How to Use This Tool
Calculate the lowest price that preserves an editable contribution margin. Automated repricers can win the offer while crossing below the margin needed to sustain the order.
Why Pricing Guardrails needs more than a raw total
Fees and margin both consume selling price, so dividing by the remaining share is safer than adding percentages to cost. For this page, the useful comparison is allowed price floor, not whichever input happens to be largest. The Pricing Guardrails result answers the decision in the heading and should not be reused as a score for a different workflow.
The exact Pricing Guardrails formula
Required floor equals unit cost ÷ (1 − fee rate − target margin), capped here by the entered ceiling. The visible fields are Unit cost, Variable fees, Target contribution margin and Observed market ceiling. For Pricing Guardrails, read each printed unit before entry and make the values describe one transaction, cohort or reporting window. If those scopes differ, the displayed allowed price floor may be arithmetically valid but operationally meaningless.
Interpreting allowed price floor
Block repricing when the calculated floor exceeds the credible market ceiling. The ten-percent comparison is deliberately narrow: it tests the influence of unit cost and is neither a forecast nor a confidence interval. Preserve the values used, their dates and the resulting decision so a later reviewer can reproduce why Pricing Guardrails supported the choice.
What this Pricing Guardrails model leaves out
Fixed overhead, tax, returns, tiered fees and competitor-stock rules are excluded. That is where Pricing Guardrails stops being trustworthy. If an excluded factor could reverse allowed price floor, extend the model explicitly or use the authoritative account system instead of hiding the factor inside an unexplained adjustment.
Evidence and independent verification
The reference reviewed for Pricing Guardrails is FTC — Advertising and marketing basics. FTC — Advertising and marketing basics supports the named definition or rule but does not supply private values for allowed price floor. Before acting on the result, reconcile the worked example with the relevant dashboard, invoice, export or measurement.
Private, reproducible calculation
Pricing Guardrails runs its arithmetic in the current browser tab and requests no login or API key. That keeps the Pricing Guardrails inputs away from the site's calculation server, while leaving the user responsible for detecting stale data or a changed platform rule. When an assumption changes, reopen FTC — Advertising and marketing basics and rerun the saved Pricing Guardrails scenario.
