How to calculate sales commission

What is sales commission?

Sales commission is performance-based pay: a percentage of the revenue, margin, or contract value a rep brings in. It can be a rep's entire income, or it can sit on top of a base salary. The percentage, the base it applies to, and what gets deducted before payout are all negotiable — which is why two reps with the same “8% commission” can take home very different amounts.

The commission formula

For a flat structure, commission equals sales amount multiplied by commission rate. A rep who closes $250,000 at a flat 6% earns $15,000. Under a tiered structure — 4% to $50,000, 6% to $150,000, 8% beyond — the same $250,000 earns $16,000, because only the sales inside each bracket take that bracket's rate.

Doing this by hand every month is where errors creep in. Track your commissions automatically with a CRM that logs closed-won deals and applies your comp plan to each one.

How tiered (progressive) commission works

Progressive tiers reward volume without repricing earlier sales. Each bracket has a threshold and a rate; sales fill the lowest bracket first, then spill into the next. A common mistake is applying the top rate to the whole total, which overstates earnings — at $250,000 that would be $20,000 instead of $16,000. Sales above the highest bracket keep earning the highest bracket's rate.

The practical consequence is that your effective rate always sits below your top rate. The rep above has an 8% top tier but takes home 6.40% of what they sold. If someone quotes you a commission plan by its highest number, work out the effective rate on a realistic sales figure before you decide whether the offer is good.

Commission structures compared

Five structures cover almost every plan you will meet. Most real plans are a combination — a base salary with tiered commission and a recoverable draw is entirely normal — so it helps to recognise each piece on its own.

Flat commission pays one rate on everything you sell. It is used where deals are similar in size and the sales cycle is short: recruitment placements, straightforward retail, agency work. It is the easiest to verify, which is its real advantage — you can check your own pay in one multiplication. The trade-off is that it gives you nothing extra for an exceptional quarter, so it suits steady producers more than streaky ones.

Tiered commission raises the rate as you clear thresholds. Software and enterprise sales lean on it because it makes the last deal of a quarter worth more than the first, which is exactly the behaviour a sales manager wants to buy. It favours high performers and is the structure most likely to be misrepresented, because the headline number is the top tier and almost nobody earns at the top tier across their whole book.

Base plus commission pays a guaranteed salary with commission on top. Retail, financial services, and any long sales cycle use it, because nobody can wait nine months for a first paycheque. It buys you stability at the cost of rate: employers who carry the risk of a slow month pay a lower percentage than those who do not. If you are comparing a base-plus offer against a pure commission offer, price the base in — a $40,000 base is worth a great deal of commission percentage.

Draw against commission advances you money before you earn it, then settles up. It exists to smooth income in businesses with lumpy or seasonal sales — insurance, mortgages, enterprise deals. Whether it helps or hurts depends entirely on one word in your contract, covered in the next section.

Residual commission pays you repeatedly for the same sale, usually while the customer keeps paying. Insurance renewals, SaaS subscriptions, and managed services work this way. The first year looks poor next to a one-off commission plan and the fourth year looks excellent, so residual plans reward staying put. Read the vesting terms: many plans stop paying residuals the moment you leave, which quietly converts your book of business into the company's asset.

Recoverable and non-recoverable draws

A recoverable draw is a loan against future commission. Take a $3,000 draw and earn $5,000 in commission, and you are paid the $2,000 difference. Earn only $1,000 and you now owe $2,000, which is carried forward and taken out of next month. In a bad stretch a recoverable draw builds a debt you pay back out of your future good months.

A non-recoverable draw is a guaranteed floor you keep whatever happens. Take a $3,000 non-recoverable draw and earn $5,000, and depending on the plan you are paid either the $5,000 or the full $8,000 — this is worth pinning down in writing, because both versions exist. Earn nothing and you still keep the $3,000, with no debt carried forward.

Confusing the two produces the wrong net pay for insurance, mortgage, and enterprise reps, and it is the single most common source of pay disputes. One critical detail: brokerage fees and fixed deductions come out of commission, never out of a guaranteed base. If a deduction is reducing money that was promised to you unconditionally, something is wrong.

How real estate commission splits work

Real estate commission is split twice, and missing the second split is why agents are surprised by their first cheque. The seller agrees a total commission with the listing brokerage. That total is divided between the listing side and the buyer's side. Then each agent divides their side again with their own brokerage.

The headline was 5%. The agent who did the work received 1.75%. Newer agents often sit on a 50/50 split, which brings that to $5,000, and many brokerages take desk fees, transaction fees, and franchise fees before the agent sees anything. A cap arrangement, where the brokerage stops taking a share once you have paid them a set amount in a year, changes the maths substantially for high producers.

Two further points. Commission is always negotiable, whatever anyone tells you — and following industry-wide legal settlements in the United States, buyer-side compensation is now negotiated more openly than it once was. And the split is applied to the sale price, so a price reduction cuts the commission proportionally on both sides.

Average commission rates by industry

Rates cluster by industry because they track deal size, sales cycle length, and how much of the outcome the rep actually controls. Use these as sanity checks rather than targets.

SaaS and software, 10–20%. High rates because gross margins are high and there is almost no cost of goods to protect. Deals are complex, cycles run months, and the rep genuinely drives the outcome. Usually tiered on quota attainment, and frequently paid on first-year contract value only.

Real estate, 2.5–3% per side. Low as a percentage because the transaction values are enormous. Three percent of a $400,000 house is more than twenty percent of most software deals. As shown above, the agent keeps well under the headline rate.

Recruitment and staffing, 20–30%. The highest rates anywhere, calculated as a percentage of the placed candidate's first-year salary. The work is finding a scarce person rather than selling a product, placements fall through, and guarantee periods mean a fee can be clawed back if the hire leaves early.

Financial services and insurance, 5–12%.Moderate first-year rates, often paired with a draw and with residual renewals that make year three look nothing like year one. Heavily regulated, so what can be paid and when is frequently constrained by rules rather than negotiation.

Retail, 1–5%. Low because the customer largely arrived intending to buy and margins are thin. Almost always sits on top of an hourly wage or salary rather than replacing it, functioning as a bonus for attachment and upsell rather than as primary pay.

Manufacturing and wholesale, 7–15%. Usually calculated on gross margin rather than revenue, which matters enormously: 10% of the margin on a $100,000 order with a 20% margin is $2,000, not $10,000. Check which base your plan uses before you celebrate.

Common commission mistakes

Confusing markup with margin. They are different numbers and mixing them up will misprice your work. An item that costs $80 and sells for $100 carries a 25% markup ($20 on the $80 cost) but a 20% margin ($20 of the $100 price). Set a commission rate against the wrong one and you will be paying out more than you planned on every single sale.

Forgetting self-employment tax on 1099 income.Commission paid to a contractor arrives with nothing withheld. You owe income tax and self-employment tax, and the self-employment portion covers both halves of Social Security and Medicare because there is no employer paying the other half. Setting aside roughly 25–30% of every payment is the usual rule of thumb, and quarterly estimated payments are typically required rather than optional.

Applying the top tier to everything. The most frequent arithmetic error in tiered plans, and it always errs in the optimistic direction. At $250,000 with an 8% top tier, the wrong method gives $20,000 and the right one gives $16,000. That is a 25% overestimate of your own income, discovered on payday.

Ignoring draw repayment. A recoverable draw already paid to you is money you have spent and will be asked for again. Reps who forget the outstanding balance treat a strong month as a windfall when much of it is settling last month's advance. Track the balance, not just the commission.

Frequently asked questions

How do you calculate sales commission?

Multiply the sales amount by the commission rate. A rep who closes $250,000 at a flat 6% earns $15,000. If the plan is tiered, apply each bracket's rate only to the sales inside that bracket and add the results together.

What is a good commission rate?

It depends on the industry. SaaS and software plans typically run 10-20%, real estate 2.5-3% per agent, recruitment 20-30%, insurance and financial services 5-12%, retail 1-5%, and manufacturing or wholesale 7-15%.

How does tiered commission work?

Tiered (progressive) commission pays a higher rate on each successive bracket of sales, and each rate applies only to the sales inside its bracket. Sales above the top bracket keep earning the top bracket's rate.

What is the difference between a recoverable and a non-recoverable draw?

A recoverable draw is an advance against future commission, so it is repaid out of what you earn. A non-recoverable draw is a guaranteed base you keep regardless of performance, and commission is paid on top of it. The difference decides whether the draw is subtracted from your commission or added to it.

How do commission splits work between reps?

The commission is divided by agreed percentages that total 100%. Splits are normally taken from the net commission, after brokerage fees, fixed deductions, and any draw repayment have been applied.

How do I calculate commission on a team sale?

Work out the total commission on the deal first, subtract any fees or deductions that come off the top, then divide what is left by each person's agreed percentage. Splitting the gross figure instead overstates what everyone actually receives, because the fees still have to come from somewhere.

Is commission income taxable?

Yes. Commission is ordinary income everywhere it is paid. If you are an employee, tax is usually withheld, though commission is often withheld at a flat supplemental rate that may not match your real bracket. If you are self-employed or paid on a 1099, nothing is withheld and you owe both income tax and self-employment tax on the full amount, so setting aside roughly 25-30% of each payment is a common rule of thumb.

Why is my commission lower than the rate I agreed?

Usually a brokerage fee or split, a fixed deduction, or a recoverable draw being repaid out of the current period. Each one comes off the gross commission before you are paid, so a 6% plan can pay out at an effective rate well below 6%.
