Tiered Commission Structure: How to Build One That Scales

A flat commission rate is easy to explain and easy to calculate. It's also easy for your top rep to stop caring in October once they've already hit a number that justifies coasting.

A tiered commission structure solves that. By paying higher rates above quota, it keeps high performers engaged and gives average performers a clear incentive to push harder. The tradeoff is complexity—tiers require more careful design and accurate tracking to avoid disputes.

Here's how to build one that actually works.

What a tiered commission structure is

A tiered commission structure pays different commission rates depending on how much a rep sells. As performance crosses defined thresholds, the rate goes up.

Example:

If a rep's quota is $500K and they close $650K, here's how the payout works:

• First $500K at 8% = $40,000
• Next $125K (100–125% of quota) at 12% = $15,000
• Last $25K (above 125%) at 15% = $3,750
• Total commission: $58,750

Compare this to a flat 8% rate on the same $650K: $52,000. The tiered plan pays the rep an extra $6,750 for the same attainment—and costs the company roughly the same percentage of incremental revenue as additional margin from overperformance covers.

That's the logic behind tiered plans: overperformance is worth more margin, so you share more of it.

Why companies use tiers

The most immediate reason is motivation. A flat rate gives reps no reason to push past quota. Once they've hit their number, extra effort earns the same rate as the first deal of the quarter. Tiers change that math.

But motivation isn't the only reason. Tiers also:

Reward your best performers disproportionately. A rep who closes 140% of quota earns materially more per dollar than one who hits 90%. Over time, this shapes who stays and who leaves.

Protect against sandbagging. Without tiers, reps sometimes push deals into the next period once they've hit quota. Tiers make closing early in the next tier range more attractive than waiting.

Align compensation with margin. If your gross margin improves above a certain deal size or volume, tiers let you share that upside without changing the structure for average attainment.

According to Bridge Group's 2024 SaaS AE Metrics report, median AE OTE is $190K with a roughly 53:47 base-to-variable split—meaning the variable component is significant enough that tier design genuinely moves the needle for reps.

How to structure your tiers

Most tiered plans use one of two frameworks:

Quota-based tiers

Thresholds are set as percentages of quota attainment. This is the most common approach for B2B sales.

Quota-based tiers are easy to communicate and scale as quotas change each year. The same plan works whether a rep's quota is $400K or $900K.

Revenue-based tiers (dollar thresholds)

Thresholds are set at absolute dollar amounts, not percentages of quota.

Dollar-based tiers work for teams where deal size varies widely and quota isn't the right anchor—for example, transactional sales roles with high volume and variable deal sizes. The downside is that thresholds go stale as prices increase or market conditions shift.

For most B2B SaaS teams, quota-based tiers are simpler to administer and easier to explain.

How many tiers to use

Three tiers is the practical maximum for most sales teams. More than three creates calculation complexity that leads to disputes and shadow accounting—reps tracking their own commissions in parallel because they don't trust the official number.

Two tiers (a single accelerator at quota) is the simplest design and often the most effective. One rate below quota, one higher rate above it. Easy to explain, easy to verify.

Three tiers let you create a higher reward for significant overperformance (for example, above 150% of quota) without lifting the standard accelerator rate too much.

Four or more tiers are usually a sign that the plan is trying to solve too many problems at once. If you find yourself designing four tiers, consider whether a flat rate with a quarterly bonus might be simpler.

Setting the right accelerator rate

The most common question: how much higher should the accelerator rate be?

There's no universal answer, but a few guidelines:

The accelerator should feel meaningful. If your base rate is 10% and your accelerator is 10.5%, reps won't notice. A meaningful jump is typically 1.5x to 2x the base rate.

The accelerator shouldn't make overperformance unsustainable. If your base rate is 8% and you set the accelerator at 20%, you may find that a strong quarter creates a payout you didn't model for. Run the numbers at 120% attainment, 140% attainment, and 150% attainment before finalizing the rates.

Start conservative and adjust. It's easier to increase accelerators than to reduce them. A 1.5x accelerator that feels real (8% to 12%) is a reasonable starting point.

The payout cliff problem

One mistake that causes commission disputes: treating tiers as brackets instead of bands.

In a bracket structure, hitting 101% of quota changes the rate on all revenue, not just the incremental amount. A rep who closes $501K on a $500K quota suddenly earns 12% on everything, not just the last $1K.

That's mathematically unstable. It creates a cliff where marginal revenue triggers a large retroactive payout—and it's hard to explain to finance.

In a band structure (the correct approach), each tier's rate applies only to revenue within that band. The first $500K at 8%, the next $X at 12%, and so on. This is how the example at the top of this post works.

If you're building a tiered plan, be explicit about band vs. bracket. Most companies intend band-based tiers but implement bracket-based ones accidentally in spreadsheets.

Common design mistakes

Setting quotas too low so accelerators trigger automatically. If 80% of your team hits the first accelerator every quarter, it's effectively your base rate. Calibrate so the accelerator rewards genuine overperformance—ideally the top 20-30% of reps.

Too many tiers across multiple dimensions. Adding tiers by product line, by geography, and by attainment simultaneously creates a matrix that no rep can calculate in their head. Keep tiers to one dimension.

Changing tiers mid-year. Changing the structure after the year starts—even for good reasons—damages trust. Design for what you can commit to for 12 months.

Not modeling the payout at different attainment levels. Before finalizing, calculate total comp for a rep at 80%, 100%, 120%, and 150% of quota. If any scenario produces a number that surprises you, revise before launching.

Tracking tiered commissions accurately

The main operational challenge with tiered plans is that calculating them correctly requires knowing exactly where each rep stands relative to quota at the time of each deal.

In a spreadsheet, this means maintaining a running total per rep, per period, and recalculating every time a deal is added or adjusted. When deals get clawed back or modified, those recalculations cascade.

Tools like Carvd automate this. You upload your closed-won data, define your tier thresholds, and the app calculates each rep's payout based on their current attainment—no manual running totals. Reps can see their current tier and projected payout before the period closes.

That visibility matters. Shadow accounting—where reps maintain their own commission spreadsheets because they don't trust the official number—is a sign that the tracking system isn't working. Accurate, auditable calculations are the fix.

Tiered vs. flat commission: which to choose

Tiered plans aren't always better. A flat commission rate with a quota bonus is often the right answer for smaller teams.

If you're running a 5-rep team on a single straightforward quota and you have reasonable trust in your spreadsheet, a flat rate is fine. Complexity adds administrative overhead, and that overhead has a cost.

Tiered plans make sense when you have enough reps that differentiation matters, when overperformance is genuinely achievable (not a theoretical ceiling), and when you have the systems to track attainment accurately.
