Every starting value is invented, not survey, vendor or market data. Margin is profit divided by price. Markup is profit divided by cost, so a 25% markup is a 20% margin. The price at target margin is rounded up to a whole USD. Type 2500 or 2,500; 2.5 and 2,5 are read as decimals; 1.000 is rejected as ambiguous.
