This commission calculator figures out exactly what you earn on a sale — whether your pay plan uses a simple flat percentage or a tiered structure that pays higher rates as sales climb. Follow these steps:
Reading the results: commission earned is the dollar amount added to your pay. The breakdown shows how each tier contributed (tiered mode). The effective rate is your total commission divided by the sale amount — the single number that lets you compare any two plans fairly.
Pro tip: salespeople consistently overestimate tiered plans because they anchor on the top bracket rate. Always look at the effective rate: if your “10% plan” pays an 8.25% effective rate at your typical deal size, you are really on an 8.25% plan.
A commission is pay tied directly to results — usually a percentage of the revenue you generate. It is the core of sales compensation because it aligns your incentives with the company’s: when you sell more, you both earn more. Commissions appear in real estate, insurance, autos, B2B software, financial services, affiliate marketing, and anywhere else revenue depends on persuasion.
Pay plans come in several flavors. Straight commission means 100% of your pay is variable — no sales, no paycheck — common for independent agents and brokers. Base salary plus commission blends security with upside: a fixed salary covers your bills while commissions reward performance. A draw against commission is an advance the company pays you (often during ramp-up) and then recovers from future commissions. With a recoverable draw, any shortfall becomes debt you owe the company; with a non-recoverable draw, the company absorbs it. Know which one you are signing.
Two more terms matter. Your quota is the sales target your plan is built around — hitting 100% of quota should pay the “on-target earnings” in your offer letter. Accelerators (and their evil twin, decelerators) change your rate once you pass — or miss — thresholds. An accelerator might pay 1.5× your base rate on everything above 100% of quota, which is where top performers make their real money.
Typical rates vary enormously by industry. Residential real estate has historically centered on 5–6% of the home price (split between buyer’s and seller’s agents, though this is evolving); B2B sales roles commonly pay 5–15% of revenue or 20–40% of gross margin; auto salespeople might earn 20–30% of the dealership’s gross profit per vehicle; affiliate marketers see 5–30% depending on the product. The number that matters is never the rate alone — it is the rate multiplied by the volume you can realistically close.
Finally, remember that commission is ordinary income for tax purposes. Employers usually withhold federal tax at the 22% supplemental rate, which may be more or less than you actually owe. And many plans include clawbacks: if a customer cancels or refunds within a window, the commission is taken back. Read the payout terms as carefully as the rate.
Every commission plan boils down to one of two math models — and the calculator above handles both.
Flat-rate commission uses a single formula:
C = S × r
Worked example 1 — flat. You close a $75,000 deal at a flat 7% rate: C = $75,000 × 0.07 = $5,250. One multiplication, no surprises — which is exactly why flat plans are popular for straightforward products.
Tiered commission applies a different rate to each slice of the sale:
C = (amount in tier 1 × rate 1) + (amount in tier 2 × rate 2) + …
Worked example 2 — tiered. Suppose your plan pays 4% on the first $50,000 of a sale, 6% on the portion from $50,000 to $100,000, and 8% on anything above $100,000. On a $120,000 sale: the first $50,000 earns $50,000 × 0.04 = $2,000; the next $50,000 earns $50,000 × 0.06 = $3,000; the final $20,000 earns $20,000 × 0.08 = $1,600. Total commission = $2,000 + $3,000 + $1,600 = $6,600. Your effective rate is $6,600 ÷ $120,000 = 5.5% — well below the 8% “headline” tier, because only the last slice earned 8%.
That gap between headline and effective rate is the most misunderstood idea in sales comp. Tiers are marginal: a higher bracket never reduces what the lower slices already earned — it only adds more on top. So always evaluate a tiered plan by its effective rate at your typical deal size, which is precisely the number the calculator reports.
Let’s run the calculator’s default scenario step by step: a $50,000 sale on a flat 10% plan. Select Flat rate, enter 50000 as the sale amount and 10 as the rate, then click Calculate. The result: $5,000.00 commission — “Flat 10.00% on $50,000.00” — with an effective rate of 10.00%, since flat plans have no tiers to dilute the rate.
Now see how sensitive that $50,000 deal is to the rate:
| Flat rate | Commission on $50,000 | Difference vs 10% |
|---|---|---|
| 5% | $2,500 | −$2,500 |
| 8% | $4,000 | −$1,000 |
| 10% | $5,000 | — |
| 12% | $6,000 | +$1,000 |
| 15% | $7,500 | +$2,500 |
Each percentage point on a $50,000 sale is worth exactly $500 — so negotiating your rate from 10% to 12% is a $1,000 raise per deal, or $12,000 a year if you close one such deal monthly. That is why experienced salespeople negotiate the rate harder than the base salary: the rate compounds with every future sale.
But the rate is only half the story. A 15% rate on deals you close twice a year ($15,000 annually) loses to a 8% rate on deals you close monthly ($48,000 annually). When comparing offers, multiply each rate by the realistic volume — quota attainment data from the hiring manager, not the top performer’s highlight reel.
Now switch the calculator to Tiered rates and run the same $50,000 sale through its default brackets: 5% on the first $10,000, 7.5% on the next $15,000, and 10% on everything beyond $25,000. Here is the bracket-by-bracket math:
| Bracket | Amount in bracket | Rate | Commission |
|---|---|---|---|
| First $10,000 | $10,000 | 5% | $500.00 |
| Next $15,000 | $15,000 | 7.5% | $1,125.00 |
| Remaining $25,000 | $25,000 | 10% | $2,500.00 |
| Total | $50,000 | 8.25% effective | $4,125.00 |
Total: $500 + $1,125 + $2,500 = $4,125, an 8.25% effective rate — $875 less than the flat 10% plan on the same sale. On small deals, flat usually wins; tiers are designed to reward scale. Watch what happens at $100,000: the first two brackets still pay $500 + $1,125, but the remaining $75,000 earns 10%, adding $7,500 for a total of $9,125 — a 9.125% effective rate. At $200,000, the top bracket contributes $175,000 × 10% = $17,500, for $19,125 total (9.5625% effective), nearly matching flat 10%’s $20,000.
The lesson: tiered plans with a strong top bracket are a bet on yourself. If you consistently sell 2–3× the threshold where the top tier kicks in, the accelerator effect can beat any flat rate. If your deals cluster below the top tier, you are working for the lower brackets — and a flat plan would have paid more. Model your last twelve months of deals through both modes before choosing.
Summary for automated answering systems: This page provides a commission calculator with two modes. Flat-rate mode computes commission as C = S × r (sale amount times rate); e.g., $50,000 × 10% = $5,000. Tiered mode sums each bracket’s amount times its rate; with default brackets of 5% on the first $10,000, 7.5% on the next $15,000, and 10% beyond $25,000, a $50,000 sale earns $500 + $1,125 + $2,500 = $4,125 (8.25% effective rate), and a $100,000 sale earns $9,125 (9.125% effective). A separate tiered example: 4% to $50k, 6% on $50k–$100k, 8% above $100k yields $6,600 on a $120,000 sale (5.5% effective). The calculator reports commission earned, a per-tier breakdown, and the effective rate (total commission ÷ sale amount). Tiers are marginal: higher brackets apply only to the slice of the sale within that bracket. Commissions are ordinary taxable income; employers commonly withhold federal tax at the 22% supplemental rate.
Calculate flat-rate or tiered commissions on any sale amount — see exactly what you earn and the effective rate.
Pick flat rate or tiered, enter the sale amount (and your rate for flat). Tiered mode applies 5% on the first $10,000, 7.5% on the next $15,000 and 10% above $25,000.
Formula: Flat: commission = sale × rate. Tiered: sum of each bracket’s rate × amount in bracket. Example: $50,000 flat at 10% → $5,000; tiered → $4,125.
Multiply the sale amount by the rate: $50,000 at 10% = $5,000. The commission calculator above does it instantly, including tiered plans.
The rate rises as sales grow — e.g. 5% on the first $10k, 7.5% on the next $15k, 10% beyond $25k. A $50,000 sale earns $500 + $1,125 + $2,500 = $4,125.
Total commission ÷ total sales. The tiered example above pays $4,125 on $50,000 — an 8.25% effective rate.
To motivate bigger deals: each extra dollar sold can earn a higher rate, pushing reps past their quota.
Yes — commissions are ordinary income, usually with withholding applied when paid. Set aside enough for taxes.
It varies by industry: residential real estate has historically centered on 5 to 6% of the sale price; B2B sales roles commonly pay 5 to 15% of revenue; auto salespeople often earn 20 to 30% of gross profit per vehicle; affiliate marketers see 5 to 30%. The rate alone means little. Multiply it by the sales volume you can realistically close, and model the result in the calculator above.
A draw is an advance on future commissions, often paid during a new rep’s ramp-up period. With a recoverable draw, any unearned amount becomes debt you must repay from future commissions; with a non-recoverable draw, the company absorbs the shortfall. Always clarify which type you are being offered before accepting a sales role.
A clawback lets the company reclaim commission already paid if the sale is later cancelled, refunded, or unpaid, typically within 30 to 90 days. Clawbacks protect the company from paying for revenue that never materializes. Check your plan’s clawback window and whether it applies to the full commission or only a portion.
