Profitability & Mark-up vs Margin Calculator
Calculates Gross, Operating, and Net Profit Margins, alongside an exact mathematical converter between Cost Mark-up and Gross Profit Margin.
Computational Framework & Statutory Formulas
Gross Margin (%) = (Sales - Cost of Goods Sold) / Sales × 100
Mark-up (%) = (Selling Price - Cost) / Cost × 100
Margin = Mark-up / (1 + Mark-up) | Mark-up = Margin / (1 - Margin)
Nigerian Economic & Statutory Context
In an inflationary Nigerian trading environment, misunderstanding the difference between mark-up and margin causes severe underpricing. If a product costs ₦100,000 and the trader marks it up by 25% (selling at ₦125,000), the actual margin is only 20% (₦25,000 / ₦125,000), which may fail to cover operating overheads and finance charges.
Frequently Asked Questions (FAQ)
What is the fundamental difference between Mark-up and Margin?
Mark-up is the percentage added to the cost price of goods to arrive at the selling price. Margin is the percentage of the selling price that is profit. A 50% mark-up on a ₦1,000 cost results in a ₦1,500 selling price, yielding a 33.3% gross profit margin.
What is considered a healthy net profit margin for Nigerian trading and service companies?
While margins vary across industries, healthy Nigerian trading companies typically operate at gross margins of 20% to 35% and net margins of 8% to 15%, whereas professional services and tech enterprises often target net margins above 20% due to lower inventory holding costs.
