Items kept outside operating profit

Interest, income tax, owner drawings, loan principal and long-term asset purchases are excluded. Profit is not the same as cash available.

Scenario laboratory

Test changes without rewriting your base plan.

These are sensitivity illustrations, not forecasts. A price change may affect real demand.

Methodology and important limitations

Gross margin uses revenue as its denominator. Markup uses cost of sales. Multi-product break-even assumes the entered sales mix remains stable. Monthly conversions are planning averages and do not model cash timing.
