How does the Commission Calculator work?
The calculator multiplies commissionable sales by the commission rate. If base pay is entered, it adds the commission to base pay to estimate combined compensation for the period.
For revenue profitability after business costs rather than employee compensation, use the Profit Margin Calculator.
What commission plans are not modeled?
This tool models one flat percentage. Real plans may use tiers, quotas, accelerators, caps, clawbacks, bonuses, split credit, product-specific rates or payment timing rules. Use the actual compensation plan for payroll decisions.
When a sale price is being set from cost, the Markup Calculator addresses pricing rather than compensation.
How should commissionable sales be entered?
Enter only the sales amount that the plan defines as commissionable for the period. Gross bookings, collected revenue and recognized revenue are not always treated the same by a compensation plan.
The Sales Tax Calculator can separate customer sales tax from a pre-tax transaction amount when that distinction is relevant.
What should employers and workers verify?
Commission agreements, wage laws, payroll tax withholding and timing rules can affect actual pay. For broader business inflow and outflow planning, use the Cash Flow Calculator.
