Managing Family Budgets with Bank Sub-Accounts: A Practical Step-by-Step Guide

When we talk about improving personal money management, we often think of Excel spreadsheets or dedicated apps. But in recent years, some banks have started offering sub-accounts within your main account – a real opportunity to split money without needing separate accounts.

What are sub-accounts and why are they worth trying?

A sub-account is a section within your bank account with a dedicated number or name set by the customer. The idea is simple: whatever you want to allocate – such as household expenses, emergency savings or a travel goal – is moved to a sub-account with its own balance, but all of this remains under the same main account number.

The main advantage is that the bank remains the sole intermediary, reducing the complexity of linking multiple accounts under the same name. Additionally, some banks provide periodic reports for each sub-account and allow you to set automatic rules for transferring money between them.

Steps to open a sub-account within your bank account

• Choose a bank that supports the feature. Not every bank offers sub-accounts. In Saudi Arabia, major banks such as Al Ahli Bank, Riyad Bank and Saudi Fransi Bank have begun adding them within their digital account services.
• Log in to the bank’s app. After logging in, look for the option “Manage Accounts” or “Sub-Accounts”. It is usually found in account settings or in the additional services section.
• Create a new sub-account. You will be asked to name the sub-account (for example: “Emergency Fund” or “Children’s Expenses”). Some banks allow you to enter a financial goal linked to the name to track progress.
• Set the transfer rules. You can set up an automatic monthly transfer from your salary to the sub-account based on a certain percentage (for example, 20% for savings). If the bank supports “IF-THEN” rules, you could, for instance: if the main balance is > 10,000 SAR, transfer 5% to a “Travel” account.
• Monitor performance. Via the dashboard, you will get charts showing how much each sub-account is being used and how close you are to reaching your set goals.

How to use sub-accounts to split the family budget

Suppose a family of four earns a monthly salary of 15,000 SAR. The goal is to distribute the money across three main categories: household needs, emergency savings, and a leisure/travel fund.

You can create three sub-accounts within the main account:

• “Home” – 70% of the salary (10,500 SAR)
• “Emergencies” – 20% of the salary (3,000 SAR)
• “Travel” – 10% of the salary (1,500 SAR)

Once the transfer rule is set, the bank will automatically move the specified percentages as soon as the salary arrives in the main account. This way, you don’t need to remember to transfer manually, and you avoid errors in distributing money.

If you notice the “Home” sub-account balance is approaching its minimum, you can temporarily adjust the rule to reduce the percentage or delay some non-essential expenses.

Real benefits of relying on sub-accounts

• Reducing financial errors. When each category has its own balance, the chances of overspending in a particular category are reduced.
• Easy tracking of savings goals. Bank reports show the achievement percentage for each goal, which helps maintain motivation.
• Improving transparency within the family. If you involve your spouse in setting up the accounts, it becomes easy to show where every penny goes.
• Lower transfer fees. All transfers within the bank are carried out free of charge or for a nominal fee, compared to transfers between different banks.

Tips to avoid falling into the trap of hidden fees

Although most banks do not charge fees for internal transfers, some may charge for:

• Issuing a dedicated sub-account card.
• Closing a sub-account before a certain period has elapsed.
• Using a sub-account to receive transfers from external banks.

Before activating the service, read the detailed terms or ask customer service about any potential fees. If the bank does not provide clear information, look for an alternative.

Real-life examples: Local success stories

A family in Jeddah created a sub-account called “Zakat” to allocate 2.5% of each salary to meet religious obligations. After one year, they had accumulated 18,000 SAR in the fund, which was easily transferred to charities via the app.

In Riyadh, a freelancer created a sub-account called “Emergency”, with an automatic transfer rule from each income receipt to the fund. Over six months, they saved 12,000 SAR to cover emergency expenses without manual intervention.

Which banks offer the best sub-account experience in the region?

According to user reviews and financial app ratings, three banks stand out:

• Al Ahli Bank. It allows unlimited sub-accounts, with detailed graphical reports and integration with budget planning apps.
• Riyad Bank. It offers the “Split Your Balance” feature with the ability to customise names and goals, and enables setting smart transfer rules.
• Saudi Fransi Bank. It displays each sub-account’s balance on the main screen and provides instant alerts when the balance approaches the minimum.

Choose the bank based on ease of use, service cost, and how well the app integrates with your daily financial tools.

Practical steps to successfully activate and manage sub-accounts

1. Define your financial goals precisely (for example: “Save 20,000 SAR for next year”).
2. Choose a fixed percentage of income to transfer automatically to each goal.
3. Use the bank’s app to set alerts when each sub-account reaches a certain limit.
4. Review monthly reports and adjust rules if needed to avoid liquidity shortages.
5. Take advantage of any reward offers or points when withdrawing or transferring money within the sub-accounts.

With practice, you will notice that this idea makes your budget clearer and reduces worry about unexpected expenses.

Conclusion

The bank sub-account is a simple but powerful tool for splitting money, improving transparency within the family, and strengthening saving habits. Choosing the right bank, setting transfer rules accurately, and reviewing reports regularly ensures you achieve your financial goals without needing complex tools or many programmes.
