Accounting Cash Flow (Per-Unit) Calculator Examples
Worked examples show how price, costs, volume, depreciation, and taxes affect estimated cash flow per unit.
These examples use the calculator's after-tax operating cash flow approach. They illustrate how volume changes the allocation of fixed costs, while price and variable cash costs affect each additional unit sold.

How to Read Your Results
Cash flow per unit is the estimated after-tax operating cash flow allocated to each unit sold.
Total accounting cash flow applies the calculation to the full period rather than one unit.
Cash flow margin shows the percentage of each sales dollar remaining as estimated accounting cash flow.
Compare scenarios using the same reporting period and consistent cost definitions.
Review negative EBIT separately from cash flow because depreciation can create a difference between the two measures.
Assumptions & Important Notes
- Each example treats fixed cash costs and depreciation as totals for the stated period.
- Taxes are estimated only on positive EBIT.
- Depreciation is added back as a non-cash expense.
- The examples exclude capital expenditure, financing cash flows, and working-capital changes.

Frequently Asked Questions
Why does cash flow per unit increase when volume rises?
If fixed period costs remain unchanged, they are allocated across more units. Variable cash costs still increase with each additional unit.
Can cash flow be positive when EBIT is negative?
Yes. Adding back non-cash depreciation can produce positive estimated operating cash flow even when EBIT is negative.
Do these examples include loan repayments?
No. The calculator excludes financing cash flows, including loan principal repayments and owner distributions.
Should I use actual or forecast costs?
Either can be used, but all inputs should relate to the same period and should be labeled consistently as actuals or estimates.
