Formula and cost boundary

Incremental result = units × (later net price − current net price − added unit cost) − added fixed cost

Use net selling proceeds after each route's selling costs. This tool assumes unchanged quantity and saleability; material shrinkage or uncertain recovery needs a separate quantity schedule. Previously incurred joint production costs are shared by both alternatives and are excluded from the incremental result. Additional processing costs belong here only once. A negative result means the later route produces less value under the inputs, not that the whole product is necessarily unprofitable. The model does not predict demand or collection timing.

Worked example: Further processing adds value

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.

Inputs for this worked example
InputExample value
Same saleable quantity in both routes 1,000 units
Net selling proceeds now $8/unit
Net selling proceeds after processing $11/unit
Additional processing cost $2/unit
Additional fixed processing cost $500
Outputs from the displayed inputs
ResultCalculated value
Incremental result of further processing $500
Change in net selling proceeds $3,000
Additional processing cost $2,500

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.
