How to use the commission calculator
Enter the sales amount credited under your plan, the commission percentage, and any base pay for the same period. The calculator multiplies sales by the commission rate, then adds base pay.
Commission formula
Real commission plans can include tiers, quotas, draws, caps, accelerators, product-specific rates, clawbacks, or delayed crediting. This tool models one flat rate.
Example: Sam combines commission and base pay
Sam earns 5% on $20,000 of eligible sales during a month, giving $1,000 in commission. With $2,000 of base pay for the same month, total gross pay is $3,000.
A tiered plan or a plan based on gross profit needs a separate calculation for each tier or the correct commission base. Returns and clawbacks are not automatically deducted.
Use sales and base pay from the same period
A 5% commission on $10,000 of credited sales is $500. Adding $2,000 of base pay for that period gives $2,500 of gross pay.
For tiered rates, calculate each sales band separately and add the commissions. Do not apply the highest rate to all sales unless your plan does so.
Assumptions and limitations
What the estimate assumes
Tiered or quota-based commission plans are not modeled automatically.
Commission Calculator FAQs
How do I calculate a 5% commission?
Multiply the credited sales amount by 0.05. For example, 5% of $10,000 is $500.
Does this include taxes?
No. The result is gross commission and gross combined pay.
Can I include base salary or hourly pay?
You can enter a base-pay amount for the same period, but the calculator does not convert between payroll periods automatically.
What if my commission rate changes after a quota?
Run each tier separately or use the rate that applies to the sales segment you are checking.
Use your actual compensation plan for payroll decisions. This calculator models a single flat commission rate.
