Quick Summary

Retention Rate is commonly used to measure how well a company retains its employees. However, if companies only look at Retention Rate at the organization-wide level, they may miss a more serious risk: losing the people they cannot afford to lose.

For senior executives, key talents, and business-critical roles, one resignation does not only reduce Retention Rate. It can create significant replacement costs, including executive search fee, vacancy period, transition cost, onboarding time, learning curve, operational disruption, and the risk of losing momentum across the team.

In many HR and talent discussions, the cost of replacing a senior executive is often estimated at 100%–150% of the executive’s annual salary, depending on the role level, industry, talent scarcity, vacancy duration, and business impact of the position. This should be read as an estimate rather than a fixed benchmark for every company.

Concept	What it means for the business
Retention Rate	The percentage of employees a company retains over a specific period
Regrettable Turnover Rate	The turnover rate of employees the company does not want to lose
Key Talents	Critical employees who strongly affect operations, growth, or competitive advantage
Executive Turnover Cost	The total financial and non-financial cost of losing a senior executive
Talent Risk Management	A system for identifying and managing the risk of losing key talents before it is too late

1. Why Retention Rate Should Not Be Measured Equally Across the Organization

1.1. Organization-wide Retention Rate can hide key talent risk

Many companies measure Retention Rate in a simple way: they look at how many employees remain during a period compared with the original employee base.

This metric is useful. It gives HR and business leaders a general picture of workforce stability. However, organization-wide Retention Rate does not always reflect the real talent risk inside the business.

A company may report a healthy Retention Rate while still losing a critical COO, Plant Manager, Sales Director, HR Director, or Finance Director during the same period. From a purely numerical perspective, the overall Retention Rate may not look alarming. From a business perspective, the damage can be significant.

Not every resignation carries the same weight. Losing an easily replaceable role is different from losing a senior executive who owns operations, strategy, major clients, transformation projects, or a high-performing team.

This is why Retention Rate can be misleading when it is measured too broadly. The more important question is not only “how many people stayed,” but “did the company keep the people it could not afford to lose?”

1.2. Regrettable Turnover Rate should be tracked together with Retention Rate

From a strategic talent management perspective, companies should not stop at Retention Rate. They should also monitor Regrettable Turnover Rate, which refers to the turnover of employees whose departure creates real loss for the organization.

This usually includes high performers, key talents, succession candidates, critical role holders, and senior leaders who directly affect business outcomes.

If Retention Rate answers the question, “How many employees did we retain?”, Regrettable Turnover Rate answers a more important question: “Are we losing the people who matter most?”

At executive level, this distinction is critical. A small turnover rate among key talents can create a much greater business impact than a higher turnover rate in roles that are easier to replace.

1.3. Retention Rate should be treated as a business risk indicator

Retention Rate should not only be an HR metric reported quarterly or annually. For companies that are expanding, entering new markets, transforming operations, or building a stronger leadership team, Retention Rate should be treated as an indicator of business risk.

When a senior executive leaves, the company does not only lose a person on payroll. It may lose decision-making speed, team stability, client confidence, operational continuity, or the ability to execute strategic initiatives.

This is why companies should segment Retention Rate by role type. Executive team Retention Rate, key talent Retention Rate, critical role Retention Rate, and succession talent Retention Rate may reveal risks that the overall number cannot show.

2. Retention Rate and Financial Cost: How Expensive Is It to Replace a Senior Executive?

2.1. A simple financial example from a COO role

Let’s look at Retention Rate from a financial cost perspective.

If a Chief Operating Officer has a monthly salary of VND 150 million, the annual salary is approximately VND 1.8 billion. If the cost of replacing a senior executive is estimated at 100%–150% of annual salary, the potential cost of losing this COO could range from VND 1.8 billion to VND 2.7 billion.

This is an illustrative calculation, not a fixed figure for every business. The real cost depends on the industry, availability of qualified candidates, search timeline, vacancy duration, transition complexity, and the level of business impact attached to the role.

Still, the example shows one important point: when a company loses a senior executive, the cost is not limited to salary or recruitment expense. It can affect cash flow, operational speed, strategic execution, and business continuity.

For companies hiring senior leaders in Vietnam, compensation decisions should also be understood in connection with replacement risk. TalentsAll has discussed this broader perspective in its article on executive compensation in Vietnam, where senior leadership offers need to balance market competitiveness, internal equity, and business impact.

2.2. Low Retention Rate among executives can create hidden costs

When Retention Rate drops among executives or key talents, the costs are often not captured in one visible budget line. Companies may see the executive search fee, replacement hiring cost, or new hire salary. But many other costs are absorbed quietly into day-to-day operations.

For example, when a COO leaves, operational decisions may slow down. Projects that require executive approval may be delayed. Department heads may need to take on temporary responsibilities. The team may become uncertain about direction, priorities, and future leadership.

These losses may not always appear as direct expenses in financial reports. But they still reduce business performance.

This is why Retention Rate for senior executives should be read together with replacement cost, time-to-fill, vacancy period, and operational disruption.

2.3. Executive replacement cost is not only recruitment cost

A common mistake is to view the cost of replacing a senior executive as only a recruitment cost. In reality, executive turnover cost is much broader.

Companies may need to pay executive search fee, assessment cost, interview cost, onboarding cost, and transition cost. They may also face the cost of a learning curve, because a new executive needs time to understand the company’s culture, systems, stakeholders, people, and unresolved issues.

This is why Retention Rate should not be separated from executive search strategy. In a previous TalentsAll article, we discussed why salary benchmarking in executive search is an important step before approaching the market. The same logic applies to retention: companies need to understand market expectations before they lose key people, not only after a resignation happens.

3. Retention Rate and Executive Turnover Cost: Where Does the Money Go?

3.1. Direct costs after a senior executive leaves

When a senior executive leaves, the company usually sees some direct costs first. These may include executive search fee, assessment cost, interview cost, internal hiring coordination, and the cost of temporary replacement or internal coverage.

During the vacancy period, the company may need to assign other leaders to cover part of the role. This creates additional pressure on the current team and may slow down strategic work.

For senior roles, direct costs are only the most visible part. The more serious cost is often hidden behind business disruption.

3.2. Opportunity cost and operational disruption

A senior executive departure can create a decision-making gap for three to six months, or even longer if the role is difficult to replace.

During that period, strategic decisions may be delayed. Projects may be paused. Teams may lack direction. Cross-functional coordination may become slower. In some cases, business units may wait for a new leader before making major decisions.

For roles such as COO, Plant Manager, Finance Director, Sales Director, HR Director, or Country Manager, this opportunity cost can be much larger than the direct executive search fee.

3.3. Performance cost and the domino effect

Even after a replacement is hired, the new executive needs time to reach full performance. They need to understand the operating model, leadership culture, internal stakeholders, team dynamics, and unresolved business issues.

In many cases, a senior executive may need six to nine months to fully understand the organization and operate at maximum effectiveness. During that time, the company pays 100% of the compensation package, while the contribution may not yet reach 100%.

There is also a domino effect. When a strong leader leaves, the team may become uncertain. Loyal employees may question the future direction of the function. High performers may start evaluating external opportunities if they feel leadership continuity is weak.

This is why Retention Rate among key talents should be monitored before the issue spreads.

Cost category	Business impact
Direct costs	Executive search fee, assessment cost, interview cost, internal coverage cost
Opportunity cost	Slower decisions, delayed projects, weaker execution speed
Onboarding cost	New executive needs time to understand the business and reach full performance
Team impact	Lower morale, weaker trust, higher risk of follow-on resignations
Strategic disruption	Loss of continuity in growth, transformation, or market expansion initiatives

4. Why Counter-Offers Do Not Always Improve Retention Rate Effectively

4.1. Counter-offers are often a late response to Retention Rate risk

When a key person begins to show signs of leaving, many companies respond with a counter-offer. This usually means increasing salary, offering a retention bonus, or making short-term adjustments to persuade the person to stay.

In some cases, a counter-offer may work temporarily, especially if the main reason for leaving is compensation. However, if the real reason is lack of authority, loss of trust, long-term pressure, weak relationship with the line manager, unclear career path, or limited influence, a salary increase only treats the symptom.

Retention Rate cannot be improved sustainably if the company only reacts when the employee is already prepared to leave. By that point, trust may have already declined. A higher salary may delay the departure, but it may not solve the root cause.

4.2. Sudden salary increases can distort compensation structure

Counter-offers can also create internal risk. If a key person receives a major salary adjustment only after showing intent to resign, other employees may learn that the fastest way to be recognized is to create exit pressure.

This weakens internal equity and makes the compensation system more reactive than strategic.

At executive level, the risk is even higher. A sudden compensation increase for one key person can affect the broader leadership compensation structure, especially if the company does not have market data or a clear business rationale to justify the decision.

This is why counter-offers should not be the main tool for improving Retention Rate. Companies need a more proactive system to identify the risk of losing key talents before they decide to leave.

4.3. Retention Rate should be managed before a resignation happens

If a company only looks at Retention Rate after resignations are submitted, most of the intervention window has already been missed.

For key talents, warning signs often appear earlier: lower participation in strategic discussions, reduced initiative, less interaction with the line manager, hesitation to commit to long-term projects, or increased interest in external opportunities.

These signals cannot be detected by reviewing Retention Rate at the end of the quarter. They require a more proactive talent risk management system.

This also connects with compensation negotiation. When a key person is already in the market, the company may be forced into reactive negotiation. TalentsAll has discussed this issue in its article on how to negotiate compensation with senior candidates, where a strong offer should be built on market data, role clarity, internal equity, and trust.

5. How Companies Can Improve Retention Rate Through a Key Talent Retention Ecosystem

5.1. Total Rewards supports a more sustainable Retention Rate than base salary alone

Key talent retention cannot rely only on base salary. At senior level, employees evaluate the total value of what the company offers: salary, bonus, long-term incentives, family benefits, decision-making authority, scope of influence, recognition, and career impact.

An effective Total Rewards system may include competitive base salary, performance-based bonus, long-term incentives, ESOP if suitable, premium health insurance, flexible benefits, and recognition mechanisms.

The important point is that Total Rewards should not be designed as a one-size-fits-all package. For key talents, companies need to understand the motivation of different groups. Some leaders need a clearer promotion path. Some need broader authority. And the others need the opportunity to lead strategic initiatives.

When Total Rewards is designed properly, Retention Rate improves not only because people are paid more, but because they feel fairly recognized and see a future in the organization.

5.2. Career Path gives key talents a reason to stay

Senior leaders do not stay only for compensation. They stay when they can see the bigger picture.

At executive level, Career Path is not only about the next title. It is about influence, decision-making authority, strategic role, business mandate, and the opportunity to leave a meaningful impact.

If a key person no longer sees a future in the company, Retention Rate may begin to decline even when the current compensation package remains competitive. On the other hand, if they believe their role matters in the company’s next stage of growth, the company has a stronger chance of retaining them.

This means key talent retention must include strategic dialogue. Companies need to understand how senior leaders want to grow, what they expect from the next stage of their role, and whether they still believe in the organization’s direction.

5.3. Talent Risk Management helps companies manage Retention Rate proactively

Talent Risk Management helps companies move from “trying to retain people when they want to leave” to “identifying talent risk before it becomes too late.”

Instead of waiting for a resignation letter, HRBPs and line managers should build early warning indicators. These may include engagement level, interaction frequency with leadership, workload pressure, behavior changes, participation in strategic projects, and succession readiness for critical roles.

A strong Talent Risk Management system helps the company answer three questions:

• Who are the people the company cannot afford to lose?
• What is the current risk level for each key person?
• Should the intervention focus on career path, total rewards, workload, authority, leadership communication, or succession planning?

When Retention Rate is managed this way, the company is not only measuring the past. It is managing future talent risk.

6. How TalentsAll Supports Companies in Reviewing Retention Rate and Talent Risk

6.1. From executive search to talent advisory

TalentsAll does not only support companies when a senior role becomes vacant. For strategic talent challenges, TalentsAll helps companies understand the senior talent market, executive expectations, salary market insight, and replacement risk for business-critical roles.

When Retention Rate among executives or critical roles becomes unstable, companies need to review multiple factors at the same time: whether the compensation package remains competitive, whether career path is clear, whether the role has enough authority, whether the leadership team is stable, and whether a suitable successor exists.

This is where executive search, salary benchmarking, talent mapping, and HR consulting come together.

6.2. When should companies review their Retention Rate?

Companies should review Retention Rate when the overall number looks stable but the leadership team begins to show signs of instability.

This situation is common. The overall Retention Rate may not look problematic, but the most important people may already be disengaged, under pressure, or open to external opportunities.

Warning signs include repeated resignations among key people, frequent counter-offers, critical roles without successors, long timelines to replace senior leaders, or strategic projects slowing down because there is no clear owner.

In these cases, Retention Rate should be reviewed together with market data, compensation structure, succession planning, and key talent engagement.

6.3. TalentsAll helps companies manage talent risk before it becomes too costly

If a company only turns to executive search after a key person has already left, the problem is usually more expensive. The company must find a replacement, manage the leadership gap, protect team morale, and restore confidence in the function.

A more proactive approach is to assess talent risk before losing key people. TalentsAll can support companies in reviewing the senior talent market, target candidate expectations, compensation competitiveness, and replacement readiness for critical roles.

For companies that are expanding, transforming, or competing strongly for senior talent, managing Retention Rate among key talents is not only an HR responsibility. It is part of sustainable business growth.

Conclusion

Retention Rate is an important metric, but when measured too broadly, it can hide the real risk: losing the people the company cannot afford to lose.

For executives and key talents, one resignation can create significant replacement cost. This cost does not only include executive search fee or replacement salary. It also includes vacancy time, learning curve, operational disruption, slower decision-making, and a possible domino effect across the team.

This is why companies need to move from measuring general Retention Rate to managing Regrettable Turnover Rate among key talents. Instead of reacting with counter-offers when a key person is already leaving, companies need a retention ecosystem built on Total Rewards, Career Path, and Talent Risk Management.

TalentsAll supports companies in Vietnam with executive search, senior recruitment, salary market insight, strategic talent mapping, and talent advisory for senior leadership roles.

If your overall Retention Rate still looks stable but key talents or critical roles are showing signs of instability, TalentsAll can help review the issue from a market, data, and senior talent strategy perspective.

FAQ: Retention Rate, Regrettable Turnover Rate, and Executive Turnover Cost

What is Retention Rate?

Retention Rate is the percentage of employees a company retains during a specific period. It shows workforce stability, but it should be segmented by role type to reflect the real risk of losing key talents or senior executives.

Why can organization-wide Retention Rate be misleading?

Organization-wide Retention Rate can be misleading because it treats all employees equally. A strong overall Retention Rate does not necessarily mean the company is retaining key talents, senior executives, or critical role holders.

What is Regrettable Turnover Rate?

Regrettable Turnover Rate is the turnover rate of employees the company does not want to lose, such as high performers, key talents, succession candidates, and critical role holders. It should be monitored together with Retention Rate.

What does the cost of replacing a senior executive include?

The cost of replacing a senior executive may include executive search fee, assessment cost, interview cost, temporary coverage cost, vacancy period, onboarding cost, learning curve, operational disruption, and the risk of follow-on resignations.

Why are counter-offers not always effective for improving Retention Rate?

Counter-offers may work temporarily if compensation is the main reason for leaving. However, if the root cause is lack of authority, unclear career path, burnout, cultural misalignment, or loss of trust, a salary increase may only delay the resignation and create internal equity issues.

How can companies improve Retention Rate among key talents?

Companies can improve Retention Rate among key talents by combining Total Rewards, Career Path, and Talent Risk Management. The key is to identify early warning signs, understand what key talents value, and intervene before they decide to leave.
