Commission, with the plan mechanics in the open
Commission plans hide their behaviour in the mechanics: whether tiers apply marginally or retroactively, what returns do to the base, how a split, a cap, a draw and a clawback queue up before anything is payable. This page runs the whole chain in that order and shows every step, including a tier breakdown, so the number at the end can be traced back to the plan that produced it.
Sales needed for a target commission
Disclaimer: This calculator gives estimates for general information only. It is not financial, medical or other professional advice. Your plan document governs: definitions of eligible sales, timing, splits, caps and clawbacks vary by employer and contract, and this page follows the settings you enter.
What this calculator does
It runs a commission plan the way payroll does, in a fixed order, and shows the working: sales are reduced by returns to the eligible base; the structure (flat, tiered or per-unit) earns commission on that base; a split credits your share; a cap trims anything above the plan maximum; the draw and any clawback come off; and what remains is payable, with base salary added for total compensation. In a tiered plan you also get the tier breakdown table, band by band, because a tiered total that cannot be decomposed cannot be checked. The solver at the foot of the card runs the same structure backwards from a target commission to the sales it requires.
Marginal versus retroactive tiers
This single choice is worth more than most rate negotiations. Under marginal tiers, each band of sales earns its own rate, like income tax brackets: the first $10,000 at 5%, the next $40,000 at 8%, everything above $50,000 at 12%. Under retroactive tiers, reaching a band re-rates the whole amount: the same $65,000 earns 12% on every dollar. On $65,000 of sales the marginal plan pays $5,500 and the retroactive plan pays $7,800; the $2,300 gap is not a rounding difference, it is the plan’s personality. Retroactive plans create cliffs worth knowing about: at $50,000 the retroactive plan pays $4,000, and one more dollar of sales re-rates everything at 12%, paying about $6,000. A dollar that earns two thousand is a dollar worth closing before the period ends, and worth suspecting when a colleague’s commission looks impossible.
How to use it
- Enter the plan as written, not as described. Offer letters summarise; plan documents define. The definition of eligible sales (booked, invoiced or paid), the timing of returns, and whether the cap applies before or after splits are all in the document, and each one moves the answer.
- Returns come off the base first. In a tiered plan a return does not just remove its own commission; it can pull the remaining sales down a band and re-rate the top slice at a lower rate. That is why returns sit at the top of the chain here, and why a cancellation-heavy month disappoints twice.
- A draw is timing, not income. A recoverable draw is the employer advancing your own future commission. It is deducted here so the payable figure is what actually arrives, and a string of draws against thin months is how representatives end a quarter owing their employer money, which the payable line will show as a negative if your draw and clawback exceed the commission.
- Quota attainment is context, not pay. Attainment (sales divided by quota) drives accelerators, rankings and sometimes employment decisions. It is shown when you enter a quota, but it changes no figure unless your plan’s rates themselves step up at attainment levels, in which case model those levels as tiers.
- Splits apply to the commission. Where two people share a sale, the usual mechanic is a credit split of the commission earned. This page applies your percentage after the structure and before the cap; if your plan instead splits the sales credit before tiers, enter your share of the sales in the sales field and leave the split at 100.
How it is calculated
- Eligible sales = sales – returns or cancellations (sales-based structures).
- Flat: commission = eligible sales x rate. Per unit: commission = units x amount per unit.
- Marginal tiers: each band’s sales (the part of eligible sales inside the band) x that band’s rate, summed. Each band’s commission is rounded to cents in the breakdown, and the total is the sum of the bands.
- Retroactive tiers: the rate of the highest band the eligible sales reach, applied to all eligible sales.
- Then, in order: split percentage applied; cap applied if the result exceeds it; draw deducted; clawback deducted. Commission payable is what remains, and total compensation adds the base salary for the period.
- Attainment = sales / quota x 100, on the sales as entered, before returns.
- Solver: the structure is inverted on gross commission before adjustments: directly for flat plans, band by band for marginal tiers, and for retroactive plans by finding the band whose rate produces the target inside that band, or the tier boundary where the plan’s jump carries commission past the target.
Worked examples
The flat plan. $80,000 of sales at 7.5% earns $6,000.00. Against a $100,000 quota that is 80.00% attainment, and with a $3,000 base salary the period’s total compensation is $9,000.00.
The tiered plan, both ways. Tiers of 5% to $10,000, 8% to $50,000 and 12% above, on $65,000 of sales. Marginal: $500 + $3,200 + $1,800 = $5,500.00, each band itemised in the tier breakdown. Retroactive: 12% on everything = $7,800.00. Same sales, same rates on paper, $2,300 apart in pay.
When the chain bites. The marginal plan again, but $5,000 of sales were returned: the eligible base is $60,000, the top band shrinks, and commission is $4,900. Split 50% with a colleague: $2,450. Less a $1,000 draw and a $200 clawback from a spring cancellation: payable is $1,250.00, and with a $2,500 base salary, total compensation is $3,750.00. Every step is ordinary; stacked together they take a $5,500 headline to a $1,250 payment, which is exactly why each step is shown.
The cap. $200,000 at a flat 10% earns $20,000, but a plan capped at $15,000 pays $15,000. Above the cap, extra sales earn nothing this period, a fact worth knowing in week one of the period rather than week twelve.
The solver. To take home a $5,500 gross commission on the marginal tiers above takes $65,000.00 of sales; on a flat 7.5% it takes $80,000. On the retroactive tiers, a $5,000 target cannot be reached smoothly at all: no band’s rate produces it inside its band, and the plan jumps past it the moment sales cross $50,000, which the solver reports as “just over $50,000”.
Reading your results
Decompose before you dispute. Most commission disagreements are one differing step: payroll applied returns you had not heard about, the split was applied to sales instead of commission, or the cap bit earlier than expected. The chain on this page lets you find the step: compare each line with the payslip until one diverges, and that line names the conversation to have. If your payable figure is negative, the plan has turned you into a debtor for the period, usually draws outrunning a slow patch plus a clawback landing together; the figure is real in most plan documents and is better seen here first.
Limitations
- The plan document governs. Eligible sales definitions, whether commission runs on booking, invoice or payment, refund windows, and cap and split mechanics all vary. This page implements the common forms of each mechanic and the order stated above; where your document differs, the document wins.
- Accelerators tied to attainment percentages (rates stepping up at 100% or 125% of quota rather than at sales bands) are modelled by entering the equivalent sales bands as tiers; a plan whose bands are defined purely by attainment needs its thresholds converted to sales first.
- Taxes and withholding are not modelled. Commission is usually taxed as wages with withholding; the payable figure here is gross, before any withholding, benefits or garnishments.
- Currency and periods are as entered. The page assumes every figure belongs to the same period and currency; mixing a monthly salary with a quarterly commission silently corrupts the total compensation line.
Frequently asked questions
What is the difference between marginal and retroactive tiers?
Marginal tiers pay each band of sales at that band’s rate, so only the sales above a threshold earn the higher rate. Retroactive tiers re-rate all sales at the highest band reached. On identical rates and $65,000 of sales the worked example pays $5,500 marginally and $7,800 retroactively. Marginal is the more common and the more predictable; retroactive creates cliffs at each threshold where a small amount of extra sales moves the whole base to a higher rate.
Why is my commission less than my rate times my sales?
Work down the chain: returns or cancellations reduced the base; in a tiered plan the blended rate is below the top rate your eye went to; a split credited part to someone else; a cap trimmed the top; and a draw or a clawback came off the end. Each of those is a line in this calculator’s results, in the order payroll applies them, so you can match your payslip line by line and find the step that differs.
What is a draw against commission?
A regular advance paid before commission is earned, recovered from later commission. A recoverable draw is a loan against your own future pay: generous in a slow month, reclaimed in the statement. A non-recoverable draw is effectively extra salary and is not deducted. This page deducts the draw you enter, modelling the recoverable kind; if yours is non-recoverable, leave the field empty.
Can a plan really claw back commission already paid?
Yes, where the plan document says so, most often when a customer cancels, returns or fails to pay within a stated window after the commission was paid. The clawback usually arrives as a deduction from a later period’s commission rather than an invoice, which is why it has its own line here. Whether a particular clawback is enforceable is a contract and local law question; that the arithmetic exists is not in doubt.
