Quick Answer: Offshore call center attrition usually runs between about 20% and 35% a year, but the figure depends heavily on the country, the type of work and how attrition is measured. The best current survey data puts South African contact centres at 25% agent attrition, against 21% in the UK and 30% in the US, according to ContactBabel’s 2025-26 South African contact centre research. Philippine and Polish BPO surveys sit in a similar band, while reliable published figures for Mexico, Colombia and Egypt do not exist.
Key Takeaways
- South Africa: 25% agent attrition, with 75% of operations losing under 10% of agents in the first 90 days (ContactBabel, 2025).
- UK: 25.76% employee attrition on 2025 data, down from a post-pandemic peak of 33.2% in 2022 (CCMA Benchmark, 2026).
- Philippines: 31% voluntary attrition in 2022, down from 36% in 2021, with the industry expecting 25% to 30% for 2023 (CCAP survey via Philstar).
- Poland: 22.5% voluntary turnover in BPO centres in 2023, the highest of any centre type (ABSL, 2024).
- Replacing one average-performing agent costs about $20,800, or 30% to 50% of a new agent’s salary (SQM Group).
- Many attrition figures quoted online come from outsourcing vendors’ own marketing. The table below uses only associations, analysts and surveys that publish their method.
Offshore Call Center Attrition Rates by Country
The most reliable published attrition rates for contact centre and BPO agents range from 21% to 31% a year across the markets with recent survey data. South Africa sits at 25%, below the US (30%) and the Philippines (31%), and in line with the UK. Several popular offshore destinations publish no comparable figure at all.
| Country | Annual attrition | Year covered | Publisher | What it measures |
|---|---|---|---|---|
| South Africa | 25% | 2025-26 study | ContactBabel | Agent attrition, survey of 106 SA contact centres (BPO and in-house) |
| United Kingdom | 21% | 2025-26 study | ContactBabel | Agent attrition, UK benchmark in the same study |
| United Kingdom | 25.76% | 2025 | CCMA Benchmark | Employee attrition, excludes internal moves |
| United States | 30% | 2025-26 study | ContactBabel | Agent attrition, US benchmark in the same study |
| Philippines | 31% (voluntary) | 2022 | CCAP / Willis Towers Watson via Philstar | Survey of 145 CCAP member organisations |
| Philippines | 25% to 30% (expected) | 2023 | CCAP via Philstar | Industry expectation from first-half data |
| Poland | 22.5% (voluntary) | 2023 | ABSL / Mercer | Median voluntary turnover, BPO centres only |
| India | 17.4% | 2024 | Deloitte via Economic Times | All industries, not BPO-specific |
| Mexico, Colombia, Egypt | No published figure | 2023 to 2026 | None found | Only vendor estimates exist |
Two cautions apply when you read this table. First, the years differ, so compare the direction of travel rather than treating every row as a 2025 snapshot. Second, voluntary and total attrition are different numbers: the Philippine and Polish rows count resignations only, so total exits, including dismissals, run higher. The next section explains why this matters more than the headline percentage.
What Is a Normal Attrition Rate for Offshore BPO Teams?
A normal attrition rate for an offshore BPO team is roughly 20% to 30% a year for established inbound customer service work. Rates above 35% usually signal a problem with pay, scheduling or management. Rates below 15% are possible on stable, well-paid accounts, but they are uncommon in high-volume voice work.
That range is consistent across the strongest sources. ContactBabel’s figures for South Africa (25%), the UK (21%) and the US (30%) all fall inside it, and the UK’s CCMA Benchmark settled at 25.76% in 2025 after peaking at 33.2% in 2022, when the pandemic and the “Great Resignation” drove a spike (CCMA). In the Philippines, the industry’s own trade body reported that 60% to 70% of agents used to leave their companies each year until around 2016, before the rate began to fall (Philstar).
Size matters too. ContactBabel’s US research found that median agent attrition in large centres of 200 or more seats was more than twice that of centres under 50 seats, and that new-hire attrition is “demonstrably influenced by starting salaries” (ContactBabel US, 2021). That is older data, but the pattern explains why a small dedicated team inside a well-run provider can retain agents better than a very large shared floor. To judge any provider’s number, you first need to know how it was calculated.
How Attrition Is Calculated, and Why Numbers Disagree
Attrition is the number of employees who leave during a period divided by the average headcount over that period, multiplied by 100. Call Centre Helper sets out the standard formula (Call Centre Helper):
Attrition rate = leavers in the period ÷ average headcount in the period × 100
Most disagreements between published figures come from four choices made before the sum is done:
- Voluntary or total. Some surveys count only resignations. Others add dismissals and redundancies.
- Internal moves. The CCMA reports internal attrition separately. In 2022 it was 26.9% on top of 33.2% employee attrition (CCMA).
- Period. A six-month rate is not an annual rate. The Philippines’ 19% figure for the first half of 2023 is a half-year number and cannot be compared with annual rows.
- Population. India’s 17.4% covers all industries. NASSCOM’s 14.6% for March 2026 covers its tracked technology companies (NASSCOM). Neither is a contact centre agent rate.
When a provider quotes you a low attrition figure, ask for the formula, the population and the period in writing. Once the definitions line up, the conversation moves to what attrition actually costs.
The Cost of Agent Attrition
Each agent who leaves costs far more than a recruitment fee. SQM Group’s benchmarking puts the average cost of replacing an average-performing contact centre agent at $20,800, covering hiring, training, lost productivity and the impact on customers (SQM Group).
SQM expresses this as 30% to 50% of a new agent’s salary. Its worked example uses a $52,000 salary, where a $20,800 replacement cost equals 40%. The same research notes that it takes six months or more on average for a new agent to perform at the level of the person they replaced, and that the first 90 days are when most agents quit.
You can estimate your own exposure with a simple calculation:
Annual attrition cost = team size × attrition rate × cost to replace one agent
For example, a 50-agent team at 30% attrition replaces 15 agents a year. At SQM’s $20,800 average, that is $312,000 a year. Treat this as your own model rather than an industry benchmark, and use your real salary and training costs. For the full picture of what drives outsourcing budgets beyond wages, see our guide to the true cost of offshore customer service.
Customers feel attrition before the finance team does. New agents resolve fewer issues first time and handle calls more slowly while they learn, which is why early-tenure attrition deserves its own measure.
Early Attrition: The First 90 Days
Early attrition is the share of new hires who leave within their first 90 days. It is the most expensive kind, because the business has paid to recruit and train someone who never reaches full productivity.
South Africa performs well here. ContactBabel found that 75% of South African contact centre operations lose fewer than 10% of their agents in the first 90 days (ContactBabel). No comparable national first-90-day figure is published for the Philippines, India or the UK, so ask every shortlisted provider for its own number.
Measure early attrition separately from annual attrition, using a hiring cohort:
| Measure | What to count | Divide by |
|---|---|---|
| 90-day new-hire attrition | Starters in a cohort who leave within 90 days | All starters in that cohort |
| Training attrition | Starters who leave before training ends | All starters entering training |
| Annual agent attrition | All agent leavers in the year | Average agent headcount in the year |
A provider that reports only annual attrition can hide a training-room problem. With the definitions settled, the next question is where offshore destinations differ and why.
Why Attrition Differs Between Offshore Destinations
Attrition differs between countries mainly because of how much competition there is for agents, how pay compares with local alternatives, and how much of the work runs on night shifts. Country averages also hide large differences between providers in the same city.
- Competition for talent. The Philippines has one of the largest voice BPO workforces in the world, and experienced agents can move between employers easily, which historically pushed attrition very high.
- Pay relative to the local market. El País reported in 2026 that an inexperienced Philippine agent earns around $291 a month (El País), so small pay rises elsewhere tempt people away.
- Shift patterns. Serving the US from Asia means permanent night shifts. South Africa’s UTC+2 time zone means UK and European work runs in normal daytime hours, and US East Coast mornings overlap with the South African afternoon.
- Career paths. Markets where a contact centre job leads somewhere, such as team leader, quality or workforce management roles, keep people longer.
We compare these trade-offs in more depth in our guide to South Africa vs the Philippines and in our South Africa vs UK and US contact centre benchmark. Knowing the drivers lets you ask providers the right questions.
How to Check a Provider’s Attrition Claims
Ask for attrition data on the specific account type you are buying, calculated with a stated formula, over at least 12 months. A single company-wide figure tells you little about the team that will answer your customers.
Request these from every shortlisted provider:
- Annual agent attrition for comparable accounts, voluntary and total shown separately.
- 90-day new-hire attrition by cohort for the last four hiring classes.
- Average agent tenure on accounts like yours.
- Tenure-banded quality scores, such as first-contact resolution for agents under and over six months.
- The retention levers they use: pay reviews, promotion paths, shift design, coaching ratios.
- Contract protections, such as backfill timelines and knowledge-transfer rules when an agent leaves.
If a provider cannot produce the cohort data, treat its headline number with caution. The same discipline applies to cost claims, which we cover in our guide to call center outsourcing cost.
Frequently Asked Questions
What is the average call center attrition rate? Recent survey data puts contact centre agent attrition at 21% in the UK, 25% in South Africa and 30% in the US (ContactBabel, 2025). The UK’s CCMA Benchmark reported 25.76% employee attrition on 2025 data. Most established offshore operations fall between 20% and 30% a year.
What is a normal attrition rate for offshore BPO teams? Roughly 20% to 30% a year is normal for established inbound customer service work. Rates above 35% usually point to problems with pay, scheduling or management. Rates under 15% are possible on stable, well-paid accounts but are uncommon in high-volume voice work.
What is the BPO attrition rate in the Philippines? The Contact Center Association of the Philippines reported voluntary attrition of 31% in 2022, down from 36% in 2021, based on a Willis Towers Watson survey of 145 member organisations. It expected 25% to 30% for 2023. Involuntary exits are counted separately.
What is the call centre attrition rate in South Africa? ContactBabel’s 2025-26 research found 25% agent attrition in South African contact centres, and 75% of operations lose fewer than 10% of agents in their first 90 days. That compares with 21% in the UK and 30% in the US in the same study.
How do you calculate call center attrition? Divide the number of employees who left during a period by the average headcount over that period, then multiply by 100. State whether you are counting voluntary leavers only or all leavers, and whether internal moves are included, or the figure cannot be compared.
How much does it cost to replace a call center agent? SQM Group puts the average cost of replacing an average-performing agent at $20,800, or 30% to 50% of a new agent’s salary. That covers hiring, training, lost productivity and customer impact. It often takes six months or more for a new agent to reach full performance.
Why is staff turnover so high in offshore centers? The main causes are strong competition for experienced agents, pay that is easy to beat locally, permanent night shifts for overseas time zones and limited career paths. Turnover is lower where agents work daytime hours, see a route to promotion and are coached regularly.
Which countries publish no reliable call center attrition data? We found no 2023 to 2026 attrition figure from an association, government body or reputable news source for Mexico, Colombia or Egypt. Figures circulating for those markets come from outsourcing vendors’ own marketing, so they should be checked before you rely on them.
