Formula and cost boundary

Price = (non-percentage costs + fixed fee) ÷ (1 − fee fraction − target contribution fraction)

Combine percentage fees only when they share the same selling-price base. Include shipping, packaging and other variable costs in non-percentage cost if they are part of the margin boundary. Fee plus target share must be below 100%, with positive dollar costs; otherwise this model has no positive unique solution. Rates are your own, not platform defaults. Processor fee rounding can change the actual settlement by cents.

Worked example: User enters ten percent and thirty percent

The following inputs are hypothetical values for checking the calculation. They are not recommended prices, wages, margins or platform charges. Keep the units and period shown in each label when replacing them with your own records.

Using the result

Save the input set alongside the source date of each quote or cost record. Review the cost boundary before comparing this result with another report: a contribution measure may exclude overhead, and a cash measure follows payment dates. Display rounding does not change the underlying assumptions. Recalculate when an input changes; the tool does not predict future sales or collections.

Are any rates supplied automatically?

No. Numeric fields are your inputs. Example values demonstrate arithmetic only. Check your contracts and records for the amounts that apply to your business.

Why might a result be unavailable or negative?

A missing denominator or inconsistent inputs can make the calculation undefined. Those combinations are rejected or labeled explicitly. A valid negative result remains visible because it may identify a loss or cash shortfall.
