Methodology: Landing Page Conversion Calculator

1. Scope

Calculates landing-page revenue, ROI, and cost-per-conversion from traffic, conversion rate, and average order value. Deterministic — not a variance/CI model.

2. Inputs and outputs

Inputs

monthlyTraffic number
conversionRate percent
averageOrderValue number (currency)
trafficAcquisitionCost number (currency) default: 0

Outputs

conversions

traffic × conversionRate.
revenue

conversions × averageOrderValue.
roi

(revenue − trafficCost) / trafficCost.
costPerConversion

trafficCost / conversions.

Engine source: src/lib/landing-page-conversion-calculator/engine.ts

3. Formula / scoring logic

conversions         = traffic * conversion_rate
revenue             = conversions * aov
roi                 = (revenue - cost) / cost
cost_per_conversion = cost / conversions

4. Assumptions

Conversion rate is stable across traffic sources.
AOV is stable across conversions.
Traffic cost captures fully-loaded paid-acquisition spend.

5. Data sources

This tool relies on user inputs and standard arithmetic; no external benchmark data is bundled. When a question depends on an industry reference (for example, typical churn rates or hourly-wage medians), the linked adjacent tools cite their primary sources on their own methodology pages.

6. Known limitations

Vendor-reported conversion-rate benchmarks (WordStream, VWO, Unbounce) are self-selected samples from active A/B testers and overestimate medians. We do not cite them.
Does not model multi-touch attribution or assisted conversions.

7. Reproducibility

Input
traffic = 10,000, cvr = 2%, aov = $75, trafficCost = $2,000.

Expected output
conversions = 200, revenue = $15,000, roi = 650%, cost_per_conversion = $10.
