Operating Profit − TaxThe bottom line — what you actually keep
Net Margin %
Net Profit ÷ Revenue × 100Best single measure of overall profitability
ROI
Net Profit ÷ COGS × 100Return on cost invested into production
Maximize your bottom line
Know your 3 profit levels
Gross profit ignores overhead. Operating profit includes it. Net profit is after tax. Each requires a different fix.
Attack COGS first
A 10% reduction in COGS hits profit harder than a 10% revenue increase — it flows directly to gross profit with no extra cost.
Monitor ROI, not just profit
ROI shows how efficiently you turn cost into profit. High revenue with poor ROI signals a scaling problem, not a sales one.
Run monthly scenarios
Pessimistic planning prevents cash crunches. Model a range each quarter so you're never caught off-guard by cost spikes.
