Commission Calculator – Pay from Sales & Rates

This commission calculator works out commission pay from sales and your rate — flat, tiered, or graduated — plus your total pay with base salary.

Commission = Sales × Rate — With Tiers Done Properly

Flat plans are one multiplication. Tiered/graduated plans are two: base rate up to the threshold, accelerator rate only on the excess — misapplying the top rate to all sales is the classic self-inflicted payroll error (in both directions).

Worked Examples (Verified)

• $50,000 sales at flat 8% (defaults): $4,000 commission — the baseline every tier is compared against
• Tiered version (8% to $40k, 12% above): 3,200 + 1,200 = $4,400, effective rate 8.80% — the accelerator paid $400 extra on the last $10k of effort: the incentive, quantified
• The retroactive trap: a plan paying 12% on ALL sales once $40k is crossed would pay $6,000 on the same $50k — and $4,799 at $39,999 of sales: a $1,200 cliff riding on one dollar (know which structure you signed)
• Real-estate flavor: 3% per side on a $450,000 sale = $13,500 before brokerage splits (a 70/30 split leaves $9,450) — run splits as sequential percentages here

Plan-Reading Checklist

• Commissionable basis: gross sales, net of returns, collected revenue, or margin? The basis moves pay more than the rate.
• Timing: booked vs paid vs delivered — and what clawbacks apply on cancellations, and for how long.
• Draws are loans against future commission (recoverable or not) — they’re not salary; treat the reconciliation statement as a bill.
• Caps and decelerators exist in some plans (rate drops past a ceiling) — tiered mode here models accelerators; a cap is the same math with the inequality flipped.

Frequently Asked Questions

How do you calculate commission?

Sales × rate: $50,000 at 8% = $4,000. For tiered plans, apply each rate to its band: 8% on the first $40,000 ($3,200) plus 12% on the $10,000 above ($1,200) = $4,400, an 8.8% effective rate. This calculator handles both structures plus base salary totals.

What’s a typical commission rate?

It varies enormously by industry and margin: retail often 1–10% (sometimes per-item), SaaS sales commonly 8–15% of first-year contract value against quota, real estate around 2.5–3% per side of a transaction, insurance renewals low-single-digits. The right benchmark is your own plan document and peers in the same seat.

Tiered vs retroactive commission — what’s the difference?

Tiered (graduated): the higher rate applies only to sales above the threshold. Retroactive: crossing the threshold re-rates all sales at the higher rate, creating a cliff at the boundary. On $50,000 with a $40,000 threshold (8%→12%): tiered pays $4,400, retroactive pays $6,000. Confuse them and forecasts go wrong in the expensive direction.

What is a draw against commission?

An advance paid before commissions are earned, then deducted from them (recoverable draw) — or not deducted (non-recoverable, effectively a salary floor). Recoverable draws are debt: a bad quarter can leave you owing the house, which is why the reconciliation matters more than the headline rate.

Is commission taxed differently?

In the US, commissions are ordinary income, commonly withheld at the flat supplemental rate (22% federal) when paid separately — which often over- or under-withholds versus your actual bracket; the annual return trues it up. It’s pay, just variable — budget it like the Overtime Calculator treats overtime: on the base, not the bonus.
