How do you calculate a custom order premium?

Multiply custom units by the per-unit premium and your scope factor, then add the fixed setup premium. For 12 units at $1,850 each at 100% scope plus $2,400 fixed, that is $22,200 + $2,400 = $24,600.

What is the premium per configured unit?

Divide the total premium by the number of custom units. Here $24,600 ÷ 12 = $2,050 per unit, which folds in both the per-unit charge and an allocated share of the fixed setup cost.

What does the scope-included percentage do?

It scales the variable premium when only part of the per-unit premium applies — for example 80% if half a feature is standard. At 100% the full per-unit premium is charged.

Why separate fixed from variable premium?

Fixed approval and setup cost is incurred once regardless of quantity, so spreading it over more units lowers the per-unit premium. Separating them keeps small custom runs from looking artificially cheap per unit.

Custom premium vs standard markup — what's the difference?

Standard markup covers normal product margin; the custom premium is the additional surcharge for bespoke engineering, tooling, and approval that standard pricing never anticipated.

How do I avoid under-recovering on custom orders?

Base the per-unit premium and fixed cost on actual incremental hours and tooling, not a habitual round number, and revisit them as your custom mix changes.

Configure-to-Order & Product Configuration calculator

Custom Order Premium Calculator

Custom Order Premium quantifies the surcharge a configure-to-order job should carry above standard pricing to cover the real cost of bespoke work — special engineering review, non-standard tooling, setup, and approval overhead. Quoting engineers and pricing managers use it to make sure custom configurations are not silently subsidized by standard-product margin. It matters because configure-to-order shops routinely under-recover on one-off work, eroding the very margins the configurator was supposed to protect. The calculator separates the variable per-unit premium from the fixed cost of approving and setting up a custom job, then expresses both as a per-unit figure.

What this calculator does

Estimate the premium needed for custom configured orders beyond standard option pricing.
setting a premium for nonstandard configure-to-order requests
It computes the total custom-order premium as variable (units × per-unit premium × scope) plus a fixed approval and setup charge, and the premium per configured unit.

Formula used

Variable custom order premium = custom configured units × premium required per custom unit × custom premium scope included
Total custom order premium = variable custom order premium + fixed custom approval and setup premium

Inputs explained

Custom configured units on the order:
Premium charged per custom unit:
Share of premium scope captured:
Fixed custom approval and setup premium:

How to use the result

Use it while quoting a custom or non-catalog configuration, or when reviewing whether your custom surcharges are recovering true cost.
The per-unit premium and fixed cost are your estimates of incremental cost — if they are understated, the calculator will faithfully under-price the job.
