Build a Habit of Checking Small Year-End Payment Leaks in Advance
990 won a month is more than 10,000 won a year
Small recurring payments are easy to miss on statements because each amount is low. Even just three or four charges of 990 won, 1,900 won, or 3,300 won a month can add up to 10,000 won monthly and 120,000 won a year. When you review everything at year-end, you will almost always find something that makes you wonder, “When did I start paying for this?”

Before year-end, review a full year of payment history
The key is to review 12 months at once, not just one month. Payments charged on the same day each month for the same amount are likely recurring payments. Mark unfamiliar names, charges listed only in English, and amounts you do not remember at all.
- Collect the most recent 12 months of records by payment method, such as cards, simple payment apps, and mobile carrier billing.
- Highlight items that repeat every month for the same amount.
- Next to each item, write O or X for whether you used it within the last 30 days.
- For items marked X, cancel or pause them immediately.
- For items you keep, write the next renewal date on your calendar.
Convert leaking money into annual amounts
Seeing the savings as a number is more motivating than vaguely saying, “I canceled a few things.” If you organize it in a table like the one below, you can see the money that has been leaking over the year at a glance.
| Item type | Monthly amount | Annualized | Recent use | Action |
|---|---|---|---|---|
| Small content payment | 1,900 won | 22,800 won | X | Cancel |
| Cloud storage | 1,100 won | 13,200 won | X | Switch to free plan |
| App add-on feature | 990 won | 11,880 won | △ | Pause |
| News/magazine | 3,300 won | 39,600 won | O | Keep |
| Total | 7,290 won | 87,480 won | - | Save 60,000 won a year |
Make the checkup a fixed annual event
Even after one cleanup, new payments will appear again, so the review itself needs to become a habit. Year-end is a good time because it is natural to look back while closing out the year, and it comes right before planning next year’s budget.
- Set the first weekend of every December as “small payment checkup day.”
- When starting a new subscription or payment, immediately write the date and amount in a notes app.
- For free trials, add the end date to your calendar as soon as you sign up.
Small payments leak longer because they feel small
Small payments are not large one-time expenses, so people notice the problem late. Even if 990 won, 1,900 won, or 3,300 won goes out every month, it gets buried in living expenses. At year-end, review 12 months of records instead of a single monthly statement and look for repeated payments.
Write canceled items as annual amounts, not monthly amounts. 3,300 won a month feels small, but it is 39,600 won a year. The larger number makes the value of cleaning things up visible.
