I've reviewed commission plans from over 200 companies in the last two years. About 40% of them have the wrong structure for their sales motion. Not wrong because the math doesn't work on paper. Wrong because the structure incentivizes behavior that conflicts with the company's actual growth strategy.

A flat commission rate tells reps every dollar is equal. A tiered structure tells them dollars above quota are worth more. A draw tells them the company will backstop their earnings while they ramp. Each sends a different signal, and reps read that signal faster than you'd expect.

This guide breaks down every major commission model with real numbers, explains when each one fits, and covers the implementation details that separate plans that work from plans that generate resentment.

Data context: Commission ranges and benchmarks come from 1,500+ executive sales job postings tracked by The CRO Report, supplemented with published data from Pavilion, RepVue, and Betts Recruiting.

Flat Rate Commission: Simplicity as Strategy

Flat rate commission pays the same percentage on every dollar of revenue, regardless of quota attainment. Sell $500K, earn 10%. Sell $1.2M, earn 10%. The math is dead simple, and that's the point.

How it works in practice

Take an AE with $200K OTE split 50/50. Their $100K variable divided by a $1M quota gives a 10% commission rate. They earn $10K per $100K in closed revenue, whether that's their first deal or their twentieth. No tiers, no accelerators, no mental math.

Here's a concrete example:

Annual Bookings Commission Rate Commission Earned Total Comp (w/ $100K base)
$400K (40% attainment) 10% $40,000 $140,000
$800K (80% attainment) 10% $80,000 $180,000
$1M (100% attainment) 10% $100,000 $200,000
$1.5M (150% attainment) 10% $150,000 $250,000

When flat rate works

Flat rate fits three scenarios well. First, high-volume transactional sales where deal sizes are consistent ($10K-$30K ACV) and reps close 40-80 deals per year. The simplicity eliminates admin overhead and lets reps focus on volume. Second, early-stage startups that don't have enough data to set meaningful quotas. If you can't confidently set a quota, a flat rate at least ensures reps get paid fairly for what they close. Third, channel and partner sales where you want predictable margins on every deal.

When flat rate fails

It fails badly when you need outsized performance from your top reps. At 10% flat, the rep who closes $2M earns exactly double the rep who closes $1M. That sounds fair until you realize the $2M rep could earn 30-50% more at a competitor with tiered commissions and accelerators. Flat rate is a tax on your best people, and they know it.

I've watched three companies switch from flat to tiered structures and all three saw their top-quartile reps increase output by 18-25% within two quarters. The reps weren't working harder. They were finally being compensated proportionally to their impact.

Tiered Commission: The Industry Standard

Tiered commission pays increasing rates as reps hit higher levels of attainment. The first tier covers 0-100% of quota at a base rate. The second tier kicks in above quota at a higher rate. Some plans add a third or fourth tier for extreme overperformance.

Standard tier design

The most common structure across mid-market and enterprise SaaS:

Attainment Range Commission Rate Multiplier Rationale
0-100% of quota 10% 1.0x Base rate to hit OTE at plan
100-120% of quota 15% 1.5x Rewards above-plan performance
120-150% of quota 20% 2.0x Drives aggressive overperformance
150%+ of quota 25-30% 2.5-3.0x Retains top performers

With a $1M quota and 10% base rate, here's what the payout curve looks like:

  • $1M closed (100%): $100K commission, $200K total comp
  • $1.2M closed (120%): $100K + $30K (20% at 1.5x) = $130K commission, $230K total
  • $1.5M closed (150%): $100K + $30K + $60K (30% at 2x) = $190K commission, $290K total
  • $2M closed (200%): $100K + $30K + $60K + $125K (50% at 2.5x) = $315K commission, $415K total

That $2M rep earns $415K total comp compared to $300K under a flat structure. The $115K difference is what keeps them from answering recruiter emails.

Threshold vs. incremental tiers

This distinction trips up a lot of finance teams. In a threshold model, hitting 100% changes the rate on all dollars retroactively. In an incremental model, the higher rate only applies to dollars above the threshold. Incremental is standard and far more common because threshold models create massive payout jumps at tier boundaries.

Example of threshold risk: a rep at 99% attainment earns $99K commission. At 101%, they'd earn $151.5K under a threshold model (the full $1.01M at 15%). That $52.5K jump for $10K in incremental revenue is a budget problem. Incremental models avoid this entirely.

When tiered works

Tiered structures fit mid-market and enterprise sales where individual rep performance varies significantly (top reps close 2-3x what average reps close), where you have confident quotas based on historical data, and where retaining top performers is worth paying premium commission rates. Roughly 65% of B2B SaaS companies above $10M ARR use some form of tiered commission.

When tiered fails

If your quotas are set poorly, tiers amplify the problem. A rep who gets sandbagged with an unreachable quota never sees the accelerated tiers and feels cheated. A rep who gets a soft territory hits accelerators by June and coasts the second half. Tiered plans demand fair quotas. If you can't deliver that, stick with flat rate until your data improves.

Draw Against Commission: The Ramp Safety Net

A draw is an advance on future commissions. The company pays the rep a guaranteed amount during a defined period, and earned commissions offset the draw balance. There are two types, and the distinction matters.

Recoverable draw

The rep owes back any unearned draw. If the company pays $8K/month as a draw and the rep earns $5K in commissions, the rep carries a $3K deficit. That deficit accumulates and gets repaid from future earnings. Some companies cap the deficit. Others let it run indefinitely.

Recoverable draws are common in insurance, financial services, and real estate where commission-only compensation is standard but companies want to reduce early attrition. The practical challenge: if a rep builds a $30K deficit in their first 6 months, the repayment obligation makes months 7-12 feel like indentured servitude. You'll lose the rep before they pay it back.

Non-recoverable draw

The company absorbs any difference between the draw amount and earned commissions. This is the standard approach for SaaS ramp periods. A new AE gets 3-6 months of non-recoverable draw equal to 75-100% of their on-target variable, giving them financial stability while building pipeline.

Typical SaaS ramp draw structure:

  • Month 1-3: 100% of monthly on-target variable (full draw, no quota)
  • Month 4: 75% draw, 33% quota
  • Month 5: 50% draw, 67% quota
  • Month 6: 25% draw, 100% quota
  • Month 7+: no draw, full quota

The declining draw mirrors the increasing quota, ensuring total comp stays relatively stable through ramp. A $200K OTE AE on this structure earns roughly $16K-$17K/month total comp whether they're in month 2 (all draw) or month 8 (all commission). That stability matters for retaining new hires through the inevitable trough of their first two quarters.

When draws work

Draws fit companies with long sales cycles (6+ months to close), high-value enterprise deals where new reps need time to build pipeline, and any role where the first few months produce little to no revenue by design. They're also useful when you're hiring reps from competitors and need to bridge the gap between their old employer's commission checks and your pipeline ramp.

When draws backfire

Recoverable draws in SaaS are almost always a mistake. They attract risk-averse candidates (not who you want in sales) and create a negative-balance dynamic that poisons the rep-company relationship. If you don't believe a new hire will earn their commissions within 6 months, you have a hiring problem, not a comp problem.

Residual Commission: The Account Farming Model

Residual commission pays reps an ongoing percentage of revenue from their accounts, typically on renewal or recurring billing. The rep closed the deal in Year 1 and earns 2-5% of the annual contract value each subsequent year as long as the customer stays.

Where residual works

Insurance, financial services, managed services, and any business where the customer relationship spans years and the original salesperson maintains meaningful influence on retention. In these models, a senior rep might earn 40-60% of their total comp from residuals, creating a book of business that compounds over time.

Here's a concrete example from managed IT services:

Year New Business Commission Residual Commission (3%) Total Commission
Year 1 $80,000 (8% on $1M new) $0 $80,000
Year 2 $80,000 (8% on $1M new) $29,100 (3% on $970K retained) $109,100
Year 3 $80,000 (8% on $1M new) $56,730 (3% on $1.89M retained) $136,730
Year 5 $80,000 (8% on $1M new) $106,000 (3% on $3.5M retained) $186,000

The compounding is the feature. A rep who stays 5+ years builds a residual stream that makes them very hard to poach. That's retention by design, not by hope.

Where residual fails

High-growth SaaS companies that need reps focused exclusively on new business. Residual income turns hunters into farmers. Once a rep's residual stream covers their mortgage, the urgency to close new deals drops dramatically. If your growth plan requires 40%+ new logo acquisition year over year, residual commissions will slow you down.

The other risk is territory changes. If you reassign accounts, the rep loses their residual stream. If you don't reassign accounts, you can't optimize territories. Either way, someone's unhappy.

Hybrid Models: Combining Structures

Most mature sales organizations use hybrid structures that combine elements from multiple models. The most common hybrids:

Tiered + draw

Tiered commissions for the ongoing plan with a non-recoverable draw during ramp. This is the default for enterprise SaaS. New hires get financial stability during months 1-6, then transition to a tiered plan that rewards top performance. About 55% of enterprise SaaS companies above $50M ARR use this combination.

Flat + SPIF

A flat base rate for all revenue with short-term SPIFs for specific products, competitive displacements, or quarter-end pushes. This works for SMB sales teams where you want consistent behavior punctuated by targeted bursts. The flat rate keeps things simple. The SPIFs create urgency around strategic priorities.

Tiered + residual

Tiered rates on new business with a small residual on renewals. This is common in managed services and professional services where the selling rep maintains the client relationship. The tiered structure on new business keeps them hunting while the residual rewards retention. Typical split: 70% of variable from new business tiers, 30% from residual.

Commission Rate Calculation: The Math Behind the Plan

Setting the right commission rate starts with working backward from OTE. Here's the formula and the adjustments by segment:

Base commission rate = Variable comp / Annual quota

Adjustments by segment:

  • SMB ($10K-$30K ACV): 10-15% base rate. Higher rates because deal sizes are small and reps need volume to hit OTE. A $160K OTE rep with 60/40 split has $64K variable and a $500K quota, yielding a 12.8% rate.
  • Mid-market ($30K-$100K ACV): 8-12% base rate. Standard SaaS territory. A $200K OTE rep at 50/50 with $1M quota gets a 10% rate.
  • Enterprise ($100K-$500K ACV): 5-8% base rate. Larger deals reduce the rate needed to hit target. A $300K OTE rep at 60/40 with $1.5M quota gets an 8% rate.
  • Strategic ($500K+ ACV): 3-6% base rate. A $400K OTE rep at 60/40 with $2.5M quota gets a 6.4% rate. Fewer deals, higher stakes.

Implementation: Rolling Out a New Commission Structure

The structure itself is only half the job. How you implement it determines whether reps buy in or start updating their LinkedIn profiles.

Step 1: Model every rep individually

Before announcing anything, model each rep's projected earnings under the new structure using their trailing 12-month performance. If more than 20% of your team would earn less under the new plan, you either need transition guarantees or a different structure. Plans that reduce average earnings are cost-cutting disguised as comp redesign, and reps see through it immediately.

Step 2: Announce 30+ days before the fiscal year

Give reps time to process. Comp changes affect their financial planning, their mortgage qualifications, their family budgets. Dropping a new plan on January 2nd and asking for signatures by January 5th signals that you don't respect their lives outside the office.

Step 3: Provide a payout calculator

Build a simple spreadsheet or tool where reps can input different scenarios and see their payouts. If they can't model their own earnings, the plan is too complex. Every rep should be able to calculate their commission on any deal within 30 seconds.

Step 4: Run a parallel period

For the first quarter, show reps what they would have earned under both the old and new plans. If the new plan consistently pays less, you'll know before the complaints start. If it pays more for top performers and about the same for average performers, you've designed it correctly.

Step 5: Commit to no mid-year changes

Put it in writing. "This plan will not be modified until [next fiscal year]." That single sentence builds more trust than any all-hands presentation about "investing in our people."

Choosing the Right Structure for Your Sales Motion

The decision tree isn't complicated. It's driven by three variables: sales cycle length, deal size variability, and how much you need top-performer overperformance.

Sales Motion Recommended Structure Key Consideration
High-volume SMB (30-60 day cycles) Flat rate or simple 2-tier Simplicity drives volume
Mid-market SaaS (60-120 day cycles) 3-tier with accelerators Rewards overperformance, retains top reps
Enterprise SaaS (6-12 month cycles) Tiered + non-recoverable draw Draw covers ramp, tiers reward closers
Managed services / long-term contracts Tiered new biz + residual Residual rewards retention, tiers reward hunting
Early-stage startup (pre-PMF) Flat rate, no quota Don't set quotas you can't model
Channel / partner sales Flat rate by partner tier Predictable margins, simple partner economics

Common Mistakes in Commission Structure Design

Mistake 1: Too many tiers

I've seen plans with 6 tiers. Nobody remembers what tier they're in. If your rep can't tell you their current commission rate without looking at a spreadsheet, you've overcomplicated it. Three tiers is the sweet spot. Four is acceptable. Five or more is bureaucracy.

Mistake 2: Caps on accelerators

Capping commissions at 150% or 200% attainment teaches reps to sandbag. Once they see the ceiling coming, deals get pushed to next quarter. Uncapped plans cost more in the short term but generate 15-20% more revenue from top performers within two quarters.

Mistake 3: Identical structures across segments

Your SMB team and your enterprise team shouldn't have the same commission structure. Different sales cycles, different deal sizes, different win rates, different ramp times. One size fits nobody.

Mistake 4: Changing structures mid-year

Mid-year changes that reduce potential earnings are the number one reason sales reps start interviewing. Full stop. If the plan is broken, add a SPIF or a kicker. Don't restructure until the next fiscal year.

Mistake 5: Ignoring the spreadsheet test

Before finalizing any structure, hand the plan document to your newest AE and ask them to calculate their commission on a hypothetical $75K deal. If they can't do it in under a minute, simplify.
