About the Sales Commission Calculator

Flat commission is easy arithmetic. Tiered commission is where people start disagreeing, because the higher rate normally applies only to the sales above each threshold, not to the whole total — a distinction worth thousands of dollars at the end of a good quarter.

Choose flat or tiered, enter total sales and the rates, and the commission appears immediately. Tiered mode shows the maths band by band and works out the effective rate across everything sold. Add a base salary and you get total earnings for the period alongside it.
