Work out commission in a second. Enter the sales amount, the commission rate, and any base pay — and see the commission earned and total pay.
Gross pay before taxes. Assumes a flat commission rate on the full sales amount; tiered or profit-based plans work differently.
Multiply the sales amount by your commission rate. On $10,000 of sales at a 5% rate, the commission is $500. Add any base pay for your total.
Commission = sales × commission rate
A commission plan is a formula that turns a sale into pay. The flat version this calculator models is the simplest one: a single rate applied to the whole sale amount, plus any salary or draw. It answers "what did that deal pay me" in one multiplication. What it deliberately ignores is everything that makes real plans complicated — tiers, accelerators, splits with a partner, clawbacks when a customer cancels, and whether the rate is applied to revenue or to gross profit.
The defaults are $10,000 of total sales, a 5% commission rate and $0 base pay. Rate as a decimal is 0.05, so commission is $10,000 × 0.05 = $500, and total pay is $0 + $500 = $500. Add a $2,000 monthly draw and the same deal produces $2,500 of total pay — the commission does not change, only what sits on top of it.
Now run the same $10,000 through a two-tier plan, because this is where the flat number misleads. Say the first $6,000 pays 3% and everything above it pays 7%. That is $6,000 × 0.03 = $180, plus $4,000 × 0.07 = $280, for $460 — an effective rate of 4.6%, not 5%. Tiered plans almost always pay less than the headline top rate on a deal that only just crosses the threshold, and more once you are well past it.
Typical commission rates vary enormously by industry — commonly somewhere in the 5–20% band on revenue, or a share of gross profit instead — so treat any published "average" as a starting point for a conversation, not a benchmark. Two rules travel better than any rate. First, if your plan pays on revenue, you are being paid to close volume; if it pays on gross profit, you are being paid to protect price, and discounting costs you directly. Second, if you are a contractor rather than an employee, the commission is pre-tax in a way a salaried rep's is not: on that $500, self-employment tax alone would take roughly $70 (about 15.3% on ~92.35% of net earnings) before any income tax. Budget from the after-tax number.
Reading the top tier as your rate. As above — the effective rate on a deal is usually lower than the tier you reached.
Counting commission when the deal closes, not when it is paid. Plans with clawbacks on refunds or early cancellations mean commission is not really earned until the customer sticks. Booking it as income on the close date is the fastest route to owing money back.
Forgetting the base is not free. A draw against commission is an advance, not salary. If the plan is a recoverable draw, a slow month leaves you owing the difference.
Applying the rate to the invoice total including tax or shipping. Most plans commission the product revenue only. On a $10,000 sale with $800 of tax, the 5% is $500, not $540.
One deal is arithmetic. A pipeline is bookkeeping. The moment you are tracking several deals across different stages, with tiers that depend on cumulative month-to-date sales, or you need to know what is committed versus collected, a calculator cannot hold the state — you need a sheet with a row per deal, a stage column, and a running total that drives the tier lookup. That is the job our Client Tracker & CRM does: every lead, deal and commission in one pipeline in Google Sheets or Excel. Use the calculator to check a single deal; use a sheet the moment the answer depends on what else you sold this month.
Multiply total sales by the commission rate (as a decimal). $10,000 × 5% = $500. If you also get a base salary or draw, add it for your total pay.
It varies widely by industry — often 5–20% of the sale, or a share of profit. Enter your own rate above.
