A sales commission calculator helps sales professionals and managers understand total compensation based on different commission structures. Whether you use a flat rate, tiered brackets, or an accelerator model that rewards exceeding quota, this tool breaks down exactly how much commission is earned at every level.
Flat Rate Commission
How it works: You earn the base rate on all sales up to your quota. Sales above quota earn at base rate × the accelerator multiplier. A quota is required for accelerator mode.

How to Use the Sales Commission Calculator
Whether you are a sales rep estimating your next paycheck, a sales manager designing compensation plans, or a founder setting up your first commission structure, this sales commission calculator helps you model different scenarios quickly and accurately.
Step 1: Choose Your Commission Structure
Select one of three commission types using the tabs at the top. Flat Rate applies a single percentage to all sales. Tiered lets you define up to four brackets with increasing rates at different revenue levels. Accelerator rewards over-quota performance by multiplying your base rate on sales above the quota target.
Step 2: Enter Your Sales and Compensation Details
Enter your total sales or revenue amount. Optionally add your base salary to see total compensation (base plus commission). If you have a quota target, enter that too — the calculator will show your quota attainment percentage and, when combined with a base salary, your on-target earnings (OTE).
Step 3: Configure the Commission Rate
For flat rate, simply enter the commission percentage. For tiered structures, define each tier with a revenue threshold and its corresponding rate — the tool handles the bracket math automatically. For accelerator mode, set your base commission rate and the multiplier applied above quota (for example, 1.5x means 50% more commission per dollar over quota).
Step 4: Review Your Results
After clicking Calculate, you will see your commission earned, total compensation, effective commission rate (commission divided by total sales), and quota attainment if applicable. Tiered and accelerator modes also display a detailed breakdown table showing exactly how much commission comes from each bracket or segment.
Understanding OTE and Quota Attainment
OTE (On-Target Earnings) is the total compensation a salesperson earns when they hit exactly 100% of their quota. It equals base salary plus commission at the quota amount. Quota attainment is your actual sales divided by quota, expressed as a percentage. These are the two most important metrics in sales compensation planning — they help you benchmark offers, compare roles, and forecast earnings at different performance levels.
FAQ
Is this sales commission calculator free?
Yes, this commission calculator is completely free with no signup required. All calculations run locally in your browser — your sales figures and compensation data are never sent to any server or stored anywhere.
What is a tiered commission structure?
A tiered commission structure pays different rates at different revenue levels. For example, you might earn 5% on the first $50,000 in sales, 8% on the next $50,000, and 12% on anything above $100,000. This incentivizes higher performance by increasing the payout rate as you sell more.
What is an accelerator commission?
An accelerator commission rewards exceeding your quota with a higher rate. You earn a base commission rate on all sales up to your quota, then an accelerated (multiplied) rate on everything above it. For example, 10% base rate with a 1.5x accelerator means you earn 15% on sales beyond quota.
What is OTE (On-Target Earnings)?
OTE stands for On-Target Earnings. It is the total expected compensation when a salesperson hits 100% of their quota. OTE is calculated as base salary plus the commission earned at exactly the quota amount. It is the standard benchmark for sales compensation packages.
How is quota attainment calculated?
Quota attainment is calculated as actual sales divided by your quota target, expressed as a percentage. For example, if your quota is $200,000 and you sold $250,000, your attainment is 125%. This metric is widely used to measure sales performance and determine bonus eligibility.
What is a good commission rate for sales?
Commission rates vary widely by industry. SaaS sales reps typically earn 8-12% of annual contract value. Real estate agents commonly earn 2.5-3% of sale price. Retail commissions range from 1-10%. The right rate depends on your base salary, deal size, sales cycle length, and industry norms.
Is my compensation data private?
Yes, all calculations happen entirely in your browser using JavaScript. No data is transmitted to any server. You can verify this by using the tool offline after loading the page — it works without an internet connection because nothing is sent externally.
