Commission Calculator
Calculate sales commission earnings with flat rate, tiered, and sliding scale structures. See your effective rate and total compensation.
Quick Answer
A flat 10% commission on a $50,000 sale earns $5,000. With a tiered structure, the effective rate changes as portions of the sale fall into different rate brackets. Add your base salary to see total compensation. Use the calculator below for flat, tiered, or sliding scale structures.

Summary
On a $50,000.00 sale with a flat commission structure, you earn $5,000.00 in commission at an effective rate of 10.00%. Combined with your $3,000.00 base salary, your total compensation is $8,000.00.
About This Tool
The Commission Calculator helps sales professionals, business owners, and recruiters quickly compute commission earnings under different pay structures. Whether you're evaluating a new job offer, negotiating commission rates, or planning your sales targets, this tool gives you instant clarity on what you'll actually earn from each sale.
Flat Rate Commission
The simplest commission structure is a flat rate, where a fixed percentage is applied to the entire sale amount. If your rate is 10% and you close a $50,000 deal, you earn $5,000 regardless of the deal size. Flat rate structures are common in real estate (typically 2.5-3% per agent), retail (1-5%), and SaaS sales (5-15% of annual contract value). The advantage of flat rate is predictability and simplicity. The disadvantage is that it doesn't incentivize reps to pursue larger deals since the percentage stays the same. Many companies pair flat rate commission with accelerators that kick in after quota is met, effectively creating a hybrid structure.
Tiered Commission
Tiered (or graduated) commission structures work like income tax brackets. Different portions of the sale amount are taxed at different rates. For example, the first $10,000 might earn 5%, the next $15,000 earns 8%, the next $25,000 earns 10%, and anything above $50,000 earns 12%. This means on a $50,000 sale, you don't earn 10% on the whole amount. Instead, you earn $500 + $1,200 + $2,500 + $0 = $4,200, giving an effective rate of 8.4%. Tiered structures are designed to reward incremental performance. They're common in enterprise software sales, insurance, and financial services where deal sizes vary dramatically. The key advantage is that every additional dollar of sales earns more commission, creating strong motivation to maximize deal value.
Sliding Scale Commission
A sliding scale differs from tiered in one crucial way: the rate for the tier your total falls into applies to the entire sale amount, not just the portion within that tier. If the tiers are 5% up to $10K, 8% for $10K-$25K, and 10% for $25K-$50K, then a $30,000 sale earns 10% on the full $30,000 = $3,000. This creates natural "cliffs" where a small increase in sales generates a disproportionate jump in commission. A $24,999 sale earns 8% = $2,000, but a $25,001 sale earns 10% = $2,500. This can be both motivating (pushing to the next tier) and frustrating (just missing a tier). Sliding scales are simpler to understand than tiered structures and are used in some real estate brokerages and car dealerships.
Base Salary + Commission
Most commission-based roles include a base salary that provides income stability regardless of sales performance. The split between base and variable compensation varies widely by industry and role. Entry-level sales development reps might have a 70/30 base-to-commission ratio, while experienced enterprise account executives often have a 50/50 split. Pure commission roles (100% variable) are rare outside of independent contractor arrangements, real estate, and certain insurance positions. When evaluating total compensation, consider not just the rates but realistic sales attainment. A company offering 15% commission but expecting $200K in annual sales gives the same commission income ($30K) as one offering 10% on $300K. The base salary is your floor; the commission is your ceiling. A higher base with lower commission suits risk-averse personalities, while a lower base with higher commission rewards top performers.
Negotiating Commission Rates
When negotiating commission structures, focus on the On-Target Earnings (OTE), which is the total compensation you'd receive if you hit 100% of your sales quota. Compare OTE across offers, not just the commission percentage. Ask about accelerators (higher rates above quota), decelerators (lower rates below quota), clawback provisions (returning commission on cancelled deals), and payment timing (when commission is actually paid, from closing through to collection). Understanding these details can mean thousands of dollars in annual difference between seemingly similar offers. This calculator helps you model different scenarios quickly so you can negotiate from a position of knowledge.
