Calculate the margin needed when revenue grows

Suppose a hypothetical supplier has annual revenue of KRW 10 billion and a 10% operating margin, producing KRW 1 billion of operating profit. The next year, some orders become revenue, lifting sales to KRW 12 billion, but rising production and delivery costs reduce the margin to 7%. Profit is then KRW 0.84 billion: revenue rises 20% while profit falls 16%. Keeping profit at KRW 1 billion requires about an 8.33% margin on the new revenue. Record order backlog, revenue timing and expected margin separately from budget growth.

Check for yourself

1. Am I confusing an announced budget with a company’s firm contract or current-period revenue?
2. Who bears cost increases under a fixed-price contract, and does the margin assumption reflect that?

Limits of application

This original hypothetical supplier calculation is not a forecast for a defense company or insurer. It omits financing costs, taxes, working capital and further capital expenditure. The linked insurance case has a different business model from the supplier, so its margins cannot be transferred directly.
