Sales Commission Accelerators

Understand marginal and retroactive sales commission accelerators, with worked examples and a free compensation-plan comparison tool.

What is a sales commission accelerator?

An accelerator increases the payout rate after a performance threshold, often 100% of quota. It is designed to reward overachievement. The precise calculation depends on whether the higher rate applies only to sales above the threshold or retroactively.

Marginal accelerator example

Assume 5% commission up to €100,000 in eligible sales and 8% above it. At €130,000, payout is €100,000 × 5% + €30,000 × 8% = €7,400. Excel: =MIN(B2,100000)*5%+MAX(0,B2-100000)*8%.

Retroactive accelerator example

If a plan pays 8% on all eligible sales once €100,000 is exceeded, the same €130,000 produces €10,400. This creates a discontinuity at the threshold. Make that rule explicit and stress-test the expense impact.

How finance should assess accelerators

Compare payouts at multiple attainment levels, including 99%, 100%, 101%, 125%, and 150%. Check whether payout increases are proportionate to incremental gross profit and whether caps or decelerators are appropriate.
