How it works

Simple commission = sale amount × rate. Tiered structures apply different rates to different revenue bands—enter each tier separately and sum. Gross commission income (GCI) for real estate agents is typically 2.5–3% of sale price, split with the brokerage. Self-employed agents pay self-employment tax (15.3%) on net commission income.

Input guidance

  • Use realistic rates from lender or provider quotes instead of headline averages.
  • Model conservative, baseline, and optimistic scenarios before deciding.
  • Include recurring real-world costs (fees, taxes, insurance, maintenance) where relevant.

The formula

Commission = sale amount × commission rate. Tiered plans apply different rates to different sales bands; total pay = base salary + commission earned.

Worked example

A 5% commission on $40,000 of sales is $2,000. With a $3,000 base, total pay for the period is $5,000.

More examples to test

  • Conservative case: use a higher interest rate and lower growth assumptions to stress-test affordability.
  • Optimistic case: use a lower rate with stable income assumptions to compare upside potential.

How to interpret results

Treat this as a planning model, not a final approval tool. Compare at least two scenarios and focus on total-cost and cash-flow trade-offs.

When this can be inaccurate

Results can diverge due to fees, changing rates, tax rules, lender policies, and behavior changes that simplified models cannot fully capture.

Frequently asked questions

What is a tiered commission?+

A structure where higher sales unlock higher rates — for example 4% up to a target and 6% above it — to reward top performance.

What is a draw against commission?+

An advance the employer pays that is later deducted from earned commission, smoothing income in commission-only roles.

Is commission taxed differently?+

It is taxable income like wages, though employers may withhold it at a higher supplemental rate, which can balance out at tax time.

How should I use this result?+

Treat it as a planning estimate. Compare at least two realistic scenarios, then confirm with statements, quotes, or a qualified professional before acting.

How often should I refresh assumptions?+

Refresh whenever rates, income, costs, or policy limits change materially, and before making irreversible commitments.
