The Real Cost of a Bad Hire in Vietnam (with Calculator)
A bad hire in Vietnam rarely shows up as a single line on the P&L. The salary is visible. The recruitment fee is visible. What is not visible is the work that was not done, the manager hours spent fixing it, and the months a seat stayed effectively empty. This guide breaks the cost of a bad hire into parts, shows a worked example in Vietnamese dong, and gives you a free calculator so you can use your own numbers.
The Real Cost of a Bad Hire in Vietnam (with Calculator)
A bad hire in Vietnam rarely shows up as a single line on the P&L. The salary is visible. The recruitment fee is visible. What is not visible is the work that was not done, the manager hours spent fixing it, and the months a seat stayed effectively empty. This guide breaks the cost of a bad hire into parts, shows a worked example in Vietnamese dong, and gives you a free calculator so you can use your own numbers.
Why a bad hire costs more than the salary you paid
Most companies count a failed hire as "salary paid for months that did not work out." That is the smallest part of the bill for senior roles. The larger part is what the role was meant to deliver: a sales pipeline, a stable team, a compliant plant, a client relationship. When the person is not right, those outcomes slip, and someone else has to absorb the gap.
There are two kinds of cost. Direct costs are cash you can find in accounting records. Hidden costs are real but spread across other budgets and people, so they are rarely added up. A fair estimate needs both.
We do not quote an industry-wide percentage here. Published rules of thumb ("a bad hire costs 1.5x salary") vary widely by source and role, and they do not reflect your company. Use your own inputs.
Direct costs: salary, benefits, recruitment fee, onboarding, severance
- Salary and benefits paid.Gross salary plus the employer's compulsory contributions (social, health and unemployment insurance, and the trade union fee) for every month the person was on payroll. See our guide to the total cost of an employee in Vietnam for how these add up.
- Recruitment fee or advertising cost.What you paid an agency, executive search firm or job board to find this person. Include internal recruiter time if you have a way to price it.
- Onboarding and training.Equipment, licences, induction, language or technical training, and travel for relocation or regional visits.
- Severance and termination costs.Notice pay, accrued leave, and any severance or mutual-termination payment. The amount depends on the contract, tenure and the grounds for ending it, so confirm with your legal adviser before you plan a separation.
- Replacement cost.The second recruitment fee, unless your agreement includes a replacement guarantee.
Hidden costs: productivity, morale, client impact, management time
- Lost productivity.A new hire who delivers only part of what the role needs still draws a full salary. Estimate the share of expected output actually delivered. The gap is a cost.
- Management time.Coaching, rework, extra meetings, HR and legal time. Multiply hours by the hourly cost of the managers involved.
- Vacancy cost.The months the role was empty before the hire, and again before the replacement starts. Estimate what a month of the role's output is worth.
- Team morale and turnover.Good people leave when they have to carry a weak colleague or work for a weak leader. This is hard to price; if you have seen a resignation linked to the hire, add the cost of replacing that person too.
- Client and revenue impact.Lost deals, delayed projects, damaged relationships. Enter a number only if you can point to specific accounts or projects.
Why the cost rises with seniority (staff, manager, C-level)
The cost grows with seniority for three reasons.
- Higher pay and higher fees.Salary, bonus and search fees scale with the role, so the direct costs are larger.
- Wider reach.A country manager or general director decides on budgets, hiring, partners and compliance. A poor decision there affects many people and many months.
- Longer replacement cycle.Senior searches take longer, so the vacancy cost, before and after the failed hire, is larger. This is why executive turnover cost is so much higher than the cost of losing a junior employee: when a leader leaves, customer relationships and know-how leave with them, and the team has to absorb the handover gap.
For FDI subsidiaries, there is a fourth factor: a regional head office is often relying on the local leader for market judgement it cannot check itself.
Free calculator: inputs, formula and a worked example
The calculator is a spreadsheet. You enter your own numbers; there are no built-in loss percentages.
Cost of bad hire = (S + C) x (1 - V) + R + O + T + P + M + U + X
Where:
S = salary paid during tenure;
C = employer contributions during tenure;
V = share of expected value the person actually delivered;
R = recruitment fee paid;
O = onboarding and training;
T = severance and termination;
P = replacement fee (0 if guaranteed);
M = management time;
U = vacancy cost;
X = team and client impact.
The first term counts only the part of pay that bought nothing. This avoids counting the same loss twice.
Worked example (illustrative assumptions, not market data). A sales director is hired at VND 100,000,000 gross per month and leaves after 6 months.
Item | Assumption | VND |
Salary paid (S) | 6 months × 100,000,000 | 600,000,000 |
Employer contributions (C) | About 12,385,000 per month × 6 | 74,310,000 |
Value delivered (V) | 50% of expected output | – |
Lost value of pay | (S + C) × (1 − 50%) | 337,155,000 |
Recruitment fee (R) | 25% of annual gross, 1,200,000,000 (assumed fee rate; actual rates vary) | 300,000,000 |
Onboarding and training (O) | Assumed | 30,000,000 |
Severance and termination (T) | Assumed none (probation exit) | 0 |
Management time (M) | 4 hours/week × 26 weeks × 600,000 per hour | 62,400,000 |
Vacancy cost (U) | 3 months × 50,000,000 of lost output | 150,000,000 |
Team and client impact (X) | Not quantified | 0 |
Total, with replacement guarantee (P = 0) |
| 879,555,000 |
Total if replacement is paid again (P = 300,000,000) |
| 1,179,555,000 |
In this example the cost is about 8.8 times the monthly gross salary, without counting any lost client revenue. Change one input, such as value delivered or vacancy months, and the answer moves a lot. That is the point: the calculator shows which inputs matter in your case.
How the numbers are calculated. Employer contributions of about VND 12,385,000 a month use the 2026 employer rates: social insurance 17.5% and health insurance 3% on a base capped at VND 50,600,000, unemployment insurance 1%, and a 2% union fee. The recruitment fee uses an assumed rate of 25% of annual gross salary; actual rates vary by firm, role and agreement. The share of value delivered, management time and vacancy cost are assumptions: replace them with your own. Our guide to the total cost of an employee in Vietnam explains each contribution line.

5 ways to reduce bad-hire risk
- Define the role by outcomes.Write down what success looks like at 90 days, 6 months and 12 months, and what budget, team and authority the person gets. Vague roles produce vague hires.
- Use structured interviews.Ask every finalist the same competency questions, score them against the same criteria, and compare scores before the discussion. This limits the pull of first impressions.
- Check references properly.Speak to former managers, not only to names the candidate provides. Ask for specific examples, results and reasons for leaving. Get the candidate's consent first and follow Vietnam's personal data rules.
- Design the probation period.Set clear goals, review dates and decision criteria in writing. Check the current Labour Code for the legal limits on probation length and pay for the role level.
- Agree a replacement guarantee.If you use a search firm, ask what is covered, for how long and under what conditions. A guarantee removes the second fee from the table above.
A search consultant who knows the market can also test fit before an offer is made: how the candidate has performed in comparable FDI settings, and how they work with a regional head office.
FAQ
How much does a bad hire cost in Vietnam?
It depends on salary, seniority, tenure and the value the person delivered. In the worked example above, a VND 100 million per month sales director who left after six months cost about VND 880 million. Use the calculator with your own numbers.
Is the recruitment fee part of the cost of a bad hire?
Yes. If the hire fails, the fee you paid did not produce a lasting result. If your agreement includes a replacement guarantee, the replacement fee may not apply, but the first fee is still part of the loss.
Why are executive mis-hires more expensive than staff mis-hires?
Pay is higher, decisions reach more people and budget, and replacement takes longer. Each of these adds to direct and hidden costs, and to executive turnover cost when the leader leaves.
How can I reduce the risk of a bad executive hire?
Define outcomes, use structured interviews, check references with former managers, set a clear probation plan and agree a replacement guarantee with your search partner.
