Profit Margin for Business

Gross margin shows how much revenue remains after direct costs. Operating margin includes overhead. Healthy margins vary by industry: software often exceeds 70% gross margin while grocery retail may run under 30%.

Margin vs Markup

Margin = profit / revenue. Markup = profit / cost. A 25% markup on cost is only a 20% margin on revenue. Confusing the two leads to underpricing and lost profit.

Stock Trading Margin

Regulation T often allows 50% initial margin on equities: you can borrow up to half the purchase price. Maintenance margin is typically 25%. If equity falls below maintenance, you face a margin call.

Forex Margin

Leveraged currency trading requires posting margin as collateral. Higher leverage means smaller margin deposits but magnified gains and losses. This is educational math, not trading advice.

When to Use Each Mode

  • Pricing products: profit margin mode.
  • Buying stocks on margin: stock trading mode.
  • FX position sizing: currency exchange mode.

FAQ

Focus on realistic rates, terms, and any extra payments or contributions. Small changes in APR or time horizon often move outcomes more than rounding.
