In-house takes 8 to 12 weeks to a first meeting, and 4 to 9 months to consistent qualified meetings. An agency reaches first qualified meetings in 14 to 30 days because the infrastructure, copy frameworks and list-building are already solved. “Domains have to be bought and warmed.” A new hire does all of that from zero, usually while also learning your product. A team that runs this every month starts at step four. If you need pipeline inside the next quarter, ramp time is usually the deciding factor rather than cost.
Total cost, year one “Expect roughly $6,500 to $8,500 per month fully loaded for one in-house SDR, against £3K-£12K per month for a done-for-you retainer.” Using 2026 market data from RepVue and RevPilots, a B2B SDR in a developed market sits at $55,000 to $62,000 base, with on-target earnings around $83,000 to $85,000. Add tools at $500 to $1,500 per month for data, sequencing and inbox infrastructure. Add 3 to 5 hours of management per week from someone senior enough to fix broken copy.
Total cost, year one “The in-house figure is not the salary line. It is the salary plus everything attached to it.” Using 2026 market data from RepVue and RevPilots, a B2B SDR in a developed market sits at $55,000 to $62,000 base, with on-target earnings around $83,000 to $85,000.

Expect roughly $6,500 to $8,500 per month fully loaded for one in-house SDR, against £3K-£12K per month for a done-for-you retainer. The in-house figure is not the salary line. It is the salary plus everything attached to it. “Add tools at $500 to $1,500 per month for data, sequencing and inbox infrastructure.” That is the honest comparison. An agency retainer replaces the salary, the tools and the management hours with one invoice. See our outsourced SDR service for how that is structured.

The decision comes down to three things. How fast you need pipeline. How much fixed cost you can carry while nothing happens. And who absorbs the risk if the first version of the messaging does not land. “Outbound is also a volume game, which changes the maths.” Total cost, year one
The decision comes down to three things. How fast you need pipeline. How much fixed cost you can carry while nothing happens. And who absorbs the risk if the first version of the messaging does not land. “Across our own campaigns the average was 202 leads contacted per opportunity, and a single in-house SDR rarely gets a list that size in their first quarter.” Total cost, year one
Both models work, and they win in different situations. Most comparisons online are written by agencies, so they end the same way. This one gives you the numbers behind each choice and lets you do the arithmetic yourself. “The decision comes down to three things. How fast you need pipeline. How much fixed cost you can carry while nothing happens. And who absorbs the risk if the first version of the messaging does not land.” Outbound is also a volume game, which changes the maths. Across our own campaigns the average was 202 leads contacted per opportunity, and a single in-house SDR rarely gets a list that size in their first quarter. One hire is not one engine. It is one seat inside an engine that still needs to be built around them.
