Sales Commission Calculator

How sales commission is calculated

At its simplest, sales commission is sales amount times commission rate. If you close a $20,000 deal at a 10% rate, you earn $2,000 commission. The calculator handles this directly: enter the sales total, enter the rate, get the commission. For most flat-rate plans this is all you need.

Real-world comp plans add a few layers. Base salary plus commission is the dominant structure for full-time sales roles — you get a steady paycheck plus variable comp tied to performance. Quota is the sales target you’re measured against, and many plans accelerate commission rates above quota (an “accelerator” of 1.5x or 2x is common). Tiered plans pay different rates at different volume bands — a “ramp” structure that rewards consistency. The calculator handles the base case for all of these; for tiered or accelerated math, run the calculator separately for each tier and add the results.

Quota attainment is the percentage of your target you actually hit. $50K in sales against a $40K quota = 125% attainment, which usually unlocks accelerators in modern comp plans. 80% attainment usually triggers some kind of remediation conversation. 100% is the line most plans are built around — reps at 100% are profitable; reps below 100% over multiple periods typically don’t stay employed.

Common commission structures

Flat-rate commission

The simplest. One commission rate applies to all sales regardless of volume. Common in retail, real estate (typically 5-6% split between buyer and seller agents), and many channel partner programs. Easy to calculate and communicate; the calculator handles this case directly.

Tiered commission

Different rates for different sales bands. Common example: 5% on the first $50K of sales, 8% on the next $50K, 12% above $100K. Designed to reward higher producers proportionally more — and to incentivize incremental effort once a rep has cleared baseline. Run the calculator separately for each tier band and add the results to get total commission.

Accelerators (overages)

A base rate up to quota, then a higher “accelerated” rate on sales above quota. Most modern SaaS sales comp plans use this: 10% commission up to quota, then 15% (1.5x accelerator) or 20% (2x) above. Hitting 130% of quota under a 2x accelerator earns substantially more than hitting it under flat-rate — by design, to reward overachievement. Calculate: (quota × base rate) + ((sales − quota) × accelerated rate) for sales above quota.

Bonuses (SPIF / kicker)

One-time payments triggered by hitting a specific milestone — closing a particular product, hitting a goal by a deadline, ringing the bell on a defined campaign. Usually paid on top of regular commission. Often quarterly contests or product launches. Not modeled by the calculator — just add to the total separately.

Draw against commission

Some commission-only roles pay an upfront “draw” (advance) that you owe back if your commission for the period doesn’t cover it. Real estate brokerages and some independent rep arrangements use this. Functionally a base salary that has to be earned back — if your commission falls below draw, the deficit carries forward (or in some plans is forgiven, depending on contract).

Revenue vs profit / gross vs net commission

“Sales” in the calculator can mean different things depending on your plan. Some plans pay on gross revenue (top-line sales price), some on net revenue (after returns, refunds, discounts), and some on profit margin. Inside-sales SaaS roles typically pay on annual contract value (gross). Distributor/reseller roles often pay on margin. Check your plan document for which number to enter.

Typical commission rates by industry

Use these as anchor points. Actual rates vary enormously based on deal size, average sales cycle length, base salary level, market demand, and individual experience.

Inside sales (SaaS, B2B software)

• SDR / BDR: 3-6% on closed deals they sourced; or flat amount per qualified meeting
• AE (Account Executive): 8-12% on new logo deals; 5-8% on expansion/renewal
• Enterprise AE: 6-10% (lower % but bigger deals — $100K+ ACV)
• Customer Success / Renewal: 2-5% on renewed contracts

Outside sales (field, in-person)

• Industrial / B2B equipment: 5-10%
• Pharmaceutical sales: 8-12% plus bonuses
• Medical devices: 10-15%
• Insurance: 5-15% first year, 1-5% renewals (varies massively by product)

Real estate

• Residential real estate: 5-6% of sale price, typically split 50/50 between buyer’s and seller’s agents (so 2.5-3% per side), then split with the brokerage at 50-90% to agent
• Commercial real estate: 3-6% on lease/sale; complex split structures

Retail

• Retail floor: 1-5% of sales; many positions also have hourly base
• Car sales: 20-30% of dealer profit on each car (not 20% of sticker price)
• Furniture / high-ticket retail: 5-10%
• Jewelry: 6-10%

Channel / partner / affiliate

• Software resellers: 10-30% margin on reseller pricing
• Affiliate marketing: 5-50% (highly variable; SaaS often 20-30%, physical goods 5-15%, info products 30-70%)
• Manufacturer’s reps: 5-15%

Independent contractors / freelance closers

• High-ticket closer (sales-as-a-service): 10-20% on closed deals; sometimes 15% + bonuses
• Door-to-door sales: 10-30%; often weighted toward straight commission

OTE, base/variable mix, and accelerators

OTE (On-Target Earnings)

The total comp you should make if you hit exactly 100% of quota. Includes base salary plus expected commission at quota. A $150K OTE role with a 50/50 split is $75K base plus $75K expected commission at quota. Hitting 120% of quota would push total comp above OTE; hitting 70% would put you below OTE. OTE is the headline number in most sales job postings — it’s what you’ll earn if everything goes as expected.

Base/Variable mix

The split between guaranteed (base) and at-risk (commission) compensation. Common ratios:

• 70/30: 70% base, 30% commission. Common for customer success, technical sales, account management. Lower risk, lower upside.
• 60/40: Common for enterprise AEs and some senior reps. Moderate risk/reward.
• 50/50: Standard for most B2B inside sales. Significant skin in the game.
• 40/60 or 30/70: Aggressive commission-weighted. Common for door-to-door, high-ticket closers, transactional outside sales.
• 0/100 (commission-only): Some real estate, some independent contractors, channel partners. Highest risk, highest theoretical upside.

Pick the mix that fits your risk tolerance and confidence in the territory. New reps in a new market: prefer higher base. Experienced reps in a proven territory: lower base, higher variable for more upside.

Accelerators above quota

Most modern sales comp plans pay accelerated rates on sales above quota. A 1.5x accelerator means the commission rate jumps from, say, 10% to 15% on sales above your quota number. This is deliberately designed to make blowing through quota very lucrative — a rep at 130% of quota with a 2x accelerator can earn 50-60% more than a rep at exactly 100%. Some plans cap accelerators at 200% of quota; some go uncapped (rare but lucrative when they exist).

Decelerators below quota

Less common but real: some plans pay reduced rates below 80% of quota, dropping back to base rate above 80%. Designed to incentivize hitting threshold; functions as a soft floor below which the rep is essentially losing money relative to base.

Sales Commission Calculator FAQ

What’s a “good” commission rate?

Depends entirely on industry, deal size, and base salary. A 5% rate on $1M annual sales beats a 20% rate on $50K annual sales by 5x. Higher rates usually compensate for either harder sales (longer cycles, lower close rates) or smaller deal sizes. Compare rate × expected sales × close rate to other roles to find the better economic deal.

How is commission usually paid out?

Monthly (most common for inside sales), quarterly (common for enterprise), or per-deal (real estate, high-ticket closing). Some plans pay on signed contract; some on booked revenue; some on cash collected. The “on what” question matters as much as the rate — being paid 10% on cash collected with a 90-day net AR cycle is very different from 10% on contract signature.

Is commission taxed differently?

In the US, commission is typically taxed at a flat supplemental rate (22% federal) when paid as a bonus, or aggregated with regular wages if paid in the same paycheck — same total tax owed at year-end either way. In the UK and EU, commission is taxed as ordinary income at marginal rates. The withholding may look different from your regular paycheck but the annual tax burden is the same as if it were base salary.

What if I have a clawback in my contract?

A clawback is when the company reclaims paid commission if a deal cancels, refunds, or churns within a defined period (typically 6-12 months). Common in SaaS where customers can cancel quickly. The calculator gives you the commission you earned on the sale — your effective rate after clawbacks depends on your retention rate. If 20% of your deals get clawed back, your effective commission rate is 80% of your nominal rate.

How do I plan finances around variable commission income?

Build your fixed costs (rent, food, essential bills, minimum debt payments) on base salary alone. Treat commission as bonus income that goes toward savings, debt paydown, or discretionary spending. Reps who finance their lifestyle on expected commission almost always end up in trouble during slow quarters. The 50/30/20 budgeting framework adapts well here — make the 50% (needs) line up exactly with your base.

Can the calculator handle stacked accelerators?

Not in one calculation, but you can run it twice. For sales above quota with an accelerated rate: calculate the base portion (quota × base rate) using the calculator with quota as the sales input, then calculate the accelerated portion (excess × accelerated rate) by running the calculator again with (sales − quota) as the sales input. Add the two commission amounts together.
