How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Gross profit
Gross profit = revenue excluding sales taxes collected for government − cost of goods sold on the same accounting basis. Revenue and COGS must be measured consistently before the subtraction.
Tax treatment
Do not apply a generic tax percentage to both sides unless the entered figures and local accounting treatment make that adjustment valid. Tax-inclusive versus tax-exclusive treatment depends on jurisdiction, registration status and what is included in COGS.
