Core answer: Commission = sales × rate, with three structures: flat (same rate on all sales), tiered (rate steps up at thresholds), and progressive (each bracket of sales earns its own rate — like tax brackets). On ¥500k sales with tiers "3% to ¥300k, 5% above": flat-style = 500k × 5% = ¥25k; progressive = 300k×3% + 200k×5% = ¥19k. Know which one your contract says — the difference is ¥6,000.

Progressive (超额累进)each bracket × its rate¥19,000
Base + commissionsalary + (sales × rate)¥3,000 + 3% = ¥18,000

Tiered vs progressive: read the clause

  • "销售额超过30万部分按5%" = progressive (only the excess gets 5%).
  • "达到30万后按5%计提" = ambiguous — demand clarification in writing; courts see both interpretations.
  • "跳档" = flat (hitting the tier retroactively re-rates everything) — common in渠道分销.

Worked examples

Example 1 — Real-estate agent. ¥3M sale at 2% total commission: agency takes ¥60k; agent's split (say 40%) = ¥24,000; minus platform/brand fees ≈ ¥19k take-home before tax.

Example 2 — SaaS sales. Base ¥8k + 8% of new ARR: closing ¥400k ARR = ¥32,000 commission + base. With a 1.2× accelerator above quota (¥300k): excess ¥100k × 9.6% = ¥9,600 vs ¥8,000 flat — accelerators reward overperformance deliberately.

Example 3 — Insurance. First-year commission on life policies runs 20–40% of first-year premium (renewals 2–5%): a ¥10k annual policy pays the agent ¥2,000–4,000 year one — why agents push premium-heavy products. Understand the incentive behind the advice.

Example 4 — Refund clawback. ¥50k sale returned next month: standard contracts claw back the ¥1,500 commission; check whether clawback survives resignation (usually yes for 3–6 months).

Common mistakes and myths

  1. Ignoring the tax treatment — commission is wage income (工资薪金) for employees (3–45% brackets) vs labor remuneration for independents (with 20% deduction then brackets); the same ¥10k nets differently.
  2. Assuming verbal tiers — "we'll take care of you at year-end" is not a compensation plan; get the tier table, base, clawback, and payment timing in writing.
  3. Gross vs net basis — commission on revenue vs on COLLECTED payment vs on gross profit: a 10% rate on collections arrives months later than on bookings.
  4. Cap shock — "uncapped commission" in recruiting ads sometimes hides a soft cap via decelerators; ask for the full curve.
  5. Double-counting team sales — overlapping credit (rep + manager + regional) can cost the company 1.5× on the same deal; clear crediting rules prevent both overpayment and disputes.
