Commission Calculator
Commission plans are quoted in percentages but lived in dollars: 8% of $45,000 on top of a $2,000 base is $5,600 — and whether that's a good month depends entirely on where the quota sits. Enter base, rate, revenue and an optional quota; the calculator returns the total, the commission share of pay, and your attainment percentage in one line.
The note line does the part sales reps actually need mid-month: how many dollars of revenue stand between you and quota, and what each additional 10% of revenue is worth at your current rate. Inputs are remembered on this device, so updating after every closed deal takes seconds — and the share button packages the math for the manager conversation.
How to use
- Enter your base pay per period, commission rate and revenue booked — the total updates live.
- Add your quota to see attainment percentage and the dollar gap to 100%.
- Share the paycheck math with one tap, or bookmark it — your plan numbers are remembered.
Frequently asked questions
How is commission calculated?
Commission = revenue × rate. A $45,000 month at 8% earns $3,600, which stacks on your base: $2,000 + $3,600 = $5,600 total. The calculator keeps base and commission separate so you always see which half is doing the work.
How much of my pay should be commission?
Common splits run 50/50 to 60/40 (base/commission) in B2B sales and 30/70 or higher in transactional roles. The commission-share stat shows your actual mix — the number to compare against your plan's target and against what you can stomach in a slow month.
What does quota attainment mean for pay?
Quota is the revenue floor your plan expects; attainment is revenue ÷ quota. Many plans add accelerators — a higher rate past 100% — so crossing the line can raise the rate on every additional dollar. The attainment stat keeps that checkpoint visible all month.
Do commissions get taxed differently?
No — commission is ordinary supplemental wage income and is taxed as it's paid, often at flat withholding rates that trues up at filing. The calculator shows gross pay; your actual take-home depends on your withholding elections.
