Calculate your sales commission across four common compensation structures — flat rate, tiered (graduated), accelerator, and draw against commission. Enter your sales figures and commission terms to see your total earnings, effective rate, and per-tier breakdown in real time.
Pro tip: In a tiered commission plan, only the revenue within each bracket earns at that bracket’s rate — just like income tax brackets. Earning $150K in sales with tiers at 5%/8%/12% does NOT mean 12% on the whole amount.
Commission Structures Explained: Flat, Tiered, Accelerator
Sales commission structures determine how reps earn money on the revenue they generate, and the differences between models matter far more than most salespeople realise. A flat rate structure pays the same percentage on every dollar sold — simple to understand and easy to forecast, but it offers no extra incentive for exceeding targets. Tiered (graduated) commission works like income tax brackets: each slice of revenue earns at the rate assigned to its bracket. For example, the first $50,000 may earn 5%, the next $50,000 earns 8%, and anything beyond $100,000 earns 12%. Only the revenue inside each bracket is multiplied by that bracket’s rate, so crossing a new threshold never retroactively raises the rate on dollars already earned below it. Accelerator plans simplify the tiered concept into two zones: a base rate up to quota and an accelerated rate on every dollar above quota. This model is popular in SaaS and enterprise sales because it creates a powerful incentive to exceed target without the complexity of multiple tiers.
How to Calculate Tiered Commission Step by Step
Tiered commission is the structure that trips up most salespeople because each bracket must be calculated independently and then summed. Start by listing your tiers from lowest to highest. For each tier, determine how much of your total sales falls within that bracket — this is the taxable amount for the tier. Multiply that amount by the tier’s rate to get the commission earned in that bracket. Repeat for every tier, then add the results together. Suppose your plan pays 5% on the first $50K, 8% on $50K–$100K, and 12% above $100K, and you sold $130,000. Tier 1 earns $50,000 × 5% = $2,500. Tier 2 earns $50,000 × 8% = $4,000. Tier 3 earns $30,000 × 12% = $3,600. Your total commission is $10,100, and your effective rate is 7.77% — not the 12% you might have expected if you only looked at the highest tier. This calculator handles these bracket calculations automatically, including a visual staircase chart showing exactly how much each tier contributes.
Draw Against Commission: How It Works
A draw against commission is essentially an advance on future commissions that guarantees a minimum income each pay period. The employer pays the rep a fixed “draw” amount (say $3,000 per month) regardless of performance. At the end of the period the company calculates actual commissions earned. If commissions exceed the draw, the rep keeps the surplus. If commissions fall short, the shortfall may or may not be carried forward depending on whether the draw is recoverable or non-recoverable. Recoverable draws accumulate as a debt the rep must repay through future commissions — a model common when ramping new hires. Non-recoverable draws reset each period, functioning more like a base salary floor. This calculator shows both the gross commission and the net amount after subtracting the draw, so you can immediately see whether you are above or below break-even for the period.
Average Commission Rates by Industry
Commission rates vary widely depending on the industry, deal size, and sales cycle length. Real estate agents typically earn 2.5–3% of the sale price per side, with total transaction commissions of 5–6% split between buyer and seller agents. Insurance brokers may earn 5–20% on first-year premiums for life insurance and 10–15% for property and casualty renewals. SaaS sales reps commonly see 10–15% base commission on annual contract value, with accelerators pushing effective rates to 20% or more above quota. Retail commissions tend to be lower, ranging from 1–10%, while affiliate marketing programmes offer anywhere from 5–50% depending on the digital product. When evaluating a commission plan, always calculate your blended (effective) rate across realistic sales volumes rather than focusing on the headline rate at the top tier.
Commission Calculator FAQ
What is an effective commission rate? It is the total commission earned divided by total sales, expressed as a percentage. In a tiered plan, the effective rate will always fall between your lowest and highest tier rates. Can I use this calculator for real estate? Yes — enter the property sale price as total sales and your agent split percentage as a flat rate. How does the accelerator model differ from a two-tier plan? Functionally they are similar, but accelerator plans are typically defined by a quota rather than a dollar bracket. The base rate applies to all sales up to quota; the accelerated rate kicks in only after quota is met. Does this handle retroactive tiered commission? This calculator uses graduated (marginal) tiers, which is the most common structure. In a retroactive model the highest tier rate applies to all sales once a threshold is crossed; to approximate that, use the flat rate mode with the applicable rate. What taxes apply to commission income? Commission income is taxed as ordinary income for W-2 employees. Independent contractors (1099) must also pay self-employment tax of roughly 15.3%. Our subscriber-only tax impact section estimates take-home under both scenarios.

Frequently Asked Questions
What is a typical sales commission rate?
Flat-rate commissions typically run 5% to 10% for transactional sales and 15% to 25% for high-ticket or complex sales. SaaS AE commissions average 8% to 12% of annual contract value. Channel and affiliate commissions range from 3% to 30% depending on category and margin.
How does a tiered commission plan work?
Tiered plans work like income tax brackets. Only the revenue within each bracket earns at that bracket's rate. A rep hitting $150K in sales with tiers at 5% up to $50K, 8% up to $100K, and 12% beyond earns $2,500 + $4,000 + $6,000 = $12,500, not 12% of the full $150K.
What is a draw against commission?
A draw is a guaranteed advance against future commissions. Recoverable draws are subtracted from commissions earned in later periods, effectively making them a loan. Non-recoverable draws function as a salary floor and are not repaid even if commissions fall short.
What is an accelerator in a sales comp plan?
An accelerator is a higher commission rate that kicks in after a rep hits quota. A typical plan might pay 8% up to quota and 12% above. Accelerators reward top performers and are designed to keep reps selling aggressively through the end of the period.
Is commission subject to higher tax withholding?
In the US, supplemental wages including commission are subject to a 22% federal withholding rate (or 37% for amounts over $1M annually). This often differs from a rep's marginal rate, so commission-heavy earners may owe or receive a meaningful refund at tax time.
