Commission Calculator
Work out commission and total take-home from any sale using a flat rate, a base-plus-commission plan, or tiered commission rates.
Example
A rep closes a $50,000 sale on an 8% flat commission plan: commission = $50,000 × 0.08 = $4,000.00. On a Base + % plan adding a $3,000 base, total earnings = $3,000 + $4,000 = $7,000.00.
How it works
Enter the sale amount and commission rate; the tool multiplies them to get commission and adds any base salary. Switch to Tiered mode to apply different rates across sale brackets.
Good to know
This Commission Calculator turns a sale amount and a pay rate into the commission you earn and your total take-home, all in one screen. It supports three plan structures: a flat percentage of the sale, a base salary plus a commission percentage, and a marginal tiered plan where the first slice of a sale pays one rate and higher slices pay progressively different rates. It is built for sales reps checking a deal payout, managers modeling a comp plan, and freelancers or affiliates who earn a cut of revenue.
Reach for it whenever you want a quick, concrete number rather than a back-of-napkin guess: before accepting a new comp plan, while comparing two job offers with different base/commission splits, or when sanity-checking a paycheck against what a closed deal should have produced. The tiered mode is especially handy for plans with accelerators, since it shows how a single large deal gets carved across brackets instead of paid at one flat rate.
To read the result, start with the big "Commission earned" figure, then look at the three stats below it. "Effective rate" is commission divided by the sale amount, so in flat mode it just echoes your rate, but in tiered mode it is the blended rate across all your brackets, which is the cleanest way to compare two plans at a glance. The "Total earnings" figure adds any base pay, and the two bars show visually how much of your pay comes from base versus commission.
One caveat to keep in mind: this is an estimate of gross commission only. Real paychecks are shaped by quotas and attainment, accelerators, draws against future commission, deal splits with teammates, clawbacks on refunds, and tax withholding, none of which this tool models. Use the number as a clean baseline, then layer in your plan's specific rules before treating it as your actual deposit.
Frequently asked questions
How is tiered (marginal) commission calculated?
Each portion of the sale is paid at the rate for its bracket. With tiers of 5% up to $10,000, 8% up to $50,000, and 12% above, a $50,000 sale pays $10,000x5% + $40,000x8% = $500 + $3,200 = $3,700, not a single flat rate on the whole amount.
What is the effective rate shown?
It is total commission divided by the sale amount. In flat mode it equals your entered rate; in tiered mode it is a blended rate across the brackets, which helps you compare plans at a glance.

People also ask
What is a typical sales commission rate?
Commission rates vary widely by industry and deal type, commonly ranging from about 5% to 20% of the sale, with software and high-margin services often higher and big-ticket or low-margin goods often lower. Many plans pair a lower base salary with a higher commission percentage, so the rate alone does not tell the whole story.
What is the difference between flat and tiered commission?
A flat plan pays one percentage on the entire sale amount, while a tiered plan splits the sale into brackets and pays each portion at its own rate. Marginal tiers (used here) mean only the dollars within a higher bracket earn the higher rate, not the whole sale.
How do I calculate commission on a base-plus-commission plan?
Multiply the sale amount by the commission rate to get the commission, then add your fixed base pay to get total earnings. For example, a $50,000 sale at 8% plus a $3,000 base equals $4,000 commission and $7,000 total.
What does effective commission rate mean?
The effective rate is total commission divided by the sale amount, expressed as a percentage. It is most useful in tiered plans because it collapses several bracket rates into one blended number you can compare against a flat-rate offer.
Is commission paid on the gross sale or the profit?
It depends on the plan: some employers pay commission on gross revenue, while others pay on gross margin or net profit after costs. This calculator computes commission on whatever sale amount you enter, so enter the figure your plan actually pays against.
Is sales commission taxed differently from regular pay?
Commission is generally treated as taxable income, though some employers apply different withholding methods to bonus or supplemental wages, which can change the amount held back from a given check. The exact treatment varies by jurisdiction and employer payroll setup.
What is a commission draw?
A draw is an advance against future commission, giving a rep guaranteed income in slow periods that is later recovered from earned commissions. This calculator shows gross commission and does not subtract draws, so your net pay may be lower if a draw is being recovered.
