Formula Used

Inventory COGS = Opening Inventory + Purchases − Closing Inventory

Adjusted Revenue = Revenue − Discount Amount − Returns and Allowances

Gross Profit = Adjusted Revenue − Cost of Goods Sold

Operating Profit = Gross Profit − Total Operating Costs

Earnings Before Tax = Operating Profit + Other Income − Other Expenses − Interest Expense

Tax Amount = Earnings Before Tax × Tax Rate

Net Profit = Earnings Before Tax − Tax Amount

Gross Margin = Gross Profit ÷ Adjusted Revenue × 100

Markup = Gross Profit ÷ Cost of Goods Sold × 100

Break-even Units = Fixed Costs ÷ Contribution Per Unit

FAQs

1. What does this calculator measure?

It measures adjusted revenue, cost of goods sold, gross profit, operating profit, earnings before tax, tax amount, net profit, margins, markup, unit profit, and break-even estimates.

2. Why does it compare direct and inventory-based COGS?

Some users know direct COGS immediately, while others rely on inventory movement. The calculator uses the higher value to avoid understating product costs in conservative analysis.

3. What is the difference between margin and markup?

Margin compares profit to revenue. Markup compares profit to cost. Both are useful, but they answer different pricing and profitability questions.

4. Does the tax calculation apply to losses?

No. When earnings before tax are negative, the calculator sets tax to zero. This keeps the estimate practical for quick planning and conservative review.

5. How is break-even revenue estimated?

The tool first calculates contribution per unit, then divides fixed costs by that value for break-even units. It multiplies those units by selling price per unit.

6. Can this calculator support scenario planning?

Yes. Change discounts, returns, taxes, or expense lines to test optimistic, expected, and conservative outcomes before making pricing or budgeting decisions.

7. When should I use profit per unit?

Use it when comparing products, sales channels, or campaigns. It highlights whether increased volume actually improves profitability after full expense and tax assumptions.
