How to Calculate Commission: Straight, Tiered and Draw Plans With Worked Examples

Commission looks simple — a percentage of what you sold — right up until the statement arrives and the number is smaller than the one in your head. Almost every dispute traces back to one of three things: a tier applied to the wrong slice of sales, a draw quietly recovered, or an effective rate nobody bothered to compute. This guide explains how to calculate commission on straight and tiered plans, works a full month in numbers, and shows the reverse calculation — how much you must sell to hit a target payout — using our commission calculator to check each step.

How to Calculate Commission, Step by Step

1. Find your plan type in writing. Straight rate, tiered, or tiered with a draw — the math is completely different for each, and the only version that counts is the one in your signed comp plan. 2. For a straight plan, multiply. Commission = total sales × rate. That is the whole formula. 3. For a tiered plan, slice the sales into bands. Apply each band’s rate only to the sales inside that band, exactly like income tax brackets, then add the bands together. 4. Subtract any recoverable draw. If the company advanced you money against this commission, it comes off the top of the payout. 5. Compute your effective rate. Total commission ÷ total sales — the one honest number for comparing two plans. The calculator runs straight or tiered mode with up to three bands and shows the per-tier breakdown and the effective rate as you type.

The Three Plan Shapes: Straight, Tiered and Draw

A straight plan pays one rate on everything: predictable, transparent, and common in retail and real estate. A tiered plan pays more as you sell more — the rate steps up at sales thresholds — which is why SaaS and B2B teams favor it: it keeps the incentive alive after quota. A draw is not a rate at all but a payment mechanism bolted onto either shape: the company advances a fixed amount each period, then recovers it from commissions as they land. Recoverable draws carry any shortfall forward; non-recoverable draws are a guaranteed floor. The plan detail that matters most in April is which kind of draw you signed in January.

Worked Example: $42,000 in Sales on a 4%/6% Tiered Plan

A rep closes $42,000 in a month. Her plan pays 4% on the first $15,000 and 6% on everything above it. Tier 1: $15,000 × 4% = $600. Tier 2: the sales above the threshold are $42,000 − $15,000 = $27,000, and $27,000 × 6% = $1,620. Total commission: $600 + $1,620 = $2,220. Effective rate: $2,220 ÷ $42,000 = 5.29% — between her two tier rates, as it always is on a graduated plan. Had she (wrongly) applied 6% to the full $42,000 she would have expected $2,520, and had the plan been a straight 5% she would have earned $2,100. The tiered plan beats the flat one at her volume — but at $12,000 in sales it would pay just $480 against the flat plan’s $600. Tiered plans reward big months and punish small ones; the effective rate is how you see it.

Working Backwards: How Much Must You Sell?

Targets are usually set in dollars of commission, not dollars of sales, so run the math in reverse. On a straight plan it is one division: to earn $3,000 at 6%, you need $3,000 ÷ 0.06 = $50,000 in sales. On a tiered plan, fill each band from the bottom: a $2,500 target on a plan paying 5% up to $10,000 and 10% above it needs the first band maxed ($10,000 × 5% = $500 of the target), leaving $2,000 to earn at 10% — another $20,000 in sales, $30,000 total. Knowing the sales number behind the commission number is what turns a quota conversation from vibes into a plan — and our break-even calculator does the same job for the business’s side of the table.

Commission and Overtime: The Overlap Almost Nobody Checks

If you are a non-exempt employee — paid hourly, or salaried but failing the exemption tests — your commissions feed into your overtime math. Under the FLSA, non-discretionary commissions are part of your regular rate, so the 1.5× premium is owed on a rate that includes them, typically by spreading the commission across the workweeks in the period it was earned and topping up the premium. Employers miss this constantly, and it is one of the most common findings in wage audits. Our overtime pay calculator explains the regular-rate rule in full.

Common Mistakes

Applying the top tier rate to all sales. Tiers are bands, not switches: the higher rate touches only the sales above the threshold. This one error explains most “my check is short” arguments — in both directions. Comparing plans by their top rate. A 10% top tier you reach twice a year can pay less than a flat 6%; compare effective rates at your realistic sales volume. Forgetting the draw. The payout is commission minus the recovered draw, and a recoverable shortfall follows you into next month. Counting booked sales instead of collected revenue. Most plans pay on what the customer actually paid, after returns and cancellations — a clawed-back deal can reverse a commission months later. Working from a verbal plan. Rates, thresholds, caps and clawback windows belong in a signed document; if it is not written down, it is negotiable at payout time, and not in your favor.
