How it works
Price also accounts for payment fee percentage and flat fee; inspect each assumption before using the result.
Worked example
With 24 variable cost, 2 fixed cost, a 40% target margin, and 2.9% + 0.30 payment fees, the starting price is 46.06. The fee rate and flat fee are modeled separately.
Edge cases and limitations
Inputs must be finite. Negative values are accepted only where they represent a meaningful loss or cash outflow. Rounding is display-only, and results are not tax, legal, accounting, investment, or financial advice.
Frequently asked questions
Why model fees separately?
A percentage fee changes with price while a flat fee does not, so both stay visible.
