About the Sales Commission Calculator
Calculates commission earned on a sale, supporting both a flat commission rate and a tiered/accelerator structure where a higher rate applies to the portion of a sale above a quota threshold.
- Choose flat rate or tiered/accelerator structure.
- Enter the sale amount.
- For flat rate, enter the commission %. For tiered, enter the quota threshold, base rate, and accelerator rate.
- Read the commission earned and effective overall rate.
A $50,000 sale with a $30,000 quota, 5% base rate, and 10% accelerator: $3,500 total commission — a 7% effective rate.
Real sales compensation plans vary widely — some apply accelerators retroactively to the whole sale, others cap total commission or claw it back on a cancelled deal. Check your actual comp plan.
- • An accelerator applying only to the portion above quota (as modeled here) is more common than one applying retroactively.
- • Effective rate is the easiest single number to compare across different deal sizes.
- • Watch for plan-specific caps or clawback clauses this calculator doesn't model.
