What is the Commission Calculator?

The Commission Calculator works out sales commission from the sale amount and rate — and total earnings when a base salary is part of the package.

How the Commission Calculator works

It multiplies sales by the commission rate (optionally tiered) and adds any base pay to show total compensation for the period.

commission = sales × rate%; total earnings = base + commission
  1. Enter the sales amount for the period.
  2. Enter the commission rate agreed in your plan.
  3. Add base salary if applicable, then read commission and total earnings.

Understanding the inputs

What each value means, why it matters, and a typical range — so you can fill in the calculator with confidence.

Commission Rate

The percentage of a sale paid to a salesperson or agent.

Why it matters:
It sets sales pay and how much each deal costs the business.
Typical range:
5% to 20% depending on industry and deal size.
How it affects results:
  • Higher: Stronger incentive but higher cost per sale.
  • Lower: Lower cost per sale, weaker sales incentive.

Common mistake: Applying the rate to revenue when the agreement is on profit, or vice versa.

Revenue

The total money a business earns from sales before any costs are subtracted.

Why it matters:
It is the top line - every margin and profit figure starts from revenue.
Typical range:
Varies entirely by business size.
How it affects results:
  • Higher: More to cover costs and profit, if margins hold.
  • Lower: Less to cover costs and profit.

Common mistake: Confusing revenue (sales) with profit (what is left after costs).

$10,000$300$500$1,000
$50,000$1,500$2,500$5,000

Common mistakes to avoid

  • Applying the top-tier rate to ALL sales when the plan pays tier rates per band.
  • Computing on revenue when the plan pays on margin or collected cash.
  • Ignoring clawbacks for refunds and cancellations.

Hey r/[subreddit],

I kept needing a quick mortgage calculator and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard mortgage use cases (mortgage, home, loan, payment) and links out to the formula + worked examples if you want to learn the math.
