Frequently Asked Questions — Profit Margin & Markup
What mathematical formula does the Gross Profit Margin & Markup Percentage Calculator use?
This calculator implements the verified relationship: Gross Margin % = ((Price - Cost) / Price) × 100; Markup % = ((Price - Cost) / Cost) × 100. Each variable (Unit Cost / COGS ($), Selling Price ($), Monthly Units Sold) is evaluated in real time using double-precision floating-point arithmetic so there is zero rounding drift across multi-step scenarios.
How does changing Unit Cost / COGS ($) impact the final result?
Unit Cost / COGS ($) acts as the primary driver in this model (default baseline: 32). Use the Reference Benchmark Table on this page to compare how scaling Unit Cost / COGS ($) from conservative to aggressive levels changes both the primary outcome and secondary ratios.
