Enter any two of the three values below — sales price, commission rate, or commission — and the calculator finds the third for a simple percentage commission.
Calculate more complex commission structures, including a base amount, a flat rate, or commission that varies across multiple price tiers.
The commission calculator on this page makes it easy to figure out exactly how much commission a sale earns. Commissions are the backbone of how millions of salespeople are paid, and even small differences in rate or structure can add up to large sums over a year. Whether you are a real estate agent estimating your cut of a home sale, a retail or car salesperson checking your paycheck, a business owner designing a pay plan, or simply curious how a commission works, this tool gives you a fast, accurate answer. The first calculator handles the simple, everyday case — a single percentage of the sale price. The second handles the more complex structures real companies actually use, including a guaranteed base amount and commission rates that change as sales grow.
In sales, a commission is a payment a salesperson earns that is tied directly to how much they sell. It is a powerful incentive: the more you sell, the more you earn. In its simplest form, a commission is a percentage of revenue. If a salesperson earns 3% commission and sells a product for $100, they earn $3 on that sale. Commissions can be the entire paycheck (straight commission) or, more commonly, a bonus layered on top of a base salary or hourly wage. They appear across nearly every industry — real estate, automobiles, insurance, retail, financial services, software, and more — because they align a salesperson's earnings with the company's revenue.
The fundamental commission formula is simple multiplication:
Commission = Sales Price × Commission Rate
For example, on a $200,000 home sale at a 3% commission rate, the commission is $200,000 × 0.03 = $6,000. The simple calculator above lets you solve for any one of the three quantities — sales price, commission rate, or commission — as long as you provide the other two. Enter a price and a rate to find the commission, enter a price and a commission to find the rate that was paid, or enter a rate and a commission to work backward to the sale price. This flexibility is handy for checking a paycheck, reverse-engineering an effective rate, or figuring out how large a sale you would need to hit an earnings target.
Real-world pay plans go well beyond a single flat percentage. Understanding the common structures helps both salespeople evaluating a job offer and managers designing fair, motivating plans.
Under straight commission, the salesperson earns only commission with no base salary. Income is entirely performance-based, offering unlimited upside but no safety net. This model is common in real estate and some high-ticket sales roles, where commissions per sale are large.
The most common structure pairs a guaranteed base salary (or hourly wage) with commission on top. The base provides stability while the commission rewards performance. The tiered calculator above includes a "base commission" option so you can add a fixed amount, or a percentage, on top of the variable portion.
In a tiered plan, the commission rate increases as the salesperson sells more. For instance, a rep might earn 3% on the first $20,000 of sales and 5% on everything above that. Tiered plans strongly motivate salespeople to push past thresholds, because each additional dollar above a tier earns a higher rate. The tiered calculator models exactly this: define each tier's upper limit and its rate, and the tool applies each rate only to the portion of the sale that falls within that tier.
Some companies pay commission on profit or gross margin rather than total revenue, which discourages salespeople from discounting heavily just to close a deal. While this calculator works on sale price, you can use it on a margin figure simply by entering the margin amount as the "sales price."
A draw is an advance against future commissions, giving the salesperson predictable income during slow periods that is later recovered from earned commissions. It is essentially a loan structured around the commission plan.
The tiered calculator builds a commission from up to three parts. First, an optional base commission can be added as either a flat dollar amount or a percentage of the sale price. Second, you choose whether the commission varies with price. If it does not, you simply enter a single rate (as a percentage or a flat dollar amount) that applies to the whole sale. If it does vary, you define a series of tiers.
Each tier has a "From" and a "To" boundary and a rate. The "From" value of each tier is automatically set to the "To" value of the previous tier, and the first tier always starts at $0. Leave the final tier's "To" value blank to indicate it has no upper limit. The calculator then applies each tier's rate only to the portion of the sale that falls inside that tier — this is called a marginal or graduated structure. For example, with tiers of 3% up to $20,000 and 5% above $20,000, a $200,000 sale earns 3% on the first $20,000 ($600) plus 5% on the remaining $180,000 ($9,000), for a total of $9,600. Add a $1,000 base and the total becomes $10,600.
Real estate: A home sells for $400,000 with a 6% total commission, typically split between the buyer's and seller's agents. The total commission is $24,000; each side's brokerage receives $12,000, which is then split again between the brokerage and the agent. Using the simple calculator with a price of $400,000 and a rate of 6% gives the $24,000 total instantly.
Car sales: A salesperson earns 25% of the dealership's gross profit on a vehicle. If the gross profit on a car is $2,000, the commission is $500. Entering $2,000 as the price and 25% as the rate confirms this.
Tiered software sales: A rep earns 8% on the first $50,000 of quarterly sales, 10% from $50,000 to $150,000, and 12% above $150,000. On $200,000 of sales, the commission is 8% × $50,000 ($4,000) + 10% × $100,000 ($10,000) + 12% × $50,000 ($6,000) = $20,000. The tiered calculator computes this with three tiers.
Commission income is taxable. In the United States, the IRS treats commissions as "supplemental wages," and employers often withhold federal income tax on them at a flat supplemental rate, separate from regular wage withholding. Commissions are also subject to Social Security and Medicare taxes. Because withholding on commissions can differ from withholding on salary, your actual tax liability may be higher or lower than what is withheld, so it is wise to plan for this difference. Self-employed salespeople and independent contractors who earn commissions must handle their own estimated taxes, including self-employment tax. This calculator computes gross commission before any taxes or deductions.
Commission-based pay is woven into the fabric of many industries, each with its own conventions. In real estate, agents typically earn a percentage of the sale price, split among brokerages and the agents on each side of the transaction. In automotive sales, commission is often a share of the dealership's gross profit on each vehicle rather than the sticker price, which is why negotiating hard can affect a salesperson's pay. Insurance agents earn commission on premiums, frequently with a larger first-year commission and smaller renewal commissions in later years. Retail roles, especially in furniture, electronics, and jewelry, commonly pay a modest base plus a percentage of sales. In financial services, advisors and brokers may earn commission on products sold or assets managed. And in technology and software sales, reps often work under tiered plans with quotas and accelerators that pay sharply higher rates once targets are exceeded. Across all of these, the core math is the same, which is why a single commission calculator can serve such different fields.
Doing commission math by hand is error-prone, especially with tiered structures where each portion of a sale earns a different rate. A calculator removes the guesswork and lets you answer practical questions instantly: How much will this deal pay me? What rate did I actually earn on last month's sales? How much more would I make if I crossed into the next tier? For managers, it makes it easy to model how a proposed plan would pay out across a range of sales figures before rolling it out to the team. Because the calculator shows the breakdown tier by tier, it also doubles as a transparency tool, helping everyone understand exactly how a final commission figure was reached.
Multiply the sale price by the commission rate expressed as a decimal. For a 5% commission on a $10,000 sale, multiply $10,000 by 0.05 to get $500. The simple calculator above does this instantly and can also work backward to find the rate or the sale price if you know the commission.
A tiered commission pays different rates on different portions of a sale or of total sales. For example, 3% might apply to the first $20,000 and 5% to everything above it. Only the portion of the sale within each tier earns that tier's rate, which rewards salespeople for reaching higher levels. The tiered calculator handles up to several tiers automatically.
With straight commission, all income comes from commission and there is no guaranteed pay. With base salary plus commission, the salesperson receives a fixed salary plus commission on top, trading some upside for stability. The tiered calculator's "base commission" option lets you model a guaranteed amount added to the variable portion.
In the United States, total real estate commissions have traditionally been around 5% to 6% of the sale price, split between the buyer's and seller's agents and then again with their brokerages. Rates are negotiable and have been changing, so always confirm the specific rate in your agreement. Use the simple calculator to see the dollar amount for any price and rate.
It depends on the company's plan. Many pay commission on total revenue (the sale price), while others pay on gross margin or profit to discourage excessive discounting. This calculator works with whatever figure you enter as the sales price, so you can use it for either approach.
Commissions are fully taxable and, in the US, are often classified as supplemental wages, which employers may withhold at a flat federal rate. They are also subject to Social Security and Medicare taxes. The withholding can differ from your regular paycheck, so your final tax owed may not match what was withheld. This calculator shows gross commission before taxes.
