Enter your sales amount — the total revenue the commission is based on.
Set your rate(s):
- Flat mode: Enter a single commission percentage.
- Tiered mode: Define brackets with thresholds and rates. The last tier automatically applies to all sales above the previous threshold.
See your results instantly — total commission, effective rate, and a tier-by-tier breakdown (in tiered mode).

The calculator auto-updates as you type, so you can experiment with different rates and structures in real time.

The Formula

Flat Rate Commission:

Commission = Sales Amount x Rate / 100

Tiered Commission:

For each tier:
  Sales in Tier = min(Remaining Sales, Tier Size)
  Tier Commission = Sales in Tier x Tier Rate / 100

Total Commission = Sum of all Tier Commissions
Effective Rate = (Total Commission / Total Sales) x 100

Example: A sales rep closes $50,000 with this tiered plan:

Tier 1: $0–$10,000 at 5% = $500
Tier 2: $10,001–$30,000 at 8% = $1,600
Tier 3: $30,001+ at 10% = $2,000
Total Commission: $500 + $1,600 + $2,000 = $4,100
Effective Rate: $4,100 / $50,000 = 8.20%

Flat vs. Tiered Commission — Which Is Better?

	Flat Rate	Tiered
Simplicity	Very simple	More complex to administer
Motivation	Consistent	Rewards higher performance
Cost predictability	Highly predictable	Variable but controllable
Best for	Simple sales cycles, new teams	Scaling teams, high-growth
Risk	May overpay on large deals	More paperwork

Key insight: Tiered plans are better for motivating top performers because the accelerating rate gives them a reason to push past each threshold. Flat rates are better when simplicity and predictability matter most.

Common Commission Rates by Industry

Industry	Typical Rate	Commission Type
Real estate	2.5–3%	Flat (per transaction)
Retail sales	3–10%	Flat or tiered
SaaS / software	8–15%	Tiered (often with accelerators)
Insurance	5–20%	Flat (varies by product)
Financial services	1–5%	Tiered (assets under management)
Wholesale / distribution	3–8%	Flat or tiered
Advertising / media	10–20%	Flat (of media spend)

Tips for Structuring Commission Plans

Align with company goals — if you want reps to sell more premium products, set higher commission rates on those products.
Keep it simple enough to explain — if a rep cannot calculate their approximate commission in their head, the plan is too complex to motivate.
Set realistic thresholds — tiered plans work best when 60–70% of reps can reach the second tier and 20–30% can reach the top tier.
Pay promptly — commission is most motivating when paid within the same pay period or within 30 days of the sale closing.
Review annually — as your business grows, commission structures should evolve with changing margins and market conditions.

Frequently Asked Questions

What is a sales commission?

A sales commission is a payment made to a salesperson based on the amount of sales they generate. It is typically expressed as a percentage of the sale price. For example, a 10% commission on a $5,000 sale would pay the salesperson $500.

What is the difference between flat and tiered commission?

Flat commission uses a single percentage for all sales — simple and predictable. Tiered commission increases the rate as salespeople hit higher thresholds, rewarding top performers. For example, 5% on the first $10,000, 8% on $10,001–$30,000, and 10% above $30,000.

How do you calculate commission?

For flat rate: Commission = Sales Amount x Rate / 100. For tiered: calculate the commission on each portion of sales that falls within each tier bracket, then sum all tiers. Our calculator handles both automatically.

What is a typical commission rate?

Commission rates vary widely by industry. Real estate agents typically earn 2.5–3%, retail salespeople 3–10%, SaaS sales reps 8–15%, and insurance agents 5–20%. The rate depends on the product value, sales cycle length, and the salesperson's role in closing.

What is an effective commission rate?

The effective commission rate is the total commission earned divided by total sales, expressed as a percentage. In tiered plans, the effective rate is always between the lowest and highest tier rates. It shows the blended rate you actually paid across all tiers.

Can commission exceed the sales amount?

No. Since commission rates cannot exceed 100%, the maximum possible commission equals the sales amount. Our calculator enforces this by capping rates at 100%. In practice, commission rates rarely exceed 20% for any single sale.
