In-house SDR vs outbound agency: the 2027 cost comparison

TL;DR

• One in-house SDR in the US costs about $146,418 in year one once you add benefits, recruiting, tools and a share of a manager to the $80,000 median on-target pay. The salary cost alone is $106,262.

• In the UK the salary cost is about £45,083 a year, and in Germany about €56,563, before recruiting, tools and management.

• A new SDR takes about 3 months to ramp and stays about 1.9 years on average, per the Bridge Group. That puts the real US cost at about $16,269 per productive month in year one.

• To compare an agency quote, convert both sides to cost per meeting held. At Bridge Group's median quota, one US SDR costs about $1,627 per meeting held in year one.

The in-house SDR vs outbound agency decision comes down to two numbers: what one SDR really costs once you add everything around the salary, and what the same pipeline would cost from an agency. This guide builds the first number from published salary, tax, hiring and tool data for the US, UK and Germany, and gives you a break-even formula and a list of questions to turn any agency quote into a like-for-like comparison. It also covers when in-house wins, when an agency wins and when a hybrid makes sense. To run the numbers for your own team, try our SDR cost calculator.

What goes into the cost of an in-house SDR

The salary is the visible part. A fully loaded SDR cost has seven lines:

1. Base salary, paid from day one.

2. Variable pay, commission or bonus at target.

3. Employer costs: payroll taxes, social insurance, pensions and benefits.

4. Recruiting: job ads, recruiter fees and interview time.

5. Tools: data, sequencing, dialler, CRM and LinkedIn seats.

6. Management: a share of a manager's time and salary.

7. Ramp and turnover: the months before a new SDR is productive, repeated each time one leaves.

The first six are cash. The seventh is time, and it is the one most cost comparisons leave out.

SDR salary and on-target earnings in 2026

United States. The Bridge Group's 2025 SDR Metrics Report, based on 351 B2B companies, puts median SDR on-target earnings at $80,000, unchanged since 2022, with a 68:32 split between a $55,000 base and $25,000 variable. Self-reported data varies: PayScale shows an average base of $51,677 from 840 profiles, while Glassdoor shows average total pay of $104,273. This guide uses the Bridge Group figures because they come from companies, not individual submissions.

United Kingdom. Glassdoor UK shows an average base of £30,000 and average additional pay of £9,000, with average total pay of £39,778. PayScale UK puts the average base at £29,462. This guide uses £30,000 base and £9,000 variable.

Germany. PayScale Germany shows an average base of €36,631, with commission between €10,000 and €15,000. The sample is small (39 profiles), so treat it as a floor. This guide uses €36,631 base and the low end of the commission range, €10,000.

For how to structure the variable part, see our guide to SDR comp plans.

Employer costs by country

Employer costs are where the three markets differ most.

• United States. There is no single statutory rate, so the best benchmark is the Bureau of Labor Statistics. Its Employer Costs for Employee Compensation release for June 2026 shows private-industry sales and related workers earning $26.99 an hour in wages and salaries and receiving $8.86 in benefits, including $2.69 in legally required benefits. Benefits add 32.8% on top of pay. Applied to the full $80,000 of on-target earnings, including variable pay, that is $26,262; applying the BLS rate to variable pay is our assumption.

• United Kingdom. Employers pay 15% National Insurance on earnings above £5,000 a year in 2026 to 2027, per GOV.UK rates and thresholds, and at least 3% pension contributions on earnings between £6,240 and £50,270, per GOV.UK's workplace pensions guide. On £39,000 that is £5,100 of NI and £983 of pension, £6,083 in total. The £10,500 Employment Allowance can reduce NI for smaller employers, but it applies to the company, not to each hire.

• Germany. Employers pay roughly half of each statutory social insurance contribution. On the 2026 rates listed by Haufe, the employer share is 9.3% pension, 1.3% unemployment, 7.3% health plus half of the 2.9% average additional health contribution, 1.8% long-term care and 0.15% insolvency levy: about 21.3%, or €9,932 on €46,631. Accident insurance and the U1 and U2 levies come on top and vary by employer. The 2026 contribution ceilings, €69,750 a year for health and €101,400 for pension per the German federal government, sit well above SDR pay, so the full rate applies.

Recruiting, tools and management

Recruiting. SHRM's 2025 benchmarking reports, based on 2,371 members, put the average cost per non-executive hire at $5,475. That covers the hiring process, not the months it takes. We found no comparable official benchmark for the UK or Germany, so add your own figure there, including any recruiter fee.

Tools. A basic outbound stack for one SDR, at list prices, costs about $4,380 a year:

• LinkedIn Sales Navigator Core: $959.88 a year.

• Kaspr Starter for contact data: $49 per user per month on its pricing page, $588 a year.

• Pipedrive Growth CRM: $39 per seat per month billed annually, $468 a year.

• Aircall Professional for calling: $50 per licence per month, per its pricing page. Professional is the plan with the Power Dialer (the $30 Essentials plan has none), and every plan needs at least 3 licences, so a single SDR pays $1,800 a year. Two more SDRs can share those licences at no extra cost.

• Instantly Growth for email sequencing: $47 a month on monthly billing, $564 a year.

Your stack may cost more. Larger data plans, AI research tools and conversation intelligence can multiply this line. Our guide to the best AI SDR tools covers the newer options. Sending infrastructure (domains and inboxes) comes on top.

Management. SDRs need a manager who coaches, reviews calls and keeps the pipeline honest. The same Bridge Group report puts SDR manager on-target earnings at $146,000 and the average team at 6.4 SDRs per leader, down from 8 in 2021 to 2023. The ratio rises with company size, from 3.6 below $5 million in revenue to 8.1 at $500 million and above. With the same 32.8% benefits loading (our assumption for a manager's pay), each SDR carries $146,000 x 1.3283 / 6.4 = about $30,301 of management cost a year. If a founder manages a first SDR, the cost is founder time instead. We found no published UK or German SDR manager pay benchmark, so add your own there.

Ramp, tenure and attrition: the hidden cost

The Bridge Group's tenure and ramp data shows an average ramp of 3.0 months, the lowest since 2010, and an average tenure of 1.9 years. It also reports 40% median annual attrition in 2024, of which 16 points were promotions, and only 60% of SDRs at quota, the lowest in the study's history.

What that means for cost:

• Year one has about 9 productive months. You pay for 12 months and get roughly 9 at full output.

• The ramp repeats. At 1.9 years of tenure, about 3 of every 23 months go to ramp. When an SDR leaves or is promoted, you pay recruiting again and wait another 3 months.

• Quota is not a guarantee. If 40% of SDRs miss quota, plan pipeline on attainment, not on quota.

Figure: the year-one cost of one US SDR by cost line, from Bridge Group, BLS, SHRM and vendor pricing. GROU calculation.

Put together, one US SDR costs $146,418 in year one: $80,000 on-target pay, $26,262 in benefits, $30,301 of management, $5,475 to recruit and $4,380 in tools (each line rounded to the dollar). Spread over 9 productive months, that is about $16,269 per productive month.

What an outbound agency costs, and what to ask for in a quote

Outbound agencies price in different ways: monthly retainers, pay per meeting, setup fees, or a mix. We do not quote market price ranges here because we could not find an independent, published dataset for them, and an agency's prices are best compared on your own brief. Our guide to outbound agency pricing models explains how each model works.

What you can do is make every quote comparable. Ask each agency for:

• The full monthly fee and the setup fee, and whether data, tools, domains and inboxes are included or billed separately.

• Contract length and notice period, and what happens to the domains, inboxes, lists and sequences if you leave.

• The meeting definition: who counts as a qualified attendee, what happens with no-shows, and whether meetings are held or only booked.

• Expected volume after ramp and how long the ramp takes. Ask for the range they plan to, not the best case.

• Channels: email only, or email, LinkedIn and phone.

• Who does the work, how many clients each person handles, and how often you review results.

• Reporting: access to the raw activity and reply data, not only a monthly summary.

Our guide on how to brief a lead generation agency covers the brief side, and the first 90 days with an outbound agency covers what to expect after you sign.

The break-even formula

Convert both options to the same unit. Cost per meeting held is the fairest, because it captures ramp and productivity, not just price.

In-house cost per meeting = year-one cost / (meetings per month x productive months)

Break-even agency fee per month = in-house cost per meeting x meetings per month the agency commits to

For one US SDR at the Bridge Group's median quota of 10 meetings held a month, over 9 productive months:

• Flat monthly cost: $146,418 / 12 = about $12,202 a month.

• Cost per meeting held: $146,418 / 90 = about $1,627.

• Cost per converted opportunity, at the median quota of 6 a month: $146,418 / 54 = about $2,711.

Figure: break-even values for an agency quote against one US SDR in year one, at Bridge Group median quotas. GROU calculation.

If an agency commits to 12 qualified meetings a month from month two, the break-even fee is about 12 x $1,627 = $19,524 a month. If it commits to 6, it is about $9,762. These are at full quota. Since only 60% of SDRs hit quota, the real in-house cost per meeting is usually higher, which raises the break-even.

Quality matters as much as volume. A meeting with the wrong person costs more than no meeting, because it takes AE time. Compare conversion from meeting to opportunity, not only meeting counts. To size how many meetings you need in the first place, see our guide to setting a 2027 pipeline target with coverage maths.

When in-house wins, when an agency wins, and hybrid

Figure: a decision guide for in-house SDRs, an outbound agency or a hybrid model.

In-house wins when:

• Outbound already works and you have a repeatable playbook to hand over.

• You have a manager with time to hire, coach and review calls.

• The product is complex and conversations need deep product knowledge.

• You want an SDR-to-AE path to grow your own sales team.

• Volume is steady enough to keep a full-time person busy for years.

An agency wins when:

• Outbound is new or unproven and you need to find out what works before you hire.

• You need pipeline sooner than a hire could ramp. Hiring plus a 3-month ramp means months without full output.

• No one has time to hire, coach and manage SDRs.

• You are testing a new market, segment or language.

• Volume changes and you want to scale up or down without hiring and letting go.

Hybrid works when: the agency builds and runs the system (data, sending infrastructure, sequences and testing) and your team handles replies, calls and meetings. It is also a path in its own right: start with an agency, prove the motion, then bring it in-house once you know which messages and segments work. If your question is when to start at all, see when to start outbound.

Other ways to lower the in-house cost

• Hire in a lower-cost market. Nearshore SDRs are another option.

• Cut the ramp. Documented playbooks, call libraries and pre-built sequences help new SDRs get productive sooner. The Bridge Group suggests the drop to 3.0 months may reflect AI-powered onboarding and tighter expectations.

• Keep SDRs longer. Each extra month of tenure spreads recruiting and ramp over more productive time. A clear promotion path helps.

• Right-size the stack. Five tools at $4,380 a year is a basic stack. Check seats every quarter.

FAQ

How much does an in-house SDR cost per year?

In the US, about $106,262 in salary and benefits at the Bridge Group's $80,000 median on-target pay, and about $146,418 in year one once you add recruiting, tools and a share of a manager. In the UK the salary cost is about £45,083 and in Germany about €56,563, before recruiting, tools and management.

What is the average SDR salary in 2026?

The Bridge Group's 2025 report puts the US median at $55,000 base and $80,000 on-target earnings. In the UK, Glassdoor shows an average base of £30,000 and total pay of £39,778. In Germany, PayScale shows an average base of €36,631.

How long does it take an SDR to ramp?

About 3.0 months on average, per the Bridge Group, the lowest since 2010. Average SDR tenure is 1.9 years.

Is an outbound agency cheaper than hiring an SDR?

It depends on the quote and the results. Convert both to cost per meeting held. One US SDR at median quota costs about $1,627 per meeting held in year one, so an agency that delivers the same quality of meetings for less is cheaper in year one.

What should I ask an outbound agency before signing?

Ask for the full fee including setup and tools, contract length and notice period, the meeting definition and no-show rules, expected volume after ramp, the channels used, who does the work and how many clients they handle, and access to raw activity data.

Can you combine an agency with in-house SDRs?

Yes. A common hybrid has the agency run data, infrastructure and sequences while in-house reps handle replies and calls. Some teams also use an agency to prove outbound before hiring.

Bottom line

One in-house SDR costs far more than the salary: about $146,418 in year one in the US once benefits, recruiting, tools and management are added, and about $16,269 per productive month after a 3-month ramp. UK and German salary costs are lower, but the same extra lines apply. Hire in-house when outbound is proven and someone can manage it. Use an agency when you need pipeline faster than a hire can ramp or the motion is still unproven. Either way, compare cost per meeting held, not monthly fees.
