Weighing whether to outsource your SDRs or build an in-house team? It’s a decision many businesses wrestle with, and the real costs aren’t always obvious.
On paper, hiring in-house can look like the cheaper option. Salaries are easy to calculate. The costs of recruiting, onboarding, managing, and replacing SDRs? Not so much.
Once you factor everything in, our model estimates that an in-house SDR costs approximately £104,000 a year in the UK and $160,000 in the US. That’s roughly £8,700 or $13,400 a month per rep, including the estimated cost of lost productivity during ramp-up.
In this article, we break down those costs using findings from The State of Sales Development 2026, alongside UK and US industry benchmarks. We’ll also explore how these figures compare with outsourcing, so you can make a more informed decision about which approach works best for your business.
What an In-House SDR Really Costs in 2026
Base salary accounts for less than 40% of the total estimated cost of an SDR. Here’s how the numbers break down for one SDR in the UK and the US.
| Cost category | UK (£) | US ($) |
|---|---|---|
| Base salary | 39,000 | 60,300 |
| Commission | 16,700 | 25,800 |
| Top-performer bonus | 5,600 | 8,600 |
| Pension and benefits | 10,400 | 15,300 |
| SDR management | 8,400 | 13,000 |
| Data and tech stack | 5,200 | 7,100 |
| Equipment and expenses | 1,000 | 2,000 |
| Recruitment fee | 8,000 | 12,400 |
| Replacement (turnover) | 4,400 | 7,100 |
| Ramp-up productivity loss | 5,300 | 8,600 |
| Total estimated annual cost | £ 104,000 | $ 160,200 |

Three areas are particularly easy to underestimate.
Compensation adds up quickly. Median base salaries in the report are £39,000 in the UK and $60,300 in North America. Once you include commission, benefits, and employer contributions, the actual cost is significantly higher.
Recruitment and turnover are expensive. Hiring doesn’t end when an offer is accepted. Recruiting fees, onboarding, and replacing departing SDRs all contribute to the cost of maintaining a productive team.
Ramp-up time affects your return on investment. New SDRs don’t reach full productivity overnight. During those first few months, businesses are investing in a resource that isn’t yet delivering its full potential.
The tech stack is another expense that can quickly grow.
According to the report, 89% of teams use LinkedIn Sales Navigator, 83% use a data provider, 78% use an AI tool, 76% use an email tool, 74% use a sales engagement platform, 71% use call recording, and 53% use a dialer.
When these tools are licensed per seat, the costs add up.
Our model assumes SDRs earn their full target commission. At the average quota attainment reported (approximately 82% in the UK and 79% in North America), actual variable compensation could be lower, depending on how commission plans are structured.
The Costs People Forget
Even a detailed cost model can miss some of the operational challenges associated with building an in-house SDR team.
People leave sooner than you might expect.
According to the report, SDRs have been in their roles for an average of 19.8 months (19.6 months in the UK and 18.7 months in North America).
For businesses building an in-house team, turnover creates costs that extend well beyond recruitment fees. Every departure can mean another hiring process, additional onboarding, and another period of reduced productivity.
John Norton, CRO at Intradiem, highlighted the management challenges facing smaller in-house teams during a recent memoryBlue and TechCXO webinar about “When to (and when not to) outsource your GTM”:
“With five people, I couldn’t really have an expert to lead that team. I couldn’t have someone ringing the bell every day and getting people motivated.”
He also explained how outsourcing can help protect against employee turnover:
“Three guys leaving doesn’t affect the output.”
New hires take months to become productive.
According to the report, in-house SDRs take approximately 2.5 months to reach full productivity.
That’s a significant investment before a new hire begins consistently contributing to pipeline targets. And when employees leave, the process starts again.
Vacancies and management time rarely appear in the original budget.
When an SDR position is vacant, pipeline targets don’t disappear.
And when the position is filled, someone still needs to coach the rep, review calls, manage performance, and refine the playbook.
Our model includes an allocation for SDR management, but it doesn’t account for every potential vacancy period or operational disruption. Depending on the business, these factors can increase the effective cost of maintaining a productive team.
None of this means building an in-house SDR team is a bad idea.
It simply means base salary alone isn’t the right number to compare against an outsourced SDR program.
What the 2026 Data Says About Outsourcing
Outsourcing offers businesses another way to access SDR capacity without taking on every operational responsibility associated with building a team internally.
According to The State of Sales Development 2026, only 11% of surveyed teams use outsourcing.
Those teams reported average SDR quota attainment of 84.5%, broadly in line with in-house teams.
The clearest difference was ramp-up time.
Outsourced SDRs reached full productivity in approximately 1.5 months, compared with 2.5 months for in-house SDRs.
That’s an important distinction.
Outsourcing doesn’t automatically guarantee better sales performance. But it can help businesses launch programs faster, reduce the operational burden of recruiting and managing SDRs, and adjust capacity as business needs change.
How Do the Costs Compare?
Based on our model, one in-house SDR costs approximately £8,700 or $13,400 per month when direct expenses, allocated costs, and estimated productivity losses are included.
Outsourced SDR programs can range from a few thousand dollars to approximately $12,000 per month, depending on the provider, scope, languages, and level of support.
These aren’t necessarily like-for-like comparisons. Pricing models, service levels, and the number of resources included can vary significantly between providers.
However, the figures demonstrate why businesses should compare the total cost of maintaining productive SDR capacity, rather than simply comparing an outsourced fee with an employee’s salary.
With outsourcing, many of the responsibilities associated with recruitment, training, management, and employee turnover shift to the provider.
That can make costs more predictable while allowing internal teams to focus on strategy and revenue generation.
Of course, price isn’t the only consideration.
During the webinar “When to (and when not to) outsource your GTM”, another panelist shared a lesson from working with a low-cost SDR agency:
“The question that I didn’t ask was, how many people do you have managing, leading and developing these SDRs? If I had known, it would have been like a 25-to-1 ratio.”
It’s a useful reminder that not all outsourcing partners operate the same way.
Before comparing fees, ask how SDRs are recruited, trained, managed, and measured.
How to Choose Between In-House and Outsourced SDRs
There’s no universal answer.
The right approach depends on your lead volume, growth plans, geographic coverage, and internal management capabilities.
If it’s an inbound motion, start with your lead volume.
As an illustrative planning assumption, one SDR might work approximately 300 marketing-qualified leads per month, or 15 per day across 20 working days.
Actual capacity will depend on lead quality, qualification requirements, outreach channels, and the level of personalization required.
If your inbound volume is relatively low or inconsistent, a dedicated in-house SDR may not be the most efficient use of resources.
Outsourcing can provide flexibility without requiring you to build an entire team.
Consider your territories and languages.
Expanding into new markets often requires more than simply hiring another SDR.
Different regions may require local language capabilities, market knowledge, and territory-specific outreach strategies.
Building that coverage internally can mean hiring multiple people, each with their own recruitment, management, and technology costs.
An outsourcing partner with existing international capabilities can help businesses test and expand into new markets without making the same upfront investment.
Be realistic about management capabilities.
The report found that enablement and clear career progression were associated with better outcomes.
The takeaway? Simply hiring SDRs isn’t enough.
They need coaching, development, clear expectations, and a structured environment in which they can succeed.
If your business doesn’t have the resources to provide that support internally, outsourcing may offer a more practical route.
Don’t overlook the hybrid approach.
For many businesses, the choice isn’t strictly in-house or outsourced.
A hybrid model can offer the best of both.
You might retain a small internal SDR team focused on strategic accounts while using an outsourced partner to support new markets, manage additional volume, or test new go-to-market strategies.
Whitney Myers, CEO of Zuar, described this approach during a memoryBlue webinar:
“I want to outsource the experiment. I want to run a pilot, see what works, swap it out… I start with external, pull that in-house, and then go external again whenever I need the power of scale.”
It’s an approach that allows businesses to experiment, learn, and scale without committing to permanent headcount before a strategy has been validated.
Regardless of which model you choose, ownership of your go-to-market strategy should remain with your business.
As we explain in our article When to (and When Not to) Outsource Your GTM:
- “Outsourcing execution does not mean outsourcing ownership.”
- “Outsourcing execution is valuable. Outsourcing brand ownership is risky.”
- “The key is to treat outsourcing as a way to learn quickly, not simply as a way to reduce costs.”
The Bottom Line
Outsourcing SDRs isn’t automatically cheaper, and building an in-house team isn’t automatically better.
The real question is which model delivers the capacity, expertise, flexibility, and results your business needs at a sustainable cost.
When comparing your options, look beyond salaries and monthly service fees. Factor in recruitment, management, technology, turnover, ramp-up time, and the operational resources required to keep your SDR team productive.
The numbers may surprise you.

Notes and Sources
Methodology
Salary, compensation mix, manager span of control, tenure, ramp-up time, technology adoption, quota attainment, and outsourcing figures come from The State of Sales Development 2026 (SDR Leaders Global, 574 sales development leaders surveyed, published October 14, 2026).
Modeling assumptions
The report doesn’t provide every expense required to calculate the total cost of an SDR.
Our model uses the report’s 70/30 base-to-variable compensation split to estimate commission and includes a hypothetical top-performer bonus equal to 10% of on-target earnings.
Benefits are modeled using employer contributions and estimated health care costs, while recruitment and turnover costs are based on industry benchmarks.
Ramp-up costs assume 50% productivity for 2.2 months. These represent an estimated productivity loss rather than an additional cash expense.
Equipment, technology, and other operating expenses are estimates.
The model is illustrative, and actual costs will vary based on compensation structures, recruitment methods, employee tenure, technology contracts, and organizational structure.
