Variable Compensation: Types, Structures, and Best Practices
Variable compensation is the performance-based portion of pay beyond base salary. Learn the types, how to set pay mix, and what makes variable comp actually drive results.
Variable compensation is the performance-based portion of pay paid on top of base salary. For sales roles, it's typically commission. For non-sales roles, it's usually a bonus tied to company or individual performance targets.
The defining feature: it's not guaranteed. Variable comp is earned by hitting a number — quota attained, revenue generated, deals closed, metrics hit. Miss the target and you earn less. Exceed it and you earn more.
For most sales teams, variable compensation is the largest single lever for driving rep behavior. How it's structured determines whether reps focus on new logos or renewals, large deals or volume, short-cycle transactions or long-term accounts.
Types of variable compensation
Variable pay takes several forms depending on role, industry, and comp plan design.
Commission is the most common form in sales. A rep closes revenue and earns a percentage of that revenue as variable pay. Commission can be flat (the same rate on all deals), tiered (higher rates above certain thresholds), or split across multiple metrics.
Target bonus is a fixed amount paid when a defined target is hit — often used for non-quota-carrying roles or roles where output isn't directly tied to closed revenue. An SDR manager might earn a bonus when their team hits a meetings-booked number. A customer success manager might earn one at renewal rate thresholds.
Profit sharing distributes a portion of company profits to employees, typically on an annual basis. More common in manufacturing and services than in SaaS, where gross margins vary widely by customer.
SPIFF (Sales Performance Incentive Fund) is a short-term incentive — a cash payment or gift for selling a specific product, closing deals before a deadline, or hitting a sprint metric. SPIFFs are additive to base plan commission, not a replacement.
Equity — stock options or RSUs — functions as long-term variable compensation in many tech companies. It vests over time and only pays out if company value grows. Not the same as short-term performance pay, but still variable in the sense that it's not guaranteed.
Most sales comp plans combine commission (the primary variable element) with occasional SPIFFs and annual bonuses. Understanding which type you're working with matters — they have different mechanics, tax implications, and motivational effects.
Variable compensation in sales
In sales, variable compensation is almost always tied directly to revenue. The standard structure is:
On-target variable (OTV) — the amount of variable pay a rep earns at 100% quota attainment. It's the variable half of OTE (on-target earnings). A rep with $160K OTE and a 50/50 pay mix has an OTV of $80K.
Commission rate — derived by dividing OTV by quota. If a rep's OTV is $80K and their quota is $800K, their commission rate is 10% on all closed ARR. This is the number reps track deal by deal.
Accelerators — higher commission rates above quota. Most plans don't stop paying at OTE. A rep who closes 125% of quota earns more than $80K in variable because a higher rate applies to the revenue above threshold. This is how OTE becomes a floor for top performers, not a ceiling.
According to Bridge Group's 2024 SaaS AE Metrics Report, median AE OTE is $190K with a 53:47 base-to-variable split. That means the typical AE's variable is roughly $89K at 100% quota — a meaningful portion of total comp that depends entirely on performance.
Pay mix: how much should be variable?
Pay mix — the ratio of base to variable — determines how much of a rep's compensation is at risk. It varies by role based on how much direct control they have over revenue outcomes.
| Role | Typical base/variable split | Why |
|---|---|---|
| SDR / BDR | 64/36 | Books meetings, doesn't close — less direct revenue control |
| SMB AE | 50/50 | Full-cycle ownership of smaller deals |
| Mid-Market AE | 55/45 | Longer cycles, more team involvement |
| Enterprise AE | 60/40 | 9–12 month cycles, less predictable close timing |
| Account Manager | 70/30 | Renewals and expansion, not new logo |

Higher variable ratios create stronger performance incentives but also more income volatility. A rep who misses quota for two consecutive quarters on a 50/50 plan has earned significantly less than their OTE both times — which either motivates a turnaround or accelerates attrition.
Two things to consider when choosing pay mix:
Sales cycle length. If a rep spends six months on a deal, they need enough base to cover living costs during that time. Enterprise reps on pure commission would earn nothing for half a year on a single deal. This is why enterprise roles carry more base.
Control over outcome. SDRs set meetings but don't control whether the AE closes. Paying SDRs 50% variable on commission creates misalignment — their income depends on a close they don't control. Bonus-based variable tied to meetings booked is a better fit.
Designing variable compensation that works
Variable comp has one job: align rep behavior with company revenue goals. The plans that fail usually do so because they incentivize the wrong thing, pay too late, or are too complex to calculate without a spreadsheet open.
Start with what you want reps to do. New logo acquisition? Expansion revenue? Renewals? Product mix? Every variable plan implicitly prioritizes certain behaviors. A flat commission rate on all products creates no incentive to push higher-margin SKUs. A renewal bonus paid quarterly creates a different behavior than one paid annually.
Keep the formula traceable. A rep should be able to calculate their own commission to within a few dollars after closing a deal. If they can't, you have a trust problem waiting to happen. Shadow accounting — reps tracking their own commissions in parallel spreadsheets — is the first sign a plan is too complex.
Pay frequently enough to feel real. Monthly variable pay reinforces deal-by-deal behavior. Annual bonuses create recency bias — the last three months matter more than the first nine. For most sales roles, monthly or quarterly variable pays out close enough to the behavior to feel motivating.
Model three attainment scenarios. Before launching a plan, calculate total comp payout at 70%, 100%, and 130% of quota. Make sure 70% attainment is livable, 100% is competitive with market OTE, and 130% is achievable without breaking your cost-of-sales budget.
Set a quota-to-OTE ratio that makes sense. The median quota-to-OTE ratio in B2B SaaS is 4.2x, according to Bridge Group's 2024 data. At 5x OTE, a $160K OTE implies an $800K quota. The commission payout at quota ($80K) divided by quota revenue ($800K) is 10%. That number has to fit within the company's gross margin and CAC targets.
When variable compensation drives performance — and when it doesn't
Variable pay works well when:
- Reps have clear control over the outcome (close rates, deal velocity, product mix)
- The metric is easy to verify and calculate without ambiguity
- Payment is close enough in time to the behavior it rewards
- Attainment rates are calibrated so 60–70% of reps hit quota in a typical period
It stops working when:
- Quota attainment drops too low. If only 35% of reps hit quota regularly, variable comp isn't motivating the bottom half — it's just tracking who's performing and who isn't. At that point, the plan has a quota-setting problem, not a variable comp problem.
- The formula is too complex to self-calculate. Reps who can't verify their commission start keeping shadow spreadsheets. Shadow accounting is expensive to reconcile and signals that the comp process has broken trust.
- Metrics are gamed instead of achieved. Pure call-volume SPIFFs generate calls, not pipeline. Commission paid on booking date rather than cash collected creates pressure to pull forward deals that don't close cleanly.
According to Bridge Group's 2024 data, only 51% of SaaS AEs hit quota — down from 66% in 2022. That shift suggests many teams have a quota calibration problem: variable comp is structurally there, but the attainment bar is set too high for the incentive to function as intended.
Variable compensation and commission tracking
The operational side of variable compensation is where most mid-market teams run into trouble. The plan looks simple on paper: close a deal, earn commission. In practice, it involves deal-level data from the CRM, adjustments for returns and clawbacks, split credit across multiple reps, product mix calculations, tier thresholds, and pay dates that may not align with close dates.
A 20-rep team with three plan types — SMB, mid-market, and expansion — can easily have 150+ individual commission calculations per pay period. Done manually in spreadsheets, that's several hours of sales ops time and a meaningful error rate.
Tools like Carvd automate commission calculations from CRM data, so reps get real-time visibility into their variable earnings — no waiting until the end of the month to find out what a deal was worth.
