The Two Numbers: 57.3 Percent Overall, 41.2 Percent in Software
dialfyne.com's SDR statistics, citing RepVue's 2025 dataset, put overall B2B SDR quota attainment at 57.3 percent and software specifically at 41.2 percent, the lowest of any segment measured. The gap between the two numbers is the important part: software isn't just below average, it's the weakest-performing category in the dataset, which makes it a meaningfully different starting assumption than "most reps hit their number."
Why Software Ends Up the Worst-Performing Segment
Two sourced, corroborated trends point at plausible causes. Since February 2024, Gmail and Yahoo have enforced SPF, DKIM, and DMARC authentication and spam-complaint thresholds on bulk senders, per Proofpoint's coverage, which has made cold email meaningfully harder to land reliably. And dialfyne.com's data, citing 6sense, puts the number of dial attempts needed to reach a contact at roughly 21, up from 17 the prior year. A software SDR working the two most common outbound channels is working in a harder environment than the benchmark that set expectations a few years ago.
What Sub-50-Percent Attainment Costs, Once You Connect the Numbers
Fully loaded SDR cost runs $98,000 to $173,000 a year, per the industry-estimate range attributed to Bridge Group. If 41.2 percent is the realistic attainment rate in software specifically, a meaningful share of that spend is very likely going toward output below the number a hiring plan originally budgeted for. This is a reasoned inference from two sourced figures, not a separately measured statistic, but it's the connection a realistic hiring plan has to make rather than assuming the fully loaded cost buys full-quota output by default.
The Quota-Attainment Trap in Hiring Plans
A common mistake is budgeting pipeline as though a new SDR will produce at 100 percent of assigned quota once ramped. If the segment median is 41.2 percent, that assumption is off by more than half before a single call or message goes out. A more realistic plan budgets pipeline against something closer to the segment median, with attainment above that treated as upside rather than the baseline expectation.
A Cost-Per-Result Comparison Instead of a Cost-Per-Rep One
Directive Consulting's 2024 data, via The Starr Conspiracy's 2025 benchmark page, puts median cost-per-SQL at $762 and median cost-per-MQL at $198 across B2B SaaS. Held against a $350 to $600 pay-per-meeting rate for a held, double-confirmed demo, the per-meeting model prices a specific, delivered result rather than a rep's theoretical capacity, which sidesteps the quota-attainment question entirely: you're not exposed to any single rep's attainment curve, because you only pay for meetings that were actually held.
How to Use This Number in Your Own Planning
Before budgeting a new SDR hire's expected output, ask what attainment assumption the plan is built on. If it's closer to 100 percent than to the 41.2 percent segment median, revisit the pipeline math with the lower, more realistic figure. And when comparing that adjusted output against a pay-per-meeting rate, remember the per-meeting model only bills for what was actually delivered, which removes the attainment-rate guesswork from the comparison altogether.
What this means for you
- Software SDR quota attainment sits at 41.2 percent, the lowest of any segment measured, versus 57.3 percent overall, per RepVue 2025 data cited via dialfyne.com.
- A harder outbound environment, more dial attempts per contact and stricter email authentication rules since 2024, is a plausible, sourced factor behind the low attainment rate.
- A pay-per-meeting rate prices a delivered result, not a rep's theoretical capacity, which sidesteps the quota-attainment risk that a headcount hire carries.
