In-House vs Outsourced SDR Cost Calculator (United Kingdom)
What an SDR really costs in the UK once you add national insurance, pension, tools, recruitment, ramp time, and management. Then compare it to an outsourced program, month by month.
Want UK pipeline without the headcount?
We run outbound for B2B software companies growing in the UK with native senior SDRs. No recruitment, no ramp, no management load. You get meetings, not a hiring project.
What this calculator does
This tool shows the true cost of an in-house SDR in the UK and compares it to an outsourced sales program over 18 months. Most companies put an SDR's salary next to an agency's monthly fee and call it a comparison. It is not. Salary leaves out national insurance, pension, tools, recruitment, management, and the ramp period where you pay full cost for partial output.
UK on-costs are lower than most of Europe, so the raw cost gap is smaller than in France or the Nordics. That makes the UK decision less about money and more about speed and focus. This calculator shows you exactly where the line sits at your numbers.
What an SDR really costs in the UK
From April 2025, employer national insurance rose to 15% and the threshold dropped to £5,000. Add pension auto-enrolment at 3% of qualifying earnings and you are paying close to 18% on top of salary before tools and management.
Why the salary-vs-fee comparison is misleading
1. On-costs are lower here, but they are not zero
The UK is one of the cheaper European markets to employ in, but 18% in NI and pension still turns a £50,000 package into £59,000 before a single tool. An agency fee already has the equivalent built in.
2. You still pay full cost during the ramp
A new SDR takes three to five months to reach full productivity. The salary, the NI, and the tools run at 100% the whole time. The output does not. An outsourced team with the process and tools already built starts producing in four to eight weeks.
3. One SDR is not a sales function
To match an agency you also need someone to manage the rep, build the lists, and keep the messaging sharp. The agency fee covers all of it. A single hire covers none of it.
4. The UK is easy to exit, which cuts both ways
UK labour law is flexible. Statutory notice is one week per year of service, and contracts are often one month. That makes a bad hire cheaper to unwind than in France or Germany, but it also means an in-house rep can leave with little notice and take the pipeline knowledge with them.
When in-house still makes sense
In the UK the cost gap is smaller, so the focus argument carries more weight. A dedicated in-house SDR who knows your product deeply, full-time, can be the right call for your home market. Outsourcing tends to win when you want speed, when you are testing a new segment, or when you would rather buy pipeline than run a hiring and management project.
Frequently asked questions
Why is the employer cost only 18%?
The UK does not have the heavy social charges France or the Nordics carry. Employer NI at 15% plus 3% pension is the bulk of it. That is real, but it is far below the 40%-plus you see on the continent.
Should I enter the cost in pounds?
Yes. This tool runs in GBP because that is what you pay a UK hire and a UK-focused agency. Enter the salary and retainer you would actually face.
What outsourced monthly cost should I use?
Enter the retainer you would pay per equivalent unit. A senior SDR program targeting the UK typically runs £3,000 to £4,500 per month. Use a real quote if you have one.
Does outsourced really start faster?
When the agency knows your kind of sale, yes. The tools, process, and market knowledge are already there, so meetings can start in four to eight weeks against three to five months for a fresh hire.
Where do these numbers come from?
Salary ranges come from UK market data. NI and pension rates come from current HMRC and auto-enrolment rules. The cost structure and ramp timelines come from the Profitbl whitepaper and from running these campaigns for clients.
