Commission Calculator
Calculate sales commission from a flat rate or a tiered structure, with accelerators, caps and draws — and both the marginal and retroactive readings of the same tiers.
How to use this calculator
- Enter the sales amount.
- Choose a flat rate or set up as many tiers as your plan has.
- Set how the tiers apply. If the plan document does not say, look at both figures — the difference is what is at stake in asking.
- Add a cap or a draw only if the plan has one, and a base salary if commission sits on top of one.
How the calculation works
Flat: Commission = Sales × Rate
Marginal tiers: Commission = Σ (sales within each tier × that tier’s rate)
Retroactive tiers: Commission = Sales × the highest rate reached- Rate
- Commission percentage
- Tier
- A sales band with its own rate
Marginal tiering works exactly like progressive income tax: each tier’s rate applies only to the sales within that tier, so crossing a threshold never reduces total pay.
Retroactive tiering — "back to dollar one" — re-rates the whole period at the highest rate reached, so a single dollar over a threshold can be worth thousands. Plans use both and frequently do not say which.
A recoverable draw is an advance, not pay. It is subtracted from commission earned; it never adds to it.
Worked example
$50,000 in sales on a flat 6% rate
- Commission = 50,000 × 0.06 = $3,000.
Result: $3,000
$30,000 against 3% to $20,000 then 6% — read both ways
- Marginal: the first $20,000 earns 3% = $600, and the next $10,000 earns 6% = $600.
- That is $1,200, an effective rate of 4%.
- Retroactive: $30,000 reaches the 6% band, so 6% applies from the first dollar = $1,800.
- Identical sales, identical plan wording, $600 apart. The plan document decides which.
Result: $1,200 marginal, against $1,800 retroactive
What commission-based pay is for
Commission ties part or all of an employee’s pay directly to the revenue or sales they personally generate, rather than to hours worked or a fixed salary alone. The underlying logic is incentive alignment: an employer wants more sales, a commissioned employee is paid more for delivering them, and both sides’ interests point the same direction in a way a flat salary alone does not achieve as directly.
Common commission structures
Commission plans vary considerably in how the rate is applied and when it is paid out.
- Flat rate — the same percentage applies to every unit of sales, with no thresholds — the simplest structure to understand and to calculate.
- Tiered or graduated — the rate increases at defined sales thresholds. Under the marginal reading it works like a progressive tax bracket, each tier’s rate applying only to the sales within that tier.
- Retroactive tiering — also written "back to dollar one" — reaching a threshold re-rates every sale in the period at the higher rate, not merely the portion above it. On the same numbers this can pay half as much again as the marginal reading.
- Accelerator — a higher rate above a threshold, meant to reward overperformance. Whether it is marginal or retroactive is the question the plan document often leaves open.
- Cap — a hard ceiling on commission for the period. Past it, further sales earn nothing — which changes when people choose to close deals rather than how many they close.
- Draw against commission — the employee receives a guaranteed advance each pay period, which is later offset against commission actually earned — smoothing income for roles with long or unpredictable sales cycles.
- Residual or recurring commission — ongoing payment for as long as a sale continues generating revenue, common in subscription-based or renewal-driven businesses, rather than a single one-time payout.
OTE and total compensation
"On-target earnings," usually abbreviated OTE, is the total pay — base salary plus commission — a salesperson would earn by hitting exactly 100% of their assigned quota. It is the figure most often quoted in job postings, but it is a projection built on meeting quota, not a guarantee, and actual earnings for any individual can land well above or below it depending on performance.
Where commission is the norm
Commission structures are especially common in roles where individual performance is directly measurable and meaningfully variable — real estate, insurance, business-to-business sales, financial services, and much of retail sales. Roles with longer sales cycles or more collaborative, team-based selling tend to blend commission with a larger guaranteed base, since attributing a single sale to one person’s effort becomes harder.
Trade-offs for both sides
For an employee, commission offers uncapped upside compared with a fixed salary, at the cost of income that can vary significantly month to month based on factors not always within their control — market conditions, seasonality, or the length of a sales cycle. For an employer, commission-based pay scales cost with revenue rather than being a fixed overhead, which is attractive from a cash-flow perspective, but it also makes payroll costs harder to forecast precisely and can create pressure that pushes toward short-term sales at the expense of long-term customer relationships if the plan is not designed carefully.
What this assumes, and where it stops
Assumptions
- Commission is calculated on the gross sales amount entered, before any returns or chargebacks.
- A draw entered has already been paid to you during this period, and is recoverable — the outstanding figure assumes the case that carries a balance forward.
Limitations
- Does not model clawbacks on refunds or cancellations, split credit across a team, product-level rate differences, or multi-year deal amortisation.
- Tax is not applied. Commission is usually withheld at a supplemental rate rather than your marginal rate, so the amount reaching your account differs from the figure here in both directions.
- It cannot tell you whether your plan is marginal or retroactive. That is in the plan document, and if the document does not say, that is the finding.
Common questions
How does tiered commission work?
It depends which of two readings your plan uses. Under marginal tiering — the common one, and the default here — each portion of your sales is paid at the rate for the tier it falls into: if tier 1 pays 3% up to $20,000 and tier 2 pays 6% from $20,000, selling $30,000 earns 3% on the first $20,000 and 6% on the next $10,000. Under retroactive tiering the 6% would apply to the whole $30,000. Set the option above to see both.
What does "back to dollar one" mean?
It is retroactive tiering. Once you reach the stated threshold, the higher rate applies to all your sales for the period rather than only the portion above it. A plan that states an accelerator without saying whether it applies from the first dollar has left the largest single variable in the calculation undefined, and that is worth settling in writing before the period closes rather than after.
Do I have to pay back a draw?
If it is recoverable, yes — it is an advance, recovered from the commission you earn, and an unrecovered balance normally carries into the next period. If it is non-recoverable it acts as a guaranteed minimum and the shortfall is written off. Many plans use non-recoverable draws during a ramp and recoverable ones afterwards, so the answer can change partway through a year.
Why was my commission taxed so heavily?
It usually was not taxed more — it was withheld more. Commission is generally treated as supplemental pay and withheld at a flat rate rather than at the rate your allowances imply, which often overshoots. The actual tax is settled when you file. This calculator shows gross commission and does not model withholding.
What is OTE?
"On-target earnings" — the total pay (base plus commission) a salesperson would earn by hitting 100% of their sales quota. It is the figure usually quoted in job postings, and is not a guarantee, since it assumes quota is met.
