Lump Sum Social Insurance Calculator
How the One-Time (Lump-Sum) Social Insurance Withdrawal Is Calculated in Vietnam (Law 41/2024)
One-line answer: A one-time social insurance withdrawal (BHXH một lần) pays 1.5 months of your average contribution salary for every year you contributed before 2014, plus 2.0 months for every year from 2014 onward, so 20 years on a 12 million VND salary returns about 444 million VND in cash. The 2024 reform (Social Insurance Law 41/2024/QH15, effective 1 July 2025) kept that formula but tightened who can claim, and any years you contribute after 1 July 2025 can no longer be cashed out.
Built by HAPRI, the Health and Agricultural Policy Research Institute, an independent public-policy research institute in Vietnam. Legal basis: Social Insurance Law 41/2024/QH15 (Article 70, lump-sum amount and eligibility; Article 102, transition provisions), carrying forward the 1.5x / 2.0x split from Law 71/2014/QH13 amending Law 58/2014/QH13 (Article 60), with the pension comparison drawn from Articles 66, 67 and 72.

1. Quick answer
If you leave Vietnam's social insurance system before you qualify for a pension, you can claim a single cash payout instead of a future monthly pension. The amount is 1.5 months of average contribution salary per year contributed before 2014, plus 2.0 months per year contributed from 2014 onward, multiplied by your average contribution salary. Someone with 6 pre-2014 years and 14 later years on a 12,000,000 VND average salary receives 444,000,000 VND (37 months of salary) in a lump sum. The calculator above also shows the alternative: the monthly pension those same years would unlock at retirement, and the break-even year at which the pension stream overtakes the invested lump sum. Under the 2024 reform, any contribution time after 1 July 2025 is locked into the pension track and cannot be withdrawn, and the routine "12 months unemployed" withdrawal route is closed to anyone who first joined on or after that date.
2. How the lump-sum is calculated, step by step
The amount uses a two-rate formula that splits your career at the year 2014. The calculator above runs exactly these steps.
- Take your average monthly contribution salary (bình quân tiền lương tháng đóng BHXH), the average of the salary your contributions were based on over your career.
- Count your contribution years before 2014. Each of these years is worth 1.5 months of that average salary (under Law 58/2014/QH13 Article 60, carrying forward the legacy rate from Law 71/2006/QH11).
- Count your contribution years from 2014 onward. Each of these is worth 2.0 months of average salary (the rate set by Law 58/2014/QH13 and preserved by Law 41/2024/QH15).
- Add the two pieces together. That total, in months of salary, multiplied by your average salary, is your one-time payout.
The formula:
The pension comparison. Choosing the lump sum forfeits any future pension, so the calculator models the other path too. If you instead keep your years and claim a pension at retirement, your monthly pension is a replacement rate times your average salary (Section 3). The tool then projects two streams forward:
The break-even year is the first year N at which the cumulative pension catches up to the invested lump sum. With the default assumptions (pension uprating 8% a year, lump-sum return 5% a year), the pension typically overtakes the cash within five to eight years for a pension-eligible worker. Both assumption sliders sit inside the chart so you can test your own numbers; set them both to 0% for a pure nominal comparison.
3. Rates, parameters and thresholds
All values below are baked into the calculator and link to the authentic government text in Section 8.
The two withdrawal rates
- Years contributed before 2014: 1.5 months of average salary · Law 41/2024/QH15 Art. 70 (legacy 1.5x rate)
- Years contributed from 2014 onward: 2.0 months of average salary · Law 71/2014/QH13 amending Law 58/2014/QH13 Art. 60; preserved by Law 41/2024/QH15 Art. 70
Partial years are pro-rated and capped at 2 months of average salary per year.
The reform cutoff
- Post-reform lockout date: 1 July 2025 · Contribution time after this date is locked into the pension track and cannot be cashed out · Law 41/2024/QH15 Art. 70 + Art. 102
Pension comparison parameters (the "if you wait" path)
- Minimum years to qualify for a pension: 15 years (reduced from 20 under the old law) · Law 41/2024/QH15 (effective 1 July 2025)
- Replacement-rate base: 45% of average salary · Law 41/2024/QH15 Art. 66
- Replacement-rate increment: +2% per year above the anchor · Law 41/2024/QH15 Art. 66
- Replacement-rate ceiling: 75% · Law 41/2024/QH15 Art. 66
- Female anchor / years to the cap: 15 years anchor · 30 years to reach 75% · Law 41/2024/QH15 Art. 66
- Male anchor / years to the cap: 20 years anchor · 35 years to reach 75% · Law 41/2024/QH15 Art. 66
- Male transitional band (15 to 19 years): 40% + 1% per year above 15 · Law 41/2024/QH15 Art. 66 (new transitional rate)
How the replacement rate is read. A woman reaches the 45% base at 15 years and adds 2% for every further year, hitting the 75% ceiling at 30 years. A man with 20 or more years starts at 45% and adds 2% a year, reaching 75% at 35 years; a man with only 15 to 19 years sits on a transitional 40% plus 1% per year. The pension is then that rate times the average salary.
Time-value assumptions (you can change these)
- Pension uprating: 8% a year · Roughly the 10-year average of Vietnam's pension increases · Law 41/2024/QH15 Art. 67 (periodic uprating)
- Lump-sum return if invested: 5% a year · A conservative Vietnamese bank term-deposit rate · Term-deposit reference, 2026
4. Worked examples
Each example follows a real person through the full calculation. The figures are the exact output of the calculator above, using its default assumptions (pension uprating 8% a year, lump-sum return 5% a year) where the pension comparison applies.
One thing to keep in mind: the lump sum is always based on your average contribution salary, not your final salary. If your salary rose over your career, your average is lower than your last payslip, so the cash figure is lower than a quick “last salary × months” estimate. The calculator uses the average, exactly as the law requires.
Example A: Mai, a nurse emigrating to join family abroad
Mai contributed to social insurance for 10 years on an average salary of 8,000,000 VND a month: 3 of those years fell before 2014 and 7 from 2014 onward. She is moving permanently abroad and will not contribute again, so she qualifies under the permanent-emigration trigger.
Inputs: average salary 8,000,000 VND/month · 3 years pre-2014 · 7 years from 2014 · total 10 years.
Mai receives 148,000,000 VND in a single payout. With only 10 contribution years she is below the 15-year pension floor, so there is no pension alternative to weigh against — the lump sum is genuinely her best route to recover her contributions before she leaves.
Basis: Law 41/2024/QH15 Art. 70 (1.5× / 2.0× amount; permanent-emigration trigger).
Example B: Lan, a factory worker with a long record, deciding whether to cash out
Lan has 20 contribution years on an average salary of 12,000,000 VND a month: 6 years before 2014 and 14 from 2014 onward. After a year out of work she is tempted to withdraw, but she wants to see what she would give up.
Inputs: average salary 12,000,000 VND/month · 6 years pre-2014 · 14 years from 2014 · total 20 years · female.
Lan can take 444,000,000 VND now, or a pension of 6,600,000 VND a month that repays the lump sum within about six years and keeps paying for life.
Basis: Law 41/2024/QH15 Art. 70 (amount); Art. 66 (55% replacement rate); Art. 67 (uprating).
Example C: Tuan, a male office worker at the pension anchor
Tuan has 20 contribution years on an average salary of 15,000,000 VND a month: 5 years before 2014 and 15 from 2014 onward. He is exactly at the male 20-year pension anchor and wants the full picture.
Inputs: average salary 15,000,000 VND/month · 5 years pre-2014 · 15 years from 2014 · total 20 years · male.
Tuan can take 562,500,000 VND now, or a 6,750,000 VND monthly pension that repays the cash within about eight years. Because he is on the 45% base rather than a higher rate, his break-even is a little later than Lan's — exactly the trade-off a man at the 20-year anchor faces.
Basis: Law 41/2024/QH15 Art. 70 (amount); Art. 66 (45% base replacement rate); Art. 67 (uprating).
5. Frequently asked questions
What is the formula for the one-time social insurance withdrawal in Vietnam?
The payout is 1.5 months of your average contribution salary for each year you contributed before 2014, plus 2.0 months for each year from 2014 onward, all multiplied by your average contribution salary. For example, 6 years before 2014 and 14 years after, on a 12,000,000 VND average salary, gives (1.5 × 6 + 2.0 × 14) × 12,000,000 = 37 months × 12,000,000 = 444,000,000 VND. The rates come from Law 41/2024/QH15 Article 70, carrying forward the earlier 1.5x and 2.0x rates.
Should I withdraw my social insurance as a lump sum or wait for a pension?
It depends on your situation. If you are emigrating permanently or will never contribute again, the lump sum recovers your money. But if you can reach the 15-year floor, the pension is usually worth far more over time: in the calculator's examples the monthly pension repays the entire lump sum within roughly five to eight years and then keeps paying for life, with periodic increases on top. Use the break-even line above with your own salary, uprating and investment-return assumptions to see where the crossover falls for you.
What changed under the 2024 Social Insurance Law about lump-sum withdrawals?
Law 41/2024/QH15, effective 1 July 2025, kept the amount formula unchanged but tightened access. Contribution time accrued after 1 July 2025 is locked into the pension track and can no longer be cashed out. Anyone who first joins social insurance on or after that date also loses the routine "12 consecutive months unemployed" withdrawal route, keeping only the hardship triggers. People who were already contributing before 1 July 2025 keep all of their previous withdrawal rights.
When can I withdraw my social insurance as a lump sum?
If you began contributing before 1 July 2025, you can withdraw under any of six triggers: reaching retirement age with under 15 years contributed; permanent emigration; terminal illness; loss of working capacity of 81% or more; 12 consecutive months outside mandatory and voluntary social insurance with under 20 years contributed; or military discharge without pension eligibility. If you first joined on or after 1 July 2025, the 12-month-unemployment route is closed and only the five hardship triggers remain. The calculator's "when can I withdraw?" panel lays this out by start date.
How many years do I need to qualify for a pension instead?
15 years. The 2024 reform reduced the pension floor from 20 years to 15 (effective 1 July 2025), which is one of its most important changes. Many workers who once had to take a lump sum because they could not reach 20 years can now wait and draw a pension instead. In the calculator, if your total years are below 15 the pension comparison is hidden, because there is no pension to compare against; at 15 years and above, the comparison and break-even line appear.
Is the lump sum based on my final salary or my average salary?
Your average contribution salary across your whole career, not your final salary. Because most people's salaries rise over time, the average is lower than the last payslip, so a quick "last salary times months" estimate overstates the payout. The calculator uses the average, which is what the law applies. If you are unsure of your average, your social insurance book (sổ BHXH) records the salary your contributions were based on for each period.
Why are years before 2014 worth less (1.5 months) than later years (2.0 months)?
The two rates are a legacy of how the law evolved. Years contributed before 2014 are valued at the older 1.5-months-per-year rate, while years from 2014 onward use the 2.0-months-per-year rate introduced by Law 58/2014/QH13 (as amended by Law 71/2014/QH13). Law 41/2024/QH15 preserved both rates rather than flattening them, so a long career that straddles 2014 is split into a 1.5x portion and a 2.0x portion, exactly as the calculator shows in the two-color breakdown bar.
Can I still withdraw the years I contribute after July 2025?
No. Under Law 41/2024/QH15, contribution time accrued from 1 July 2025 onward is reserved for the pension and cannot be taken as a lump sum. Only your contributions up to that date count toward a withdrawal. This is the single biggest practical change for current workers: the longer you keep contributing after the cutoff, the larger the pension-only portion of your record becomes, which the calculator reflects by limiting the withdrawable years to your pre-cutoff contributions.
6. Common scenarios and edge cases
- You joined before 1 July 2025 (most current workers). You keep all six withdrawal triggers, including the routine "12 months unemployed with under 20 years" route. Your contribution time up to the cutoff is withdrawable; time after it is pension-only.
- You first joined on or after 1 July 2025. The 12-month-unemployment route is closed to you. You can only withdraw under the five hardship triggers (retirement age with under 15 years, permanent emigration, terminal illness, 81%+ work-capacity loss, or military discharge without pension).
- You are below the 15-year pension floor. There is no pension to weigh against, so the lump sum is the only way to realize your contributions. The calculator hides the pension comparison in this case (as in Example A).
- You are at or above 15 years. Both paths are open. The break-even line shows when the pension overtakes the invested lump sum; for most pension-eligible records this is within five to eight years under the default assumptions.
- Your whole career is after 2014. The 1.5x portion is zero and the entire payout uses the 2.0x rate, so the breakdown bar shows a single segment.
- You contributed before 1995. Mandatory social insurance for the private sector began in 1995; state employees were covered earlier. The calculator's pre-2014 slider is grounded in realistic private-sector scenarios, but the underlying math handles any number of pre-2014 years correctly.
- Time value matters. The lump sum is cash today; the pension is a stream that is periodically uprated. Setting the uprating and return sliders to 0% shows the pure nominal comparison; the defaults (8% and 5%) reflect Vietnam's historical pension increases and a conservative deposit rate.

9. Methodology, scope and disclaimer
This page and the calculator above model the one-time social insurance withdrawal under Law 41/2024/QH15 (effective 1 July 2025) for the common case: a worker who contributed to mandatory social insurance and is deciding between a cash withdrawal and a future pension. The amount uses the 1.5x (pre-2014) and 2.0x (from-2014) rates on average contribution salary; the pension comparison uses the replacement-rate schedule in Article 66 and projects both flows forward under user-set uprating and investment-return assumptions.
It does not model voluntary social insurance buy-back, occupational-disease or work-injury benefits, survivor benefits, or the precise look-back averaging window for pensionable salary (which varies by start year under Article 72). It assumes a single, continuous contribution record and treats the pre-2014 / from-2014 split as whole years; real records with mid-year transitions are pro-rated by the social insurance agency.

10. About this calculator
HAPRI (the Health and Agricultural Policy Research Institute) builds free, openly-documented tools to make Vietnamese public policy legible to the people it affects. This calculator is part of a suite of seven covering personal income tax, take-home pay, pensions and social insurance. The lump-sum-versus-pension decision is one of the most consequential financial choices a Vietnamese worker makes, and one where the long-term cost of cashing out is easy to underestimate, so the tool is built to show both sides without steering you toward either. The math is version-controlled, tested against the primary law, and refreshed from a live constants database, so the figures here stay in step with the statute as it changes.
