How do we calculate, and what are the limits?

Costs = material + hours × internal hourly cost. Selling price = costs ÷ (1 − margin / 100). Amount above costs = price − costs. Margin is not markup on costs.

Money inputs allow up to 2 decimal places; hours and percentages allow 4. Both commas and decimal points work; do not use thousands separators. Labour cost is rounded to cents, material is added, then selling price is rounded to cents. An exact half-cent rounds up. The amount above costs uses the displayed figures. The achieved margin may therefore differ slightly for small amounts.

Limits: material €1 billion, hours 1 million, rate €1 million/hour and selling price €1 trillion. Zero costs produce a zero price; a percentage margin is undefined at a zero price. The calculator does not determine market prices or replace accounting advice.
