Commission = Sale × Rate
The core commission formula is simple: Commission = Sale Amount × Commission Rate. A $50,000 sale at a 5% commission rate earns $2,500. Many sales roles combine a fixed base salary with commission, so total earnings = base + commission. This calculator lets you add an optional base and shows both your commission and your effective payout rate on the sale.
Commission structures vary widely: straight commission (no base, higher rate), base-plus-commission (lower rate, steady income), and tiered plans where the rate rises after you hit a quota. Whatever the structure, the per-sale math always starts here — multiply the sale value by the applicable rate. Use this tool to check a paycheck, compare job offers, or estimate earnings before closing a deal.
No base salary — you earn only on sales, usually at a higher rate (often 7–20%). Higher risk, higher ceiling.
A guaranteed salary plus a smaller commission rate (often 2–5%). Steadier income with upside on performance.
The rate increases once you pass a quota — e.g., 4% up to $100k, 6% above. Run each tier separately and add the results.
Total earnings ÷ sale amount shows what you actually keep per dollar sold — useful when comparing base-plus plans against straight commission.
