Commission Calculator
Calculate sales commission, total earnings, and target sales.
Calculate percentage-based sales commission, combine it with optional base pay, and estimate the sales amount required to earn a target commission at the same rate.

At a 5% commission rate.
This calculator models a single flat percentage rate. Real compensation plans may use quotas, tiers, accelerators, caps, draws, splits, returns, taxes, eligibility rules, or different definitions of commissionable sales.
About This Tool
Use this calculator for straightforward commission plans where commission is a fixed percentage of commissionable sales. It calculates commission earned, optionally adds base pay to show combined earnings, and can reverse the formula to estimate the sales amount required for a target commission. It deliberately does not guess how a particular employer defines eligible sales or handles quotas, tiers, returns, taxes, or other compensation rules.
How To Use It
- Enter the sales amount that is commissionable under the plan you are modeling.
- Enter the flat commission rate as a percentage, such as 5 for 5%.
- Optionally enter base pay for the same pay period if you want to see base pay plus calculated commission.
- Optionally enter a target commission to solve the sales amount required at the entered rate.
- Compare the result with the actual compensation plan before using it for payroll, budgeting, or performance decisions.
Examples
5% commission on 10,000
At a 5% flat rate, 10,000 of commissionable sales produces 500 of commission because 10,000 × 5 ÷ 100 = 500.
Commission plus base pay
If commissionable sales are 25,000 at 4%, commission is 1,000. Adding 1,200 of base pay for the same period gives modeled total earnings of 2,200.
Sales needed for a target
To earn 750 of commission at a 5% flat rate, required commissionable sales are 750 ÷ 0.05 = 15,000.
Zero sales
With zero commissionable sales, percentage commission is zero regardless of a non-negative rate. Base pay, if entered, can still make total modeled earnings positive.
Useful Notes
Commission formula
For a flat percentage plan, commission = commissionable sales × commission rate ÷ 100. Total modeled earnings = base pay + commission. The calculator keeps the numbers currency-neutral, so all money inputs should use the same currency and pay period.
Reverse calculation for target commission
Required sales = target commission × 100 ÷ commission rate. A positive commission rate is required for this reverse calculation because division by a zero rate is undefined. This result assumes every unit of the entered sales amount earns the same flat rate.
Commissionable sales matter
A contract may calculate commission from booked revenue, collected revenue, gross profit, units, recurring revenue, or another defined base. Refunds, cancellations, discounts, taxes, shipping, territories, account ownership, and split credit may also affect what counts. Enter the amount that matches the plan rather than assuming all revenue is commissionable.
Flat rates versus tiers and accelerators
This tool models one flat rate across the full sales amount. Tiered plans may apply different rates to different bands or increase the rate only after a quota is reached. Accelerators, decelerators, caps, floors, draws, bonuses, and clawbacks require plan-specific calculations and are not inferred here.
Use results as an arithmetic check
The result is useful for examples, scenario planning, and checking simple percentage calculations. It is not a payroll statement, contract interpretation, tax calculation, or guarantee of compensation. Actual earnings are governed by the applicable compensation plan and payroll rules.
FAQ
How do I calculate a 5% commission?
Multiply commissionable sales by 0.05. For example, 8,000 × 0.05 = 400. In this calculator, enter 8,000 as sales and 5 as the commission rate.
Does base salary affect the commission percentage?
Not in this flat-rate model. Commission is calculated from sales and the rate, then optional base pay is added separately to show combined modeled earnings.
Can I calculate how much I need to sell for a commission goal?
Yes. Enter a positive commission rate and a target commission. The calculator divides the target by the decimal commission rate to estimate required commissionable sales.
Does this calculator support tiered commission?
No. It intentionally models a single flat percentage. A tiered or quota-based plan can produce different results depending on whether rates apply marginally, retroactively, or under other plan-specific rules.
Are taxes deducted from the result?
No. The result is a gross arithmetic model using the values entered. It does not calculate withholding, payroll taxes, deductions, benefits, currency conversion, or jurisdiction-specific rules.
