How to read the output
The calculator estimates three numbers over a 24-month horizon:
- Partner-sourced ARR: revenue attributable to your partner program.
- Total program cost: partner commissions/margin + program operating cost (your time, MDF, tooling).
- Net contribution: gross margin on partner-sourced ARR minus total program cost.
If net contribution is positive by month 18, the program is paying for itself. If negative, the program is investment-mode and needs continued executive air cover. Both are valid; the question is whether you have the runway and the trajectory.
Assumptions baked in
The calculator uses standard SaaS partner assumptions:
- First partner-sourced close at month 4 (referral) or month 9 (reseller).
- Ramp curve: 1 → 2 → 4 → 6 → 8 closes per quarter over the first two years.
- Gross retention 85%, expansion factor 1.15x.
- Commission paid one-time on first-year ACV; renewal commission at 50% in year 2.
- Program operating cost scales with active partner count.
These can be overridden in the full xlsx version. For most companies the defaults are within 20% of actual outcomes.
What the model does not capture
The calculator estimates revenue and direct program cost. It does not model: indirect benefits (brand lift, customer retention from partner-delivered services), opportunity cost (would the same time invested in direct sales produce more?), or the option value of having a channel in markets you may want to enter later.
For most programs, indirect benefits are material but unpredictable. Use the calculator to assess the direct ROI question; use judgment for the strategic value.
Common patterns by motion
- Referral programs typically break even at month 6-9 if recruitment is well-targeted. Direct-cost ROI is high; absolute revenue is modest.
- Reseller programs typically break even at month 15-20. Higher absolute revenue but longer investment period.
- Technology partnerships rarely produce direct revenue but show 15-25% retention lift among customers with 2+ active integrations.
- SI programs break even at month 18-24 and produce sustained revenue and retention lift thereafter.
Using the full calculator
The full Partner Unit Economics Calculator in the Foundations Pack lets you model: per-partner economics, tier-mix sensitivity, multi-year ramp curves, expansion treatment, renewal commission scenarios, MDF investment vs return, and the impact of activation rate on total program economics. It is the document finance teams ask for at month 9 when they want to understand whether the program is funding itself.
