Calculating commissions is the operational heart of every sales compensation program. The math itself is rarely the hard part, multiply the relevant base by the relevant rate. The hard part is choosing the right method for the role, the deal type, and the behavior the company wants to drive. This guide walks through eight sales commission methods, the formula behind each, and a worked example you can adapt. For broader context on how commission fits into total pay, see the pillar guides on On Target Earnings and incentive compensation.
The Basic Sales Commission Formula
Every commission method reduces to the same underlying formula:
Commission = Sale Amount × Commission Rate
The variables change depending on the method. Sale amount might be revenue, annual contract value, gross profit, or units sold. Commission rate might be flat, tiered, ramped, or accelerated. But the structure of the calculation does not change. Once the method is chosen, calculating the commission is a single multiplication, repeated for each deal and rolled up across the period.
What separates the seven methods below is not the formula. It is what the company is paying for, and how aggressively it wants to motivate the rep above target.
8 Sales Commission Methods
The table below summarizes the eight most common commission methods used in B2B sales today, followed by a worked example for each.
| Method | How It Works | Best For | Example |
|---|---|---|---|
| Flat-Rate (Straight) | Single percentage on every closed deal | Simple, transactional sales | 10% on every deal |
| Tiered | Rate increases at attainment thresholds | Mature reps in stable territories | 8% to 100%, 12% above |
| Ramped (Accelerator) | Base rate then accelerated rate above quota | Stretch-goal motivation | 10% to quota, 18% above |
| Revenue-Based | Percentage of bookings or ACV | Most B2B SaaS sales | 11.5% of ACV |
| Gross Margin | Percentage of profit, not revenue | High-discount or low-margin sales | 20% of gross profit |
| Base + Bonus | Flat dollar per close on top of small commission | Hybrid SDR / AE plans | $500 per close + 5% |
| Residual / Recurring | Pays on renewals and expansions, not just new | SaaS account managers | 15% on new + 5% on renewal |
| Consumption-Based | Percentage of consumed ARR or expansion | Consumption-priced SaaS | 7% of consumed ARR |
1. Flat-Rate (Straight) Commission
The simplest method. The rep earns a fixed percentage on every closed deal, regardless of size, attainment, or product mix. A flat-rate plan paying 10 percent commission on every deal would pay $5,000 on a $50,000 deal and $50,000 on a $500,000 deal. Easy to administer, easy for reps to understand, but offers no extra incentive to push past quota.
2. Tiered Commission
The commission rate increases at defined attainment thresholds. A common structure pays 8 percent up to quota and 12 percent above. A rep with a $1 million quota who closes $1.4 million would earn $80,000 on the first million (8% × $1M) plus $48,000 on the next $400,000 (12% × $400K), for $128,000 in total commission. Tiered structures are common in stable territories where reps reliably reach quota.
3. Ramped Commission with Accelerators
A base rate applies up to quota, and an accelerated rate kicks in above. Different from tiered in that accelerators can be much steeper, often 1.5x to 2x the base rate. Per WorldatWork, most enterprise sales plans include this kind of accelerator structure. A rep paid 10 percent to quota and 20 percent above would earn $100,000 on a $1M quota, then an additional $40,000 on $200,000 of overperformance, $140,000 total.
4. Revenue-Based Commission
The most common SaaS structure. Commission is calculated as a percentage of bookings or annual contract value. The median SaaS AE commission rate sits at roughly 11.5 percent of bookings at quota, per Bridge Group’s 2024 benchmark, with the broader range running between 11 and 14 percent. A rep with a quota of $870,000 paying 11.5 percent on bookings would earn $100,000 in variable pay at 100 percent attainment, typical for a $200,000 OTE at a 50/50 mix. RepVue’s 2025–2026 salary database reports SaaS account executive medians consistent with this structure.
5. Gross Margin (Profit) Commission
Commission is calculated as a percentage of gross profit, not revenue. This method aligns the rep with profitability rather than top-line growth, making it well-suited to environments with significant discounting authority or variable cost structures. A 20 percent commission on $50,000 of gross margin produces $10,000, independent of whether the deal closed at full price or after a 30 percent discount.
6. Base + Bonus Commission
A flat dollar amount is paid per qualifying close, often on top of a small base commission rate. Common in SDR-to-AE handoff structures and in hybrid plans where the company wants to reward both volume and revenue. A plan paying $500 per close plus 5 percent of ACV would pay $2,000 on a base for four closes and an additional $5,000 on $100,000 of ACV, $7,000 in total commission for the period.
7. Residual or Recurring Commission
Pays on renewals and expansions in addition to new business. Designed for SaaS account managers and customer success roles where retention drives the bulk of revenue value. A plan paying 15 percent on new bookings and 5 percent on renewals would pay $15,000 on a $100,000 new logo and $5,000 on every $100,000 renewal. The residual structure rewards long-term account relationships, not just initial close.
8. Consumption-Based Commission
Commission is paid on consumed ARR, usage growth, or expansion bookings rather than initial contract value. Pay mix typically runs 50/50 with longer-tail payouts. The math works backward from a target rep contribution: a rep responsible for $1.5 million of consumed ARR growth at a 7 percent rate would produce $105,000 in variable. Used in consumption-priced SaaS where the same customer can grow significantly over time, and where attributing growth between sales and customer success is intentional. Common in infrastructure platforms, AI APIs, and analytics tools that price on usage rather than seats.
How to Choose the Right Commission Method
The right commission method depends on four questions. First, what is the company actually paying for, top-line revenue, profitability, customer retention, or volume? Second, what behavior should the plan amplify, closing more deals, closing larger deals, protecting margin, or driving renewals? Third, how much administrative complexity can the operations team support? Per Talentfoot’s 2026 Sales Compensation Study, most plans cluster around a 50/50 base-to-variable split, which leaves meaningful room for the variable structure to do real work. Multi-year deals warrant a fourth question: should commission pay on TCV (total contract value across all years) or on year-1 ACV (annualized contract value)? Paying on TCV pulls forward commission and rewards multi-year deal mechanics; paying on ACV preserves cash flow and aligns commission with each year’s revenue. Most companies in 2026 use a blended structure: a portion of TCV at signing for incentive purposes, with the remainder paid as recurring commission as each renewal anniversary passes.
Most B2B SaaS organizations end up using a hybrid: revenue-based commission as the core, with ramped accelerators above quota and a tiered structure underneath for early-attainment reps. The right compensation plan design matches the method to the strategy, then keeps both flexible enough to evolve as the business changes.
Sales Commission Calculator: What You Need
A working commission calculator takes four inputs: the sale amount (revenue, ACV, units, or gross profit, depending on method), the commission rate or rate curve, the rep’s attainment percentage, and any applicable accelerators or thresholds. The output is the commission earned on the sale and the cumulative commission earned across the period. For a closely-related role-by-role walk-through, see the OTE salary calculation guide.
Sales Commission FAQs
What is the average sales commission rate?
Bridge Group’s 2024 SaaS AE Compensation Report places the median commission rate at 11.5 percent of bookings at full attainment, with most B2B SaaS plans falling between 8 and 14 percent.
How do I calculate commission on a tiered plan?
Calculate each tier separately, then sum. For an 8% / 12% structure with quota at $1M and total bookings of $1.4M: 8% × $1M = $80K, plus 12% × $400K = $48K, for $128K total commission.
What is the difference between revenue and gross margin commission?
Revenue commission pays on top-line bookings; margin commission pays on gross profit. Margin-based plans align reps with profitability and discourage excessive discounting, but require accurate cost data to administer.
Are commissions paid before or after attainment is verified?
Most plans pay commission shortly after the deal is booked, with clawback or true-up provisions if revenue is later adjusted. Some plans hold a portion until full payment is received from the customer.
Are commissions clawed back if customers churn?
Increasingly, yes. Clawback provisions have become more common in 2024-2026 as churn pressure has grown. A typical clawback recovers commission if a customer churns within 6 to 12 months of signing, prorated by remaining contract term. Reps should understand the specific clawback window and conditions in their plan before counting commission as fully earned.
Calculating commissions correctly is operationally essential, but choosing the right method is strategic. The companies that get the most leverage from compensation match the commission structure to the behavior they want, evolve it as the business changes, and keep the math transparent enough that reps can predict their own pay. At Optymyze, compensation management provides the engineering layer that makes complex commission models, tiered, ramped, residual, hybrid, hold together at scale, with full audit trails and the flexibility to change without rebuilding from scratch.
