Sales Commission Calculator
Work out commission earned from a sale amount and rate — plus total pay when you add a base salary.
How it works
commission = sales × rate ÷ 100 · total pay = commission + base salary
Commission is a flat percentage of the sales you close, so it scales one-for-one with what you sell. Adding any fixed base salary for the period gives your total take-home for that stretch. Enter sales and base on the same basis — both for the month, or both for the quarter — so the total lines up with one real paycheck.
Worked example
$5,000 in sales at a 6% rate earns $5,000 × 0.06 = $300 in commission. Added to a $2,000 base for the period, that’s $2,300 in total pay — with commission making up 13% of it.
Frequently asked questions
How do tiered or accelerator commissions work?
A tiered plan pays a higher rate once you pass a threshold — say 5% on the first $50,000 of sales and 8% on everything above it. To use this calculator for a tiered plan, compute each band separately (sales in that band × that band’s rate) and add the commissions together; the flat-rate field works for the portion inside a single tier.
Is commission calculated on revenue or profit?
It depends on the plan. Many are on gross sales (revenue), but some pay on gross margin or net profit to protect the company on discounted deals. Check which figure your plan names, and enter that number as the sales amount.
What about draws against commission?
A draw is an advance you repay from future commission, not extra money. If you take a $1,500 draw and earn $300 in commission, you still owe $1,200 against later earnings — track the draw separately, since this calculator shows what you earned, not what nets out after a draw.
