Commission Calculator
Marginal tiers, not cliffs — always ask which.
Work out Commission. Marginal tiers, not cliffs — always ask which. Counts the thing everyone forgets to count.
Measured from the threshold, not from zero
Commission earned
12,500
72,500 total compensation · 125% of quota
These tiers are marginal, not cliff: crossing a boundary raises the rate on the next dollar only, never retroactively on everything below it. A cliff plan would pay the top rate on the whole amount, and the difference at the boundary is large enough that it is always worth asking which structure a plan actually uses.
How the Commission Calculator works
Tiered commission on sales above a threshold, with base salary and quota attainment alongside. The tiers here are marginal: crossing a boundary raises the rate on the next pound only, never retroactively on everything below it.

Marginal tiers against cliffs
In a marginal tier structure, each rate applies only to the sales inside its band. Crossing a boundary raises the rate on the next pound and changes nothing about what came before. That is how this page calculates and how most plans are written.
A cliff structure applies the achieved rate to everything. Reaching a threshold retroactively repays all prior sales at the higher rate, which produces an enormous jump at the boundary — and an enormous incentive to pull deals forward or push them back across it.
The difference at the boundary is large enough that it is always worth asking which structure a plan uses before signing. Plan documents are not always explicit, and the behaviour a cliff produces near quarter-end is a well-known and largely unwanted feature.
Quota, accelerators and on-target earnings
Quota attainment — sales as a percentage of target — is the number most plans are actually built around. Accelerators raise the rate above 100%, sometimes substantially, on the reasoning that the marginal deal above quota is worth more to the business than the one below it.
On-target earnings is base plus commission at exactly 100% attainment. It is the figure recruiters quote and it is a projection rather than a promise. The question worth asking is what proportion of the team actually hit quota last year, and the answer is often well under half.
Decelerators exist at the other end, reducing the rate above a very high attainment to cap windfalls from an unusually large deal. They are unpopular for obvious reasons and are frequently replaced by a per-deal cap, which achieves the same thing with less resentment.
When commission is earned, and when it can be taken back
Plans differ on the trigger: on order, on invoice, or on customer payment. Paying on collection shifts credit risk onto the salesperson, who has no control over whether a customer pays. Paying on order shifts it entirely to the company. Most plans settle on invoice as a compromise.
Clawback provisions reclaim paid commission if a customer cancels, refunds or fails to pay within a window. Six to twelve months is common in subscription businesses, and it means commission received is not final for the better part of a year.
Renewal commission is usually paid at a lower rate than new business, and sometimes not at all. Where renewals carry nothing, the incentive to service existing accounts disappears entirely — a structural problem that subscription businesses tend to discover through their churn numbers rather than their plan design.

Frequently asked questions
How is sales commission calculated?
As a percentage of sales, often only above a threshold and often at rates that rise in tiers. £250,000 of sales with a £100,000 threshold leaves £150,000 commissionable, split across the tiers.
What is the difference between a tiered and a cliff commission plan?
In a tiered plan each rate applies only to the sales inside its band. In a cliff plan, crossing a threshold applies the higher rate to everything. Cliffs pay far more at the boundary and are correspondingly rarer.
What is quota attainment?
Sales as a percentage of your target. It usually drives accelerators — rates that step up above 100% — and it is the number most compensation plans are actually built around.
What is an accelerator?
A higher commission rate that applies above quota, designed to reward over-performance disproportionately. It is why the top tier here carries the highest rate.
What is a commission draw?
An advance against future commission, guaranteeing a minimum income. A recoverable draw must be paid back from later commission; a non-recoverable one does not. The difference matters enormously in a bad quarter.
When is commission actually earned?
That is set by the plan, and it varies: on order, on invoice, or on customer payment. Plans that pay on collection shift the credit risk onto the salesperson, and clawback clauses on refunds are common.
What is on-target earnings?
Base salary plus the commission you would earn hitting exactly 100% of quota. It is the figure recruiters quote, and it is a projection rather than a guarantee — ask what proportion of the team actually achieves it.
What is a clawback in a commission plan?
A provision reclaiming paid commission if a customer cancels, refunds or fails to pay within a period. Clawback windows of six to twelve months are common in subscription businesses.
How does commission work on a renewal?
Usually at a lower rate than new business, on the reasoning that renewals require less effort. Where renewals carry no commission at all, the incentive to service existing accounts disappears, which plans often discover the hard way.
What is a decelerator?
A reduced rate above a very high attainment threshold, used to cap windfall payouts from an unusually large deal. It is unpopular for obvious reasons and is often replaced by a per-deal cap instead.
When should commission be paid?
The plan decides, and the options are on order, on invoice, or on collection. Paying on collection shifts credit risk to the salesperson; paying on order shifts it to the company. Most plans compromise on invoice.
Is commission included in holiday pay?
In jurisdictions using an average-earnings test for holiday pay, regular commission generally is. This has been contested and decided in favour of inclusion in several significant cases.
