard to track, like parking fees, tips, or small grocery runs. Without complete data, your audit won’t be accurate. This is why using finance tracking apps is highly recommended so that all this history can be collected automatically or recorded quickly as transactions happen. By looking at all these numbers collectively, you’ll get the big picture of how much money is actually flowing out each month.

2. Break Down Categories: Needs vs. ‘Healing’ Wants
Once all the data is collected, it’s time to categorize. This is the most crucial part of how to audit monthly expenses. Separate your spending into several major categories like:
- Fixed Needs: Rent/mortgage, electricity, internet, work commute.
- Variable Needs: Daily meals, household essentials (soap, toothpaste, etc.).
- Wants/Lifestyle: Coffee, movies, clothes shopping, and weekend ‘healing’ costs.
- Obligations: Debt payments or insurance.
Many people get trapped by mixing up needs and wants. For example, a basic internet subscription for work is a need, but upgrading to the highest speed just for gaming might be a want. You can use the 50/30/20 method as a reference to see if your spending proportions are ideal. If your ‘wants’ portion exceeds 30%, it’s time for some serious cutting.

| Category | Spending Example | Audit Status | Action |
|---|---|---|---|
| Essentials | Rice, Electricity, Transport | Mandatory | Optimize (find more efficient options) |
| Entertainment | Streaming, Concerts | Optional | Limit or eliminate |
| Admin Fees | Bank Fees, E-wallet Top-ups | Often Forgotten | Find free/cheaper alternatives |
| Investment/Savings | Mutual Funds, Gold | Mandatory | Increase if there’s a surplus |
3. Check for ‘Ghost Expenses’ in Admin Fees & Subscriptions
Often, the reason a wallet goes broke isn’t big-ticket luxury items, but ‘ghost expenses’ that go unnoticed. When applying how to audit monthly expenses, you must be meticulous about checking bank admin fees, e-wallet top-up fees (which are usually 1,000 – 2,500 per transaction), and even parking fees that can add up to hundreds of thousands of rupiah when totaled.
Additionally, check your digital subscription list. Are you still watching all the streaming services you pay for? Is there a gym membership you never use? Automatic subscription fees (auto-debit) are the enemy in the shadows. If you haven’t used a service at least 3-4 times in a month, it’s better to cancel. The small change saved here can be allocated to strengthen your emergency fund.
4. Compare Initial Budget vs. Spending Reality
An audit is meaningless without a comparison. Look back at the budget plan you made at the start of the month (if any). Compare it with the reality you found during the audit. If you budgeted 1 million for food but actually spent 2 million, ask yourself: “Where did it go wrong? Was it because food prices went up, or because of too many food delivery app orders?”
This discrepancy is valuable insight. The essence of how to audit monthly expenses isn’t to punish yourself for past spending, but to provide accurate data so you can make smarter decisions in the future. If reality is always far above the budget, perhaps your budget is unrealistic, or your spending habits really need a total overhaul.
5. Evaluate and Set New Targets for Next Month
Once all the numbers are clear, the final step is evaluation. Determine at least three things you will change next month based on this audit. For example: “I will bring my own lunch 3 times a week,” or “I will limit e-wallet top-ups to a maximum of 2 times a week to avoid excessive admin fees.”
Every time you finish the how to audit monthly expenses process, you should feel more at ease because you know exactly where your finances stand. Don’t forget to set more specific savings goals. An audit is the bridge between your current financial condition and the financial freedom you dream of. Without evaluation, an audit is just recording numbers without any habit change.
Real Scenario: A 1-Hour Audit That Saved a Salary
Let’s look at a real example from Budi, a young employee in Jakarta with a salary of Rp 6,000,000 per month. Previously, Budi always felt his salary was gone by the third week. He decided to try how to audit monthly expenses by setting aside one hour on a Sunday afternoon.
Budi started opening his bank statements and e-wallet apps. He was shocked to find that in one month, he topped up his e-wallet 15 times. With an admin fee of Rp 2,500 per top-up, he had thrown away Rp 37,500 just on admin fees. Not to mention food delivery costs that totaled Rp 1,800,000, even though he felt he rarely ate fancy meals.
Budi’s Spending Comparison (Pre-Audit vs. Post-Audit):
| Spending Item | Pre-Audit (Estimate) | Post-Audit (Reality) | Next Month’s Plan |
|---|---|---|---|
| Dining Out/Delivery | Rp 1,000,000 | Rp 1,800,000 | Rp 1,000,000 (Cook at home) |
| Trendy Coffee | Rp 300,000 | Rp 650,000 | Rp 200,000 (Max 1x per week) |
| App Subscriptions | Rp 150,000 | Rp 400,000 | Rp 150,000 (Unsubscribe 2 apps) |
| Admin Fees | Rp 10,000 | Rp 85,000 | Rp 20,000 (Scheduled top-ups) |
| Total Savings | – | – | Rp 1,565,000 |
By practicing how to audit monthly expenses, Budi realized he could save more than Rp 1.5 million every month without sacrificing his basic needs. That money can now be allocated for gold savings and building a backup fund. Budi’s small step proves that an audit doesn’t take long, but the impact on your wallet’s health is massive.
Fatal Financial Audit Mistakes That Keep You Broke
Even though it looks easy, many people fail to get the maximum benefit from an audit because of a few fatal mistakes. Understanding these hurdles will help you execute how to audit monthly expenses more effectively.
Being Too Stingy with Yourself at the Start
The first mistake is going to the extreme. After seeing high spending, you decide to cut all entertainment costs and only eat rice and salt. This is a recipe for failure. Auditing isn’t about self-torture; it’s about balance. If you’re too stingy, you’ll feel stressed and eventually engage in “revenge spending” later on. Use the results of your how to audit monthly expenses to trim what’s unnecessary, not what keeps you sane.
Forgetting to Record Small Expenses
“Oh, it’s just two thousand for parking,” or “Just five thousand for a donation.” These small expenses often become big holes if they aren’t recorded. In how to audit monthly expenses, precision is key. Unrecorded small spending can reach 10-15% of your total expenses. If you feel like your balance doesn’t match your records, there’s a good chance many small expenses were missed.
Auditing Without Changing Habits
This is the most common mistake. You already know where your money goes, you know where you’re overspending, but you don’t change your spending behavior the following month. An audit is just a diagnosis; habit change is the cure. Without real action after practicing how to audit monthly expenses, you’ll just keep seeing the same numbers that stress you out every month.
Tools for Easier Auditing: Manual vs. Automatic
Many people are reluctant to audit because they imagine collecting piles of paper receipts in their wallets or typing them one by one into Excel. Manual methods do have the advantage of making you more aware of every number, but for busy young people, this method is often abandoned halfway because it’s considered too much of a hassle.
This is where finance tracking apps like MoneyKu come in as a modern solution. MoneyKu is designed to remove that “hassle” barrier. With fast recording features and pre-set categories, you no longer have to worry about building your own tables.

FAQ: Common Questions Before Starting an Audit
What is the ideal amount of time for an audit?
For beginners, you might need about 45-60 minutes for your first deep monthly audit. However, if you’re used to using an app to record every transaction, the how to audit monthly expenses process will only take 10-15 minutes at the end of each month since all the data is already available and neatly organized.
How do I audit if I rarely use cash?
This is actually easier! If most of your transactions are via e-wallets or debit, you just need to download your transaction history or bank statements from your mobile banking app. You no longer need to remember what the money was for, because it’s all digitally recorded. You just need to input those numbers into your audit system or favorite finance tracking app.
Does auditing have to be done every day?
No. Recording transactions should be done daily (real-time) so you don’t forget, but the audit process (major review and evaluation) only needs to be done once a month. However, some feel more comfortable doing a mini-audit every week (weekly review) so they can immediately slow down spending if they’ve been too extravagant in the first week. The more often you monitor, the less likely you are to go broke.
What if I find unavoidable expenses that cause a budget deficit?
This is exactly what the audit is for. If you’ve trimmed your wants but still have a deficit due to high essential costs, it means you need a new strategy. You might need to find additional income sources or look for cheaper alternatives for essentials. Also, make sure you always set aside a little money for an emergency fund so that when unexpected expenses arise, you don’t have to disrupt your monthly budget.
Starting today, don’t let your money flow aimlessly. Apply how to audit monthly expenses consistently and feel the difference. With clear data, you can not only prevent going broke but also start building a brighter financial future with MoneyKu. Remember, managing money isn’t about how much you earn, but how smartly you keep it.
