Calculating the one-time social insurance payout for foreigners who leave their jobs in Vietnam sounds simple, yet a single misunderstanding about the number of contribution years or the average salary can leave you tens of millions of dong short, or get your application rejected right at the social insurance office. For money accumulated over years of work, a small error in the calculation is more than just a figure on paper.
You are about to end your contract and leave Vietnam, but you are unsure how much the social insurance you have paid all this time will amount to. How many months of salary is each contribution year multiplied by, and which salary is actually used for the calculation? If you only learn of your right to withdraw after returning home, will that money still be intact? These are the doubts that make many foreign workers hesitate, only to spend months redoing their paperwork. This article analyzes how current law determines the benefit amount, the steps to follow, and the common mistakes that leave you short-changed or delay your application.
Eligibility for foreigners to withdraw a one-time social insurance benefit upon leaving a job
Before turning to the numbers, you need to determine whether you are eligible to withdraw. Under the Law on Social Insurance 2024, effective 01 July 2025, a foreign national working in Vietnam is subject to compulsory social insurance when signing a fixed-term labor contract of 12 months or more, save for a few cases such as intra-corporate transfers or having already reached retirement age at the time of signing. In other words, if you have been working and have had insurance deducted from your monthly payslip, you almost certainly have a balance accumulated in the fund.
The key point for foreigners is that you do not have to wait 12 months after leaving your job, as Vietnamese employees do. The law lets you withdraw a one-time social insurance benefit as soon as the labor contract terminates, or when the work permit, practice certificate, or practice license expires without renewal.
Beyond leaving a job, foreigners may also withdraw a one-time benefit if they reach retirement age without 15 years of contributions, are suffering from one of the listed illnesses (cancer, paralysis, decompensated cirrhosis, severe tuberculosis, AIDS), have a working-capacity reduction of 81% or more, or are eligible for a pension but no longer reside in Vietnam. For most people leaving Vietnam after their contract ends, the basis for withdrawal is the contract termination described above.
How to calculate the one-time social insurance benefit for foreigners
The one-time social insurance benefit is calculated using a fairly clear formula: multiply the number of contribution years by the number of months granted for each year, then multiply by the average monthly salary on which social insurance was based. The number of months granted per year is set by the law at two rates.
For foreigners, this is good news arithmetically. Contributions to the retirement and survivorship fund, the part that forms the basis for the one-time benefit, only began to apply to foreign workers from 2022. Your entire contribution period therefore falls within the period from 2014 onwards, so each year of contribution is counted at 02 months of average salary, the higher of the two rates above.
What about the odd months that do not complete a full year? The law handles them in a way that favors rounding up.
Average salary and the adjustment coefficient
The second factor, and where many people miscalculate, is the average salary. Foreigners work under a salary scale set by the employer, so the average is calculated over the entire contribution period, not just the final few years. More importantly, the salary for each year is not taken at its nominal figure, but is multiplied by an adjustment coefficient (often called the inflation index) published annually by the social insurance agency based on the consumer price index. This coefficient is always 1 or higher, meaning the further back a contribution year is, the more its salary is scaled up in the calculation, keeping the amount you receive from being eroded over time.
An illustrative example
To picture it, suppose a foreigner has paid social insurance for 3 years and 6 months, with an average monthly salary of 50 million dong after applying the adjustment coefficient. The six odd months count as half a year, so the number of contribution years is 3.5. Since the entire period falls after 2014, each year is granted 02 months of salary: 3.5 multiplied by 2 equals 7 months. The estimated benefit is roughly 7 multiplied by 50 million, that is 350 million dong. If you have contributed for less than one year, the benefit equals the exact amount paid, but no more than 02 months of the average salary.
It should be stressed that this is only an illustration of the method. The actual figure depends on the salary in each year, the adjustment coefficient applied when you receive the benefit, and the exact contribution period recorded in your social insurance book. That is why reviewing your contribution history before filing is no less important than knowing the formula.
Procedures and documents for withdrawing a one-time social insurance benefit
As for paperwork, the law prescribes a fairly compact application file for a one-time social insurance benefit: the social insurance book and the employee's written request. However, to reach that filing step smoothly, in practice you usually have to go through the following steps in order:
- Finalize the social insurance book at the unit you have just left. If you previously worked elsewhere during a period that was never finalized, that period must also be fully finalized in order to count the correct number of contribution years.
- Review and adjust the information in the social insurance system so that it matches your passport, particularly your full name and identification number, before filing.
- Prepare the file comprising the social insurance book and the written request for the one-time benefit. If you are abroad, you will also need a valid power of attorney for the person carrying out the procedure in Vietnam.
- Submit the file to the competent social insurance agency and monitor the processing.
- Receive the money in your account. If you are no longer in Vietnam, this is the point at which you transfer the funds to your account abroad in accordance with regulations.
For those who have already returned home, you are not required to fly back. The power of attorney can be executed at a Vietnamese representative mission abroad (the Embassy or Consulate General), then sent to Vietnam for the authorized person to complete the procedure on your behalf.
Common risks and mistakes when calculating and withdrawing social insurance
First, let us clear up a rumor that worries many people: that after withdrawing a one-time social insurance benefit, you will be barred from returning to work in Vietnam for a period, and may even be asked to repay the money if you do return. Having reviewed the Law on Social Insurance 2024 and Decree 158/2025/NĐ-CP guiding its implementation, there is no provision imposing any such restriction. Having taken a one-time benefit simply means that period of contribution has been paid out and will not be counted again toward future entitlements; it does not prohibit you from returning to work in Vietnam and contributing anew.
The real risk lies in the paperwork and the calculation, not in the right to withdraw. The most common obstacles in practice include:
- The social insurance book cannot be finalized, especially when a former employer has ceased operations or is entangled in legal issues. This is a difficult situation, but not a dead end if you work directly with the social insurance agency that once managed that unit.
- The information in the system does not match the passport, causing the file to be returned for correction before it can be processed.
- No longer having a bank account in Vietnam to receive the money after departing, so that the approved amount has nowhere to be paid.
- Miscalculating the amount by ignoring the adjustment coefficient, misunderstanding the average salary, or forgetting how to convert odd months, leading to expectations that differ from what is actually received.
Another mistake is a matter of timing: leaving Vietnam in too much of a hurry without having signed a service contract and executed a power of attorney. Once you are abroad, everything can still be done, but it will involve the additional step of legalizing documents and take more time than handling it neatly before your flight.
How DEDICA supports foreigners in withdrawing a one-time social insurance benefit
DEDICA supports foreigners through the entire one-time social insurance withdrawal procedure: reviewing eligibility and calculating the potential amount in advance so you are not caught off guard, preparing the file, finalizing the book, adjusting information to match your passport, and filing and working with the social insurance agency until the money reaches your account. For outstanding files such as a book that cannot be finalized because a former employer is entangled in legal issues, we work directly with the managing social insurance agency to resolve them.
If you are about to fly or have already returned home, DEDICA arranges to sign the service contract and execute the power of attorney in time to handle everything remotely, guides you in executing a power of attorney at a Vietnamese representative mission abroad, helps open an account to receive the money when you no longer have one in Vietnam, and carries out the transfer of funds abroad under the power of attorney. The goal is for you to receive exactly and fully what you are entitled to, even when you are not present in Vietnam.
Conclusion
If you are a foreigner leaving a job in Vietnam, remember four things. First, you may withdraw a one-time social insurance benefit as soon as your contract terminates, without waiting 12 months. Second, the benefit equals the number of contribution years multiplied by 02 months of average salary for each year (since a foreigner's entire contribution period falls after 2014), where odd months of 1 to 6 count as half a year, 7 to 11 count as a full year, and each year's salary is multiplied by the adjustment coefficient. Third, the file comprises only the social insurance book and the written request, but the book must be finalized and the information must match your passport before you can file. Fourth, if you have already left or are about to leave Vietnam, execute a power of attorney so that someone in Vietnam can act on your behalf rather than flying back. The three errors that most often prolong a file are an unfinalized book, information that does not match the passport, and no account to receive the money, so address these three points first.
Every foreigner's social insurance file has its own particulars regarding the contribution period, job history, and current place of residence. If you want to know exactly how much you are entitled to and what to do before leaving Vietnam, contact DEDICA to have a lawyer review your contribution history, calculate the amount in advance, and accompany you until the money reaches your account, even when you are abroad.
