What is a commission accelerator?

A commission accelerator raises your commission rate on everything you sell above 100% of quota, typically by 1.5× to 3×. It exists because the deal after quota is worth disproportionately more to the company, and because without it there is no financial reason to keep selling in December.

Earnings = (Quota × base rate) + (Above-quota sales × base rate × accelerator)

Accelerators are where high performers actually make money. On a plan with a 2× accelerator, going from 100% to 150% of quota pays as much again as the entire first 100% did — which is the whole economic argument for taking a high-variable sales job, and it disappears the moment a cap is introduced.

What an accelerator is worth

A $500,000 quota with $50,000 target commission (10% of quota) and a 2× accelerator above target.

Accelerators, tiers and the retroactive trap

An accelerator is a rate multiplier above quota. A tier is a band of revenue with its own rate. Plans commonly use both, and there are two ways to run tiers — a distinction worth thousands of dollars.

Marginal (progressive)Retroactive (cliff)
How it worksEach slice of revenue pays at its own rateReaching a tier re-rates all revenue at the higher rate
$600k sold, 4% to $500k then 6%(500k×4%)+(100k×6%) = $26,000600k × 6% = $36,000
How commonThe large majority of plansRare, and always deliberate
$10,000 from one ambiguous sentence. “6% for revenue above $500,000” is marginal. “Reps achieving $500,000 earn 6% on all revenue” is retroactive. If your plan is not explicit, ask in writing before the period starts.

Caps that are not called caps

1
“Payments above 150% of target require executive approval.” A cap with extra steps — approval is discretionary and can be refused.
2
Windfall or unusual-transaction clauses. Allow a single large deal to be re-rated downwards.
3
Mid-period quota adjustment rights. If quota can rise after you overachieve, the plan is capped in effect however it is labelled.
4
Decelerating tiers above target. A rate that falls above 120% attainment is a cap drawn as a curve.
5
Territory or account reassignment. Losing your best account in Q3 caps you as effectively as any clause.

Accelerator questions

Is this the same as tiered commission?

It is a type of tiered commission, usually focused on above quota performance.

What is a commission accelerator?

A multiplier applied to your commission rate on sales above 100% of quota, typically 1.5 to 3 times the base rate. It exists to keep reps selling after they have hit target, and it is where most of the upside in a sales plan lives.

How do you calculate accelerated commission?

Pay the base rate on everything up to quota, then apply the base rate multiplied by the accelerator to everything above it. On a $500,000 quota at 10% with a 2x accelerator, $600,000 of sales pays $50,000 plus $20,000 = $70,000.

What is a typical accelerator rate?

Between 1.5x and 3x the base rate is the normal range, with 2x the most common. Some plans use several accelerator tiers that increase further at 125% and 150% of quota.

Do accelerators apply to the whole amount or just the excess?

Almost always just the excess above quota. A plan that re-rates all revenue at the higher rate is called retroactive and is rare - check the exact wording, because the difference can be thousands of dollars.

Can a plan have an accelerator and a cap?

Yes, and many do. The accelerator raises earnings above target and the cap stops them at a ceiling, applied last. Such a plan behaves as uncapped up to the ceiling and like a flat salary beyond it.
