A monthly budget needs to account for more than everyday spending. Payments that recur but are not due every month, such as tuition each term, annual insurance or quarterly fees, can create a shortfall in the month they fall due.
This article explains how to identify recurring obligations, calculate their monthly equivalents and plan spending around them. It describes a manual method, not how to use an application.
Step 1: Find recurring payments in your statements
Use statements rather than relying solely on memory. Moneysmart recommends checking bank statements to ensure all expenses have been recorded, including each payment’s purpose, amount and timing. Its spending-tracking guidance suggests reviewing transactions from the last few months, identifying bills that arrive quarterly or annually and checking for unused subscriptions.
Review a full 12 months of records to identify payments made only once a year. The 12-month review is a suggestion from this article, not from Moneysmart. Look for:
- Monthly payments: rent, internet, phone and software subscriptions.
- Quarterly payments: some service fees.
- Payments each school term or every six months: tuition.
- Annual payments: insurance, membership fees, domain renewals or document renewals.
Step 2: Create a table of recurring obligations
Record each payment in a separate row using consistent columns. All amounts in this article are in Vietnamese dong (VND); commas separate thousands.
| Payment | Frequency | Amount per payment | Due month or day |
|---|---|---|---|
| Rent | Monthly | VND 6,000,000 | 5th |
| Internet | Monthly | VND 300,000 | 10th |
| Software subscription | Monthly | VND 120,000 | 15th |
| Tuition | Twice a year | VND 6,000,000 | September and February |
| Family health insurance | Annually | VND 4,800,000 | September |
| Parking fee | Quarterly | VND 450,000 | Start of the quarter |
The figures in the table are educational examples only. They do not represent actual prices, personal data or results produced by an application. If you use multiple accounts, add a payment account column to identify where funds must be available before the due date.
The CFPB in the United States includes a bill calendar and a cash flow budget tool in its toolkit. This article interprets their general purpose as consolidating due dates in one place for review.
Step 3: Calculate monthly equivalents
Convert each payment to its monthly equivalent so that amounts with different frequencies can be compared:
| Frequency | Calculation of monthly equivalent |
|---|---|
| Monthly | Keep the amount unchanged |
| Quarterly | Divide by 3 |
| Twice a year | Multiply by 2, then divide by 12 |
| Annually | Divide by 12 |
| Weekly | Multiply by 52, then divide by 12 |
| Every two weeks | Multiply by 26, then divide by 12 |
Moneysmart notes that its budget tool accepts amounts at different frequencies, such as weekly, fortnightly, monthly, quarterly or annually, and warns that an incorrect frequency will distort the result. The conversions above are this article’s calculations, not quotations from the tool.
Using the example in step 2:
| Payment | Monthly equivalent |
|---|---|
| Rent | VND 6,000,000 |
| Internet | VND 300,000 |
| Software subscription | VND 120,000 |
| Tuition | VND 1,000,000 |
| Family health insurance | VND 400,000 |
| Parking fee | VND 150,000 |
| Total | VND 7,970,000 |
The total is: 6,000,000 + 300,000 + 120,000 + 1,000,000 + 400,000 + 150,000 = VND 7,970,000.
Step 4: Account for cash shortfalls in months when payments are due
For illustration, assume monthly net income of VND 15,000,000. Recurring obligations have a monthly equivalent of VND 7,970,000, leaving VND 7,030,000 for everyday spending, savings and a contingency reserve.
If tuition and insurance are both due in September, however, the actual amount payable that month is:
6,000,000 (rent) + 300,000 (internet) + 120,000 (software) + 6,000,000 (tuition) + 4,800,000 (insurance) = VND 17,220,000
This exceeds the VND 15,000,000 monthly income by VND 2,220,000, before food or transport costs. A budget that does not account for payment timing can therefore show an unexpected monthly shortfall even when annual expenses do not exceed annual income.
To prepare for payments due each quarter, school term or year, set aside their monthly equivalents. Moneysmart recommends setting money aside for quarterly or annual expenses, moving savings to a separate account to reduce the temptation to spend them, and setting reminders for upcoming bills. In this example, set aside 1,000,000 + 400,000 + 150,000 = VND 1,550,000 each month separately. This amount is sufficient only after contributions have been made for a full payment cycle. If you start later, divide the remaining shortfall by the number of months before the due date.
Step 5: Balance your budget
The monthly budgeting framework below is this article’s approach, not the CFPB’s cash flow budget tool. It has three components:
- Net income: the amount received after deductions.
- Monthly equivalents of recurring obligations calculated in step 3.
- The remaining balance, allocated to variable spending, savings and a contingency reserve.
For example: 15,000,000 − 7,970,000 = VND 7,030,000 remaining. One possible allocation is VND 4,500,000 for variable spending, such as food and transport, VND 1,500,000 for savings and VND 1,030,000 for a contingency reserve. These allocations total VND 7,030,000.
Moneysmart describes a process of totaling income, listing expenses, including irregular costs and annual bills, comparing income with expenses, setting savings goals, and reviewing and adjusting the budget when income or bills change. It also recommends reviewing the budget each month to maintain its accuracy.
If your income varies from week to week, Moneysmart suggests calculating an average as a starting point.
If expenses exceed income
If the remaining balance is negative, review the budget systematically:
- Identify essential payments and those that can be reduced or postponed.
- Review unused recurring subscriptions that could be canceled.
- Ask providers whether due dates can be changed or payments divided into smaller installments.
- Check for payments counted twice because of recording errors. See the guide to managing income and expenses across multiple accounts.
Step 6: Keep the list up to date
- Monthly: compare planned amounts with actual spending and adjust the following month’s budget. Use the statement reconciliation guide when comparing records with statements.
- Whenever circumstances change: promptly update the table in step 2 if prices change, you switch plans, cancel a service or your income changes.
- Annually: review the full list, paying particular attention to annual payments that may be overlooked.
Summary
Identify recurring payments in your statements, record their frequencies and due dates, calculate monthly equivalents, set funds aside for quarterly and annual payments, and allocate the remaining budget.
