When does each rep cohort pay back fully-loaded cost, and how do bookings compound over their tenure?

№ 159 · Rep ROAS curve

01

Definition

MetricCumulative gross profit from a rep cohort divided by cumulative fully loaded cost of that cohort, plotted by month of tenure

Unitratio of cumulative gross profit to cumulative fully loaded rep cost, by tenure month

Cumulative rep bookings divided by fully-loaded rep cost, plotted across months since hire. Multiple cohort lines for hire cohorts or segments. Reveals when reps become profitable. Build per-rep cohort. Example: Top quartile crosses 1.0x at M6, hits 4.8x at M24; bottom never crosses.

ROAS
Return on ad spend. Revenue attributed to a campaign divided by the spend on that campaign.

B2B SaaS $5M to $100M ARR, AE cohorts. Fully loaded cost taken as roughly 1.3x to 1.4x OTE including burden, tooling and allocated management. Gross profit taken as booked new ARR times subscription gross margin, counted once rather than as a recurring stream. · This is a sales-capacity curve and shares only its shape with the marketing ROAS curve in other sections. The denominator is a fully loaded headcount cost that continues whether or not the rep books anything, not media spend that can be switched off, which makes the early months of this curve structurally worse than a paid channel curve and the later months structurally better. Inputs are sourced but the curve itself is constructed: Bridge Group 2026 gives quota, OTE and 6.2 month ramp, Benchmarkit gives 81% subscription gross margin, RepVue gives realised attainment. Two cautions apply. Average AE tenure of 2.2 to 2.8 years means the right-hand end of the curve describes a minority of hires. And billing terms shift the whole curve left or right by months rather than weeks, with Tunguz modelling AE-only breakeven at roughly three months on annual prepay.

Category split omitted: Rep-level cohort returns are not published by segment by any two independent Tier 1 or Tier 2 sources; the curve is assembled from separately segmented quota, attainment, compensation and margin datasets.

When it looks bad

The cohort curve flattens below 1.0x and the average tenure marker arrives before the crossover point, so the cohort is exited or attrites before it has repaid what was spent on it.

Cohort sits at 0.9x at month 24 with 40% of the original hires already gone, meaning the cohort will never cross 1.0x.

What to do about it

  • Move to annual prepay before touching anything inside the sales org. Tunguz models AE-only breakeven dropping to roughly three months on annual prepay against materially longer on monthly billing, which moves this curve more than any performance intervention available.
  • Attack attrition rather than only ramp. Bridge Group reports SDR attrition at a 40% median with a 21% to 57% interquartile range, and AE turnover around 30%, so a curve that crosses at month 15 against a two-year average tenure leaves very little productive window even when it works.
  • Cut ramp months directly. At 6.2 months average and rising, ramp is the flat section at the start of this curve, and each month removed shifts the entire curve left by a month.
  • Plot cohorts separately by hire date and never blend them. A blended curve mixes cohorts hired under different quota, territory and pricing conditions and will show a smooth line that describes no actual group of hires.
