Commission calculator: what sales reps and real estate agents take home
Sales commission equals sale amount multiplied by commission rate. A $200,000 home sold at a 6% rate generates $12,000 of gross commission, which a real estate brokerage typically splits with the agent and with the buyer side. The calculator above handles three of the most common structures: basic flat-rate commission, an agent-broker split, and a base salary topped up with commission. The Bureau of Labor Statistics tracks more than 1.8 million wholesale and manufacturing sales reps in the United States, with median total pay around $69,000 in 2024, and most of that income depends on the formulas explained here.
Commission turns a salary line into a variable expense for the company and a variable income for the rep. That alignment is the point: when the rep sells more, the rep earns more, and the company pays more only because revenue rose to match. The trick is structuring the percent, the threshold, and the split so both sides keep working.
What is sales commission?
Commission is supplemental compensation tied directly to closed sales. The U.S. Department of Labor defines it as pay calculated as a percent of the sales a worker completes, in addition to or instead of a base wage. The Fair Labor Standards Act covers commission earners under specific rules: outside sales reps are exempt from overtime, inside sales reps under FLSA Section 7(i) can be exempt if more than half their pay is commission and they earn at least 1.5 times minimum wage.
Plain commission only pays when something closes. Base plus commission guarantees a floor and adds variable upside. Draw against commission advances cash that gets reconciled against earned commission later. Each pattern moves the risk and reward between employer and employee in a different way.
The Bureau of Labor Statistics reports that real estate brokers earn a median annual wage of about $63,000, while sales agents earn around $56,000. Both figures vary widely by metro: top quartile agents in California and the New York metro area regularly clear six figures, while the bottom quartile nationwide earns under $35,000. Commission income is famously bimodal.
The commission formula, three ways
The basic commission identity is straightforward arithmetic. The complications come from layering splits, bases, and tiers on top.
Commission = Sale × Rate ÷ 100Agent share = Commission × Split ÷ 100Total pay = Base + CommissionThe first form gives gross commission. The second carves out the agent share when a brokerage takes a cut. The third stacks a guaranteed base on top of variable commission. Plug any sale, rate, split, or base into the calculator above to see all three breakdowns at once.
Real estate commission splits explained
Residential real estate commission in the United States traditionally runs 5 to 6% of the sale price. That total is split first between the two brokerages on the transaction, then again between each brokerage and its agent. A $400,000 home at 5.5% generates $22,000 of gross commission. Split equally, each side receives $11,000. If the listing agent has a 70/30 deal with their brokerage, the agent receives $7,700 and the brokerage keeps $3,300.
The August 2024 settlement between the National Association of Realtors and home-seller plaintiffs changed how buyer-side commission gets advertised. Buyer commissions are no longer published on the MLS, and buyers now sign explicit written agreements with their agents specifying the rate. The math has not changed, but the negotiation is more visible.
Commission rates by industry
Commission rates vary wildly by industry, deal size, and gross margin. The pattern is roughly inverse: high-volume, low-margin categories pay small percentages, and high-touch, low-volume sales pay much higher rates.
- Auto dealers = 20 to 30% of gross profit per unit, not gross price
- Insurance, new life policies = 40 to 100% of first-year premium, then 2 to 5% on renewals
- B2B SaaS = 7 to 15% of annual contract value, with accelerators above quota
- Wholesale manufacturing rep = 5 to 15% on flat or tiered structures
- Financial advisor on mutual funds = 1 to 6% load, or annual trail commission
- Retail electronics = 1 to 5% on hourly base + commission structures
Base salary plus commission structures
Base plus commission is the most common compensation pattern in B2B sales. A typical SaaS account executive earns a base salary of $60,000 to $90,000 with on-target earnings of $120,000 to $180,000, meaning roughly half of total pay is variable. The base covers the ramp-up period when a new rep has no pipeline; the commission rewards everything beyond that.
When comparing job offers, compute the percent of total comp that comes from base vs. commission. A high-base, low-commission role is lower risk but capped. A high-commission role is uncapped on the upside but exposes you to bad territories and slow quarters.
Tiered commission and accelerators
Tiered commission pays different rates at different sales volumes. A rep might earn 5% on the first $50,000 of monthly sales, 8% between $50,000 and $150,000, and 12% on everything above $150,000. The marginal rates apply only to dollars within each tier, not the whole amount. Sales reps unfamiliar with marginal-rate logic often miscalculate their own pay by applying the top tier to total sales.
Accelerators are an aggressive variant: above 100% of quota, the commission rate doubles or even triples. A 10% base rate with a 2x accelerator above quota becomes 20% on every dollar over target. Accelerators concentrate reward on overperformers, which is exactly what most sales organizations want.
Commission clawbacks and draws
If a customer cancels, refunds, or charges back, most commission contracts trigger a clawback: previously paid commission is recovered from future cheques. SaaS contracts typically have 90-day to 12-month clawback windows. Insurance clawbacks can extend through the full chargeback period on the policy.
A 24-month SaaS clawback means commission paid on a $100,000 contract that cancels at month 18 is fully recoverable. If you spent that commission, the company will deduct it from your next paycheques. Treat large commission cheques as partially escrowed until the clawback window passes.
Common commission mistakes
Errors cluster around timing, returns, and split arithmetic. The most common: paying commission on gross revenue when the contract says net of returns, confusing markup commission with margin commission, applying a tiered rate to the whole sale instead of the marginal tier, and forgetting that draws are recoverable. Round only at the end, not at each stage. And if your structure includes a split and a base, run both formulas separately before adding them — combining them in one head-math step is where six-figure errors slip through.
