Frequently Asked Questions
- How does the Commission Calculator work?
- Enter the sale amount in USD, choose a rate or flat amount, and optionally add a bonus. The calculator computes the commission based on the selected plan type (flat, percentage, marginal-tier, or retroactive-tier) and shows the effective commission rate.
- What is the difference between marginal-tier and retroactive-tier plans?
- In a marginal-tier plan, each portion of the sale amount is commissioned at the rate for that tier. In a retroactive-tier plan, the entire sale amount is commissioned at the rate of the highest tier reached. The calculator handles both.
- Can I include a bonus in the commission calculation?
- Yes, you can enter a bonus amount in USD. The bonus is added to the calculated commission, and the effective rate is adjusted accordingly.
Tips & Common Mistakes
Tips
- Ensure the sale amount is entered in USD to get accurate commission figures.

- Remember to include any bonuses separately to see their impact on total commission.
Common Mistakes to Avoid
- Confusing marginal-tier and retroactive-tier calculations, leading to incorrect commission amounts.
