Commission Calculator
Commission pay, total earnings, and per thousand rate from sales, rate, and base salary.
What it does
Sales commission pays a slice of each deal: volume times rate, plus any base salary for the period. Straight commission lives or dies by the pipeline, while base plus commission trades ceiling for a floor.
The tool above takes sales volume with rate and base pay. It returns commission dollars with total pay and the earnings per $1,000 sold beside them.
The default of $50,000 at 8% with a $3,000 base pays $4,000.00 commission for $7,000.00 total, or $80.00 per $1,000 sold. A pure $20,000 book at 10% with no base pays $2,000.00 flat.
The tax handling follows IRS supplemental wage rules with national compensation survey data matching the pay definitions. Both treat commissions as wages, often withheld at the 22% flat supplemental rate.
How to use
- Enter closed sales volume for the period.
- Enter the commission rate as a percent.
- Enter base salary for the period, 0 if none.
- Read commission first for the variable slice.
- Read total pay for the paycheck figure.
Formula
- sales
- Closed volume in the period.
- rate
- Percent slice of each sale.
- base
- Fixed pay under the variable slice.
Flat rate math throughout. Tiered plans that raise the rate past quotas need each tier run separately, then summed. Clawbacks on refunded deals subtract the same way.
Worked example
Example: $50,000 at 8% with $3,000 base
Defaults: sales 50000, rate 8%, base 3000.
- Commission: 50,000 x 8 / 100 = $4,000.00.
- Total: 3,000 + 4,000 = $7,000.00.
- Per thousand: 8 x 10 = $80.00 per $1,000 sold.
- Withholding hint: 4,000 x 22% = $880.00 often held as supplemental wages.
- Tool shows $4,000.00, $7,000.00, $80.00 per $1,000 sold.
Reference table
| Plan | Commission | Total |
|---|---|---|
| 8% with $3,000 base | $4,000.00 | $7,000.00 |
| 10% with no base | $5,000.00 | $5,000.00 |
| 5% with $4,000 base | $2,500.00 | $6,500.00 |
Limits
- Flat rate only; tiers and accelerators need split math.
- Refunds and clawbacks excluded until booked.
- Draws against commission reshape timing, not totals.
- Taxes excluded from the headline figures.
Common mistakes
- Applying the rate to pipeline instead of closed sales.
- Forgetting the base when comparing two offers.
- Quoting gross commission as take home past withholding.
- Missing quota thresholds that change the rate.
- Ignoring clawback terms on cancellations.

Questions
How is commission calculated?
Sales times rate over 100, plus base. $50,000 at 8% is $4,000.
Base plus commission or straight?
Base pays a floor with a lower rate; straight pays only rate, usually higher.
Are commissions taxed more?
Withholding often runs 22% flat as supplemental wages; the final tax follows the yearly bracket.
What is a good commission rate?
Varies by industry: low single digits for big ticket, double digits for high margin services.
Do refunds cut commission?
Usually yes through clawbacks: the same rate times the refunded sale comes back off.
What are tiered commissions?
Rates that rise past quota steps. Run each tier separately and add them.
