Commission Types
Percentage Commission
Commission = Sale Amount × (Commission Rate / 100)
Example: $10,000 × 5% = $500 commission
Fixed Commission
Fixed amount regardless of sale value
Example: $500 per sale
Commission Calculator
This commission calculator turns a sales figure and a rate into exact variable pay: $50,000 in sales at an 8% rate earns $4,000. It handles flat-rate plans in one step and tiered plans bracket by bracket, so both salespeople forecasting their pay cheque and managers designing compensation plans can model outcomes before the quarter starts.
Key facts
- $50,000 in sales at an 8% flat rate pays $4,000; at 10% it pays $5,000.
- Tiered example: 5% to $50,000 then 8% above means an $80,000 quarter pays $4,900 — $1,500 less than applying 8% to everything.
- In the US, commissions paid separately from wages are withheld federally at a flat 22% on supplemental wages up to $1 million per year.
What is the Commission Calculator?
A sales commission is variable compensation paid as a percentage of the sales a person generates, on top of (or instead of) base salary. Plans come in three broad shapes: flat rate, where every dollar of sales pays the same percentage; tiered, where the rate steps up as cumulative sales cross thresholds; and profit-based, where the percentage applies to gross margin rather than revenue. The structure chosen changes incentives — tiered plans reward pushing past quota, while margin-based plans discourage heavy discounting.
How does the Commission Calculator work?
For a flat plan the math is a single multiplication: Commission = Sales × Rate, so $80,000 × 5% = $4,000. Tiered plans apply each rate only to the slice of sales inside its bracket, exactly like income-tax brackets. Under a plan paying 5% up to $50,000 and 8% above, an $80,000 quarter earns $50,000 × 5% + $30,000 × 8% = $2,500 + $2,400 = $4,900 — not $80,000 × 8%, a common misreading that overstates the payout by $1,500.
What is the Commission Calculator formula?
- Sales – revenue or units
- Rate% – plan-specific

Frequently asked questions
Multiply the sales amount by the commission rate as a decimal: Commission = Sales × Rate. A salesperson closing $50,000 at an 8% rate earns $50,000 × 0.08 = $4,000. If the plan is tiered, split the sales into brackets first and apply each bracket its own rate before summing the pieces.
Most sales commission rates fall between 5% and 10% of revenue, though the spread across industries is wide. Real-estate commissions in the US have traditionally totalled around 5–6% of the sale price split between agents, while SaaS sales roles commonly pay about 10% of contract value. Rates on gross margin plans run higher than revenue-based rates because the base is smaller.
A tiered plan pays progressively higher rates as sales cross set thresholds, with each rate applying only to the sales inside its own bracket. Under 5% up to $50,000 and 8% beyond, an $80,000 performance pays $2,500 on the first bracket plus $2,400 on the remaining $30,000 — $4,900 total. Some aggressive plans are retroactive instead, applying the top rate to all sales once a threshold is hit.
Most plans pay commission on revenue because it is simple and visible to the rep, but a significant minority pay on gross profit to protect margins. On a $50,000 deal carrying a 40% gross margin, a 10% revenue commission pays $5,000 while a 20% margin commission pays $4,000 — and the margin plan pays nothing extra for discount-driven volume. Margin-based plans align sellers with profitability at the cost of transparency.
Commission is taxed as ordinary employment income, but withholding often differs from salary. In the United States, commissions paid separately from regular wages are treated as supplemental wages and typically withheld at a flat 22% federal rate on amounts up to $1 million per year. The final tax owed is settled at your marginal rate when you file, so the flat withholding is a timing difference, not a separate tax.
A draw is an advance against future commissions that guarantees a minimum pay cheque during slow periods. With a $3,000 monthly recoverable draw, a rep who earns only $2,000 in commission still receives $3,000, and the $1,000 shortfall is deducted from future commission. A non-recoverable draw waives the clawback, functioning as a temporary salary floor — common during ramp-up for new hires.
