Commission Calculator

Calculate sales commission and total earnings

This commission calculator supports four common compensation questions. Use flat-rate mode for one commission percentage, tiered mode for progressive or retroactive brackets, rate mode to find the effective commission percentage from sales and commission, or split mode to divide a gross commission after referral deductions and fees. Currency selection changes display formatting only; it does not convert currencies.

Flat-rate commission formula

A flat commission applies one percentage to the full commissionable sales or revenue amount. Add base pay and bonuses to find gross period earnings, then subtract any entered deductions for a simple net estimate.

commission = sales x commission rate
gross earnings = base pay + commission + bonus
estimated net = gross earnings - entered deductions

For example, $50,000 of commissionable sales at 5% produces $2,500 of commission. With $2,000 of base pay and no bonus, gross earnings for the period are $4,500.

Tiered commission calculator

Tiered plans reward different portions of sales at different rates. This page supports two methods because compensation plans use the word “tiered” differently.

Progressive or marginal tiers apply each rate only to sales inside that band. With the defaults, the first $10,000 earns 5%, sales from $10,000 to $25,000 earn 7%, and sales above $25,000 earn 10%.

progressive commission = tier 1 sales x rate 1 + tier 2 sales x rate 2 + tier 3 sales x rate 3

Retroactive tiers apply the single highest reached rate to all commissionable sales. If $50,000 reaches the 10% tier, the entire $50,000 receives 10% in this mode. Always check the written plan because the two methods produce materially different payouts.

Find the commission rate

When sales and commission are known, effective commission rate equals commission divided by sales. A $2,500 commission on $50,000 of sales equals 5%.

commission rate = commission earned / commissionable sales x 100

This effective rate can help audit a statement, but it does not prove that payroll applied every quota, accelerator, cap, draw, return, or product-specific rule correctly.

Split commission

Split mode first calculates a gross commission pool from transaction value and gross rate. It then subtracts the entered referral percentage, applies your share to the remaining pool, and subtracts fixed fees.

gross commission pool = transaction value x gross rate
after referral = gross pool x (1 - referral rate)
your commission = after referral x your share - fees

For a $500,000 transaction with a 3% gross commission, the pool is $15,000. A 70% share with no referral deduction or fees produces $10,500. This is arithmetic only; contracts, brokerage policies, team agreements, transaction sides, and local practices determine which inputs apply.

Commissionable sales are not always gross sales

A plan may exclude taxes, shipping, discounts, returns, canceled orders, uncollected invoices, low-margin products, or certain accounts. Some plans calculate commission on gross revenue, net revenue, gross profit, units, contracts, or another credited measure. Enter the amount defined as commissionable by the actual plan.

Base pay, bonuses, draws, and deductions

Base pay is fixed compensation for the selected period. A bonus is separate additional compensation entered here as a fixed amount. Deductions can be used for a known charge, draw recovery, fee, or rough withholding estimate, but the calculator does not determine payroll taxes. A recoverable draw can create a balance against future commission; that requires period-by-period accounting beyond this single-period estimate.

Commission pay and US wage rules

The US Department of Labor describes a sales commission as money paid after completing a task, usually selling a certain amount of goods or services. The Fair Labor Standards Act does not itself require employers to pay commissions, but wage, minimum-wage, overtime, recordkeeping, state-law, and contract rules may still apply. Commission arrangements should be documented and reviewed under the law that governs the worker and employer.

For some retail or service employees, a specific overtime exemption may depend on compensation and regular-rate conditions. The Department of Labor's Fact Sheet #20 explains the federal Section 7(i) framework. This calculator does not decide employee classification, exemption eligibility, regular rate, minimum wage, or overtime.

Commission withholding is not final tax

IRS Publication 15 for 2026 lists commissions among supplemental wages and explains more than one withholding method depending on how supplemental wages are paid and identified. Withholding shown on a paycheck is a prepayment toward tax, not necessarily the final tax attributable to the commission. This calculator deliberately uses a user-entered dollar deduction instead of applying one tax percentage to everyone.

Audit a commission statement

Confirm the credited sales period, commissionable base, returns and clawbacks, quota attainment, tier method, rate, accelerators, caps, split order, referral deductions, fees, base pay, and prior draws. Calculate each component separately and compare the result with the statement. Keep the plan document and transaction-level records when a discrepancy needs review.

Frequently asked questions

What is a good commission rate?

There is no universal rate. It depends on industry, margin, sales cycle, role, territory, base pay, quota, risk allocation, and the written compensation plan.

Does tiered commission apply the top rate to all sales?

Sometimes. Choose progressive mode when each band is paid separately, or retroactive mode when the highest reached rate applies to all sales.

Are commissions taxed differently?

Payroll withholding procedures can differ for supplemental wages, but withholding is not the same as final tax liability. Consult current IRS guidance and a qualified tax professional for your situation.

Can I calculate a commission split?

Yes. Enter the transaction value, gross commission rate, referral percentage, your percentage share, and fixed fees.
