The formula
55 ÷ 45 × 100 = 122.2%
price = cost ÷ (1 − 55/100) = cost ÷ 0.45
The cost-to-price ratio at 55% margin is 0.45: cost is 45% of the price. Invert that and the price is cost × 2.2222, which is exactly a 122.2% markup. That ratio is the fastest way to price a whole list to one margin.
Price table at 55% margin
Each price is the cost divided by 0.45. The markup column stays at 122.2% on every line; only the amounts scale.

Margins near 55%
Between 45% and 65% margin the markup needed runs from 81.8% to 185.7%: it climbs faster than the margin because the cost share of the price keeps shrinking. The multiplier column turns a cost list into prices at that margin in one step.
Worked example
Suppose the landed cost is $24.99 and the buyer requires a 55% margin. The price cannot be below $55.53. At that price the profit is $30.54; below it the buyer's margin falls under 55% and the line fails their review.
The margin-as-markup trap
Rounding hides the gap on small numbers and exposes it on large ones. On a $24.99 item the difference between a 55% markup and a 55% margin is $16.80 per unit; across a container of stock it is the whole profit.
When a margin target is the right tool
Convert the 55% margin to a 122.2% markup once, then work in markup on the shop floor. Applying 122.2% to each supplier cost is faster than dividing by 0.45, and both produce the same price.
If a supplier quotes you a 55% markup, translate it before comparing: that is a 35.5% margin, 19.5 points below the 55% margin this page is about.
