How tiered commission works
Most sales commission plans aren't one flat percentage — they're tiered (also called graduated): the rate climbs as your sales climb. The critical point is that tiers are marginal, exactly like income-tax brackets. You don't earn the top rate on everything; you earn each tier's rate only on the sales that fall inside that tier. That single misunderstanding is responsible for most commission-paycheck surprises.
Worked example
Take a plan with three tiers — 5% on the first $10,000, 8% on sales from $10,000 to $20,000, and 10% above $20,000 — and a rep who closes $25,000:
| Tier | Sales in tier | Rate | Commission |
|---|---|---|---|
| $0 – $10,000 | $10,000 | 5% | $500.00 |
| $10,000 – $20,000 | $10,000 | 8% | $800.00 |
| $20,000+ | $5,000 | 10% | $500.00 |
| Total | $25,000 | $1,800.00 |
The effective rate is $1,800 ÷ $25,000 = 7.2% — well below the headline 10%. Compare with a flat 5% plan ($1,250): the tiered plan wins here by $550. But at only $8,000 in sales, the tiered plan pays just $400 (5% on everything in the first tier) — barely different from flat. Always evaluate a plan at your realistic volume, not at the top rate.
Quotas, accelerators, and caps
In real plans, tiers usually orbit a quota — your target for the period. A common structure pays a base rate up to 100% of quota, then an accelerator (a higher rate, sometimes 1.5× or 2× the base rate) on everything above quota. You can model that here: set a tier boundary at your quota number and a higher rate on the open-ended tier above it. Watch for the mirror image too — caps (maximum commission per period) and decelerators, which quietly undo the upside the accelerator promised. If your plan document mentions either, model them before you sign.
Draws, clawbacks, and timing
Two more terms that move real money. A draw against commission is an advance — the company pays you monthly and deducts it from commissions you later earn. A recoverable draw can leave you owing the company if commissions fall short; a non-recoverable draw is effectively a floor. Clawbacks reverse commissions when a deal cancels or a customer churns inside the clawback window — common in SaaS and insurance. None of these change the marginal math above, but they change when cash actually lands, which is what your budget cares about.
Taxes: the 22% withholding surprise
For federal withholding, commissions are supplemental wages: employers typically withhold a flat 22% for federal income tax on the first $1 million of supplemental wages in a year (IRS Publication 15, 2026), instead of your normal W-4 withholding rate. Your actual tax liability at filing time is identical to salary income — but the withholding can make commission checks feel smaller than the gross suggests. Add a base salary in the calculator to see total estimated earnings, then run the result through a take-home pay calculator to see what survives withholding.

Frequently asked questions
How does tiered (graduated) commission work?
Only the sales inside each tier earn that tier's rate — like tax brackets. If the plan pays 5% on the first $10,000 and 8% above that, then $25,000 in sales earns 5% on the first $10,000 ($500), 8% on the next $10,000 ($800), and 10% on the final $5,000 ($500), for $1,800 total — an effective rate of 7.2%, not 10%.
What is the difference between a tiered rate and a flat rate?
A flat rate pays one percentage on everything (5% of $25,000 = $1,250). A tiered plan usually pays less on early sales and more as you climb, rewarding bigger numbers — in the example above, the tiered plan pays $1,800 vs. $1,250 flat at 5%. The trade-off: tiered plans can pay less than a generous flat rate at low volumes, so always compare at your realistic sales level.
What is a quota, and how does it relate to tiers?
A quota is a sales target, often monthly or quarterly; tiers are the pay rates applied around it. Many plans pay a base rate up to quota, then an accelerated rate (an 'accelerator') above 100% of quota. You can model that here by setting a tier boundary at your quota with a higher rate on the tier above it.
What does 'draw against commission' mean?
A draw is an advance the employer pays you (often monthly) that is later deducted from your earned commission — it's a loan against future commissions, not extra pay. A recoverable draw must be repaid out of commissions (or, depending on the agreement and state law, back to the employer); a non-recoverable draw is effectively a guaranteed minimum. This calculator doesn't model draws.
Is commission taxed differently from salary?
Commission is supplemental wages for federal withholding: employers generally withhold a flat 22% for federal income tax on supplemental wages up to $1 million (IRS Publication 15, 2026), rather than your normal W-4 rate — though your actual tax at filing time is the same as any other income. State rules vary.
