Explore Advertising calculators and related business decision models on Martzine.
Advertising collects closely related calculations so you can move between specific models without returning to the top-level library.
These pages cover narrower Advertising questions and are intended to be opened when the standard calculator is not specific enough for the task.
Use the individual page for the formula, working inputs, examples, limitations and related long tail explanations.
Open the calculator that matches the decision you are reviewing. Focused sub-calculators are included where the broader model has a recurring narrower question.
Break Even ROAS uses gross margin after variable costs.
Measure clicks as a percentage of impressions. Compare the same placement and reporting period before judging a change in audience response.
Cost Per Acquisition (CPA) uses campaign spend, conversions.
CPC uses ad spend, clicks.
CPM uses ad spend, impressions.
MER uses total revenue and total marketing spend, so it is a blended business measure rather than proof that one channel caused a sale.
Compare the entered return with your marketing investment. Establish whether the return figure represents revenue or contribution before you interpret the percentage.
Compare ad-attributed revenue with advertising spend. ROAS (return on ad spend) is a revenue multiple, so read it alongside product margin and fulfilment costs.
Tell us what you are trying to build, what problem you are solving and where the digital part becomes difficult. Martzine is built around that gap. Start with the outcome and the constraint, then work back to the right digital layer.
