For a flat plan, commission equals the sale amount multiplied by the commission rate.
TL;DR: Use the commission calculator to handle flat, tiered, and base-plus plans. A $2,000 sale at 15% pays $300.
Flat commission
The simplest case is one rate on the whole sale. A $2,000 sale at a 15% rate pays $2,000 × 0.15 = $300. If you want to work backward from a known payout, divide the commission by the rate. A $300 commission at 15% means a $2,000 sale.
Tiered, base, and draw plans
Tiered plans split sales into bands, and each band has its own rate. Say you sold $27,000 across three marginal tiers: 3% on the first $10,000, 5% on the next $10,000, and 10% on the rest. The first band pays $300, the second pays $500, and the last $7,000 at 10% pays $700. Add them up and you earn $1,050. Only the dollars inside each band get that band’s rate.
Base plus commission adds a fixed salary to your commission. If your base is $1,000 for the period and you earned $1,050 in commission, your total is $2,050.
A draw against commission is an advance. The company pays you, say, $1,500 up front, then subtracts it from your earned commission. With $1,050 earned against a $1,500 recoverable draw, you carry a $450 shortfall into the next period.
Plug your own bands and rates into the commission calculator to see the full payout in one pass.
