Advertising ROAS & Profit Return

Turn attributed orders into revenue, contribution and campaign profit. Compare revenue ROAS with a clearly defined profit return and a whole-order break-even target.

Use advertising roas & profit return →

Campaign Unit-Cost Metrics

Calculate click-through rate, lead conversion and unit costs from one consistent campaign funnel, without turning those counts into a profit claim.

Use campaign unit-cost metrics →

Conversion Lift Impact

Hold visitor volume constant and compare two assumed conversion rates using contribution per conversion and a one-time implementation cost.

Use conversion lift impact →

Customer Acquisition Cost

Spread marketing, sales and allocated tools across new paying customers in the same acquisition period or cohort.

Use customer acquisition cost →

Lead Expected Value

Combine an assumed close rate with customer contribution and a handling cost paid for every lead.

Use lead expected value →

Promotion Discount & Required Volume

Calculate the whole promotional units sufficient to preserve baseline contribution after discounting every sale and paying a fixed campaign cost.

Use promotion discount & required volume →

Customer Retention & Churn

Separate the retained starting cohort from new customers still active at period end. Report customer-count retention and churn together.

Use customer retention & churn →

Customer Lifetime Contribution

Apply entered monthly churn to a starting customer cohort and compare expected revenue, variable cost and onboarding outlay over a chosen horizon.

Use customer lifetime contribution →

CAC Payback & Lifetime Ratio

Relate acquisition cost to monthly contribution and an explicitly entered paid-customer horizon, keeping payback separate from revenue.

Use cac payback & lifetime ratio →

Campaign Budget Scenario

Turn a customer target into whole leads and clicks using your conversion assumptions, then compare sufficient target cost with a strict budget ceiling.

Use campaign budget scenario →

Marketing Funnel Projection

Apply sequential visit, lead, qualification and sale rates, then extend expected revenue and contribution after campaign costs.

Use marketing funnel projection →

Before you use these calculations

Match spend, attributed results and customer counts to the same period or acquisition cohort.

Compare contribution after variable costs with acquisition spending. Revenue ROAS is not the same as profit return.

Projection inputs do not prove causality, conversion lift or future retention. Use measured counts to update the scenario.

Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
