Frequently Asked Questions
Margin is profit divided by the selling price; markup is profit divided by cost. If cost is 100 and price is 150, profit is 50: the markup is 50% but the margin is 33.3%.
Subtract the old value from the new one, divide by the old value and multiply by 100. From 80 to 100 is (100 − 80) ÷ 80 × 100 = 25%.
Divide the cost by (1 − 0.30). A cost of 700 needs a price of 1,000 for a 30% margin.
