Owners diagnosing how operating-cost layers change profit after gross profit.
Baseline and revised gross profit, operating profit, target gap and signed driver effects.
Use one ex-tax reporting period, classify each cost once and exclude finance costs and tax.
Use a different tool when: Do not use this to diagnose customer profitability after service costs; use Customer Profitability Diagnostic for that decision. Use this tool to identify which operating-cost layer changes profit after gross profit.
Profit & break-even
Baseline and revised gross profit, operating profit, target gap and signed driver effects.
Amounts use the same currency as your inputs. No currency conversion is performed.
Identify which operating-cost layer changes profit after gross profit, then compare a revised scenario with the target.
Your numbers stay in this browser
Revenue for one reporting period. Use one consistent ex-tax monetary basis.
User-classified cost of sales for the same reporting period. Use one consistent ex-tax monetary basis.
Operating labour cost outside the cost-of-sales amount. Use one consistent ex-tax monetary basis.
Rent, facilities and occupancy costs classified by the user. Use one consistent ex-tax monetary basis.
Sales and marketing operating costs for the period. Use one consistent ex-tax monetary basis.
Remaining operating costs, excluding finance costs and tax. Use one consistent ex-tax monetary basis.
Operating-profit target for the same period. Use one consistent ex-tax monetary basis.
Revised scenario change from baseline revenue.
Revised scenario change from baseline cost of sales.
Revised scenario change from labour operating costs.
Revised scenario change from occupancy operating costs.
Revised scenario change from sales and marketing costs.
Revised scenario change from admin and other operating costs.
Each output is bound to its own registered engine formula step.
Largest entered operating-cost layer: Labour. Largest adverse scenario driver: Cost of sales. Confirm both classifications before changing a budget or target; the planner does not recommend cutting the largest cost.
Each row names the assumption axis changed from the baseline.
Save these results, change an input, then compare the updated figures with this baseline.
