How to interpret the result
A commission plan with tiers pays a different rate on different slices of sales, not one flat rate applied to the whole total, so a rep who crosses into a higher tier mid-period earns the higher rate only on the portion above the threshold, the same slice-based logic that applies to progressive tax brackets.
Before you rely on it
What to check
Confirm whether your plan's tiers apply to the whole total once a threshold is crossed, or only to the portion above each threshold. Plans genuinely differ on this, and the difference changes the payout meaningfully.
The common error
Where people go wrong with commission calculator
Assuming crossing into a higher commission tier means the higher rate applies retroactively to the entire period's sales. Most tiered plans apply the higher rate only to the incremental sales above the threshold, not the whole total.

Where the inputs come from
Commissionable sales are the sales that count toward commission, which may exclude returns, taxes, shipping or certain products under your plan. The commission rate is the percentage paid on those sales, and some plans use tiers with higher rates above quotas. Base compensation is fixed salary or draw. Read the commission plan carefully, since definitions of when a sale counts, clawbacks for cancellations and caps vary between employers.
When the result stops applying
Commission plans can include tiers, accelerators, draws against future commissions, caps and clawbacks that this simple calculation does not model. Commission income is taxable and may be withheld at a supplemental rate. Payment timing matters for budgeting. Sales results depend on territory, lead quality and market conditions.
What to compare it with
See the take-home effect on the bonus tax and paycheck calculators, and the annual figure on the take-home pay page. The salary negotiation and job offer comparison calculators compare offers. The payment gross-up calculator turns a desired net into a gross payment.

Frequently asked questions
What is a draw against commission?
An advance paid to a salesperson that is later deducted from earned commission. Some draws are recoverable, meaning you owe the difference if you earn less.
What is a clawback?
A provision that requires you to return commission if the customer cancels or refunds within a set period after the sale.
Is a commission-heavy job riskier?
Yes. Income varies with sales, so plan for lean months and compare the upside with a job that pays a higher salary.
