Use this calculator to estimate unit economics calculator from your own assumptions. The calculation runs locally in your browser, and the formula, example, scope, and source are visible below.
How to use this calculator
- Selling price / revenue per unit: enter the value for the same scenario and period as the other inputs.
- Variable cost / COGS per unit: enter the value for the same scenario and period as the other inputs.
- Acquisition cost allocated per unit/customer: enter the value for the same scenario and period as the other inputs.
- Fulfillment/service cost per unit: enter the value for the same scenario and period as the other inputs.
- Optional fixed-cost allocation per unit: enter the value for the same scenario and period as the other inputs.
- Replace the example values with values from one consistent scenario.
- Select Calculate and review the primary and supporting results.
- Change one assumption at a time when comparing scenarios, then verify material decisions against the governing source or a qualified professional.
Formula and method
contribution_before_acquisition = price - variable_cost - fulfillment_cost
unit_contribution = contribution_before_acquisition - acquisition_cost
unit_margin_pct = unit_contribution / price * 100
fully_loaded_profit = unit_contribution - fixed_cost_allocation
The implementation uses the audited A1 — Margin / Profit method. Intermediate values retain calculation precision; the interface formats values only for display unless the formula itself specifies a rounding rule.
Worked example
Inputs: Price=100; Variable cost=35; Fulfillment=10; Acquisition=20; Fixed allocation=5
Result: Contribution before acquisition=$55.00; After acquisition=$35.00; Unit margin=35.00%; Fully loaded profit=$30.00
This is the baseline audited scenario used to check that the page, formula, and displayed result remain aligned.
How to interpret the result
The calculator reports Contribution before acquisition; contribution after acquisition; unit margin; fully loaded unit profit. Treat the output as a scenario estimate: it changes when the entered scope, time period, fee basis, or cost definition changes. It does not establish a universal benchmark or guarantee a business outcome.
Assumptions and limitations
-
The result is limited to the inputs and A1 — Margin / Profit logic shown on this page.
-
Results are informational planning estimates, not accounting, tax, legal, employment, valuation, or investment advice.
-
Values are processed in the browser and are not submitted to an application server.
Common mistakes
-
Price=0.
-
duplicate CAC allocation.
-
negative costs.
-
Rounding intermediate values before completing the formula can change the final result.
-
A worked example is not a default recommendation; replace every assumption that does not match your case.
Frequently asked questions
What is the formula for Unit Economics?
The calculation applies this audited method: contribution_before_acquisition = price - variable_cost - fulfillment_cost unit_contribution = contribution_before_acquisition - acquisition_cost unit_margin_pct = unit_contribution / price * 100 fully_loaded_profit = unit_contribution - fixed_cost_allocation Display rounding is applied after the calculation rather than to intermediate values unless the rule explicitly requires it.
What inputs do I need for the Unit Economics Calculator?
Use the same period and units for these inputs: Selling price / revenue per unit; Variable cost / COGS per unit; Acquisition cost allocated per unit/customer; Fulfillment/service cost per unit; Optional fixed-cost allocation per unit. Keep optional assumptions at their example values only when those values match your scenario.
How should I interpret the result?
Read Contribution before acquisition; contribution after acquisition; unit margin; fully loaded unit profit as a planning estimate for the assumptions entered. Compare scenarios using the same scope and period; the calculator does not establish a universal target or guarantee an outcome.
What are the most common mistakes in this calculation?
For unit economics calculator, keep the input definitions consistent and review these boundary conditions: Price=0; duplicate CAC allocation; negative costs.
How this calculator was created and tested
- Formula basis: the public formula is generated from the audited implementation specification for this calculator, not inferred from a search snippet or an AI answer.
- Validation coverage: 2 of 2 release test vectors are marked Audited for this calculator. The suite covers a normal scenario plus boundary or invalid-input behavior where defined.
- Regression behavior: build checks compare expected outputs, validation states, route integrity, structured data, internal links, and release blockers before publication.
- Automation and AI: automation or AI may assist drafting, organization, and regression work, but it is not treated as an authoritative source and does not override the audited formula, official rate registry, or release blockers.
- Editorial responsibility: MIASIN S.R.O. controls publication, source policy, corrections, and release decisions. No named individual expert review is claimed unless a page explicitly identifies one.
