Designing a commission plan is really an exercise in behavioral design disguised as a compensation spreadsheet. Reps will optimize for whatever the plan actually rewards, not for what the company intended in the abstract — so the design process should start with a clear answer to one question: what behavior do we actually want to see more of?

Calculate Commission NowStep 1: Define the Actual Goal
Before choosing rates or tiers, be explicit about what the plan should drive — new customer acquisition, larger deal sizes, faster sales cycles, higher-margin sales, retention and renewal, or some combination. A plan designed without this clarity tends to default to 'reward total revenue,' which is rarely precisely what a business needs most.
Step 2: Choose a Structure That Matches the Goal
| Primary Goal | Structure That Fits |
|---|---|
| Push past initial quota | Tiered or accelerator-based commission |
| Protect margin | Commission calculated on net margin, not gross sale value |
| Encourage collaboration | Split commission for assisted or team-sold deals |
| Build recurring revenue | Separate, ongoing rates for renewal and expansion |
Trying to solve every goal with one structure usually produces the complexity problem covered in other articles in this series — better to prioritize the one or two goals that matter most this year and design cleanly around those.
Step 3: Set Rates Using Realistic Modeling, Not Guesswork
Model a handful of realistic scenarios — an average deal, a strong month, a weak month — through the proposed structure and check whether the resulting pay feels fair and motivating relative to the target on-target earnings (OTE) for the role.
OTE = Base Salary + Expected Commission at 100% Quota AttainmentExample: if a role's target OTE is $80,000 with a $50,000 base, the commission component needs to average roughly $30,000 at full quota attainment. If quota is $500,000 in annual sales, the required average rate is roughly $30,000 ÷ $500,000 = 6% — a number worth checking against the actual proposed rate structure before finalizing it.
Step 4: Keep the Formula Explainable in One Sentence
A good test during design: can the plan be explained to a new hire in a sentence or two, without a spreadsheet? "You earn 5% on everything up to quota, and 8% on everything above it" passes this test. A plan with five overlapping conditions and exceptions does not, regardless of how carefully it was modeled.
Pro Tip
If the plan document itself is longer than one page for a straightforward individual-contributor role, that's usually a sign it's trying to solve too many problems at once.
Step 5: Decide on Payout Timing and Clawback Rules Upfront
Define exactly when commission is paid (immediately on signing, on invoice, on payment received) and under what specific, limited conditions it can be clawed back (e.g., cancellation within 30 days, non-payment by the customer). Writing these rules down clearly before the plan launches prevents the trust erosion that comes from ambiguous after-the-fact decisions.
Step 6: Build in a Ramp Period for New Reps
A rep starting a new role typically needs time to build a pipeline before their commission reflects a fair measure of their effort. A structured ramp — often a temporary draw or reduced quota for the first one to three months — avoids unfairly penalizing a new hire for a slow start that's a natural part of any sales cycle.
Step 7: Review and Adjust on a Regular Cadence
A plan that made sense a year ago may no longer match current company priorities, average deal size, or market conditions. Reviewing the plan annually (or after a significant strategy shift) and communicating any changes clearly, with advance notice, keeps the plan aligned without surprising the team mid-period.
Worked Example: Designing a Plan From Scratch
Goal: encourage larger deal sizes without sacrificing margin. Chosen structure: tiered commission based on deal size, calculated on net margin rather than gross sale value, with a 5% base rate up to a $10,000 deal size and 7% on the portion above that. A $25,000 deal at a healthy margin: $10,000 × 0.05 = $500, plus $15,000 × 0.07 = $1,050, total $1,550 — directly rewarding the larger deal size relative to a smaller one, while the margin basis discourages excessive discounting to hit that size artificially.
Pro Tip
Before rolling out a new or revised plan company-wide, run last quarter's actual deal data through the proposed structure using a commission calculator to see what it would have paid — comparing that to what was actually paid under the old plan is the clearest gut-check on whether the new design achieves its intended goal.
Step 8: Pressure-Test the Plan Against Edge Cases
Before launch, deliberately think through unusual scenarios the plan will eventually encounter: a deal that spans two commission periods, a customer who upgrades mid-contract, a rep who's out on leave for part of a quarter, a deal sourced by one rep but closed by another after a territory reassignment. A plan that only works cleanly for the average, straightforward deal will generate a steady stream of manual exceptions and manager judgment calls once real-world complexity shows up — and every one of those exceptions is a small erosion of the plan's promised predictability. Listing out the five or six most likely edge cases and deciding how each is handled, in writing, before launch saves considerable friction later.
Step 9: Align Commission Plan Timing With Financial Reporting Cycles
Whenever possible, structure commission periods to align with the company's existing financial reporting cadence (monthly or quarterly close) rather than an arbitrary custom cycle. This isn't just an accounting convenience — it makes it far easier for finance and sales leadership to reconcile commission payouts against actual recognized revenue, and reduces the operational overhead of running commission calculations on a schedule that doesn't match anything else in the business. A plan that pays out on the 15th of each month while revenue closes on a calendar-month basis, for instance, creates an unnecessary translation step every single period.
Step 10: Communicate the Plan the Way You'd Want to Receive It
How a plan is communicated at rollout matters almost as much as its actual design. A plan introduced through a dense written document alone, with no live walkthrough or opportunity for questions, tends to generate more confusion and quiet resentment than the same plan introduced through a short session where reps can ask questions and see worked examples using realistic deal sizes from their own territory. Providing a simple calculator or spreadsheet reps can plug their own numbers into — rather than asking them to trust an abstract formula — meaningfully increases both understanding and buy-in from day one.
A Second Worked Example: Redesigning an Underperforming Plan
A company's existing plan pays a flat 5% commission on all sales, with no distinction between new and renewal business, and leadership has noticed renewal rates quietly declining as reps chase new logos almost exclusively. The redesigned plan: 6% on new business, 4% on renewals, plus a 2% expansion bonus on any account that grows its contract value at renewal. A rep who closes $30,000 in new business and renews an existing $50,000 account with a $10,000 expansion under the new plan earns: new business ($30,000 × 0.06 = $1,800) plus renewal ($50,000 × 0.04 = $2,000) plus expansion bonus ($10,000 × 0.02 = $200), totaling $4,000 — compared to $4,500 under the old flat 5% plan on the same $90,000 in total activity. The redesign intentionally pays slightly less overall in exchange for creating a much stronger incentive to prioritize renewal and expansion revenue going forward, which is exactly the behavior change leadership set out to encourage in Step 1.
Pro Tip
A redesigned plan doesn't need to preserve the exact same total payout as the old one to be considered successful — it needs to reward the behavior that actually matters to the business right now, even if that means some reps earn modestly less under the new structure for the same raw sales total than they would have under the old one.
Step 8: Plan for What Happens During a Territory or Role Change
Territory realignments, promotions, and role changes are inevitable in a growing sales organization, and a plan that doesn't address what happens to in-progress deals and commission during a transition creates exactly the kind of ambiguity that erodes trust. Decide upfront: does a rep keep commission on deals they sourced but didn't close before leaving a territory? Does a newly promoted rep's old-role commission structure apply to deals already in their pipeline, or does the new role's structure apply immediately? Writing these transition rules into the plan document before any specific transition actually happens removes the temptation to decide case-by-case under pressure.
Step 9: Decide How the Plan Handles Team-Sold Deals
For deals that involve genuine team selling — an account executive, a solutions engineer, and a customer success manager all contributing meaningfully to winning and onboarding a large account — decide in advance how commission credit is allocated rather than leaving it to informal negotiation after each deal closes. Some plans use a fixed split (e.g., 70% account executive, 20% solutions engineer, 10% customer success), while others use a manager-adjudicated model for unusually complex deals. A fixed, published split is more predictable and less prone to dispute, though many organizations pair it with a documented exception process for the rare deal that doesn't fit the standard pattern.
A Final Worked Example: Modeling Plan Cost Against Revenue Impact
Before finalizing any new plan, model its total expected cost against a realistic revenue forecast to confirm the commission expense ratio falls within a sustainable range for the business. If the proposed plan, modeled against last year's actual deal volume, would have paid out $340,000 in commission against $4,000,000 in revenue — an 8.5% commission expense ratio — compare that against your target ratio and your gross margin to confirm the business can sustainably support that level of variable compensation cost even in a strong sales year, not just in an average one.
Pro Tip
Run your proposed plan's total cost against at least two scenarios — a conservative revenue year and a strong one — before finalizing it, since a plan that looks affordable at average performance can become surprisingly expensive in a breakout year, which is a good problem to have but still needs to be budgeted for rather than discovered after the fact.
A Closing Principle: Plans Are Living Documents
Every principle covered in this guide — clarity of goal, matching structure to goal, realistic rate modeling, simplicity, clear payout and clawback rules, a ramp period for new hires, and regular review — points toward the same underlying idea: a commission plan works best when it's treated as a living document that evolves deliberately with the business, rather than a static artifact finalized once at launch and left untouched. The businesses that get the most sustained motivational value from their commission plans are rarely the ones that designed the single most clever structure on day one; they're the ones that built a habit of checking, listening to feedback, and adjusting deliberately over time, using exactly the kind of structured review process outlined in Step 7.
