2.5 is the example result. Read it using the units and relationship stated below.

Result = ((1) ÷ ([Gross margin after variable costs] ÷ 100))
Purpose

Estimate the revenue multiple needed to recover advertising spend from the margin available after other variable costs. The threshold depends on the cost scope entered. It is not a complete business profitability target.

Use a margin figure before advertising cost

Enter the percentage of revenue remaining after the variable costs you intend to include, before the advertising spend being assessed. Including that same ad spend in the margin and then using the output as an ad threshold would mix the two steps.

What break-even means here

The model uses the inverse of the entered margin fraction. Revenue at that multiple provides modeled contribution equal to ad spend. Fixed overhead, future repeat purchases and costs omitted from the margin are outside the calculation. Label those boundaries when reporting the threshold.

Set a working target with room for uncertainty

Review changes in returns, fees, product mix and fulfilment costs before adopting one threshold across campaigns. A theoretical break-even multiple leaves no allowance for expenses outside the model. A zero margin does not provide a finite recovery threshold.

Example with the supplied inputs

Gross margin after variable costs: 40. Result: 2.5. The values are illustrative.

Compare one changed input

Gross margin after variable costs changes from 40 to 44. The result becomes 2.2727. All other inputs remain fixed.

Calculation rule

Formula

Result = ((1) ÷ ([Gross margin after variable costs] ÷ 100))

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Gross margin after variable costs 40 Enter gross margin after variable costs on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs.

Output: 2.5 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

STEP 01

Collect the inputs

Gather Gross margin after variable costs. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Gross margin after variable costs 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 2.5.

Change Gross margin after variable costs from 40 to 44 while keeping every other value fixed. The result becomes 2.2727. 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.

Calculation and source notes

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.
