"Split the credit 70/30" sounds like a clean compromise in the room. Then the finance director asks "so what does this actually cost?" and nobody has a quick answer — because split credit interacts with two commission rates, maybe three quota structures, and the company ends up paying 120% of normal commission on a deal nobody wants to audit.
This tool makes the arithmetic explicit. Enter the deal value, choose Split mode (one commission pool divided across reps — weights sum to 100%) or Overlay mode (each rep gets a full independent credit — weights can exceed 100%), add your participants with their commission rates, and see the per-rep payouts plus total company cost. The tool flags the common failure mode: splits that don't sum to 100% and overlays that balloon past 150% of deal value without anyone noticing.
Split mode vs Overlay mode — the critical distinction
Split mode (distributed credit)
One crediting pool equal to deal value, distributed across reps by weight. Weights must sum to 100%. Example: sourcing SDR gets 20% credit, closing AE gets 80%. On a $200K deal, SDR gets credit for $40K, AE for $160K. Total credit equals the deal value. Use this for handoff scenarios where multiple reps contributed to one deal and the plan wants to recognize that proportionally.
Overlay mode (independent credit)
Each participant receives their own independent crediting event against their own quota. Weights are per-person percentages of deal value and can sum to anywhere between 100% and 300%+ depending on design. Example: Primary AE gets 100% credit, Overlay SE gets 50% credit. Both quotas move. On a $200K deal the company records $200K + $100K = $300K of credit events. Use this for overlay/specialist roles where each person has a separate quota and the plan intentionally rewards both.
Commission rate matters too
The rate is applied to each person's credited amount, not to the deal value directly. If the SDR's rate is 3% and the AE's is 10%, that's a very different total cost than if both were at 8%. Always model the rate per person — "average" rates hide structural cost.
In Overlay mode, the tool computes the total commission burden as a % of deal value (e.g. an Overlay scenario with Primary AE at 10% and SE at 5% → total cost 15% of deal value). Above 15% is a red-flag for most software businesses — you're at margin danger. Above 20% and you're subsidizing sales effort with investor money. The tool surfaces this number so you can see it before approving the plan design.

ℹ️ How this tool works +
The question it answers: If I split credit (or stack overlays) between multiple reps on this deal, what will each rep earn — and what will the total commission cost the company?
What to enter:
- Deal Value ($) — the crediting base. Usually year-one TCV. Enter full dollars, e.g.
200000for $200K. - Mode: Split = one pool divided (weights sum to 100%). Overlay = independent credits (each weight is % of deal value; multiple reps can each get 100%).
- Rows (2–5 participants). For each: role label, weight %, commission rate %.
- Weight % in Split mode must sum to 100%. In Overlay mode it's the independent % of deal value each rep is credited with.
What you'll get back:
- Headline KPIs: Total commission cost, effective commission rate (cost ÷ deal value), and total credit recorded.
- A per-rep table showing credited amount and commission payout.
- A single-attribution comparison — what the same deal would cost under one primary rep at the highest rate (the "no split" baseline).
- Warnings if Split weights don't sum to 100% (data error) or if total Overlay commission cost exceeds 15% of deal value (margin red flag).
- A plain-English interpretation of whether the design is conservative, typical, aggressive, or margin-dangerous.

How to interpret the cost output
Effective rate ≤ 10% of deal value
Falcon's benchmarks: Conservative design. Works for high-margin SaaS, services with healthy GM%, and most enterprise plans. Sustainable across volume. If your split adds up to this range, no margin concerns.
Effective rate 10–15%
Typical SaaS range. Most healthy comp plans land here once you account for accelerators and overlay credit. Monitor closely when volume ramps — rates that work at 10 deals/quarter break at 100.
Effective rate 15–20%
Aggressive. Only justified when product margins are very high (80%+ software GM), deal sourcing costs are genuinely distributed across multiple roles, or you're paying a premium to attract talent in a specific segment. Review annually — this is not a stable long-term design for most businesses.
Effective rate above 20%
Margin-dangerous. You're either overlaying too many roles, paying commission rates too high, or both. In most businesses this means every sales dollar is costing you 20¢+ before you account for base salaries, benefits, overhead, and COGS. Investor-subsidized growth businesses can run here briefly; mature businesses cannot.
The following is a composite scenario based on patterns Falcon has observed across multiple engagements.
"Let's just double-credit everyone to keep everyone happy" produces Overlay-mode scenarios where 3 reps each get 100% credit on a deal, the plan pays 30% total commission, and nobody notices until the end-of-year cost review. Always calculate the total commission burden before committing to an overlay design — retroactively clawing back an overlay is the #2 cause of comp plan disputes, right behind territory changes.

If the participants are peers (e.g., two AEs who both touched the deal), usually Split. If one is a primary quota carrier and the others are overlay/specialist roles with separate quotas, usually Overlay. When in doubt: Split protects the margin; Overlay rewards the contribution.
Use the rep's base commission rate at the attainment level for the deal. If the deal pushes them into accelerator territory, model at the blended effective rate. Don't use "target" rates — use the rates that would actually be paid on this specific deal.
Not cleanly in this tool — run two separate scenarios and combine the outputs. In practice, complex deals with both split and overlay dimensions are almost always worth simplifying. Every additional layer of crediting logic is an additional source of disputes.
The cost the deal would have generated under the simplest possible structure: one primary rep, at the highest rate among the participants, with 100% credit. It's the "do nothing fancy" cost. Comparing the split/overlay cost to this baseline tells you what you're paying for complexity.
