The Formula

Flat: Net = Sale × Rate | Tiered: Net = Σ(Tier Spanₙ × Tier Rateₙ) | Real Estate: Net = (Sale × Gross% / 2) × (1 − Franchise%) × Agent Split%

For flat structures the math is straightforward. Tiered (graduated) commissions apply increasing rates to different revenue brackets — much like income tax brackets, the blended effective rate always sits between the lowest and highest tier rate. Real estate splits follow a waterfall: franchise fee off the top of the side commission, then the remainder split between agent and broker. Adding a base salary produces On-Target Earnings (OTE).

Variable Definitions

Sale

Sale Amount / Revenue

The transaction value or gross revenue the commission is calculated from.

Rate

Commission Rate

A percentage of the sale paid to the salesperson.

Tier Span

Tier Bracket

The dollar range of the sale falling within a given tier (e.g., $0 to $50K).

Gross%

Gross Commission %

Total commission percentage paid by the seller (typically 5–6% in real estate).

Agent Split

Agent / Broker Split

The agent's share of their side commission after the broker's cut.

Base Salary

Base Salary

Fixed annual salary paid regardless of commission earnings.

OTE

On-Target Earnings

Total compensation = Base Salary + Commission (OTE in sales terminology).

How to Use This Calculator

  1. 1

    Select your commission structure: Flat Rate (straight commission), Tiered/Graduated, or Real Estate Agent Split.

  2. 2

    Enter the sale amount or total revenue for this deal.

  3. 3

    Optionally enter a base salary to see total annual compensation (OTE = salary + commission).

  4. 4

    For flat rate: just enter the commission percentage. For tiered: enter each tier limit and rate. For real estate: enter gross commission %, your agent split %, and any franchise fee.

  5. 5

    After calculating, scroll down to view the "Commission Table" — earnings at different volume levels ($5K, $10K, $25K, $50K, $100K, $250K, $500K, $1M).

Common Applications

  • Calculate total commission earnings under tiered or graduated structures to set monthly and quarterly sales targets.
  • Compare flat-rate versus tiered commission plans to understand which compensation structure benefits your income the most.
  • Determine the agent commission split after brokerage fees and franchise deductions for real estate transactions.

Flat rate applies a single percentage; tiered uses brackets; real estate follows a waterfall from gross to net.

Understanding the Concept

Tiered/graduated commission structures are the industry standard for high-performance sales roles: your first dollars earn a lower rate, and as you sell more you "graduate" into higher rates on each marginal dollar. This creates a powerful incentive to push past quotas. In real estate, the franchise fee is subtracted BEFORE the agent/broker split (the "waterfall" order of operations matters enormously — a 6% franchise fee on a 60/40 split effectively reduces the agent's share to ~56.4%). The Commission Table visualizes earnings at standard volume milestones, making it easy to set monthly sales targets.
