38 is the example result. Read it using the units and relationship stated below.
Unit Economics uses revenue, units sold, variable cost.
Comparing financial amounts on a defined basis
For unit economics, the relationship is Result = (([Revenue] − [Variable cost]) ÷ ([Units sold])). The amount depends on the supplied revenue, units sold, rather than a live market price or a value imported from another record. A financial model is useful when its cash amounts, rate convention and time horizon describe the same case. Interest, return and purchasing power are different outputs. A projection should remain separate from an observed or audited balance.
What the model includes
Result = (([Revenue] − [Variable cost]) ÷ ([Units sold])) Check whether a rate is annual, monthly, simple or compounded. Enter fees only where the form represents them and identify contractual charges that remain outside the estimate. A monthly payment alone does not establish affordability or total ownership cost. Use the result to prepare the next question about terms or assumptions. Tax treatment, lender conditions and valuation evidence require the relevant source documents; they cannot be recovered from a few numeric inputs.
Example with the supplied inputs
Revenue: 50000; Units sold: 1000; Variable cost: 12000. Result: 38. The values are illustrative.
Compare one changed input
Revenue changes from 50000 to 55000. The result becomes 43. All other inputs remain fixed.
Calculation rule
Result = (([Revenue] − [Variable cost]) ÷ ([Units sold]))
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Revenue | 50000 | Use revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Units sold | 1000 | Use the source quantity represented by units sold. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Variable cost | 12000 | Use variable cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 38 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Revenue, Units sold, Variable cost. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Revenue on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 38.
Change Revenue from 50000 to 55000 while keeping every other value fixed. The result becomes 43. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
